The problems of subsequent typification in genus-group names and use of the Zoological Record: A study of selected post-1930 Diptera genus-group names without type species designations

Abstract

We list 117 genus-group names of Diptera that were proposed after 1930 with diagnoses and more than one included spe-cies but without type species designations and review their current status. Research into the earliest proposals making the names available resulted in one new synonymy: Breviculala Ito, 1949 = Pseudacidia Munro, 1935, n. syn. (Tephritidae), the discovery of a number of earlier designations, and the recognition of available genus-group names previously thought to be nomina nuda. Discussion is made concerning type designations in the Zoological Record and type fixations by monotypy for genus-group names proposed after 1930 without a type species designation.

Abstract
We list 117 genus-group names of Diptera that were proposed after 1930 with diagnoses and more than one included spe-
cies but without type species designations and review their current status. Research into the earliest proposals making the
names available resulted in one new synonymy: Breviculala Ito, 1949 = Pseudacidia Munro, 1935, n. syn. (Tephritidae),
the discovery of a number of earlier designations, and the recognition of available genus-group names previously thought
to be nomina nuda. Discussion is made concerning type designations in the Zoological Record and type fixations by
monotypy for genus-group names proposed after 1930 without a type species designation.
Key words: Diptera, nomenclature, genus-group names
Introduction
Scientific naming in zoology must adhere to a specific legislation for nomenclatural acts to be recognized as
“available” and “valid”. Non-compliant acts will have no nomenclatural standing. The legislative text — the
International Code of Zoological Nomenclature (I.C.Z.N., 1999) [hereinafter “the Code”] — has changed
over time, and new versions have in general not taken effect on acts proposed under (and compliant with)
older versions. While the various changes have been introduced to improve on zoological naming, they also
carry the risk of not being fully appreciated by the taxonomic community. The aim of the present paper is to
call attention to one such change that has been widely overlooked or misinterpreted, and to revise the Diptera
names that are affected. This paper is also a preliminary step in a collaborative project to check and verify the
over 22,000 genus-group names of Diptera currently in the Biosystematic Database of World Diptera [Even-
huis et al. (2008) at http://www.diptera.org] together with their type species, their status, and other relevant
details.
Genus-group names proposed after 1930
According to the Code, the method by which genus-group names of animals are made available differs dra-
matically between two primary criteria: whether the names were proposed before 1931 or after 1930.
1. Before 1931, a genus-group name could be proposed with a diagnosis or bibliographic reference to one;

EVENHUIS ET AL.

it could either have included species or not possess included species; and a type species designa-
tion in the original publication was not required. Instead it could have a type species designated at
a subsequent date (either by subsequent monotypy [the first and only included species] or by sub-
sequent designation [selected from one of the originally included species]).
2. After 1930, a genus-group name had to have both a diagnosis that is “purported to differentiate the
taxon” (or a bibliographic reference to one) AND a type species, fixed either by original designa-
tion or by monotypy. If it lacked either or both, it was to be treated as a nomen nudum (unavail-
able name).
[Additional to the requirements of those names proposed after 1930, names proposed after 1999 had to
be expressly proposed as new. No longer would the mere appearance of a new taxon in print serve to make a
name available. Currently there has to be in the original proposal of the name an indication that the name is
intended to be proposed as new.]
The fact that a genus-group name proposed after 1930 that did not have a type species designated for it
was a nomen nudum [= in essence the event of its original publication did not have nomenclatural relevance
(for only the genus-group name)] seemed to escape many taxonomists because they continued to designate
type species for these names subsequent to the original invalid publication and label these designations as
“subsequent designations” when in fact they were not.
According to the Code, those genus-group names that have a type species designated at a later date from
one of the originally included species do not bear the author and date of the original publication (the one with
the nomen nudum) referred to in the “subsequent designation”, but instead have both the authorship and the
date from that first fixation of the type species.
A further complication arises from the fact that many taxonomists seemed to believe that the only way to
make a post-1930 genus-group name available that was unavailable according to the Code for not having a
type species designation was to do so by explicitly designating a type. This is not always necessary as typifi-
cation can also occur by monotypy [not subsequent monotypy because that form of type fixation implies that
the name was available from the original publication but merely needed a type species fixation]. In the cases
of fixation by monotypy, the first time the genus-group name is mentioned with characters to differentiate it
(or bibliographic reference to such) and used in combination with a single valid species-group name subse-
quent to the nomen nudum publication and before 2000 [if published after 1999, the genus-group name must
have been expressly intended to be proposed as new] becomes the first appearance of the genus-group name
with all criteria for availability fulfilled and type species fixed by monotypy.
This apparently little-known fact of type fixation by monotypy seems to have slipped by many taxono-
mists, thus a thorough search of all usages of every post-1930 genus-group name originally published with a
diagnosis but without a type species designation is required to see if any subsequent usages of the name in
combination with a single valid name occur in the literature. Our research of Diptera genus-group names has
discovered eleven such cases for Diptera, most in the Zoological Record: Caenoconops Anonymous [Conopi-
dae], Ferneiella Cook [Scatopsidae], Lasiambia Anonymous [Chloropidae], Leptochironomus Lenz [Chi-
ronomidae], Parexoristina Anonymous [Tachinidae], Paroedesiella Anonymous [Chloropidae], Placantichir
Anonymous [Dolichopodidae], Pseudacidia Munro [Tephritidae], Stomacrypolus Anonymous [Agromyz-
idae], Turneria Parent [Dolichopodidae], and Zelindopsis Anonymous [Tachinidae].
The BDWD Project
The Biosystematic Database of World Diptera (BDWD) project was initiated to catalog every scientific name

DIPTERA GENUS-GROUP NAMES
in Diptera (family-group, genus-group, and species-group) and make that information available to the public
as a database and in other forms of publication. The family-group names (4,632) have been completed
(Sabrosky, 1999), the genus-group names (22,887) are in the verification process, and the species-group
names (193,974 [as of April 2008]) are 95% complete for data entry from primary and secondary sources.
During the verification process for the genus-group names, one of the tasks we undertook was to verify
all the names proposed after 1930 that were proposed without type species designations. This subset of genus-
group names was chosen for research because of the complicated rules governing them and in order to verify
the previous listings of them in the regional and world catalogs. By checking these names against published
catalogs and the original literature, we could verify and ensure accuracy of the data in the BDWD database
(Evenhuis et al., 2008). The BDWD database identified 117 genus-group names with the criteria of having
been published after 1930 with a diagnosis or bibliographic reference to one and having more than one
included species but with no type species designation. Most of these genus-group names were published later
with the same (or similar) spelling and authorship and had type species designated for them; others had the
authorship changed; and others were never published on again or were subsequently synonymized under a
nomenclaturally valid senior synonym.
The Zoological Record and post-1930 genus-group names
After conducting the research involved in checking the post-1930 Diptera genus-group names without type
species designations and finding subsequent actions making those names available, it became clear that the
Zoological Record has played a big part (in some cases possibly intentionally) in being the enabling medium
for making available the names previously thought to have been nomina nuda (see Table 1 below for exam-
ples).
The Zoological Record was initiated by a group of like-minded zoologists, mainly at the then British
Museum (Natural History), to assemble the zoological literature and index it, following on from Wiegmann’s
Archiv für Naturgeschichte, which had been doing the same thing but had large delays in publication and
some inadequacies that the Zoological Record team sought to overcome with their publication. The Zoologi-
cal Record began compiling the written record of zoological taxonomy for the year 1864 (published in 1865)
and has continued this task virtually unabated since then [see Bridson (1968) for a history of the first 100
years of the Zoological Record].
The significance of nomenclatural actions in the Zoological Record
It is an underlying assumption by zoologists that the compilers of the Zoological Record were/are neutral
parties merely “recording” what was printed by abstracting those publications and indexing the new taxa pub-
lished in them. As Neave (1939) pointed out in his editor’s preface to the Nomenclator Zoologicus, this was
not always the case. Specialists in various groups were added to the list of recorders early in its history to
assist with the enormous task of assembling the previous year’s literature and abstracting out the subjects and
new taxa proposed. In some cases, these specialists emended the original spellings of names that may have
corresponded better to “their” own methods of name formation. By doing so, they wittingly or unwittingly
added names to nomenclature. Some recorders also gave type species designations for genus-group names
that did not have them in their original publication. For those names otherwise validly proposed prior to 1931,
these then became subsequent designations (some are the earliest known for certain genera).
However, when the Code ruled that genus-group names after 1930 proposed without type species desig-
nations were to be treated as nomina nuda, those recorders that were designating types suddenly became not
just the author of a “subsequent designation” but the author of the genus-group name itself. This list of record-
ers as authors is compounded by those that listed only a single species-group name in association with a new

genus-group name. If the name was originally published with more than one originally included species and
there was no type designated, the action of the recorder in listing a single available species-group name in
association with the new genus-group name (which was made available in the Zoological Record by biblio-
graphic reference to the original publication of the characters used to differentiate it) thus fixed the name by
monotypy. The result of such action is that the name dates from and takes authorship from the action in the
Zoological Record. Authoring genus-group names was no doubt unintentional on the part of the recorder and
publishers of the Zoological Record, but there is unfortunately nothing in the Code to regulate whether or not
such type fixation (whether by monotypy or original designation) is required to be intentional.
Authorship in the Zoological Record
Actual authorship of nomenclatural actions in the Zoological Record is an interesting subject unto itself
and has been previously researched by Kerzhner (2003). From 1922–1945, the Insecta portion of the Zoologi-
cal Record was compiled by the Imperial Institute of Entomology. From 1946–1965, the Insecta portion was
compiled by the Commonwealth Institute of Entomology. After that, a combination of Commonwealth Insti-
tute of Entomology and Zoological Society of London staff, or just Zoological Society of London staff or
Zoological Record staff compiled the Insecta portions [see Kerzhner (2003) for a more detailed breakdown].
The glossary entry of the Code for “author (pl. authors)”, states:
“The person(s) to whom a work, a scientific name, or a nomenclatural act is attributed [Arts. 50, 51]
(see also anonymous). For the purposes of the Code, if a work is attributed to an editor, or an official
(e.g. Secretary), or a body (e.g. a committee or a commission), only that person(s) actually responsi-
ble for the work, name, or act, is deemed to be the author [Art. 50].”
Concerning “anonymous”, the glossary states:
“(1) Of a work: one that does not state the name(s) of the author(s). (2) Of a name or nomenclatural
act: one of which the authorship cannot be determined from the work itself [Art. 50.1]; see Article 14
for the availability of anonymous names or nomenclatural acts. (3) Of an author: one whose identity
cannot be determined from the work itself.”
Previous to the Record for 1922, the Insecta section of the Zoological Record was authored by one or
more persons listed on the title page and/or wrapper. Authorship of nomenclatural acts in that section are
attributed to the named author(s) of that section. However, from 1922–1945 the Imperial Institute of
Entomology was listed on the title page and/or wrapper of the Insecta section. Hall (1966) explained that S.A.
Neave was the responsible person for that section for the years 1922–1945 (published 1923–1946), but this is
evidence from an external source, which according to the Code cannot be used to determine authorship. Since
the person responsible for nomenclatural acts in the Insecta section of the Zoological Record from 1922
(published 1923) onwards cannot be determined from the work itself, each act must be attributed to
“Anonymous”. However, names and nomenclatural acts published after 1950 with “Anonymous” authorship
are invalid according to Article 14 of the Code, which, for the purposes of this study, means that all genus-
group names proposed after 1930 without type species designations and acted upon by typification published
in the Zoological Record after 1950 must thus be considered to remain nomina nuda.
Since the percentage of Diptera genus-group names dealt with here that were first made available in the
Zoological Record is fairly significant (11 out of 117 [ca. 10%]), notice is given here that taxonomists, bioin-
formatics workers, and nomenclaturalists should be aware of the nomenclatural actions regarding genus-
group names in this work and do a diligent search to record any possible actions that make available genus-
group names that may be the first or earlier than published elsewhere.

List of selected post-1930 Diptera genus-group names proposed without type species designations
The following is a list and the resulting nomenclatural and taxonomic status of 117 Diptera genus-group
names that were proposed after 1930 without fixation of a type species. Names that were proposed without a
diagnosis or bibliographic reference to one are not listed (whether they had included species or not). The
research involved in presenting this list has resulted in a number of corrections to previously published
accounts of these names in regional or world catalogs including authorship, date, page, and nomenclatural sta-
tus (Table 1).
Format
Each name is listed in the form of its original proposal and its status given. If a subsequent publication
occurred that fulfills the criteria for availability for this name, it is listed with the author, type species and
method of fixation. In addition, the family and current status (as listed in the BDWD) of the name are given.
Genus-group names listed in the headings in square brackets [ ] in plain Roman type are nomina nuda; those

Remarks. Hippa, Mattsson & Vilkamaa (2005b: 64) corrected the error in their original proposal of the name
(Hippa et al., 2005a) by designating Blagorrhina blagoderovi Hippa, Mattsson & Vilkamaa, 2005 as the
type species for Blagorrhina. However, the genus-group name is still a nomen nudum because they
failed to follow ICZN Code Article 16.1 and label the name as “new” in their 2005b paper.
[Bonessia]
Bonessia Mohrig, 1970: 142 (subgenus of Caenosciara Lengersdorf, 1941). Nomen nudum; genus-group
name proposed after 1930 without designation of type species from four included species.
Bonessia Anonymous in Staff of the Zoological Society of London, 1975: 707. Type species: Caenosciara
ignota Lengersdorf, 1941 (original designation). Nomen nudum; anonymous authorship after 1950.
Family: SCIARIDAE.
Current status: Nomen nudum; treated under Epidapus Haliday, 1851.
Remarks: Menzel & Mohrig (1998, 2000) indicated that because of the anonymous publication of the type
designation in the Zoological Record, the first type designation of the genus-group name should have the
authorship and date from Gerbachevskaja-Pavluchenko (1986: 38). However, there is no explicit desig-
nation made there; Gerbachevskaja-Pavluchenko (1986) merely indicated that the name was not made
available in 1975 in the Zoological Record and does not give any indication of a type species designa-
tion. Menzel & Mohrig (1998: 364) explicitly listed a type species (Caenosciara ignota Lengersdorf)
and gave a bibliographic reference to the original description of Bonessia, but the name remains a nomen
nudum because they treated the name in synonymy with Epidapus Haliday.
[Cachonopus]
Cachonopus Vaillant, 1953: 277. Nomen nudum; genus-group name proposed after 1930 without type desig-
nation from two included species.
Family: DOLICHOPODIDAE.
Current status: Nomen nudum; incertae sedis in Dolichopodidae.
Remarks: Vaillant (1953) proposed Cachonopus based on two newly described species (C. aereus Vaillant
and C. limosorum Vaillant) without designating a type. Negrobov (1991) listed both species (incorrectly
giving “Conchopus” as the original genus for limosorum) but failed to list the genus-group name. Yang
et al. (2006) apparently did not examine the original description and simply repeated Negrobov’s errors
in their world catalog. Cachonopus aereus is currently treated in the genus Chrysotimus Loew, 1857; C.
limosorum is currently treated in the genus
Micromorphus Mik, 1878. Negrobov et al. (2007) realized
that Cachonopus did not have a type species and designated one (C. limosorum), placed the genus in
synonymy with Micromorphus, and ironically claimed that it was Yang et al. (2006) who had made a
“misprint” in treating limosorum as originally in “Conchopus”! However, because Negrobov et al.
(2007) treated Cachonopus as a junior synonym and failed to denote the genus Cachonopus as “new”
(required by ICZN Article 16.1), Cachonopus remains a nomen nudum.
Caenoconops Anonymous
Caenoconops Kröber, 1939: 373. Nomen nudum; genus-group name proposed after 1930 without designation
of type species from two included species.

Caenoconops Anonymous in Imperial Institute of Entomology, 1940: 365. Type species: Caenoconops subap-

Family: CONOPIDAE.
Current status: Caenoconops Anonymous in Imperial Institute of Entomology, 1940.
Remarks: Kröber (1939) proposed Caenoconops based on two included species but failed to designate a type.
By recording Caenoconops with bibliographic reference to Kröber (1939: 373) and listing a single
species (Caenoconops subapicalis Kröber, 1939), the genus-group name fulfills the criteria for being
made available with its type species designated by monotypy in Anonymous in Imperial Institute of
Entomology (1940). Smith (1980), unaware of this valid proposal of the genus-group name, designated
Conops rhodesiensis Brunetti, 1925 as the type species but this is a later nomenclatural action.

Cryptocladopelma Townes
Cryptocladopelma Lenz, 1941: 37 (subgenus of Cryptochironomus Kieffer, 1918). Nomen nudum; genus-
group name proposed after 1930 without designation of type species from two included species.
Cryptocladopelma Townes, 1945: 153. Type species: Chironomus lateralis Goetghebuer, 1934 (original des-
ignation). Genus-group name proposed in synonymy but made available from being used as a valid name
by Lenz (1960).
Family: CHIRONOMIDAE.
Current status: Name available from Townes (1945); junior synonym of Cladopelma Kieffer, 1921.
Remarks: Article 11.6.1 is here considered to confer availability on Cryptocladopelma Townes, 1945. We are
aware that some ambiguity may emerge from the wording “A name which when first published”, insofar
as it matters whether or not Cryptocladopelma Lenz, 1941 is considered the same name as Cryptocla-
dopelma Townes, 1945. If it is considered the same name, it was not first published in synonymy and its
availability is not regulated by this Article. We think that even if Townes (1945) explicitly referred to
Lenz (1941) when listing Cryptocladopelma, these occurrences of the same word cannot be considered
to refer to the same name in the sense of the Code. In the present context, “A name” refers to a scientific
name, which according to the Code Glossary always is “Of a taxon”. Because Cryptocladopelma Lenz,
1941 does not have a type species indicated while Cryptocladopelma Townes, 1945 does, there is no way
the two taxa can be argued to objectively be “the same”.

Remarks
: The remark in Ashe (1983) that the name is technically a nomen nudum is erroneous. As correctly
mentioned by Spies & Reiss (1996: 69, 88), the treatment of the genus-group name in Beck & Beck

[Endotendipes]

Endotendipes Anonymous in Commonwealth Institute of Entomology, 1957: 449. Type species: Tendipes
abranchius Kieffer, 1913 (monotypy). Nomen nudum; anonymous authorship after 1950.
Family: CHIRONOMIDAE.
Current status: Nomen nudum; incertae sedis in Chironomidae: Chironominae: Chironomini.
Remarks: Tendipes abranchius Kieffer, 1913 was treated as a nomen dubium in Endochironomus by Ashe &
Cranston (1990). However, Spies & Saether (2004) cautioned use of this species in association with any
genus until a revisionary study of Endochironomus is done. Grodhaus (1987) had placed Tendipes
abranchius [sensu Lenz (1955), but not (necessarily) sensu Kieffer (1913)] in his new genus
Synendotendipes, but Spies & Saether (2004) argued that placement of it in Tribelos Townes, 1945 might
be just as likely. Until a revisionary study of Endochironomus s. lato can be completed, we treat the
genus-group name Endotendipes as
incertae sedis.

or three included species (1960).
Exoristella Herting, 1984: 6 (subgenus of Exorista Meigen, 1803). Type species: Tachina glossatorum Ron-

Family: TACHINIDAE.
Current status: Exoristella Herting, 1984 (subgenus of Exorista Meigen, 1803).
Remarks: Herting’s (1984) listing of Exoristella was essentially giving the information from Mesnil (1947)
and adding that one of Mesnil’s originally included species (Tachina delicatula Robineau-Desvoidy,
1863) was misidentified by Mesnil and is actually Tachina glossatorum Rondani, 1859. The latter was
the species selected by Herting (1984) as the type species for his Exoristella.

Ferneiella Cook
Ferneiella Cook, 1974: 87. Nomen nudum; genus-group name proposed after 1930 without designation of

Ferneiella Cook, 1977: 451. Type species: Ferneiella angusta Cook, 1977 (monotypy).
Family: SCATOPSIDAE.
Current status: Ferneiella Cook, 1977.
Remarks: Cook’s (1974) description of the genus was based on three species, of which only two from Europe
were described (a third from Australia was to be described later). Because no type species was desig-
nated in the 1974 work, that genus-group name is a nomen nudum. The first valid publication of the
name is from the generic characters and single described species from Australia in Cook (1977). The
type is by monotypy as no other species are referred to in the work. Cook in Freeman (1985: 42) and one
year later Krivosheina & Haenni (1986: 305) each formally designated Scatopse incompleta Verrall,
1886 as the type species, but the usage in Cook (1977) satisfies the rules of nomenclature and the type by
monotypy is the earliest available occurrence of the name.

Remarks: The designation of Metriocnemus subnudus Edwards as type species by Goetghebuer (1940) was

Remarks: Hennig (1934: 97) spelled the name as “Hemicheta” but since it is a nomen nudum there, the name
takes the spelling, authorship, and date from the proposal of the name in Steyskal (1968), who gave a
type designation and bibliographic reference to Hennig (1934: 97) for generic characters, thereby fulfill-
ing the criteria for availability.

Leptochironomus Lenz
Leptochironomus Pagast, 1931: 210 (subgenus of Chironomus Meigen, 1803). Nomen nudum; genus-group
name proposed after 1930 without designation of type species from two included species.
Leptochironomus Lenz, 1941: 32 (“Larven-Puppen-Typus” of the “Gruppe” Parachironomus Lenz, 1921 of
the subgenus Cryptochironomus Kieffer, 1918). Type species: Chironomus tener Kieffer, 1918 (mono-
typy).
Family: CHIRONOMIDAE.
Current status: Name available from Lenz (1941); junior synonym of Microchironomus Kieffer, 1918.
Remarks: Lenz (1941: 32) listed Leptochironomus [with bibliographic reference to characters in Pagast
(1931: 210)] and included only one species [Chironomus tener Kieffer (with Chironomus balticus
Pagast, 1931 in synonymy)]. Thus, this listing satisfies the Code to make the genus-group name avail-
able with the type species designated by monotypy. The availability of the genus-group name, even
though proposed as a subsection of a group of a subgenus, is allowed under Article 10.4 of the Code.
Townes (1945: 152) explicitly designated Chironomus balticus as the type species, but he treated the
name in synonymy. In contrast, Lenz’s (1941) treatment is earlier and makes the name available from
this publication and date.

Current status: Nomen nudum; incertae sedis in Chironomidae.
Remarks: Brundin (1964) gave characters purported to differentiate the genus-group taxon Ljungneria as
well as characters making two included new species-group names available (L. maorii and L. patagon-
ica), but he failed to designate a type species. Ashe (1983) and Spies & Reiss (1996) recorded the genus-

Remarks: Evenhuis (1994) treated this as an available and valid genus-group name thinking that the name
was made available by the type designation by Vevers and bibliographic reference to the original
description in the Zoological Record. Since the authorship of the Insecta section of the Zoological
Record for that year was “the Staff of the Zoological Record” and no specific person or persons can be
found from that work that were explicitly responsible for the nomenclatural act, the authorship must be
anonymous, which relegates the name to nomen nudum status.

Family: TACHINIDAE.
Current status: Name available from Anonymous in Imperial Institute of Entomology (1937); junior syn-

Remarks: The action in Imperial Institute of Entomology (1937: 385) with bibliographic reference to Ender-
lein (1936a) and the inclusion of a single species (Tachina affinis) makes the name available with type
species by monotypy. Herting (1984), unaware of the action in Imperial Institute of Entomology (1937),
explicitly designated Tachina affinis as the type species but kept the name in synonymy, thus the name
was a nomen nudum there.

Institute of Entomology’s (1937: 394) recording of the name with bibliographic reference to Enderlein
(1936a: 187) and listing of only one available species-group name makes the name available (type fixa-

Current status: Name available from Anonymous in Imperial Institute of Entomology (1937); junior syn-

Remarks: Enderlein (1936a: 114) proposed Placantichir based on two included species (one listed in the key
[P. nervosus Lehmann] and one in the figure caption [Placantichir wiedemanni (Fallén)]).The Imperial
Institute of Entomology (1937: 381) recorded the genus-group name giving bibliographic reference to
Enderlein (1936a: 114) and listed only one species (nervosus), thus the name is made available there
with type species by monotypy. Bickel (1994), unaware that Imperial Institute of Entomology (1937)
had made the name available, proposed the genus by bibliographic reference to Enderlein (1936a: 114)
and explicitly designated Dolichopus nervosus as the type species. However, by proposing the name in
synonymy after 1960, Bickel’s name is a nomen nudum.

Remarks: Jacentkovský (1941a: 31) is the first occurrence of the genus-group name Polleniomyia, but it
appeared with neither a diagnosis nor a type species indication. The name Polleniomyma Jacentkovský
(1944: 119) is an unnecessary replacement name for Polleniomyia as the latter is different by one letter

Current status: Pseudacidia Munro, 1935.
Remarks: Shiraki (1933: 216) proposed the genus-group name Pseudacidia for nine available species-group
names but failed to designate a type species, thus Pseudacidia Shiraki, 1933 is a nomen nudum. The first
to make the name available was Munro (1935: 256), who gave characters to distinguish the genus-group
taxon (in addition to a bibliographic reference to Shiraki, 1933: 216) and also provided a single species
name in association with it (hemileoides Munro, 1935), thus fixing the name by monotypy. A later desig-
nation by Hardy (1977) of Pseudacidia issikii Shiraki, 1933 put the name in synonymy with Acidiella
Hendel, 1914, the concept of which has been used until now. The type species of Pseudacidia Munro
(hemileoides Munro) is currently treated in Breviculala Ito, 1984 (e.g., Norrbom et al., 1999: 107), thus
by priority Pseudacidia Munro becomes a senior synonym of it [Breviculala Ito, 1949 = Pseudacidia
Munro, 1935, n. syn.] and the valid name to use for this group of species.

Psectrocladius curtistylus Goetghebuer, 1921 (original designation).
Family: CHIRONOMIDAE.
Current status: Pseudorthocladius Goetghebuer, 1943.
Remarks: By strict priority, the genus name would have been available from Edwards (1932: 141), who des-
ignated Spaniotoma flexuella Edwards as the type species. Cranston (1975) and Spies & Saether (2004)
detailed the confusing history of this genus-group name and its two type species designations and noted
that, since most recent authors had been using Pseudorthocladius sensu Goetghebuer (1943), reverting
to Edwards’s (1932) use would upset the nomenclatural stability of Pseudorthocladius and two other
genus-group names. The ICZN (2007) has ruled to conserve Pseudorthocladius Goetghebuer, 1943.

Remarks: Ashe’s (1983) comment that the name was still a nomen nudum was erroneous. The treatment by

Current status: Rainieriella Aczél, 1949 (subgenus of Rainieria Rondani, 1843).
Remarks: Whether species are explicitly included in the genus-group name Rainieriella in Hennig (1935b) is
equivocal. There are three species listed below the subgeneric heading but they lack the subgeneric name
in each species heading as was done for other species-group names attributed to subgenera within Rain-
ieria by Hennig (1935b). We treat the three listed there as included species. This is irrelevant as far as
nomenclature is concerned as the name in Hennig (1935b) is a nomen nudum. Aczél’s (1949) actions sat-
isfy the rules of nomenclature there and provide the first proposal of the genus-group name and its type
species fulfilling all requirements for availability.

[Tonnoirina]
Tonnoirina Schmitz, 1939: 88 (subgenus of Triphleba Rondani, 1856). Nomen nudum; genus-group name pro-
posed after 1930 without designation of type species from three included species. [Preoccupied by
Edwards, 1929.]
Tonnoirina Schmitz, 1941: 128. Type species: Triphleba rufithorax Schmitz, 1939 (original designation).
Nomen nudum; genus-group name proposed in synonymy and not made available from being used as a
valid name before 1961. [Preoccupied by Edwards, 1929.]
Family: PHORIDAE.
Current status: Nomen nudum; treated under Triphleba Rondani, 1856.
Remarks: The type designation in Schmitz (1941: 128) is explicit, but the treatment of Tonnoirina as a valid
name could be considered equivocal. Schmitz gives characters to differentiate it, but refrains from nam-
ing a replacement name for it as he says he finds it impractical to split Triphleba into subgenera. We con-
sider the refusal to consider subgenera of Triphleba as a statement of synonymy for Tonnoirina and treat
the name as such here.
[Trichotomesa]
Trichotomesa Hrabe, 1940: 20. Nomen nudum; genus-group name proposed after 1930 without designation of
type species from two included species.
Trichotomesa Pagast, 1947: 451. Type species: Syndiamesa nivosa Goetghebuer, 1928 (original designation).
Nomen nudum; genus
-group name proposed in synonymy after 1930 and not made available from being

used as a valid name before 1961.
Family: CHIRONOMIDAE.
Current status: Nomen nudum; treated under Pseudodiamesa Goetghebuer, 1939.
Remarks: Ashe (1983) indicated that no generic diagnosis was given for the genus-group name in Hrabe
(1940); however, there are larval physiological characters given for Trichotomesa on page 23. The
authorship is given as Pagast in Hrabe by Ashe (1983) and Ashe & Cranston (1990). There is nothing in
Hrabe (1940) to indicate that Pagast provided anything more than the name in that work, thus the author-
ship of the nomen nudum is attributed here to Hrabe.
Triopisopa Enderlein
Triopisopa Enderlein, 1936a: 179. Nomen nudum; genus-group name proposed after 1930 without designa-
tion of type species from three included species.
Triopisopa Enderlein, 1936b: 42. Type species: Agromyza simplex Loew, 1869 (original designation).
Family: AGROMYZIDAE.
Current status: Name available from Enderlein (1936b); junior synonym of Ophiomyia Braschnikov, 1897.
[Tristichothyrsus]
Tristichothyrsus Enderlein, 1936a: 118. Nomen nudum; genus-group name proposed after 1930 without desig-
nation of type species from two included species.
Family: PHORIDAE.
Current status: Nomen nudum; treated under Stichillus Enderlein, 1924.
Turneria Parent
Turneria Parent, 1934: 127. Nomen nudum; genus-group name proposed after 1930 without designation of
type species from two included species. [Preoccupied by Forel, 1885.]
Turneria Parent, 1935: 123. Type species: Turneria depressa Parent, 1935 (monotypy). [Preoccupied by Forel,
1885.]
Family: DOLICHOPODIDAE.
Current status: Name available from Parent (1935) but preoccupied; junior synonym and valid name is Nur-
teria Dyte & Smith, 1980.
Remarks: Parent (1934) described Turneria based on two available species-group names but failed to desig-
nate a type, thus the genus-group name is a nomen nudum in that publication. Dyte & Smith (1980) noted
that the name was preoccupied by Forel, 1885 and proposed a new genus Nurteria by designating one of
Parent’s originally included species and giving a bibliographic reference to the original description of
Turneria in Parent (1934) to make it available. They apparently missed the nomenclatural significance of
the use of the generic name in Parent (1935) where only a single species-group name is mentioned and
characters are also given (Parent, 1935: 124) to make the genus-group name available as well, thus the
name is no longer a nomen nudum but is still preoccupied by Forel, 1885. Nurteria is thus the valid
genus-group name for the species.

Uresipedilum Oyewo & Saether
Uresipedilum Sasa & Kikuchi, 1995: 40, 119 (subgenus of Polypedilum Kieffer, 1912). Nomen nudum; genus-
group name proposed after 1930 without designation of type species from nine included species.
Uresipedilum Oyewo & Saether, 1998: 317 (subgenus of Polypedilum Kieffer, 1912). Type species: Chirono-
mus convictus Walker, 1856 (original designation).
Family: CHIRONOMIDAE.
Current status: Uresipedilum Oyewo & Saether, 1998 (subgenus of Polypedilum Kieffer, 1912).
Zelindopsis Anonymous
Zelindopsis Villeneuve, 1943: 101. Nomen nudum; genus-group name proposed after 1930 without designa-
tion of type species from three included species.
Zelindopsis Anonymous in Imperial Institute of Entomology, 1946: 208. Type species: Zelindopsis duplaria
Villeneuve, 1943 (monotypy).
Family: TACHINIDAE.
Current status: Zelindopsis Anonymous in Imperial Institute of Entomology, 1946.
Remarks: Verbeke (1962: 168) explicitly designated Zenilla illita Villeneuve, 1916 as type species, but the
Imperial Institute of Entomology’s (1946: 208) record of the genus-group name with bibliographic refer-
ence to Villeneuve (1943: 101) and listing of only one available species-group name makes it available
from there, with type species by monotypy, and is earlier. Although the Imperial Institute of Entomol-
ogy’s (1946) designation is of a different species than designated by Verbeke (1962), there is no change
in generic concept because both species are currently treated in Zelindopsis.
