Rhagophthalmidae Olivier, 1907 (Coleoptera, Elateroidea): described genera and species, current problems, and prospects for the bioluminescent and paedomorphic beetle lineage

Authors:

Abstract and Figures

Rhagophthalmidae are a small beetle family known from the eastern Palaearctic and Oriental realms. Rhagophthalmidae are closely related to railroad worms (Phengodidae) and fireflies (Lampyridae) with which they share highly modified paedomorphic females and the ability to emit light. Currently, Rhagophthalmidae include 66 species classified in the following 12 genera: Bicladodrilus Pic, 1921 (two spp.), Bicladum Pic, 1921 (two spp.), Dioptoma Pascoe, 1860 (two spp.), Diplocladon Gorham, 1883 (two spp.), Dodecatoma Westwood, 1849 (eight spp.), Falsophrixothrix Pic, 1937 (six spp.), Haplocladon Gorham, 1883 (two spp.), Menghuoius Kawashima, 2000 (three spp.), Mimoochotyra Pic, 1937 (one sp.), Monodrilus Pic, 1921 (two spp. in two subgenera), Pseudothilmanus Pic, 1918 (two spp.), and Rhagophthalmus Motschulsky, 1854 (34 spp.). The replacement name Haplocladon gorhami Kundrata, nom. nov. is proposed for Diplocladon hasseltii Gorham, 1883b (described in subgenus Haplocladon) which is preoccupied by Diplocladon hasseltii Gorham, 1883a. The genus Reductodrilus Pic, 1943 is tentatively placed in Lampyridae: Ototretinae. Lectotypes are designated for Pseudothilmanus alatus Pic, 1918 and P. marginalis Pic, 1918. Interestingly, in the eastern part of their distribution, Rhagophthalmidae have remained within the boundaries of the Sunda Shelf and the Philippines demarcated by the Wallace Line, which separates the Oriental and Australasian realms. This study is intended to be a first step towards a comprehensive revision of the group on both genus and species levels. Additionally, critical problems and prospects for rhagophthalmid research are briefly discussed.

Introduction
Rhagophthalmidae are a small elateroid family distributed in South, East, and South-
east Asia (Wittmer 1979; Kawashima et al. 2010; Kundrata and Bocak 2011a; Ka-
zantsev 2012). Soft-bodied males are capable of ight, whereas all known females are
strongly paedomorphic and remain larva-like as adults (Fig. 1). Predaceous larvae oc-
cur in soil and leaf litter where they feed on millipedes. Both larvae and adults are bio-
luminescent, although the biology and ecology of most species are unknown (Li and
Liang 2008; Kawashima et al. 2010). Rhagophthalmidae have a convoluted history of
classication. Most genera were originally placed either in Lampyridae or the widely
dened Drilidae (currently Drilini in Elateridae: Agrypninae; Kundrata and Bocak
2011b). e separate family Rhagophthalmidae was proposed by Olivier (1907, 1910)
for genera which had antennae with 12 antennomeres and more or less emarginate
eyes. However, since their erection, the composition and classication of Rhagoph-
thalmidae have varied greatly, and various authors have recognized 3–11 genera in the
group. At various times, the majority of Rhagophthalmidae have been considered ei-
ther a subgroup of Lampyridae (e.g., McDermott 1964, 1966) or Phengodidae (Crow-
son 1972; Lawrence and Newton 1995; Bocak 2007), or a separate family close to
one of the two above-mentioned families (Olivier 1910; Winkler 1925; Wittmer and
Ohba 1994). Recent phylogenomic approaches suggest Rhagophthalmidae are sister
to Phengodidae, and both are closely related to Lampyridae, Sinopyrophoridae, and
Elateridae (Zhang et al. 2018; Douglas et al. 2021; Kusy et al. 2021; Cai et al. 2022).
e early history of Rhagophthalmidae systematic research dates back to 1849,
when Westwood (1849) described Dodecatoma Westwood, 1849 based on a single
species from India. Motschulsky (1854) then described Rhagophthalmus Motschulsky,
1854 based on one species from China, and Pascoe (1860, 1862) added Dioptoma
Pascoe, 1860 and Ochotyra Pascoe, 1862 from Bangladesh and India, respectively.
While Dodecatoma was placed in the widely delimited Drilidae, the remaining genera
were classied in Lampyridae (e.g., Gemminger 1869). Gorham (1883a, b) described
Diplocladon Gorham, 1883 and its subgenus Haplocladon Gorham, 1883, both from
Indonesia, and placed them in Drilidae.
Several new species of Rhagophthalmus from Southeast Asia, India, and China were
added by Olivier (1885) and Fairmaire (1889, 1896, 1899). Gorham (1895) described
the second species of Dodecatoma from India, and classied Dioptoma, Diplocladon,
Dodecatoma, Haplocladon (originally as a subgenus), and Ochotyra in Drilinae. He later
described a second species of Haplocladon, which was collected in India (Gorham 1903).
Olivier (1907) erected the family Rhagophthalmidae for Dioptoma, Ochotyra, and
Rhagophthalmus. In 1910, he provided the rst catalogues for Rhagophthalmidae and
Drilidae (Olivier 1910), with the latter including Diplocladon (with Haplocladon as a
Annotated catalogue of Rhagophthalmidae Olivier, 1907 (Coleoptera, Elateroidea) 57
synonym) and Dodecatoma. Jakobson (1911) included many soft-bodied groups, including
“Rhagophthalmini”, in his “Cantharididae”. Olivier (1912) revised Rhagophthalmus and
recognized 12 species, ve of which were newly described from China and Sri Lanka.
Gahan in Morice (1913) reported a new species of Dioptoma from Sri Lanka.
Many new taxa currently belonging to Rhagophthalmidae were then described
by the French coleopterist Maurice Pic, a person famous for his usually short and
uninformative descriptions (e.g., Villiers 1958; Bezděk and Regalin 2015). Pic
described the following taxa from Asia: one new species of Dioptoma and four species of
Rhagophthalmus from India, Sri Lanka, China, and Indochina (Pic 1916, 1917, 1925a,
b); genus Pseudothilmanus Pic, 1918, with its monotypic subgenus Drilothilmanus
Pic, 1918 from northern India (Pic 1918); genus Bicladodrilus Pic, 1921, with two
species from the Philippines and Vietnam (Pic 1921a, 1923); genus Bicladum Pic,
1921, with two species from Borneo and Sumatra (Pic 1921b, 1930a); a new variety
and a new species of Dodecatoma from Indonesia and the Philippines, respectively (Pic
1921b, 1924); a new variety of Diplocladon from Indonesia (Pic 1921b); a new genus
Monodrilus Pic, 1921 from Indonesia (Pic 1921b) and subsequently the monotypic
subgenus Dodecatomorpha Pic, 1928 from Vietnam (Pic 1928); and a monotypic
Mimoochotyra Pic, 1937 from Indonesia. Pic (1937) also erected Falsophrixothrix Pic,
1937 for two species from Indonesia, one of which was already described by Pic in the
genus Phrixothrix Olivier, 1909 (currently in Phengodidae; Pic 1914).
Later, Wittmer (1939, 1944) added another three species from Indonesia and Sin-
gapore to Falsophrixothrix, with one being new and two transferred from Phrixothrix
(Olivier 1911; Pic 1921a). Wittmer (1944) published a comprehensive catalogue of
genera and species in Drilidae in which he listed many genera that are currently in
Rhagophthalmidae, i.e., Bicladodrilus, Bicladum (as Bicladon [sic!]), Diplocladon (with
Haplocladon as a synonym), Dodecatoma, Falsophrixothrix, Mimoochotyra, Monodrilus,
and Pseudothilmanus. Pic (1951) described an additional species of Falsophrixothrix
from Vietnam. In his major works on Lampyridae, McDermott (1964, 1966) included
Dioptoma, Mimoochotyra (as Mimochotyra [sic!]), Ochotyra, and Rhagophthalmus in the
subfamily Rhagophthalminae.
Crowson (1972) redened Drilidae to include only a few core genera. Although
Crowson excluded the majority of genera from Drilidae, he did not suggest any family
placement for many, which left them in an uncertain position. Crowson (1972) also redened
Phengodidae by including Cydistus Bourgeois, 1885 as well as genera which are currently
in Rhagophthalmidae, i.e., Dioptoma, Diplocladon, Falsophrixothrix, and Rhagophthalmus.
Lawrence and Newton (1995) distinguished the subfamily Rhagophthalminae within
Phengodidae, and included the genera Cydistus, Dioptoma, Diplocladon, Dodecatoma,
Falsophrixothrix, Mimoochotyra (as Mimochotrya [sic!]), Ochotyra (as Ochotrya [sic!]),
and Rhagophthalmus. Other major works on Rhagophthalmidae were those by Walter
Wittmer, who described three new species of Dodecatoma from Afghanistan, India, and
Nepal (Wittmer 1979, 1995), synonymized Ochotyra with Rhagophthalmus (Wittmer
and Ohba 1994), and described eight new species of Rhagophthalmus from China, Japan,
and Myanmar (Wittmer and Ohba 1994; Wittmer 1997).

Kawashima (1998) described the morphology of a larviform adult female of
Rhagophthalmus. He also erected Menghuoius Kawashima, 2000 for two Chinese
species originally classied in Rhagophthalmus, and later described the third species
of that genus from Myanmar (Kawashima 2000, 2002). Kawashima and Satô (2001)
described three species of Rhagophthalmus from Myanmar, Taiwan, and ailand,
and Kawashima and Sugaya (2003) added an additional new species from Taiwan.
Branham and Wenzel (2003) studied the evolution of bioluminescence in the soft-
bodied elateroids (i.e., “cantharoids”) and conrmed that Rhagophthalmus is closely
related to Dioptoma and Diplocladon. Li and Liang (2008) described the morphology
of a larviform adult female of Diplocladon from China. Li et al. (2008a) described two
new species of Rhagophthalmus from China, provided information on the morphology
and distribution for several other species, and provided a distribution map for all
species in China and surrounding regions.
In the Rhagophthalmidae chapter of the Handbook of Zoology, Kawashima et al.
(2010) included only Dioptoma, Diplocladon, Dodecatoma, Menghuoius, Mimoochotyra
(as Mimochotyra [sic!]), and Rhagophthalmus. Kundrata and Bocak (2011a) revised
the long-neglected genus Pseudothilmanus (with its subgenus Drilothilmanus, which
they synonymized with Pseudothilmanus), added it to Rhagophthalmidae, and also
listed Bicladodrilus, Bicladum (as Bicladon [sic!]), Dioptoma, Diplocladon, Dodecatoma,
Falsophrixothrix, Mimoochotyra (as Mimochotyra [sic!]), Monodrilus, Reductodrilus, and
Rhagophthalmus (including Menghuoius and Ochotyra). Ho et al. (2012) described two
new species of Rhagophthalmus from Taiwan. Kazantsev (2012) described two species
of Dodecatoma from India and Nepal. Most recently, Yiu (2017) described a new
species of Diplocladon and a new species of Rhagophthalmus from Hong Kong. Roza
(2020) added information on the morphology and distribution of Pseudothilmanus.
Besides research on the diversity, systematics, and morphology of Rhagophthalmi-
dae, many studies in the 21st century have focused on their bioluminescence (Ohmiya
et al. 2000; Ohba 2004a; Chen et al. 2010; Oba et al. 2011; Oba 2015; Liu et al.
2020) and embryogenesis (Kobayashi et al. 2001, 2002, 2003). Additionally, the rapid
development of molecular phylogenetic methods in the last decades has enabled scien-
tists to test the phylogenetic placement of Rhagophthalmidae within Elateroidea using
one or several markers (e.g., Suzuki 1997; Bocakova et al. 2007; Sagegami-Oba et al.
2007; Stanger-Hall et al. 2007; Kundrata and Bocak 2011b; Kundrata et al. 2014;
McKenna et al. 2015), mitogenomes (Li et al. 2007; Amaral et al. 2016; Chen et al.
2019), or a phylogenomic approach (Zhang et al. 2018; Amaral et al. 2019; Douglas
et al. 2021; Kusy et al. 2021; Cai et al. 2022).
Despite the long history of rhagophthalmid systematic research, we lack a com-
prehensive study which would summarize all relevant information of all genera and
species in the group. erefore, in this study, we provide an annotated catalogue of
genera and species of Rhagophthalmidae, including information on their synonyms,
type material, distribution, and bibliography. We believe this study will serve as a ro-
bust framework for subsequent taxonomic revisions of all genera in addition to studies
devoted to diversity, evolution, nature conservation, and ecology of the group.

Materials and methods
Names of family-, genus-, and species-group taxa are given with the name of the au-
thor, and the year and page of publication. e page given is the page where the taxon
name and description are printed. e year and page given for the incorrect subsequent
spellings are the rst year and page in which they are used. Incorrect subsequent spell-
ings not in prevailing usage are unavailable (ICZN 1999, Art. 33.3). Complete data
and comments for genus-group names are presented with the lowest-rank name, i.e.,
subgenus rather than genus, since these criteria follow the Principle of Coordination
(ICZN 1999, Art. 36.1 and 43.1).
We provide the type species for each genus-group name, including information on
its designation. We follow Recommendation 73F of the Code (ICZN 1999) and pro-
vide lectotype designations to x the species identity for two species of Pseudothilmanus
Pic, 1918. ese species were originally described based on an unknown number of
specimens, then redescribed (Kundrata and Bocak 2011a) under the assumption that
the original descriptions were based only on holotypes. We do not provide lectotype
designations for species in other genera, as they must rst be revised in detail. Under
each name, the currently valid name is listed rst, followed by synonyms in chrono-
logical order.
Misspellings and unavailable names are followed by a colon “:”. We list all relevant
references known to us for all genera, as well as for the family Rhagophthalmidae,
particularly those that include information on systematics, classication, phylogeny,
biology, and ecology. Since PhD or any other student theses are not ocially published
in the sense of the Code (ICZN 1999), we list only the relevant works (i.e., Ho 2002;
Jeng 2008; Roza 2022) at the end of the Literature sections under each genus and spe-
cies. Dates of publications and exact bibliographic references (especially problematic
ones, often not cited uniformly by researchers) are taken from the following compre-
hensive general works: Chandler (2000); Bouchard et al. (2011); Bousquet (2016);
and Evenhuis (2020). For the date of publication of F. P. Pascoe’s description of the
genus Dioptoma (Pascoe 1860), we follow Evenhuis (2020).

In addition to the aforementioned literature, Rhagophthalmidae were mentioned in
some student works, e.g., PhD theses by Ho (2002), Jeng (2008), and Roza (2022).
Remarks. As dened here, Rhagophthalmidae include 12 genera (one of them
with two subgenera) and 66 species distributed primarily in East, South, and Southeast
Asia, with a few species found on the border of South and Central Asia (i.e., Afghani-
stan). Males can be recognized by antennae with 12 antennomeres, with antennomere
III longer than antennomere II. In cases where the antennae are serrate or pectinate,
antennomere III is not simple, i.e., the serration or rami begin on antennomere III.
Females are more (e.g., Diplocladon or Haplocladon; see Remarks under these genera)
or less (e.g., Rhagophthalmus) larviform (for more information, see Kawashima et al.
2010). Known larvae are predators of millipedes, similar to larvae of the closely related
Phengodidae. Although Rhagophthalmidae were credited by McDermott (1966) to
“Olivier, 1902”, we found no evidence of the publication to which McDermott re-
ferred, similar to Lawrence and Newton (1995: 858).

Remarks. is genus currently contains two described species from the Philip-
pines and Vietnam, respectively. e generic assignment of a specimen reported as
Bicladodrilus sp.” from China, which was used in the molecular phylogenetic analyses
by Bocakova et al. (2007), Bocak et al. (2008, 2018), Levkanicova and Bocak (2009),
and other studies, needs a careful re-examination. Bicladodrilus is similar to Bicladum
and Diplocladon in having strongly bipectinate antennae and long elytra. is generic
complex is in need of revision.

Remarks. is genus currently contains two described species from Bangladesh,
India, and Sri Lanka. Males are characterized by short antennae and deeply emarginate
eyes, each with a smaller upper portion and a larger lower portion (Fig. 1B). Regarding
the gender of Dioptoma, Pascoe (1860) treated it as feminine and since the name is not
a Greek noun, here we follow Pascoe’s decision.

Dioptoma greeni Gahan in Morice 1913: cxviii. Synonymized with D. adamsii (as a
variety) by McDermott (1966: 122). McDermott (1966) attributed the name
D.greeni to Gahan (1908a: xlviii); however, there is no such name in that publica-

Remarks. See more information on Haplocladon, which was once considered a
subgenus of Diplocladon (Gorham 1883b) or even its synonym (e.g., Wittmer 1944),
under the genus name Haplocladon below. Some authors who mentioned Diplocladon
were actually probably referring to Haplocladon (for more details, see Remarks under
D. hasseltii). Diplocladon currently contains two described species, one from China and
one from Indonesia. It is similar to Bicladodrilus and Bicladum in having strongly bipec-
tinate antennae (Fig. 1C) and long elytra. is generic complex is in need of revision.

washima et al. 2010), are probably members of Haplocladon. We are aware of several
Haplocladon specimens from Singapore (deposited in NHMUK) but no Diplocladon
are known from that area.

Remarks. Dodecatoma currently contains eight described species from Afghani-
stan, India, Nepal, Indonesia, and the Philippines. is genus is in need of revision;
taxa from Southeast Asia should be removed from Dodecatoma, and the generic as-
signment of the species with serrate antennae described recently by Kazantsev (2012)
needs careful re-examination (the remaining species of Dodecatoma, including the type
species, have pectinate antennae).

Remarks. Falsophrixothrix currently contains six described and several undescribed
species from Southeast Asia. It can be recognized by its small body size, strongly bi-
pectinate antennae (Fig. 1D), and usually shortened elytra which do not cover the
entire abdomen. It should be noted that all previous authors treated the gender of
Falsophrixothrix as masculine; however, -thrix (hair in Greek) is feminine.

Genus Haplocladon Gorham, 1883
Haplocladon Gorham, 1883b: 249 [as a subgenus of Diplocladon Gorham, 1883].
Gender: neuter. Type species. Haplocladon gorhami Kundrata, 2022, nom. nov.
[replacement name for Diplocladon hasseltii Gorham, 1883b]; by monotypy.
Literature. Gorham (1883b: 249): original description; Gorham (1895: 310): re-
mark; Gorham (1903: 330): species description; Olivier (1910: 8): catalogue; Wittmer

and Liang (2008: 109): remark [as D. haplocladon [sic!]]. In addition to the aforemen-
tioned literature, this genus was included in a PhD thesis by Jeng (2008).
Remarks. Gorham (1883b) originally described Haplocladon as a subgenus of
Diplocladon but later treated it as a separate genus (Gorham 1895, 1903). Unfor-
tunately, he named type species of both Diplocladon and Haplocladon as “hasseltii
(Gorham 1883a, b), which probably confused some subsequent authors who treated
Haplocladon as a synonym of Diplocladon (Olivier 1910; Wittmer 1944; Li and Liang
2008). Crowson (1955) and Paulus (1972) again considered Haplocladon a separate
genus. Since Haplocladon diers at rst sight from Diplocladon by the unipectinate an-
tennae (versus bipectinate in Diplocladon), we prefer to keep Haplocladon at a generic
level. Because Diplocladon hasseltii Gorham, 1883a and Diplocladon hasseltii Gorham,
1883b (described in subgenus Haplocladon) are primary homonyms, the latter junior
name is permanently invalid (Art. 57.2 of the Code; ICZN 1999) and should be re-
placed by a new name (see below). Currently, Haplocladon contains two species, one
from Indonesia and one from southern India. Based on the available gures, specimens
reported by Haneda (1950) from Singapore and identied as Diplocladon hasseltii,
which were later mentioned by other authors (e.g., Harvey 1952; Haneda 1955; Lloyd
1971; Lloyd 1978; Crowson 1981; Haneda 1985; Kawashima et al. 2010), are prob-
ably members of Haplocladon.
Haplocladon gorhami Kundrata, nom. nov.
Replacement name for Diplocladon hasseltii Gorham, 1883b.
Diplocladon hasseltii Gorham, 1883b: 250 (described in subgenus Haplocladon). Preoc-
cupied by Diplocladon hasseltii Gorham, 1883a: 6.
Haplocladon haselti: Gorham 1903: 330 [unavailable name, incorrect subsequent spell-
ing not in prevailing usage].
Type depository. Described based on an unknown number of specimens. Two syn-
types, males (one from Sumatra, one from Java) (RMNH).
Type locality. Indonesia: Sumatra, Lampung, Soekadana; Java, Batavia.
Distribution. Indonesia (Sumatra, Java).
Literature. Gorham (1883b: 250): original description; Gorham (1903: 330): re-
mark [as H. haselti [sic!]]; Olivier (1910: 8): catalogue [as D. hasselti]; Wittmer (1944:
211): catalogue [as D. hasselti].
Remarks. Gorham (1883b: 250) also reported an unnamed variety of H. hasseltii
as “var. totum testaceum” (i.e., colour description but not the ocial name of the va-
riety) from Ardjoeno and Batavia in Java. At least one specimen from Batavia labelled
as “var.” is present in MNHN. Two specimens from Ardjoeno and one specimen from
Batavia deposited in RMNH bear the label “Type”; however, based on Article 72.4.1.
of the Code (ICZN 1999), they should not be considered a part of the type series for
Haplocladon gorhami.

Genus Menghuoius Kawashima, 2000
Menghuoius Kawashima, 2000: 132. Gender: masculine. Type species. Rhagophthalmus
ingens Fairmaire, 1896, by original designation.
Menghouius: Bocak 2007: 225 [unavailable name, incorrect subsequent spelling not in
prevailing usage].
Menhuoius: Li et al. 2008a: 264 [unavailable name, incorrect subsequent spelling not

mar,Vietnam.
Literature. Kawashima (2000: 132): original description; Kawashima (2002:

habitus, and female bioluminescence. In addition to the aforementioned literature,
this genus was included in a PhD thesis by Jeng (2008).
Remarks. Menghuoius currently contains three described species from China,
Myanmar, and Vietnam. It is similar to Rhagophthalmus in habitus, short, serrate
antennae, and deeply emarginate eyes but diers in the large size and robust mandibles
(Kawashima 2000). Menghuoius was implicitly considered a junior synonym of
Rhagophthalmus by Li et al. (2008a) based on the similar morphology of females of both
genera. However, since the morphology of highly paedomorphic, larva-like females of
Rhagophthalmidae is much less informative than the morphology of adult males, we
consider Menghuoius a separate genus until a detailed revision of Rhagophthalmus and
related genera is carried out.

Indonesia. According to Pic (1937), it is characterized by having serrate antennae with
thickened median antennomeres, and relatively long elytra. e specimen identied
as Mimochotyra [sic!] and used in the molecular phylogenetic analyses by Bocakova et

Genus Monodrilus Pic, 1921
Monodrilus Pic, 1921b: 12. Gender: masculine. Type species. Monodrilus marginatus
Pic, 1921; by monotypy.
Remarks. Monodrilus has more or less serrate antennae and relatively long elytra, and
currently contains two species from Indonesia (Java) and Vietnam, respectively, each in
a monotypic subgenus. Following Wittmer (1944), we retain the concept of Monodrilus
with two subgenera; however, Pic (1930b) already suggested Dodecatomorpha could be
a separate genus. A proper taxonomic revision should be conducted to resolve the
status of Dodecatomorpha.

In addition to the aforementioned literature, this genus was included in PhD theses
by Ho (2002), Jeng (2008), and Roza (2022).
Remarks. Rhagophthalmus is the most speciose genus in the family. It contains
34 species from South, East, and Southeast Asia. is genus is characterized by
having deeply emarginate eyes and relatively short antennae (Fig. 1E, F). Wittmer
in Wittmer and Ohba (1994) synonymized Ochotyra with Rhagophthalmus, and we
follow this concept until a proper revision of the genus is carried out. On the other
hand, Menghuoius, which was synonymized with Rhagophthalmus by Li et al. (2008a),
is considered here a separate genus (see Remarks under Menghuoius).

Cydistus Bourgeois, 1885 [Phengodidae: Cydistinae]
Cydistus Bourgeois, 1885: 272. Type species. Cydistus reitteri Bourgeois, 1885; by monotypy.
Composition and distribution. Six described species from Asia Minor, the Levant,
Iraq, and Iran: Cydistus chindaaricus Bolívar y Pieltain, 1913, C. escalerai Bolívar y
Pieltain, 1913, C. nigripennis Wittmer, 1979, C. persicus Bolívar y Pieltain, 1913,
C.reitteri Bourgeois, 1885, and C. zurcheri Bourgeois, 1908 (Kundrata et al. 2019).
Remarks. Cydistus was originally placed in Drilidae (Olivier 1910; Wittmer 1944).
Later, Crowson (1955) hypothesized Cydistus might be an intermediate form between
Karumiidae (currently a subfamily in Dascillidae) and Phengodidae. Although Paulus
(1972) erected Cydistinae within Karumiidae for Cydistus, Crowson (1972) transferred
this genus into the widely delimited Phengodidae, which also included Rhagophthal-
midae. Lawrence and Newton (1995) and Bocak (2007) classied Cydistus in Phengo-
didae: Rhagophthalminae. Lawrence et al. (2010a, b) and Lawrence (2016) considered
Cydistinae in Elateriformia incertae sedis. Finally, Kundrata et al. (2019) were the rst
to include Cydistinae in a molecular phylogenetic analysis, and found them sister to
the New World Phengodidae, which are only distantly related to Rhagophthalmidae.
is placement was conrmed by a morphology-based analysis by Roza (2022).

Distribution. New Caledonia, Solomon Islands.
Remarks. is rey species was originally described in Luciola Laporte, 1833
(Bourgeois 1884) and later transferred to Rhagophthalmus by Olivier (1902). e same
author later placed this species in his new genus Bourgeoisia Olivier, 1908, and McDer-
mott (1966) subsequently designated it the type species of this genus. Bourgeoisia is
currently considered a synonym of Luciola (e.g., Ballantyne and Lambkin 2013; Ballan-
tyne et al. 2019). For more information on L. antipodum see e.g., McDermott (1966);
Ballantyne (1968); Ballantyne and Lambkin (2013); and Ballantyne et al. (2019).

Reductodrilus Pic, 1943 [Lampyridae: Ototretinae]
Reductodrilus Pic, 1943: 9. Type species. Reductodrilus nigroapicalis Pic, 1943; bymonotypy.
Composition and distribution. Only a single species, R. nigroapicalis Pic, 1943
from northern Borneo (Malaysia: Sabah). Reductodrilus nigroapicalis var. latetestaceus
Pic, 1943 should have a subspecic status according to Article 45.6.4. of the Code
(ICZN 1999).
Remarks. Reductodrilus was initially placed in Drilidae (Pic 1943; Wittmer 1948).
After most Drilidae genera were transferred to dierent families (e.g., Lampyridae,
Lycidae, Omethidae, and Rhagophthalmidae) by Crowson (1972), Reductodrilus re-
mained in an uncertain position. Kundrata and Bocak (2011a) listed it in Rhagoph-
thalmidae in their revision of Pseudothilmanus. Probable syntypes of both subspecies of
R. nigroapicalis are deposited in MNHN. Here, we tentatively transfer Reductodrilus to
Lampyridae: Ototretinae based on its suboval and somewhat attened body, antennae
with 11 antennomeres which clearly extend beyond the posterior pronotal margin, head
partially covered by pronotum, eyes clearly separated by frons, pronotum transverse,
medially elevated, with anterior angles inconspicuous, rounded, and posterior angles
projected posteriad (for more details see Janisova and Bocakova 2013). A detailed revi-
sion of this genus should improve our understanding of its systematic position.
Discussion
Although Rhagophthalmidae have been known to entomologists for more than a cen-
tury, their taxonomy and classication are still poorly known. e number of genera in-
cluded in Rhagophthalmidae and also their placement within Elateroidea classication
vary by source (e.g., McDermott 1966; Crowson 1972; Lawrence and Newton 1995;
Kawashima et al. 2010; Kundrata and Bocak 2011a). In the last decade, Elateroidea sys-
tematic research has accelerated and the classication of the superfamily has experienced
many taxonomic changes (e.g., Kundrata et al. 2014, 2019; Bocak et al. 2018; Kusy
et al. 2018b, 2021), including the discoveries of two new recent families (Bocak et al.
2016; Rosa et al. 2020) and one new extinct family (Li et al. 2021b). However, only six
new species of Rhagophthalmidae were described in three taxonomic papers in the same
period (Ho et al. 2012; Kazantsev 2012; Yiu 2017). is is especially striking when com-
pared to the most closely related family of Rhagophthalmidae (i.e., Phengodidae), where
numerous taxonomic studies were published (e.g., Constantin 2014, 2016; Zaragoza-
Caballero and Hernández 2014; Roza et al. 2017, 2018; Roza and Mermudes 2019,
2020; Vega-Badillo and Zaragoza-Caballero 2019; Vega-Badillo et al. 2020, 2021a, b),
including not only descriptions of several new genera and species but also phylogenetic
analyses of the group (Zaragoza-Caballero and Zurita-García 2015; Quintino 2017;
Kundrata et al. 2019; Roza 2022). In Rhagophthalmidae, the most important research
topics include taxonomic limits, phylogenetic relationships, accurate dating of the origin
Annotated catalogue of Rhagophthalmidae Olivier, 1907 (Coleoptera, Elateroidea) 105
of the group, the evolution of bioluminescence and paedomorphosis, systematics of all
genera (including revisions of already known species as well as descriptions of new taxa),
descriptions of paedomorphic females and immature stages for all genera and species,
and evaluating the distribution of the group at both generic and family levels.
Phylogenetic relationships, origin, and monophyly of Rhagophthalmidae
e phylogenetic placement of Rhagophthalmidae within Elateroidea has been con-
troversial based on morphology only (Crowson 1972; Lawrence 1988; Branham and
Wenzel 2001; Lawrence et al. 2011), and Rhagophthalmidae were often placed either
in or close to Lampyridae or Phengodidae. Molecular phylogenetic analyses using vari-
ous datasets and analytical approaches repeatedly conrmed that Rhagophthalmidae
are sister to Phengodidae (Bocakova et al. 2007; Kundrata and Bocak 2011b; Kundrata
et al. 2014; Zhang et al. 2018; Douglas et al. 2021; Kusy et al. 2021; Cai et al. 2022).
Both families share soft-bodied males with large eyes, often bipectinate antennae with
12 antennomeres, leathery elytra which are usually shortened and narrowed, larvi-
form females, and larvae that possess bioluminescent organs and feed on millipedes
(Kawashima et al. 2010; Zaragoza-Caballero and Hernández 2014; Kundrata et al.
2019). Kusy et al. (2021) dened the “lampyroid clade”, which contains Lampyridae,
Phengodidae, Rhagophthalmidae, and Sinopyrophoridae. Fossil Cretophengodidae
were probably also a part of that clade (Li et al. 2021b).
e date of the origin of Rhagophthalmidae is unclear, as there are no known fos-
sils of the group. Generally, soft-bodied elateroids are rarely found as fossils, and to
date, the most informative fossils are inclusions in various ambers. Cretophengodidae
were described from mid-Cretaceous amber of northern Myanmar (ca. 99 Mya, Shi et
al. 2012; Li et al. 2021b), and Kusy et al. (2021) reported unpublished Phengodidae
from the same deposit. Kusy et al. (2021) summarized and reviewed the published mo-
lecular dating analyses of the elaterid-lampyroid clade, and showed that median esti-
mates suggest the split of the Lampyridae, Phengodidae, and Rhagophthalmidae clade
in the mid-Cretaceous. However, an earlier date is also possible (Kusy et al. 2021).
Another important issue is the monophyly of Rhagophthalmidae. e group
was originally proposed only for Dioptoma, Ochotyra, and Rhagophthalmus (Olivier
1907, 1910), and later Pic (1937) added Mimoochotyra. is concept was adopted by
McDermott (1964, 1966). Crowson (1972) transferred some Asian genera (Cydistus,
Diplocladon, Falsophrixothrix) from Drilidae to Phengodidae, and these were later
added to Rhagophthalmidae together with Dodecatoma (Lawrence and Newton 1995).
Cydistus was later transferred to Phengodidae (Kundrata et al. 2019). e current
concept of Rhagophthalmidae consists of males which have exactly 12 antennomeres,
with antennomere III being longer than antennomere II, a telescopic abdomen that is
usually narrowed apically, and females which are more or less larva-like. However, the
monophyly of this group as currently dened has never been rigorously tested.
Several genera were included in molecular phylogenetic analyses, including
Bicladodrilus, Falsophrixothrix, Mimoochotyra, and Rhagophthalmus (incl. Ochotyra)
Robin Kundrata et al. / ZooKeys 1126: 55–130 (2022)
106
(Bocakova et al. 2007; Kundrata et al. 2014, 2019). ese genera always formed a
monophylum. However, it should be noted that at least the generic placements of
specimens identied as Bicladodrilus sp. from China and Mimoochotyra sp. from
Malaysia are dubious. As Bicladodrilus, Bicladum, and Diplocladon are similar in
general appearance and possess biabellate antennae, this generic complex is in need
of revision. While there are no described Bicladodrilus species in China, a species of
Diplocladon was recently described from Hong Kong (Yiu 2017). e single described
species of Mimoochotyra is known from Java (Pic 1937; Wittmer 1944).
In his unpublished PhD thesis, Jeng (2008) focused on systematics and
paedomorphosis (neoteny) in Lampyridae. He also included representatives of
the rhagophthalmid genera Dioptoma, Diplocladon, Dodecatoma, Falsophrixothrix,
Menghuoius, Monodrilus, and Rhagophthalmus (incl. Ochotyra) in his morphology-
based analyses. ese genera were monophyletic and sister to Phengodidae. In
another unpublished PhD thesis, Roza (2022) focused on phylogenetic relationships
of Phengodidae, and included Bicladodrilus, Dioptoma, Diplocladon, Dodecatoma,
Falsophrixothrix, Pseudothilmanus, and Rhagophthalmus in his morphology-based
analyses. ese genera formed a monophylum in all analyses performed. A phylogenomic
analysis including representatives (ideally type species) of all rhagophthalmid genera
would be a valuable assessment of the monophyly of the group.
Bioluminescence and paedomorphosis in Rhagophthalmidae
Within Coleoptera, bioluminescence can be found almost exclusively within
the so-called “elaterid-lampyroid clade”, including Elateridae, Lampyridae,
Phengodidae, Rhagophthalmidae, and Sinopyrophoridae, and probably the extinct
Cretophengodidae (Oba et al. 2011; Fallon et al. 2018; Bi et al. 2019; Li et al. 2021b;
Kusy et al. 2021; Powell et al. 2022). In Phengodidae, all known larvae and females
are bioluminescent, as are males of some species (Costa and Zaragoza-Caballero
2010). Bioluminescence is hypothesized for lineages in which larvae and females are
unknown (e.g., Cydistinae; Kundrata et al. 2019). All known larvae and females of
Rhagophthalmidae are bioluminescent. Both larvae and females were reported for
Diplocladon (in fact, it is probably Haplocladon; see Remarks under both genera),
Menghuoius, and Rhagophthalmus, whereas only females are known for Dioptoma
(Green 1913; Gahan 1925; Coblentz and Hughes 1926; Ridley 1934; Haneda 1950;
Raj 1957; Lloyd 1971, 1978; Wittmer and Ohba 1994; Ohba et al. 1996a; Kawashima
2000; Jeng 2008; Li and Liang 2008; Li et al. 2008a; Kawashima et al. 2010). Males of
at least some genera (e.g., Dioptoma and Rhagophthalmus) also emit light (Kawashima
et al. 2010). At least in some cases, however, there are doubts about the correct genus
identication of larvae or females. For example, Jeng (2008) suggested that the giant
larviform female from Yunnan, China, identied as Diplocladon by Li and Liang
(2008) is “likely of Menghuoius giganteus or the other related species described from
there” (Jeng 2008: 135). e correct identication of larviform females is, however,
very important for conclusions on the evolution of morphological modications
Annotated catalogue of Rhagophthalmidae Olivier, 1907 (Coleoptera, Elateroidea) 107
caused by paedomorphosis (e.g., Jeng 2008; Kawashima et al. 2010). is should be
possible by e.g., rearing both sexes of the same species from larvae, nding a mating
couple, or by the use of DNA barcoding. Information on the life-history and biology
of most genera of Rhagophthalmidae is minimal or entirely absent. Further research
should be conducted to conrm the presence of bioluminescence in the remaining
rhagophthalmid genera.
Elateroid beetles are well-known not only for bioluminescence but also for
morphological modications caused by paedomorphosis (Crowson 1972; Cicero
1988; Bocak et al. 2008; Ferreira and Ivie 2022). In Elateroidea, mainly adult females
are more or less modied, with a gradual series of morphological modications across
many families (Elateridae, Jurasaidae, Lampyridae, Lycidae, etc.), ranging from taxa
that possess only a slightly softer body cuticle and a more relaxed abdomen through
a number of intermediate stages, with variously reduced mouthparts, antennae,
elytra, hind wings, and/or parts of the thorax, and a higher number of free abdominal
ventrites, to taxa which are highly larviform (Bocakova et al. 2007; Bocak et al. 2008;
Ferreira et al. 2019, 2020, 2022; Kundrata and Bocak 2019; Rosa et al. 2020; Ferreira
and Ivie 2022). In both Phengodidae and Rhagophthalmidae, all known females are
highly paedomorphic, being wingless and larva-like (Costa and Zaragoza-Caballero
2010; Kawashima et al. 2010). In Rhagophthalmidae, females are known only for
Dioptoma, Diplocladon (Haplocladon?), Menghuoius, and Rhagophthalmus (Haneda
1950; Harvey 1952; Ohba 1997c; Kawashima 1998; Chen 2003; Jeng 2008; Li
and Liang 2008; Li et al. 2008a); however, only those of Diplocladon (Haplocladon?)
and Rhagophthalmus are described in detail (Kawashima et al. 2010). Interestingly,
females of both genera exhibit dierent degrees of paedomorphic modications, with
Diplocladon (Haplocladon?) being completely larviform (including having stemmata,
antennae with three antennomeres, tibiotarsus with a single pretarsal claw, and missing
ovipositor) and Rhagophthalmus being incompletely larviform (having compound eyes,
antennae with six or seven antennomeres, tarsi with ve tarsomeres and two pretarsal
claws, and ovipositor; Kawashima et al. 2010). Similar cases of dierent levels of
morphological modications in females of dierent genera were also reported for e.g.,
Elateridae (Drilus Olivier, 1790 being more paedomorphic than Omalisus Georoy,
1762 or Cebrio Olivier, 1790; Kundrata and Bocak 2019), Jurasaidae (Jurasai Rosa et
al., 2020 being more paedomorphic than Tujamita Rosa et al., 2020; Rosa et al. 2020),
and Lampyridae (Lamprigera Motschulsky, 1853 or Stenocladius Fairmaire, 1878 being
more paedomorphic than Lampyris Georoy, 1762 or Lamprohiza Motschulsky, 1853;
Ohba et al. 1997; Dong et al. 2021). It would be, therefore, very interesting to discover
and describe in detail the females of all remaining rhagophthalmid genera.
Generic classification and systematics of Rhagophthalmidae
It is clear from the above text that the classication and systematics of Rhagophthalmidae
is in a very poor state of knowledge. Species of Bicladodrilus, Bicladum, Falsophrixothrix,
Mimoochotyra, and Monodrilus have not been taxonomically treated since their
Robin Kundrata et al. / ZooKeys 1126: 55–130 (2022)
108
descriptions, and their names have usually appeared only in catalogues, if at all.
Taxonomic revisions are urgently needed for all genera currently included in
Rhagophthalmidae with the exception of Pseudothilmanus, which was revised recently
(Kundrata and Bocak 2011a). Although the most species-rich genus Rhagophthalmus
received some taxonomic attention in the last decades (e.g., Wittmer and Ohba 1994;
Wittmer 1997; Kawashima and Satô 2001; Kawashima and Sugaya 2003; Li et al.
2008a; Ho et al. 2012; Yiu 2017), a comprehensive revision is still needed.
Due to a scarcity of information on the morphology of most rhagophthalmid taxa,
an identication key which would help taxonomists to recognize genera and species
in collections and subsequently enhance knowledge on their diversity, variability,
and distributions, is also missing. Most importantly, it is necessary to delimit generic
boundaries in some problematic generic complexes. For example, Bicladodrilus, Bicladum,
and Diplocladon share biabellate antennae and relatively long elytra, and are not clearly
distinguished from one other. Detailed taxonomic studies should also be conducted to
revise the status of Ochotyra (currently a synonym of Rhagophthalmus) and Menghuoius
(currently a separate genus but treated by some authors as a synonym of Rhagophthalmus).
Some genera contain species which are probably not congeneric with their type species
(e.g., some Dodecatoma spp. resemble Pseudothilmanus more than D. bicolor), and e.g.,
Dodecatoma testaceiceps should be removed from Rhagophthalmidae after a detailed
revision. Taxonomic attention should be given not only to currently described taxa, but
also to numerous undescribed Rhagophthalmidae mainly from Southeast Asia, which
are housed in various institutional and personal collections (RK pers. obs.).
Taxonomic revisions are usually hampered by missing, lost, or otherwise unavail-
able type specimens, especially in long-neglected groups, such as Rhagophthalmi-
dae. However, the vast majority of name-bearing rhagophthalmid type specimens are
available in European and Asian museum collections. To date, we have been unable
to locate name-bearing type specimens of only ve species described by either Pic,
Fairmaire, or Olivier, four of which belong to Rhagophthalmus. Name-bearing type
specimens of species in 10 smaller genera are each deposited in one to three museum
collections only; however, those of Dodecatoma and Rhagophthalmus are in seven and
12 institutions, respectively.
Distribution of Rhagophthalmidae
Rhagophthalmidae are distributed in the Oriental realm and the Palaearctic bioregion
of East Asia, in the area from Afghanistan and Pakistan, through the Himalayas, Indian
Peninsula, Sri Lanka, China, and mainland Southeast Asia, to Sumatra, Java, Bali,
Borneo, and the Philippines. e center of genus-level diversity of Rhagophthalmidae
lies in Southeast Asia. Nine out of 12 genera have at least one species distributed
in Southeast Asia, with ve genera (i.e., Bicladodrilus, Bicladum, Falsophrixothrix,
Mimoochotyra, and Monodrilus) being endemic to the region. However, this only
accounts for approximately one third of described species. e genera Dodecatoma and
Pseudothilmanus are known only from the Himalayas and surrounding regions (one
Annotated catalogue of Rhagophthalmidae Olivier, 1907 (Coleoptera, Elateroidea) 109
species and one subspecies of Dodecatoma from Southeast Asia should be removed
from that genus), and Dioptoma is endemic to the Indian Peninsula and Sri Lanka.
Regarding the most species-rich genus Rhagophthalmus, only seven out of 34 species
are known from Southeast Asia, including only a single species from the Greater Sunda
Islands. Another seven species are known from the Indian Peninsula and Sri Lanka,
and the remaining majority of species are distributed in mainland China and among
the islands of East Asia.
Interestingly, in the eastern part of their distribution, Rhagophthalmidae have re-
mained within the boundaries of the Sunda Shelf and the Philippines, i.e, west of the
originally proposed Wallace Line, which was demarcated to separate Indo-Malayan
(Oriental) and Austro-Malayan (Australasian) realms (Wallace 1863; Voris 2000;
Lohman et al. 2011). e Sunda Shelf is a southward expansion of the continen-
tal shelf of Southeast Asia that was intermittently exposed by lowered sea levels dur-
ing the Pleistocene (Hall 1998; Voris 2000; Lomolino et al. 2017). e Wallace line
separates Bali and Borneo on the west from Lombok and Sulawesi on the east. It is a
strong dispersal barrier to many terrestrial animals because of deep oceanic trenches
(Lomolino et al. 2017). Rhagophthalmidae have a limited dispersal propensity due to
their highly modied larviform females and, therefore, it is not surprising that they
remained within the boundaries of the continental shelf of Southeast Asia, with a
single described species from the Philippines. Additionally, it should be noted that
there are no Rhagophthalmidae from east of the Wallace Line among the extensive
material of non-type specimens (including numerous new species) that reside in major
European museums and several personal collections, which the rst author examined
for a planned generic revision of the group. A single, unreported rhagophthalmid spe-
cies from Bali is the closest that the family has been observed to the Wallace Line. A
taxonomic revision of Rhagophthalmidae will further improve our knowledge of the
distributions of individual genera and their species, some of which are currently known
only from a single specimen.
Conclusions
Here we provide the rst comprehensive catalogue of the currently dened Rhagoph-
thalmidae. e only catalogues of the group were those of Olivier (1910) and McDer-
mott (1966; Rhagophthalminae as a subfamily of Lampyridae) but they contained only
three genera and nine species, and four genera and 21 species, respectively. Here, we
recognize 12 genera and 66 species. However, all genera but Pseudothilmanus urgently
need taxonomic revisions, and numerous new species await formal descriptions. e
phylogenetic position of Rhagophthalmidae as a sister group to Phengodidae is now gen-
erally accepted; however, interrelationships within the group and generic classication
remain poorly known. Although morphology-based analyses in two PhD studies that
were focused on related families (Jeng 2008; Roza 2022) conrm the monophyly of cur-
rently circumscribed Rhagophthalmidae, molecular analysis including representatives of
Robin Kundrata et al. / ZooKeys 1126: 55–130 (2022)
110
all genera would be desirable. Additionally, little information is known of the biology of
the group. Although various studies have been published on the ontogeny, biology, and
behaviour of the most common genus Rhagophthalmus, there is virtually nothing known
about the majority of other genera. Because known females in Rhagophthalmidae are
highly morphologically modied and remain larviform as adults, they are interesting
subjects for researching the evolution of paedomorphosis in Elateroidea. However, only
a few have been studied in detail (Kawashima et al. 2010). Additionally, all known larvae
and females (and some males) are bioluminescent, and therefore are an important source
of information for research on the evolution of bioluminescence in beetles. However,
this phenomenon is also understudied in Rhagophthalmidae, as larvae and females are
unknown for most genera. Discoveries, eld observations, morphological studies, and
correct genus and species identications of larvae and larviform females of Rhagoph-
thalmidae are therefore crucial not only for our improved knowledge of the diversity,
systematics, and morphology of the group, but also for a better understanding of the
evolution of paedomorphosis and bioluminescence in Elateroidea and beetles in general.

The Elateridae family (click beetles) represents a highly diverse lineage that possesses a specialized clicking mechanism to startle predators. At present, however, phylogenetic relationships, especially among recognized subfamilies, remain contentious. Mitochondrial genomes (mitogenomes) can help resolve previously intractable phylogenetic relationships using morphological or limited molecular data. Here, we report the complete mitogenome of Pectocera sp. (Elateridae: Dendrometrinae: Oxynopterini), which was 15,962 bp in length and showed a typical gene number and order as most beetle mitogenomes, including 13 protein-coding genes (PCGs), 22 transfer RNA genes, 2 ribosomal RNA genes, and 1 noncoding control region (AT-rich region). Comparative genomic analyses showed a high degree of feature similarity among Pectocera sp. and other click beetles. Evolutionary analysis of all PCGs based on the nonsynonymous/synonymous substitution rate ratio (ω) indicated that cox1 and atp8 exhibited the lowest and highest evolutionary rates, respectively, and that the evolutionary rates of all PCGs, except for cox3, nad2, and nad3, were lower than the average ω of click beetles. Phylogenetic analyses based on concatenated and coalescent approaches indicated that Pectocera sp. was sister to Campsosternus auratus in the same tribe (Oxynopterini) with high support. This study offers insight into the mitogenomic basis of Pectocera sp. and provides an important data resource for exploring the taxonomy, phylogeny, and evolution of click beetles.

Beetles constitute the most biodiverse animal order with over 380 000 described species and possibly several million more yet unnamed. Recent phylogenomic studies have arrived at considerably incongruent topologies and widely varying estimates of divergence dates for major beetle clades. Here, we use a dataset of 68 single-copy nuclear protein-coding (NPC) genes sampling 129 out of the 193 recognized extant families as well as the first comprehensive set of fully justified fossil calibrations to recover a refined timescale of beetle evolution. Using phylogenetic methods that counter the effects of compositional and rate heterogeneity, we recover a topology congruent with morphological studies, which we use, combined with other recent phylogenomic studies, to propose several formal changes in the classification of Coleoptera: Scirtiformia and Scirtoidea sensu nov., Clambiformia ser. nov. and Clamboidea sensu nov., Rhinorhipiformia ser. nov., Byrrhoidea sensu nov., Dryopoidea stat. res., Nosodendriformia ser. nov. and Staphyliniformia sensu nov., and Erotyloidea stat. nov., Nitiduloidea stat. nov. and Cucujoidea sensu nov., alongside changes below the superfamily level. Our divergence time analyses recovered a late Carboniferous origin of Coleoptera, a late Palaeozoic origin of all modern beetle suborders and a Triassic–Jurassic origin of most extant families, while fundamental divergences within beetle phylogeny did not coincide with the hypothesis of a Cretaceous Terrestrial Revolution.

We here report a new elateroid, Anoeuma lawrencei Li, Kundrata and Cai gen. et sp. nov., from mid-Cretaceous Burmese amber. Though superficially similar to some soft-bodied archostematans, Anoeuma could be firmly placed in the polyphagan superfamily Elateroidea based on the hind wing venation. Detailed morphological comparisons between extant elateroids and the Cretaceous fossils suggest that the unique character combination does not fit with confidence into any existing soft-bodied elateroid group, although some characters indicate possible relationships between Anoeuma and Omalisinae. Our discovery of this new lineage further demonstrates the past diversity and morphological disparity of soft-bodied elateroids.

We understand very little about the timing and origins of bioluminescence, particularly as a predator avoidance strategy. Understanding the timing of its origins, however, can help elucidate the evolution of this ecologically important signal. Using fireflies, a prevalent bioluminescent group where bioluminescence primarily functions as aposematic and sexual signals, we explore the origins of this signal in the context of their potential predators. Divergence time estimations were performed using genomic-scale datasets providing a robust estimate for the origin of firefly bioluminescence as both a terrestrial and as an aerial signal. Our results recover the origin of terrestrial beetle bioluminescence at 141.17 (122.63–161.17) Ma and firefly aerial bioluminescence at 133.18 (117.86–152.47) Ma using a large dataset focused on Lampyridae; and terrestrial bioluminescence at 148.03 (130.12–166.80) Ma, with the age of aerial bioluminescence at 104.97 (99.00–120.90) Ma using a complementary Elateroidea dataset. These ages pre-date the origins of all known extant aerial predators (i.e. bats and birds) and support much older terrestrial predators (assassin bugs, frogs, ground beetles, lizards, snakes, hunting spiders and harvestmen) as the drivers of terrestrial bioluminescence in beetles. These ages also support the hypothesis that sexual signalling was probably the original function of this signal in aerial fireflies.

Several firefly luciferases eliciting light emission in the yellow-green range of the spectrum and with distinct kinetic properties have been already cloned, sequenced, and characterized. Some of them are currently being applied as analytical reagents and reporter genes for bioimaging and biosensors, and more recently as potential color tuning indicators of intracellular pH and toxic metals. They were cloned from the subfamilies Lampyrinae (Photinini: Photinus pyralis, Macrolampis sp2; Cratomorphini: Cratomorphus distinctus), Photurinae (Photuris pennsylvanica), Luciolinae (Luciola cruciata, L. lateralis, L. mingrelica, L. italica, Hotaria parvula), and Amydetinae (Amydetes vivianii) occurring in different parts of the world. The largest number has been cloned from fireflies occurring in Brazilian biomes. Taking advantage of the large biodiversity of fireflies occurring in the Brazilian Atlantic rainforest, here we report the cloning and characterization of a novel luciferase cDNA from the Photurinae subfamily, Bicellonycha lividipennis, which is a very common firefly in marshlands in Brazil. As expected, multialignements and phylogenetic analysis show that this luciferase clusters with Photuris pennsylvanica adult isozyme, and with other adult lantern firefly luciferases, in reasonable agreement with traditional phylogenetic analysis. The luciferase elicits light emission in the yellow-green region, has kinetics properties similar to other adult lantern firefly luciferases, including pH- and metal sensitivities, but displays a lower sensitivity to nickel, which is suggested to be caused by the natural substitution of H310Y.

The Leptolycini are a group of Lycidae endemic to the West Indies. Leptolycini adult females have been hypothesized to be extreme paedomorphic (i.e., larviform), however, females and larvae of the group are currently unknown. Here we provide the first association of adult male and immature life stages from the Puerto Rico using DNA barcoding, also collections-based associations and descriptions of immature Leptolycini and the first description of a paedomorphic female from the Virgin Islands. To carry out these life-stage associations we prepared an in-depth review of the Leptolycini fauna of the Puerto Rican bank (Puerto Rico and Virgin Islands). Several new taxa and taxonomic arrangements are proposed: Cessator crypticusnew species, Cessator tortolensisnew species, Cessator obrienorumnew species; Dracolycus chupacabranew genus and species, Dracolycus marshallinew species; Leptolycus falsoheterocornisnew species, and Leptolycus viensisnew species. Nanolycus gnomus Kazantsev is moved to Cessator gnomus (Kazantsev) new combination, rendering Nanolycus Kazantsev a new junior synonym of Cessator Kazantsev. The subgenus Baholycus Bocak is a new junior synonym of Leptolycus Leng and Mutchler. Leptolycus heterocornis var. flavicollis Leng and Mutchler is elevated to Leptolycus flavicollis Leng and Mutchler new status; Leptolycus (Leptolycus) albicauda Kazantsev is a new junior synonym of Leptolycus flavicollis Leng and Mutchler. An updated key to the adults and immature forms of Leptolycini from the Puerto Rican bank and a discussion on the importance of scientific collections in biodiversity studies is also provided.

The subfamily Ototretinae represents an important and unusual lineage of fireflies. Here, we sequenced and annotated three mitogenomes for this subfamily, with two Stenocladius species and one Drilaster species as representatives. The mitogenome of Stenocladius exhibits a rearranged gene order between trnC and trnW caused by transposition, which is a novel finding in Lampyridae. Meanwhile, a long intergenic space (241 to 376 bp) exists between the two rearranged genes, and some remnants (23 bp) of trnW are present within this non-coding region. Moreover, phylogenetic analyses did not recover the monophyly of Ototretinae, in which Drilaster is shown at a basal lineage in Lampyridae, but Stenocladius seems more related to Luciolinae. Therefore, the gene rearrangement in Stenocladius is presumed to result from independent evolutionary events, suggesting that this genus should be placed in a separate lineage. Nevertheless, more representative mitogenomes from different groups are required to verify the present results.
