African Genus

Type specimens of all three nominal species of the East African genus Molytophilus Hartmann are studied and illustrated. The genus is taxonomically restricted to include only the type species M. carinatus Hartman known from two collecting events in Tanzania and Somalia. Both other species of Molytophilus, described from Ethiopia, are herein transferred to the genus Oreoscotus as O. affinis (Hustache, 1936) comb. n. and O. puncticollis (Hustache, 1936) comb. n. A lectotype is designated for Molytophilus carinatus Hartmann. Type specimens of all three nominal species are illustrated.

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.

Nereididae Johnston, 1865, part of the large clade Phyllodocida, is one of the best-known annelid groups. Presently, there are some 500 nominal species grouped into 42 genera, although there is little consensus among different authors as to how they should be classified. The relationships of nereidids were assessed in a morphology-based parsimony analysis of 41 terminal taxa, with members of Chrysopetalidae and Hesionidae used as outgroups. Type species for the majority of currently recognised nereidid genera were used as terminal taxa, and character information was based on examination of type and non-type specimens, together with literature descriptions. High degrees of homoplasy were found for several features that are traditionally applied to delineate subgroups of Nereididae, including the presence of paragnaths and the distribution of different kinds of chaetae. Six major groups were recovered: Namanereidinae, including Namalycastis and Namanereis, characterised by spherical shape of palpostyles and ventrally displaced notoaciculae; one clade corresponding in part to previous authors concepts of Nereidinae, including Nereis, Eunereis, Hediste and Platynereis (the relationships of several well known nereidids, such as Neanthes and Perinereis, commonly referred to Nereidinae, could not be unambiguously resolved); one unnamed and not previously recognised clade (A), including Australonereis, Laeonereis, Dendronereides and Olganereis, characterised by the presence of papillae on the maxillary ring; a second unnamed clade (B), including Leptonereis, Sinonereis, Tylonereis and Tylorrhynchus, characterised by enlarged notopodial ligulae; a well supported Gymnonereidinae, restricted to Ceratocephale, Gymnonereis, Tambalagamia and Micronereides; and a third unnamed clade (C), including Ceratonereis, Solomononereis, Unanereis, Cheilonereis and Websterinereis, characterised by unilobated neuropodial postchaetal lobes. Among these groups we found good support for the Namanereidinae, the Gymnonereidinae and for the whole of Nereididae. The subfamilies Dendronereidinae and Notophycinae (based on Micronereis, senior synonym of Notophycus) are regarded here as monotypic.

The nominal genera Chelomalpheus Kim, 1998 and Cavipelta Hayashi, 1998 were treated as synonyms of Stenalpheops Miya, 1997 in the paper by Anker et al. (2001). Therefore, the type species of those genera (Chelomalpheus koreanus Kim, 1998 and Cavipelta yamashitai Hayashi, 1998, respectively) were synonymized with S. anacanthus Miya, 1997. Actually, those authors ignored that the morphological characters of the three species mentioned above show differences. For instance, all type specimens of Chelomalpheus koreanus Kim, 1998 are without a caudal appendix; the large male specimens of Cavipelta yamashitai Hayashi, 1998 have an abnormal shaped chela, which corresponds with the middle stage in a growth series of another nominal species, i.e., S. anacanthus. The opportunity to study abundant specimens from the China seas established that the type specimens of S. anacanthus Miya, 1997 are in fact composed of two species, and the same was found for the type specimens of Cavipelta yamashitai Hayashi, 1998; in addition, Chelomalpheus koreanus Kim, 1998 was found to be a valid species and is transferred to Stenalpheops; and S. crangonus (Anker, Jeng & Chan, 2001) is herein synonymized with S. anacanthus Miya, 1997, which name has priority, and this valid species is now re-described herein.

A taxonomic review of the cosmopolitan genus Filellum was performed considering morphology, morphometry and cnidome. Species for which we had access to materials were redescribed and morphologically characterized based on optical and scanning electron microscopy (SEM). The materials examined belong to museum collections, including type specimens. All records found in the literature were checked. Our analyses confirmed the validity of 10 out of the 18 nominal species referred to the genus, and established four others (F. adnatum, F. bouvieri, F. contortum and F. plicatum) as species inquirenda. A new species, Filellum bouvetensis sp. nov., is described. The species Reticularia annulata Watson, 1973, type species of the genus Corystolona Watson, 2002, has its type specimen referred to the genus Filellum, composing Filellum annulatum (Watson, 1973). We provide a key for the identification of the valid species of the genus Filellum.

The new genus Tropostreptus is erected to accommodate seven species which are all endemic in Tanzania: T. hamatus (Demange, 1977) (type species, = Spirostreptus hamatus Demange, 1977), T. sigmatospinus sp. nov., T. microcephalus sp. nov., T. droides sp. nov., T. kipunji spec. nov., T. austerus (Attems, 1950) (= Epistreptus austerus Attems, 1950) and T. severus sp. nov. All but one (T. sigmatospinus) of the species are restricted to the Eastern Arc Mts. in a wide sense, i.e., including Mt. Rungwe. Notes are included on Rickia gigas Santamaria et al., 2016 (Ascomycota: Laboulbeniales), which infects several Tropostreptus species. The typical, long-celled form of R. gigas grows on body parts of both sexes coming into contact during copulation, whereas a short-celled form also ascribed to R. gigas grows on the hind margin of body rings of both sexes. A key to Tropostreptus species is included.

Species Being

Euconophron was described over a century ago and includes over 120 nominal species, being the third largest subgenus of Euconnus. However, its diagnosis remains unclear. Western Palaearctic species seem to form a homogenous group characterized by emarginate or bifurcate aedeagal apex, whereas exotic members of this subgenus show a great diversity in external and genital characters. Moreover, Scopophus, a Nearctic subgenus of Euconnus, and at least some species placed in Euconnus s. str. outside Europe seem to be very similar to Euconophron. In the present paper the status of Euconophron and Scopophus is verified on the basis of morphological structures of their type species, i.e., Scydmaenus promptus Coquerel (the type species of Euconophron) and Euconnus affinis Casey (the type species of Scopophus), each represented by respective type specimens. It is concluded that: i) the redescription of Scydmaenus promptus published by H. Franz was based on a misidentified specimen; ii) Euconophron can be maintained as a separate subgenus if unique characters of western Palaearctic species are included in its diagnosis; iii) Scopophus is a junior synonym of Euconnus s. str.; iv) status of species currently placed in Euconophron that occur outside western Palaearctic seems dubious, some of them may belong in Euconnus s. str. (this problem requires further study and species redescriptions); v) Euconnus s. str. and Euconophron may be closely related. Emended diagnosis of Euconophron is given, and lectotypes are designated for Scydmaenus promptus and Euconnus affinis.

The Family

Concepts of the family Hyolithidae Nicholson fide Fisher and the genera Hyolithes Eichwald and Orthotheca Novak have been expanded through time to encompass a variety of morphologically dissimilar shells. The Hyolithidae is here considered to include only those hyolithid species which have a rounded (convex) dorsum; slopes on the dorsum are inflated, and the venter may be flat or slightly inflated. Hyolithes encompasses species which possess a low dorsum and a prominent longitudinal sulcus along each edge of the dorsum; the ligula is short and the apertural rim is flared. The emended concept of Orthotheca includes only those species of orthothecid hyoliths which have a subtriangular transverse outline and longitudinal lirae covering the shell on both dorsum and venter.Eighteen species of Hyolithes and one species of Orthotheca from the Appalachian region and Western Interior were reexamined in light of more modern taxonomic concepts and standards of quality for type material. Reexamination of type specimens of H. similis Walcott from the Lower Cambrian of Newfoundland, H. whitei Resser from the Lower Cambrian of Nevada, H. billingsi Walcott from the Lower Cambrian of Nevada, H. gallatinensis Resser from the Upper Cambrian of Wyoming, and H. partitus Resser from the Middle Cambrian of Alabama indicates that none of these species represents Hyolithes. Hyolithes similis is here included under the new genus Similotheca, in the new family Similothecidae. Hyolithes whitei is designated as the type species of the new genus Nevadotheca, to which H. billingsi may also belong. Hyolithes gallatinensis is referred to Burithes Missarzhevsky with question, and H. partitus may represent Joachimilites Marek. The type or types of H. attenuatus Walcott, H. cecrops Walcott, H. comptus Howell, H. cowanensis Resser, H. curticei Resser, H. idahoensis Resser, H. prolixus Resser, H. resseri Howell, H. shaleri Walcott, H. terranovicus Walcott, and H. wanneri Resser and Howell lack shells and/or other taxonomically important features such as a complete aperture, rendering the diagnoses of these species incomplete. Their names should only be used for the type specimens until better preserved topotypes become available for study. Morphology of the types of H.? corrugatus Walcott and “Orthotheca” sola Resser does not support placement in the Hyolitha; the affinities of these species are uncertain.

Initial Focus

The tridentigerine genus Pseudogobius is widespread, from temperate to tropical areas of the Indo-west Pacific. A morphological review of the genus was carried out, with the initial focus on South-east Asian and Australian species. There are about 21 nominal species in the genus; however, the type specimens for some nominal species are missing. Our work recognises 15 valid species so far, including seven new species, which are described herein: P. aquilonius n. sp., P. cinctus n. sp., P. eos n. sp., P. hoesei n. sp., P. jeffi n. sp., P. rhizophora n. sp. and P. verticalis n. sp. We also conclude that P. poicilosoma (Bleeker, 1849) is the senior synonym of P. javanicus (Bleeker, 1856). Pseudogobius poicilosoma, P. gastrospilos (Bleeker, 1853) and P. javanicus are accepted here as conspecific, although the types are in poor condition (note that all three names were given to specimens collected within close proximity to each other in coastal Java, Indonesia). A key to valid species is presented. The revision benefited from an adaptive feedback loop with companion genetic analyses, with the most comprehensive data available for the Australian region. Broader preliminary genetic data suggest the potential for recognition of additional cryptic species, with the current study providing a platform for future systematic work. Pseudogobius are a prominent part of estuarine biodiversity in the Indo-west Pacific, and this study helps to highlight the need to better understand the taxonomy and conservation requirements of cryptobenthic fishes.
