The taxonomic identity of the palaeonemertean Cephalothrix linearis (Rathke, 1799) has been obscure for nearly two centuries, because its original description applies to almost any congeners, including Cephalothrix filiformis (Johnston 1828) and Cephalothrix rufifrons (Johnston, 1837), which occur commonly in the North Sea and adjacent waters. In this paper, I redescribe C. linearis based on two topotypes from Bergen, one herein designated as the neotype for C. linearis, because Rathke’s original material is not extant; I invoke Article 70.3.2 of the International Code of Zoological Nomenclature to fix Planaria linearis Rathke, 1799 as the type species of Cephalothrix Örsted, 1843 for the sake of stability. From the neotype, I determined sequences of the 28S rRNA, 16S rRNA, and cytochrome c oxidase subunit I (COI) genes. Using the COI sequence, I inferred the phylogenetic position of C. linearis along with 316 cephalotrichid sequences currently available in public databases. A tree-based species delimitation analysis detected 43 entities among them, with 34 in Cephalothrix and nine in eitherBalionemertes or Cephalotrichella. I apply valid species names to 12 of the 34 entities in Cephalothrix. I tabulated a total of 36 nominal species that are likely the members of the genus; the following five were excluded even though their specific names were originally combined with Cephalothrix: Cephalothrix armata Ulyanin, 1870 [Monostilifera, possibly Emplectonema gracile (Johnston, 1837)], Cephalothrix fragilis Bürger, 1892 [now Cephalotrichella signata (Hubrecht, 1879)], Cephalothrix signata Hubrecht, 1879 [now in Cephalotrichella], Cephalothrix unipunctata Parfitt, 1867 [now Tetrastemma melanocephalum (Johnston, 1837) (Monostilifera)], and Cephalothrix viridis Chapuis, 1886 [possibly Heteronemertea]. The five names cephalothrix Diesing, 1850 (as Borlasia cephalothrix), kroyeri Diesing, 1850 (as Cephalothrix kroyeri), linearis Diesing, 1850 (as Borlasia linearis), lineata Claparède, 1862 (as Cephalothrix lineata), and oerstedii Diesing, 1850 (as Cephalothrix oerstedii) aredeclared nomenclaturally unavailable.

AbstractHarminius castaneus Fairmaire was described as a Eucnemidae, but all subsequent authors placed it among the Elateridae, usually as a valid genus and species near Athous. Neither the original description nor the illustration bear any resemblance to the species currently called castaneus. No original material could be found, therefore it is questionable as to what species Fairmaire described. To conserve nomenclatorial stability, application is being made to the International Commission on Zoological Nomenclature to set aside any previous type-species designation and to designate spiniger Candèze as the type-species of Harminius and Pseudocorymbites. Consequently, castaneus is considered as a species incertae dubia. An attempt is made to straighten out the usage of the names castaneus auct., spiniger Candèze, and florentinus Desbrochers. Previously castaneus auct has referred either to spiniger or florentinus (mostly to spiniger), whereas both are now recognized as valid species in the subgenus Harminius; gigas Reitter also belongs in the same subgenus. Pseudocorymbites Fiori is isogenotypic with Harminius and the subgenera Diacanthous Reitter and Megathous Reitter remain valid under Harminius, as in most catalogues.

Abstract The type species of Trophomera, T. iturupiensis, is redescribed from type material and important errors in the original description corrected. As a result of this emended description, Benthimermis is proposed as a junior synonym of Trophomera and its species transferred accordingly. The family name Benthimermithidae is retained according to articles 23.1 and 40.1 of the International Code of Zoological Nomenclature. Trophomera is diagnosed and an annotated list of nominal species presented. Trophomera litoralis sp. n., collected from the tidal zone of Ushishir Island (Kuril Archipelago), is described on the basis of four males. The males of T. litoralis sp. n. differ from those of other Trophomera species primarily by the much higher number of precloacal supplementary organs (105-108 vs 2-68). Trophomera litoralis sp. n. is most similar to T. regalis comb. n. yet differs by shorter body length (5.8-9.3 vs 14.9 mm), body proportions (a = 67-107 vs 124.4; c = 61-97 vs 135.7), greater length of the intermediate spermatoduct between the anterior and posterior testes (ca 1/7th vs ca 1/140th of body length), tail shape (rounded conoid vs pointed conoid), and number of precloacal supplementary organs (105-108 vs 49).

BackgroundProphocaandLeptophocarepresent the oldest known genera of phocine seals, dating from the latest early to middle Miocene. Originally,Prophoca rousseauiandProphoca proximawere described based on fragmentary remains from the Miocene of Belgium. However, several researchers contested the union ofProphoca rousseauiandProphoca proximainto one genus, without providing evidence. The stratigraphic context ofProphocaremained poorly constrained due to the lack of precise data associated with the original specimens collected in the area of Antwerp (north of Belgium).MethodsProphocaandLeptophocaare redescribed and their phylogenetic position among Phocidae is reassessed using PAUP. Dinoflagellate biostratigraphy has been carried out on sediment samples associated with specimens fromProphocaandLeptophocato elucidate their approximate ages.ResultsWhereas the speciesProphoca rousseauiis redescribed,Prophoca proximais considered synonymous toLeptophoca lenis, with the proposal of a new combinationLeptophoca proxima(Van Beneden, 1877). Sediment samples from specimens of both taxa have been dated to the late Langhian–early Serravallian (middle Miocene). Following a reinvestigation ofLeptophoca amphiatlantica, characters from the original diagnosis are questioned and the specimens ofLeptophoca amphiatlanticaare consideredLeptophocacf.L. proxima. In a phylogenetic analysis,Prophoca rousseauiandLeptophoca proximaconstitute early branching stem-phocines.DiscussionLeptophoca proximafrom the North Sea Basin is younger than the oldest known find ofLeptophoca proximafrom North America, which does not contradict the hypothesis that Phocinae originated along the east coast of North America during the late early Miocene, followed by dispersal to Europe shortly after. Morphological features of the appendicular skeleton indicate thatProphoca rousseauiandLeptophoca proximahave archaic locomotory modes, retaining a more prominent use of the fore flipper for aquatic propulsion than extant Phocidae.

Gall Induction

Cynipidae (Hymenoptera: Cynipoidea) is a diverse group of wasps, many of which are capable of inducing plants to make novel structures, galls, that protect and nourish the wasps' larvae. Other cynipids, especially those species in Ceroptresini and Synergini, are understood to be usurpers of galls made by other cynipids. The North American cynipid fauna has not been fully cataloged since 1979, but there is renewed interest in revising the taxonomy and in doing research that sheds light on the mechanisms of gall induction, the evolution of this life history, and their ecological interactions more broadly. Significant taxonomic changes have impacted the group since 1979, thereby warranting a new catalog. The current state of knowledge of species classified in Aulacideini, Ceroptresini, Diastrophini, Diplolepidini, Phanacidini, and Synergini in the United States, Canada, and Mexico is summarized in catalog format. We report 323 names, including 170 valid species of rose gall wasps, herb gall wasps, and inquiline gall wasps, classified in 12 genera, from the United States, Canada, and Mexico. Current taxonomic status, distribution, host associations, and vernacular names are listed for each species. The catalog also includes the original description of galls for many species of gall-inducer, as well as atomized characterizations of different gall traits as key-value pairs. For most galling species without existing vernacular names, new vernacular names are proposed.

It has been pointed out that there is an error in our recent paper (Rentz et al., 2012). On p. 24 we designated Miniagraecia viridis Rentz, Su, Ueshima sp. nov. as the type species of  the new genus Miniagraecia. However there is no such species.  There was a manuscript change in the name of the species and we did not catch it in the type species designation.  Miniagraecia is therefore a nomen nudum. Miniagraecia viridis is not a nominal species and Miniagraecia does not now have a fixed type species (International Code of Zoological Nomenclature, Article 67.1).

A checklist of Recent and fossil catfishes (Order Siluriformes) is presented, summarizing taxonomic literature published through 2005. From 4624 nominal species group names and 810 genus group names, 3093 species are recognized as valid, and are distributed among 478 genera and 36 families. Distributional summaries are provided for each species, and nomenclatural synonymies, including relevant information on all name-bearing types, are included for all taxa. One new name is proposed herein: Clariallabes teugelsi, as a replacement for Clarias (Allabenchelys) dumerili longibarbis David & Poll, 1937, which is preoccupied by Clarias longibarbis Worthington, 1933, but has been treated as a valid species of Clariallabes by Teugels. Acrochordonichthys melanogaster Bleeker, 1854, is designated as type species of Acrochordonichthys Bleeker, 1857, inasmuch as no earlier valid designation has been found. A new genus Pseudobagarius, is proposed for the “pseudobagarius group” of species formerly placed in Akysis. The status of 228 species group names remains unresolved and 31 names based on otoliths ascribed to catfishes are listed but not placed into the checklist. The current emphasis given to catfish taxonomy at present is likely to result in a dramatic increase in the total number of valid taxa as well as major changes in the membership of some of the higher level taxa recognized here.

The genus Sarcotretes, parasitic copepods from midwater and demersal fishes in the Atlantic Ocean, is reviewed. The taxonomic status of the six nominal species is discussed. Two species, S. scopeli, from midwater fishes, and S. eristaliformis, from demersal fishes, are tentatively considered valid members of the genus. The remaining species (S. inflexus, S. lobatus, S. gempyli, and S. nodicornis) are probable synonyms of the type species, S. scopeli. A detailed description of S. scopeli from six midwater host species is presented.

Primary Literature

ABSTRACTThe genus Machaeroprosopus has long been considered invalid because the type specimen of the Late Triassic phytosaur species, M. validus, has been lost. Re-examination of the primary literature regarding the establishment of the Late Triassic phytosaur genus Machaeroprosopus demonstrates that M. buceros is the correct type species, not M. validus. Thus, the genus level name Machaeroprosopus has priority over the genera Pseudopalatus and Arribasuchus and all nominal species should be reassigned. Reassignment of these species to Machaeroprosopus satisfies the requirements of the International Code of Zoological Nomenclature (ICZN) and preserves historical context. The name Pseudopalatinae is retained as the valid clade name for these phytosaurs because its usage falls outside of the ICZN.

The hydrozoan genus Zyzzyzus is revised based on reexaminations of all available type specimens and on additional material. The taxon includes four valid species: Zyzzyzus spongicolus (von Lendenfeld, 1884), from the eastern Indian and southwest Pacific oceans; the type species, Z. warreni Calder, 1988, from the Atlantic, western Indian, and western Pacific oceans; and Z. floridanus Petersen, 1990 and Z. robustus Petersen, 1990, both from the northwest Atlantic. Although type specimens of Z. calderi Petersen, 1990 could not be located, it has been assigned here to the synonymy of Z. warreni because of similarities between the two in nematocyst dimensions, in number and structure of endodermal canals, and in external morphology of the hydrocaulus and hydrorhiza. A sixth nominal species (Corymorpha iyoensis Yamada, 1958) has on one occasion been assigned to the genus, but detailed studies of the type material are needed to resolve its taxonomic affinities.

The genus Quasimodia Sheard, 1936 belongs to the hyaloidean family Phliantidae, and contains four species inhabiting littoral and sublittoral habitats in Australia (J.L. Barnard 1972; Lowry & Stoddart 2003; Horton et al. 2018; Lowry & Myers 2019). This genus-group name was originally erected for three nominal species—Q. barnardi Sheard, 1936, Q. capricornis Sheard, 1936, and Q. womersleyi Sheard, 1936 (see Sheard 1936), but its type species was not fixed in the original publication. As such the name Quasimodia Sheard, 1936 is not available for nomenclatural purposes (Article 13.3 of the International Code of Zoological Nomenclature [hereafter Code], International Commission on Zoological Nomenclature 1999). Later, J.L. Barnard (1969) selected Q. womersleyi as the type species for this genus-group name, but his action does not validate Quasimodia Sheard, 1936, which remains unavailable, under Article 69 of the Code. J.L. Barnard (1972) again incorrectly considered Quasimodia Sheard, 1936 as an available name.
