CVIII.—The African spiders of the family Ctenidae in the collections of the British Museum (Natural History)

Summary

The African Ctenidae in the Collections of the British Museum (Natural History) are revised. Thirty species are contained in the subfamilies Cteninae and Acantheinae. Ctenus batesii Pocock, 1903, is a synonym of Ctenus capulinus (Karsch), 1879, Ctenus dirus Thorell, 1899, is a synonym of Ctenus kingsleyi F. O. P.-Cambridge, 1898, Ctenus marshalli F. O. P.-Cambridge, 1898, is a synonym of Ctenus melanogastra (Bösenberg & Lenz), 1895, and Ctenus spenceri F. O. P.-Cambridge, 1898, is a synonym of Ctenus pulchriventris Simon, 1896.

The subfamily Acantheinae is recorded from Africa for the first time. A new genus, Africactenus, is erected for a group of allied species. The genotype is Ctenus agilior Pocock, 1899, and the following new species are described:—A. depressus, A. desartsi, A kribiensis, A. pococki, A. sandersoni, A. simoni, A. sladeni, A. tridentatus and A. trilateralis. Ctenus longurio Simon, 1909, is transferred to the genus Africactenus on examination of the type-material.

Certain species from the Simon Collection are listed in the Appendix and figured for the first time.     

A new species of dorid nudibranch of the genus Taringa Marcus, 1955 (Mollusca: Opisthobranchia) from the southern Iberian peninsula,with remarks on world species of the genus

A new dorid nudibranch from the southern Iberian peninsula is described. Taringa tarifaensis n. sp. is subtidal and has been found under stones. A comparison between T. tarifaensis and the other known species of the genus is presented, as well as some remarks on the taxonomic status of the genus Taringa.     

A taxonomic study on the Phtisicidae (Crustacea: Amphipoda) of New South Wales,Australia

The present study reviews the taxonomy of the Phtisicidae (Crustacea: Amphipoda) from the coast of New South Wales, Australia. The following seven species are described; Dodecas decacentrum Stebbing, 1910b, Dodecas hexacentrum Mayer, 1903, Hircella cornigera (Haswell, 1879b), Metaproto novaehollandiae (Haswell, 1879a), Notoprotomima smithi gen. nov., sp. nov., Paraproto sp. and Perotripus sp. Generic diagnoses of Notoprotomima gen. nov., Dodecas, Hircella and Metaproto are provided based on the present materials. Notoprotomima smithi is fully described as a new species of the new genus. Dodecas decacentrum differs from Dodecas hexacentrum by the presence of paired dorsodistal projections on pereonite 2, paired mid-dorsal projections on pereonites 3 and 4 and shorter gill length on pereonites 2 and 3. Hircella cornigera and Metaproto novaehollandiae are described in detail. The larger mature males of M. novaehollandiae possess the unusual massive type of the propodus of gnathopod 2. The extended distribution of Perotripus to the New South Wales coast is noted. A key for these phtisicid amphipods from New South Wales, Australia is provided.

Some anisakid nematodes from marine fishes of Japan and the North Pacific Ocean

A recent collection of anisakid nematodes from marine fishes from Japan and the North Pacific Ocean comprised a total of seven species of two genera; six of them (Raphidascaroides nipponensis Yamaguti, 1941, Hysterothylacium aduncum aduncum (Rudolphi, 1802), H. auctum (Rudolphi, 1802), H. cornutum (Stossich, 1904), H. marinum (Linnaeus, 1767) and H. physiculi sp. n.) parasitize fishes as adults, whereas one (Hysterothylacium sp.) occurred as larvae encapsulated in the host's abdominal cavity. Hysterothylacium physiculi sp. n. from the intestine of the gadiform fish Physiculus maximowiczi (Herzenstein) (family Moridae) from the western North Pacific (Kamaishi Bay, Honshu) is characterized mainly by shape of the lips, presence of well developed lateral alae starting some distance posterior to base of the lips, a short caecum, and markedly short (324-416mum) spicules. SEM study of R. nipponensis, type species of the genus, did not confirm the presence of dentigerous ridges on the lips. All species are briefly described and illustrated and some taxonomic problems are discussed. Several new host and geographical records are presented.     

Model mimics: antlike jumping spiders of the genus Myrmarachne from Sri Lanka

All nominal species of ant-mimicking jumping spiders of the genus Myrmarachne from Sri Lanka are redescribed, based on type and newly collected material. Three new species are described: Myrmarachne aurantiaca sp. nov., M. dishani sp. nov. and M. morningside sp. nov. Panachraesta Simon, 1900 is shown to be a junior synonym of Myrmarachne MacLeay, 1839, syn. nov. The following species are synonymized: Myrmarachne orientales Tikader, 1973 = Myrmarachne melanocephala MacLeay, 1839 syn. nov., Myrmarachne paivae Narayen, 1915 and Myrmarachne bengalensis Tikader, 1973 = Myrmarachne prava (Karsch, 1880) syn. nov., Myrmarachne hanoii Zabka, 1985 = Myrmarachne pumilio (Karsch, 1880) syn. nov., Myrmarachne maratha Tikader, 1973 = Myrmarachne robusta (Peckham & Peckham, 1892). One new combination is proposed: Myrmarachne paludosa (Simon, 1900) comb. nov. Myrmarachne ramunni Narayan, 1915 is recorded for the first time in Sri Lanka. A total of 12 valid species are now known from the island; six of them are endemic.

Hysterothylacium,Iheringascaris and Maricostula new genus,nematodes (Ascaridoidea) from Australian pelagic marine fishes

The state of knowledge of Australian fish parasitic ascardioids is briefly reviewed. The following species are described in full: Hysterothylacium cornutum, H. pelagicum, H. scomberoidei n. sp. Additional data are provided for Iheringascaris inquies. Maricostula n. gen. is established for those species that have lips with lateral flanges, deep postlabial grooves, interlabia, and elongate intestinal caecum, pyriform ventriculus, long sac-like ventricular appendix, an expanded filamentar excretory system and excretory pore near the nerve ring. The males of all the species have precloacal crests. Species included are: M. caballeroi (Deloya), M. cenatica n. sp., M. histiophori (Yamaguti), M. incurva (Rudolphi), M. makairi n. sp. and M. tetrapteri n. sp. All are recorded from billfishes, and all but M. caballeroi are recorded from Australian waters. The systematic position of the genus is discussed. New characters of taxonomic utility used in the discrimination of fish parasitic ascaridoids are discussed. These include fine details of alae, male caudal crests and papillae. We demonstrate that these characters can be used to separate species of Maricostula. Remarks are also given on nomenclatural problems within the Indo-Pacific fish parasitic Ascardioidea.     

Observations on the “tenuis group” (Eutardigrada,Macrobiotidae) and description of a new Macrobiotus species

A new species of the tardigrade genus Macrobiotus is described. The species, designated M. ciprianoi n. sp., was isolated from a mixture of Provence broom leaf litter and mosses, and from rock mosses collected in the Sierra de Guadarrama, Madrid (Spain). Given that Macrobiotus ciprianoi n. sp. shares several characters to members of the “tenuis group”, we assessed the taxonomic homogeneity of the group. The new species differs from those of the “tenuis group” according to a unique set of characters related with claw shape, features of the buccal‐pharyngeal apparatus, and egg morphology. Our analysis of holotypes and/or paratypes of “tenuis group” species and other Macrobiotus species with similar characters (M. bondavallii and M. caelicola) reflects the heterogeneity of this group of species as currently described.     

A new genus with three new species of copepods from the family Diaixidae (Crustacea: Calanoida), and a redefinition of the family

Plankton samples taken in the Gulf of Carpentaria, Australia, yielded material of a new genus containing 3 new species: Anawekia spinosa gen. nov. et sp. nov., A. robusta sp. nov. and A. bilobata sp. nov., which are described herein. The family Diaixidae now contains 12 described species in 2 genera, 9 being in the genus Diaixis. It is noted that 3 of the Diaixis species (including the type species) share some features which are not shared with the remaining 6 species, and that these latter species should probably be placed into a third genus. An amplified redefinition of the family is given.     

Species of Oswaldella Stechow, 1919 (Cnidaria: Hydrozoa: Kirchenpaueriidae) from US Antarctic expeditions,with the description of three new species

Seventeen species of the genus Oswaldella Stechow have been studied, three of which are new to science (Oswaldella frigida sp. nov., O. medeae sp. nov. and O. monomammillata sp. nov.). The material studied was collected by several US Antarctic expeditions. Each species is described and figured, the systematic position amongst allied species is discussed and available data concerning autecology and geographical distribution are given. The remaining eight known species of the genus are also considered, regarding synonymy, autecology and geographical distribution. Finally, a general survey of the bathymetrical and biogeographical distribution of the known species of Oswaldella is given.     

Desmosomatidae and Nannoniscidae (Crustacea,Isopoda, Asellota) from bathyal and abyssal depths off North Carolina and their evolution

The deep-sea asellote isopod (Crustacea) species, belonging to the families Desmosomatidae and Nannoniscidae, were studied from R/V Eastward collections of Duke University from three study sites off North Carolina. The Desmosomatid isopod Eugerda svavarssonni n. sp. is described from Site Alpha at 620m. Eugerda latipes Hansen, previously known from boreal North Atlantic, is also reported from this upper slope site. Two new desmosomatid isopods, Mirabilicoxa hessleri n. sp. and M. alberti n. sp., and a new nannoniscid isopod Exiliniscus chandravoli n. sp. are also described from site Beta from 2700 to 3700 m. A nannoniscid isopod Leutziniscus jebamoni gen n., n. sp., and a desmosomatid isopod, Prochelator sarsi n. sp., are described from the deepest study site Omega in the Hatteras Abyssal Plain. A new genus, Nannoniscella is erected to accommodate Nannoniscoides bicustatus Siebenaller and Hessler, 1977. This paper also includes discussions on comparative morphology and sexual dimorphism in species of Mirabilicoxa, zoogeography of species of the genus Eugerda and phylogeny with emphasis on the genus Prochelator.     

Taxonomic review of a new genus,Diathera gen. n., from Southeast Asia (Lepidoptera,Geometridae: Larentiinae)

Diathera gen. n., a new larentiine genus from central and southwestern China, is described. Three new species are named and described: fluctuata sp. n., metacolorata sp. n. and brunneata sp. n. All species and their genitalia are described and illustrated. A key is provided and the monophyly of the genus and its relationships to the allied taxa are briefly discussed.     

A revision of the genus Ophiambix (Echinodermata: Ophiuroidea) including the description of a new species

The genus Ophiambix is revised and problems at higher taxonomic levels are discussed. The species Ophiambix aculeatus, O. meteoris and O. devaneyi are redescribed (based on new characters), and a new species O. epicopus is described from the Kermadec Islands, South Pacific. A pictorial key is presented to aid identification.     

Ooencyrtus marcelloi sp. nov. (Hymenoptera: Encyrtidae), an egg parasitoid of Heliconiini (Lepidoptera: Nymphalidae: Heliconiinae) on passion vines (Malpighiales: Passifloraceae) in Central America

A new species belonging to the genus Ooencyrtus Ashmead is described. Ooencyrtus marcelloi sp. nov. has been reared from eggs of Heliconiini (Lepidoptera: Nymphalidae, Heliconiinae) collected in Panama on Passiflora spp. The new species is compared with its closest Ooencyrtus species, i.e. O. caligo Noyes, O. neustriae Mercet, O. flavipes (Timberlake), O. camerounensis (Risbec), O. endymion Huang and Noyes and Ooencyrtus sp. “undet. C.” (from India). This represents the second record of Ooencyrtus from Heliconinae and the first record of this genus from Panama.
