Sagrinae of Laos (Coleoptera: Chrysomelidae)
by Lukáš Sekerka & Michael Geiser
Abstract. Sagrinae species occurring in Laos are reviewed. For each species, a faunistic overview, new records
and additional taxonomic remarks are given where necessary. Sagra fulgida Weber, 1801 is recorded for the
first time from Laos. Sagra carbunculus Hope, 1842 is excluded from the Laotian fauna as a doubtful record.
In total five of nine Oriental species of Sagra are presently recorded from Laos. A key to all species of Sagra
occurring in the Oriental Region is given.
Key words. Entomology – taxonomy – identification key – Sagrinae – Chrysomelidae – Oriental Region –
Sagrinae, also known as kangaroo or frog-beetles, are a small subfamily of leaf
beetles (Chrysomelidae) with 67 species, mainly distributed in the Old World tropics
(MONRÓS 1958, KONSTANTINOV & SEKERKA 2010, SEKERKA & VOISIN 2014). The
subfamily is most diverse in Australia, where 11 genera and 33 species occur, most of
them endemic, except for the widespread S. femorata (Drury, 1773). The only genus
represented in the Oriental Region is Sagra Fabricius, 1792. Its species display great
intraspecific variability in colour and morphological characters, and as a result many
individual or geographic forms were described under different names (e.g. S. femorata
has about 40 synonyms). Over time, these taxa have been reduced to subspecies,
varieties or aberrations and as a result only nine species are currently recognised as valid
in the Oriental region (CHEN & PU1962, KONSTANTINOV & SEKERKA 2010, SEKERKA &
Although Asiatic Sagrinae were reviewed and keyed out several times (e.g. JACOBY
1908, KUNTZEN 1914, CHEN 1942, CROWSON 1946, GRESSITT & KIMOTO 1961, CHEN &
PU1962, KIMOTO & GRESSITT 1979), their distribution and biology remains rather poorly
known. MAULIK (1941) published an overview on their biology with description of
immature stages of S. femorata. Larvae are stem borers in various shrubs and woody
lianas, mainly of the plant family Fabaceae (MAULIK 1941, CHEN & PU1962). However,
Sagra are known to be associated also with several other plant families, such as
Convolvulaceae, Dioscoreaceae, Euphorbiaceae, Meliaceae, Rubiaceae, Rutaceae, and
Verbenaceae (MAULIK 1941). Unfortunately, Maulik did not usually specify whether a
host plant record applied to adults or larvae. Records of adults may just be incidental.
The first records of Sagrinae from Laos were published as late as the 1940s (CHEN
1942, CHEN & PU1962), and lacked precise locality data. The first precise data were
published by KIMOTO & GRESSITT (1979). This contribution is the first comprehensive
overview of the Laotian fauna, presently including five of the nine Asiatic Sagrinae
species, while the occurrence of two further species is possible. Also, we provide a key
to all species occurring in the Oriental Region. The species placed in square brackets
have not yet been recorded for Laos, but may possibly occur there.

Brief history of Laotian material
Land-locked Laos was for a long time one of the most inaccessible countries in
Asia, and only a few insect specimens were captured there before the 1920s. Early
specimens, labelled only “Laos”, were collected by Mouhot and purchased at Stevens’
Auctions in London by J. S. Baly. The largest collection until recent times was made by
René Vitalis de Salvaza, a French naturalist, who collected extensively in French
Indochina between 1913–1922. In his time travelling in Laos was difficult, and most
easily achieved by boat along the major rivers. Despite this fact, Vitalis also travelled
overland in northern Laos and was able to reach some remote inland localities,
particularly in today’s Louangnamtha province. His material was partly sold by Eugene
Le Moult and is spread among several collections. The bulk of his chrysomelids are now
preserved in the museums in Paris (mainly via Maurice Pic and René Oberthür
collections), London (individually purchased), Prague (via Julien Achard collection),
and Genoa (purchased by Gestro). Probably, many other museums and institutions also
hold some of Vitalis’ material, due to exchanges among museums and private collectors.
Much of his material in Paris and Prague is quite poorly labelled, even though Vitalis
seemed to have been rather precise in noting localities for his material, including dates
of collection. Unfortunately, some of his contemporaries did not value his locality data,
and many duplicate specimens were labelled rather poorly in their collections. This is
particularly true for Prague material which was mounted but has no precise locality data.
There must have been several boxes of Vitalis’ material when Achard’s collection
entered the museum in 1926. Part of the material was provided with the typical Le Moult
and Achard small labels with locality data but without date (material collected in 1918
and perhaps before). However, most specimens in Achard’s material came from the
expeditions after 1920 and when they were mounted, only the first specimen in the series
was provided with a locality label and the others ones only eventually with dates of
collection, if different from the first specimen. These labels were handwritten by Achard.
Unfortunately, nearly all specimens were later provided only with a general handwritten
label “Haut-Laos Vitalis” by Jan Bechynì and incorporated into the general collection,
thus the precise locality data were lost. Luckily in some specimens, Achard’s original
labels with collecting dates were preserved, so there is some possibility of tracing
localities based on these dates.
Perhaps also some specimens labelled “Tonkin” or “Indochina” may have
originated from present-day Laos, which used to be part of colonial French Indochina,
and some of its border areas may have been formerly assigned to Tonkin.
Later on, during the 1960s, J. A. Rondon collected extensively in Laos, partly with
the help of local collectors. His material was worked on by KIMOTO & GRESSITT (1979)
and is deposited in the Bernice P. Bishop Museum in Hawaii.
Until fairly recently, the fauna of Laos remained one of the most poorly known in
SE Asia. The country became more accessible to foreign visitors about 20 years ago,
which led to an increase in the number of entomological expeditions. Particularly
extensive material was assembled during the “Beetles of Laos” survey project organised
by the Basel Natural History Museum.

Sagrinae species recorded from Laos
[Sagra carbunculus Hope, 1842]
Published faunistic data. “Laos” (CHEN 1942).
Notes. CHEN (1942) published records from Laos and Cambodia of this species, among
others, without exact locality, which constitute the first records of S. carbunculus from
these countries. This was the only existing record for Laos and was repeated by CHEN &
PU(1962) and KIMOTO & GRESSITT (1979). Unfortunately, we had no opportunity to
verify Chen’s material and see whether he had mislabelled or misidentified specimens.
The latter could have easily been the case, since females of S. carbunculus are nearly
inseparable from those of S. fulgida. So far we have not seen any specimen of S.
carbunculus from former French Indochina and the species seems to be restricted to
mountain regions of NE India, Nepal, China and possibly also Myanmar. Its occurrence
in Laos requires confirmation based on recent specimens. Hence, the species is treated
here as only possibly occurring in Laos.
Sagra carbunculus is closest to S. fulgida and, like S. mouhoti, differs in male hind
femora lacking a preapical tooth. The latter differs from S. carbunculus in very coarsely
and densely punctate pronotum, appearing nearly dull and punctures touching each other
at least in apical third while S. carbunculus and S. fulgida have shiny and coarsely but
sparsely punctate pronotum. Females are quite difficult to distinguish, however, typical
populations of S. fulgida differ in much sparser and finer punctation of elytra while the
southern populations have a coarser elytral surface with impressed wrinkles. Also we
have not seen specimens of S. carbunculus that are completely metallic blue, which is a
very common coloration in S. fulgida.

Notes. A widespread and very polymorphic species in SE Asia. Individual forms and
populations were described as distinct nominal taxa. However, all were shown to be
products of intraspecific variability, connected by intermediate forms and often two or
more former “species” occur together on one plant and emerge from one gall. Sagra
femorata can be easily separated from other species by its finely punctate pronotum,
which appears impunctate at low magnifications.

Notes. Sagra fulgida is a widespread species in SE Asia and quite polymorphic.
Individual forms were described under several names, however, these were recently
synonymised with the nominal species (SEKERKA 2010, SEKERKA & VOISIN 2014).
Typical specimens (also described as S. leechi Jacoby, 1888; Fig. 4) have very smooth
and polished elytra with very fine and sparse punctation, and green or golden green
elytra. The form with blue elytra was described as subspecies janthina Chen, 1942,
however, except for colour there are no morphological differences from the
nominotypical taxon. The typical form and its colour aberrations occur in SE China. The
form distributed in Yunnan and former Indochina was described under the name minuta
Pic, 1930 (= insuturalis Pic, 1953, subalutacea Pic, 1953; see SEKERKA & VOISIN (2014)
for details; Fig. 3) and differs from the typical form in the irregular surface of the elytra
with impressed wrinkles and coarse punctation. It was treated as subspecies by CHEN &
PU(1962). However, the elytral structure of S. fulgida becomes gradually coarser from
E China (Fujian, Jiangxi, Zhejiang) to SE China (Guangdong, Guangxi, Guizhou, Hubei,
Sichuan) and, the populations from Yunnan southwards (= S. minuta) are the most
Laotian populations of Sagra fulgida can easily be separated from the other small-
sized Sagra species by the irregular and quite coarse surface sculpture of the elytra, with
small but distinct impressed wrinkles and punctures. Other species have elytra finely to
moderately punctate, but never with impressed wrinkles. The species is often
misidentified as S. odontopus, but the latter has an enlarged and horse-shoe shaped
mesosternal apex (small and round in S. fulgida) and metallic blue colour (all specimens
of S. fulgida we have seen from Laos had purple elytra). Specimens of S. mouhoti with
reduced sutural stripe have similar colour, but differ in having pronotum densely
punctate and dull while that of S. fulgida is shiny and sparsely punctate.
[Sagra humeralis Jacoby, 1904]
Notes. The species is known from China: Guizhou, Yunnan and Zhejiang (JACOBY 1904,
CHEN 1935). CHEN (1935) also added “Tonkin” (probably according to ACHARD 1913)
and this record was repeated by subsequent authors who interpreted the locality as
Entomologica Basiliensia et Collectionis Frey 35, 2016 449
northern Vietnam (CHEN & PU1962, KIMOTO & GRESSITT 1979). However, ACHARD
(1913) published a redescription of S. humeralis and noted it was described from “Mouy
Tsé (Tonkin)”. This locality is now situated in southern Yunnan, at that time part of the
French protectorate of Tonkin. Therefore Vietnam should be deleted from the species’
known range, as no known specimen originates from present-day Vietnam. On the other
hand it is quite likely that the species could be found in the mountains of Laos or
Vietnam, adjacent to the Chinese border, thus is included here as a possible candidate for
the Laotian fauna.
Sagra humeralis can be easily separated from others by its dull black body with
metallic purple spot on humeri. So far this species is only known from a few specimens.

Note. Sagra jansoni can be readily separated from other species with a coarsely punctate
pronotum by its elongate body, that is more than twice as long as wide.
Sagra mouhoti Baly, 1861
Published faunistic data. “Laos” (CHEN & PU1962); CHAMPASACK: Pakse, LOUANGNAMTHA: Muong
Sing (KIMOTO & GRESSITT 1979).
New faunistic data. XIENGKHUANG: “Xieng Khouang”, 13.v.1919, 1 spec., R. Vitalis de Salvaza lgt.
(BMNH); Ban Tha Chôk to Ban Na Sala, 19°32–35′N, 103°25–27′E, 930-1175 m, 2 spec., M. Geiser & D.
Hauck lgt. (NHMB, LSC).
Notes. KIMOTO & GRESSITT (1979) incorrectly listed the locality Muang Sing as being in
the Luangprabang province. It is situated in the Louangnamtha province.
This species has the most coarsely and densely punctate pronotum of all small
Asiatic Sagra species. The pronotum also appears dull, while in other species it is shiny
and sparsely punctate. Typical specimens of S. mouhoti have purple elytra with a broad,
blue sutural stripe, however, the stripe is sometimes reduced and such specimens are
often misidentified as southern populations of S. fulgida (= S. minuta). But the latter has
much sparser and finer punctation of the pronotum and hind tibia in males with a
preapical tooth that is absent in S. mouhoti.
[Sagra moghanii Chen et Pu, 1962]
Note. This species may be recorded from Laos in future, as it was described from
southern Yunnan (CHEN & PU1962). It is closest to S. odontopus, as both share enlarged
L. SEKERKA & M. GEISER
and horse-shoe shaped mesosternal apex. We have not seen any specimen of S. mohganii
but, according to the description, it differs in the structure of hind legs, as given in the

Notes. Sagra odontopus can be easily recognised by the enlarged and horse-shoe shaped
apex of the mesosternum as other similar Laotian species have the apex small, round and
normally convex. It has also uniformly metallic blue dorsum while Laotian populations
of S. fulgida have purple elytra.
KIMOTO & GRESSITT (1979) published numerous specimens of S. odontopus from
various localities across Laos. On the other hand they listed no records of S. fulgida,
what is curious since that species appears to be the more common of the two in Laos. It
would be desirable to re-examine the material they studied, to determine whether all
records truly refer to S. odontopus, which has often been confused with S. fulgida.
We would like thank Max Barclay (BMNH), the late Michel Brancucci (NHMB),
Jiøí Hájek (NMPC) and Pol Limbourg (IRSN) for the loan of material used in this study,
as well as Keita Matsumoto (BMNH) for taking habitus pictures of S. humeralis and the
type of S. leechi Also, we would like to thank Isabelle Zürcher and Matthias Borer for
providing access to recently arrived material at NHMB. Furthermore, we thank our
colleagues Max Barclay (BMNH) and Jan Bezdìk (Mendel University, Brno) for their
review and helpful suggestions. Study of type specimens and other additional material
housed in BMNH and Musée National d’Histoire Naturelle, Paris was supported by the
Synthesys grants nos. GB-TAF-3616 and FR-TAF-4937 of the European Union to L.
Sekerka. The work was partly financially supported by Ministry of Culture of the Czech
Republic (DKRVO 2015/14, National Museum, 00023272).
