Revision of the Traumatomutilla juvenilis species group (Hymenoptera,Mutillidae)

ABSTRACT

Traumatomutilla duplicata duplicata (Gerstaecker, 1874), T. duplicata feia Casal, 1969, T. bruchi André, 1908, T. cristata (Gerstaecker, 1874), T. aterrima (Gerstaecker, 1874) and T. lorena (Cresson, 1902) are proposed as junior synonyms of Traumatomutilla bivittata (Gerstaecker, 1874). Traumatomutilla immaculiceps André, 1901, T. bivittata rubroguttata André, 1901 and T. estrella (Cresson, 1902) are proposed as junior synonyms of T. juvenilis (Gerstaecker, 1874). Traumatomutilla bispiculata (André, 1907) is proposed as a junior synonym of T. miniata (Gerstaecker, 1874). The previously unknown males of T. guarata Casal, 1969 and T. juvenilis are described and illustrated. All species of the T. juvenilis species group are redescribed and illustrated. A new species, Traumatomutilla juvenindica Bartholomay & Williams sp. nov., is described based on males and females from northern South America. Additionally, identification keys to the species and known colour forms of the T. juvenilis species group are provided.

Water mites of the family Hygrobatidae Koch from southern Africa (Acari: Hydrachnidia)

New records are given of the water mite family Hygrobatidae (without the genus Atractides) from southern Africa (South Africa, Botswana, Namibia). In addition to one new subgenus of the genus Hygrobates, namely Inflatibates, four new species are described, namely Hygrobates draconicus, H. laceratoides, H. okavangoensis, and H. inflatipes as well as one new subspecies, namely Hygrobates spathuliferus cederberg. The following synonyms are established: the subgenus Capobates Thor with Hygrobates Koch, Hygrobates sanguineus transvaalensis K. O. Viets with Hygrobates spathuliferus (Lundblad), and Ambiguobates permixtus agnewi K. O. Viets with Ambiguobates permixtus K. Viets. The male of Australiobates pilosus (K. Viets) is described for the first time. The synonymization of Diversibates with Australiobates can now be confirmed. Finally, keys are given for the known genera of southern Africa, as well as for all known species of the genus Hygrobates from southern Africa.     

Revision of the obligate mushroom‐feeding African “dung beetle” genus Coptorhina Hope (Coleoptera: Scarabaeidae: Scarabaeinae)

The African genus Coptorhina Hope is revised. Nine new synonymies are established which reduces the number of valid names from 15 to six. One new species is also described. The name changes are the following: C. subaenea Janssens, C. bicolor Ancey, C. pygmaea Balthasar and C. saganicola Müller are considered junior synonyms of C. nitidipennis Boheman; C. africana Hope, C. vicina Péringuey, C. obtusicornis Boheman, C. punctata Ferreira and C. optata Péringuey are considered junior synonyms of C. klugii Hope. The new species, C. excavata sp. n., is described from southern Africa. A key to the species and notes on biology are given.     

Taxonomy of the genus Oriverutus Siddiqi, 1971 (Nematoda: Dorylaimida: Nordiidae)

After introducing its history, the most relevant morphological features of Oriverutus are explained, illustrated (light and scanning electron microscope pictures) and discussed. The taxonomy of the genus is analysed based on the study of all the nominal species, and an emended diagnosis is provided. Its relationships with the closest genera are discussed, and some reflections are made on its phylogeny. Ecanema and Mammillonema are confirmed as junior synonyms of Oriverutus, Inbionema is regarded as its junior synonym also, whereas Paroriverutus is considered to deserve separate generic status. Consequently, several nomenclatorial changes are derived: Paroriverutus ivorensis is retained under Paroriverutus, Drepanodorylaimus macramphidius and Oriverutus longicaudatus are transferred to Paroriverutus, and Inbionema biforme to Oriverutus. An updated list of Oriverutus species is provided as well as a key to the identification of its didelphic species and a compendium of their morphometrics.     

A re-examination of 11 species of Otostigmus from the Indo-Australian region described by R. V. Chamberlin based on type specimens in the collection of the Museum of Comparative Zoology,Harvard (Chilopoda; Scolopendromorpha; Scolopendridae)

As a contribution to a revision of the scolopendromorph centipede subgenus Otostigmus of the genus Otostigmus, the type specimens of 11 species described by R. V. Chamberlin from the Indo-Australian region and in the collection of the Museum of Comparative Zoology at Harvard have been redescribed. Of these 11, six are junior synonyms of other Otostigmus species, one is a junior synonym of Rhysida longipes longipes (Newport, 1845) and one a nomen dubium. Only three, namely, Otostigmus amballae Chamberlin, 1913, Otostigmus proponens Chamberlin, 1920 and Otostigmus pamuanus Chamberlin, 1920 are valid.     

A review of the South-East Asian Nasutitermitinae (Isoptera: Termidae), with descriptions of one new genus and a new species and including a key to the genera

This paper describes Snootitermes leuserensis, gen. et sp. nov. (collected from the Leuser Ecosystem, Sumatra), Hirtitermes brabazoni sp. nov. (collected from north Sulawesi) and the major soldier of Ceylonitermes indicola. It also includes a revised generic key to the Nasutitermitinae of Peninsular Malaysia, Java, Sumatra and Borneo and reassigns the South-East Asian Subulitermes-group of termites to the Nasutitermes-group. Aciculioiditermes denticulatus and A. sarawakensis are considered to be junior synonyms of Aciculioiditermes holmgreni. The genera Aciculioiditermes and Proaciculitermes are considered to be junior synonyms of Malaysiotermes. Therefore Aciculioiditermes holmgreni, Proaciculitermes orientalis, P. sabahensis, P. malayanus and P. lowi are all Malaysiotermes species. Tho's (1982, 1992) unpublished new genus (Genus A) is considered to be a new species of Ceylonitermes. Oriensubulitermes borneensis is shown to be a Subulioiditermes species, S. borneensis. Nasutitermes matangensiformis is shown to be a junior synonym of N. matangensis. Havilanditermes is shown to be a junior synonym of Nasutitermes.     

Revision of the genus Erythracarus Berlese (Acarina: Anystidae: Erythracarinae)

The mite genus Erythracarus is revised and redefined and the new pyrrholeucus species group is described. The type species of Erythracarus is established as E. ruricola and the previous designation of Trombidium parietinum as the type is thus declared invalid. Bechsteinia and Chabrieria are newly synonymized with Erythracarus. Nine new species are described: Erythracarus amnicolus n. sp., E. avius n. sp., E. barbarus n. sp., E. ciliatus n. sp., E. decoris n. sp., E. elegans n. sp., E. flavipes n. sp., E. katherinae n. sp. and E. nasutus n. sp. The species E. parietinus, E. pyrrholeucus, E. festinus and E. grahami are redescribed and identification keys to known species and instars of Erythracarus are presented. E. cluozzai is made a junior synonym of Tarsolarkus articulosus, Bechsteinia solarii and Erythraeus spinatus are made junior synonyms of Erythracarus parietinus, while Bechsteinia californica, B. schneideri and Tarsotomus terminalis are all made junior synonyms of E. pyrrholeucus. E. simku is found to be a nomen nudum. E. pyrrholeucus is recorded for the first time from Australia, Iran and the Ukraine and E. parietinus for the first time from the western United States. The only record of E. parietinus from Australia is shown to be based on a misidentification. Observations on reproductive behaviour are made for five Erythracarus species. All of these reproduce sexually by means of stalked spermatophores, the shape of which is species specific. Spermatophores are often deposited on top of one another, possibly indicating sperm competition. Males of one species, E. pyrrholeucus, are unknown and this species is thus likely to be thelytokous. Some Erythracarus species are oviparous. E. ciliatus and E. parietinus are ovoviviparous or viviparous. Prelarvae that were studied were immotile except for those of E. ciliatus, which were able to move their legs. Immotility is a derived character state in Erythracarus and possibly an adaptation to more protected habitats.     

A revision of Bovichtus Cuvier, 1831 (Pisces: Bovichthyidae) from Australasia,with description of a new deepwater species from the New Zealand Subantarctic

The genus Bovichtus includes four species from the Australasian region, viz. B. variegatus Richardson, B. psychrolutes Günther, B. angustifrons Regan, and B. oculus n. sp. B. decipiens Regan and Aurion effulgens Waite are junior synonyms of B. variegatus and B. psychrolutes respectively. B. oculus, described from a specimen taken in 847–902 m on the Campbell Plateau in the New Zealand Subantarctic, is the first known deep water Bovichtus species. It differs from all congeners in having a very large eye (horizontal diameter <9·0 times in SL) and, alone with B. psychrolutes, has a patch of ctenoid scales on the body behind the pectoral fin base.     

Water mites of the genus Hygrobates Koch, 1837 (Acari: Parasitengona: Hygrobatidae) from Hokkaido,northern Japan

Nine species of Hygrobates (Acari: Parasitengona: Hygrobatidae) from Hokkaido, Japan are described or redescribed from newly collected material and historical specimens. Treated herein are eight species in the subgenus Hygrobates, including one new species, H. bibi sp. nov., as well as H. calliger Piersig, ; H. foreli (Lebert, ); H. japonicus Uchida, ; H. longipalpis (Hermann, ); H. longiporus Thor, ; H. nigromaculatus Lebert, ; and H. sokolowi Thor, . Also treated is H. ezoensis Uchida, in the subgenus Rivobates. A lectotype and paralectotype are designated for H. japonicus Uchida, . Hygrobates (s. str.) heteropalpis Imamura, is synonymized with H. calliger Piersig, . The name H. ezoensis Uchida, is resurrected from synonymy with H. diversiporus Sokolow, . Six species previously known from Hokkaido were collected in the study: H. foreli, H. japonicus, H. longipalpis, H. longiporus, H. diversiporus, and H. ezoensis. New records for both Hokkaido and Japan include H. nigromaculatus and H. sokolowi. A species previously recorded from Hokkaido, H. taniguchii Imamura, , was not found in this study. Three new characters are proposed as useful for the taxonomy of the genus Hygrobates: the ratio of the distance between the P‐4 ventral setae to P‐4 length, the ratio of the length of the longest terminal seta on IV‐L‐5 to the length of IV‐L‐5, and the nature of the outer border of the genital plates.     

Designation of a neotype for Synodontis schall (Bloch and Schneider, 1801) and description of two new species of Synodontis (Siluriformes: Mochokidae)

A morphometric study of 105 specimens of Synodontis schall, including most type specimens of all nominal species considered junior synonyms of S. schall has been undertaken. Two new species S. ouemeensis and S. kogonensis are described from the Ogun (Nigeria), Oueme (Benin) and Mono (Togo) basins, and the Kogon and Fatala (Guinea) basins, respectively. A neotype is designated for S. schall. The two new species differ from S. schall mainly by the width of the premaxillary toothplate (12.9–24.3% HL for S. schall vs. 21.6–32.7% HL), and can be distinguished one from the other by differences in orbit diameter (20.5–26.8% HL for S. ouemeensis vs. 19.4–21.0% HL for S. kogonensis) and prepectoral length (23.4–28.2% SL for S. ouemeensis vs. 21.6–23.3% SL for S. kogonensis).     

A review of the north-western Pacific species of the genus Paguristes (Decapoda: Anomura: Diogenidae), I. Five species initially reported by Ortmann (1892) from Japan

Five species of the hermit crab genus Paguristes Dana, 1851, initially reported by Ortmann (1892) from Japan, are revised based on the materials reported by Ortmann (1892), Doflein (1902), Balss (1913) and Miyake (1978), and on newly collected specimens. The specific status of P. palythophilus Ortmann, 1892, is clarified, and a species confused with P. palythophilus is described as new, P. albimaculatus. It has been revealed that P. kagoshimensis Ortmann, 1892, is actually a junior subjective synonym of P. digitalis Stimpson, 1858. The species heretofore assigned to P. kagoshimensis is described as new, P. versus. It has been confirmed that Paguristes acanthomerus Ortmann, 1892, is a valid species and that P. barbatus sensu Ortmann, 1892, is the same species as P. ortmanni Miyake, 1978. Further, a new species, P. doederleini, is described for P. setosus sensu Ortmann, 1892. It is also shown that a part of the group of specimens identified as Paguristes puniceus by Miyake (1978) is referable to P. doederleini. In addition to the three new species recognized herein, the four previously described species are also redescribed in detail in order to make clear their taxonomic status.     

Antheluridae,a new family of Crustacea (Isopoda: Anthuridea) with new species from Australia

The Antheluridae is erected for the genera Anthelura Norman and Stebbing, Ananthura Barnard and Anthomuda Schultz. The family is characterized by mouthparts of biting form; maxillipedal endite broad; maxillipedal palp broad, of 4–5 free articles; several posterior carpal and propodal spines on pereopods 2–7; pereopod 7 with transverse anterodistal propodal setal row on mesial face; and single telsonic statocyst. Its relationships to other anthurideans, especially the Paranthuridae, is discussed. Three new Australian species are described, Ananthura billarderia from off New South Wales, Anthomuda chorizema from the southeastern coast, and Anthomuda hovea, from the Great Barrier Reef, Coral Sea islands and Western Australia.

Bathura Schultz, Austranthura Kussakin and Valoranthura Kensley are junior synonyms of Ananthura, and Diaphoranthura is a junior synonym of Anthomuda.     

Taxonomy of the genus Tantunema Siddiqi, 1982 (Dorylaimida: Tylencholaimidae) with description of one new and two known species

One new and two known species of the genus Tantunema Siddiqi, 1982 are described and illustrated. Tantunema indicum sp. nov. is characterized by having a small body (length 0.32–0.45 mm); lip region cap-like, set off by slight constriction; odontostyle 6–7 µm and odontophore 8–10 µm long; pharyngeal expansion gradual, expanded part occupying about 35–41% of total neck length, lumen of posterior expanded part widened and thickened; female genital system mono-opisthodelphic, anterior genital branch absent; tail short, hemispheroid, 0.8–1.1 anal body diameter long. Tantunema pakistanense (Timm, 1964) comb. nov. (=Tylencholaimus pakistanensis Timm, 1964) and Tantunema intermedium (Peña-Santiago and Coomans, 1996) Andrássy, 2009 are redescribed. A diagnostic compendium and key to species of the genus is also provided.     

Historical review and redescription of three poorly known species of the catfish genus Trichomycterus from south-eastern Brazil (Siluriformes: Trichomycteridae)

ABSTRACT

This study is primarily directed to the most poorly known species of the genus Trichomycterus, comprising five nominal species (T. florensis, T. immaculatus, T. nigricans, T. paquequerensis and T. santaeritae) endemic to south-eastern Brazil. One of them, T. nigricans, is the type species of the genus, involved in taxonomic problems for over 150 years. A detailed historical review, accompanied by examination of type specimens and recent collections, revealed that the correct type locality of T. nigricans is in the vicinity of Rio de Janeiro, not Santa Catarina as commonly appears in the literature; specimens previously misidentified as T. nigricans from Santa Catarina belong to a possibly undescribed species of the genus Cambeva; T. paquequerensis is a synonym of T. immaculatus, and T. florensis is a synonym of T. santaeritae; and the hypothesis that T. santaeritae is closely related to the Amazon Sarcoglanidinae is refuted. The three valid species are redescribed. These species are members of a clade also including T. caipora that is highly supported by molecular data, diagnosed by a pronounced posterior maxillary process and caudal fin emarginate at least in larger specimens. A subclade comprising T. caipora, T. nigricans and T. santaeritae is diagnosed by a long maxilla and a bifid anterior extremity of hypobranchial 3.     

Stenothoidae (Crustacea: Amphipoda) of hydrothermal vents and surroundings on the Mid‐Atlantic Ridge,Azores Triple Junction zone

Four new species of Stenothoidae were collected from the Azores Triple Junction zone during different French cruises on the Mid‐Atlantic Ridge. One of the species belongs to the genus Torometopa (T. saldanhae) and is the first record of this genus in the Atlantic Ocean. The three other species belong to the genus Stenothoe (S. divae, S. marvela, and S. menezgweni). It is not possible to determine from morphological and ecological characters whether these amphipod species are endemic to hydrothermal systems or are bathyal species that may be found away from vent sites.     

A phylogenetic and biogeographic study of Euniphysa (Eunicidae,Polychaeta)

Fourteen species have either been described in, or referred to, the genus Euniphysa. Seven of these are here re-described based on type material and two new species, E. quadridentata and E. filibranchia, are described. Euniphysa oculata is found to be a subjective synonym of E. spinea, and E. unicusa is a subjective synonym of E. aculeata. Euniphysa taiwanensis and E. megalodus are correctly assigned to the genus, but cannot be described due to lack of material. Euniphysa misakiensis, E. tubicola and E. tubifex are transferred to Eunice. A key is given to the nine identifiable species retained in Euniphysa. Coding strategies for polymorphic and inapplicable characters, as well as problems associated with shared absences, are discussed. A phylogenetic analysis of Euniphysa based on 24 morphological characters yielded two most parsimonious trees (CI = 0.902, RI = 0.905). The tree topology separates Euniphysa into two distinct groups. Group I includes E. filibranchia n. sp., E. italica, E. jeffreysii, E. quadridentata n. sp. and E. spinea, it is supported by five equivocal similarities. Group II is supported by five unequivocal synapomorphies and two equivocal similarities, it includes E. aculeata, E. auriculata, E. falciseta and E. tridontesa. Based on the phylogenetic topology, Paraeuniphysa and Heterophysa are considered as junior synonyms of Euniphysa. The recognition of a separate family for Euniphysa is not warranted. All species of Euniphysa are fragile, shallow, warm water species. They have been collected mainly from sandy sediments of the Northern Hemisphere. The greatest diversity is from the South China Sea area; other species are found throughout the Indian Ocean, the Mediterranean Sea and the East Atlantic Ocean coasts suggesting the genus may have originated in the Tethys Sea. A few species have also been found in the Gulf of Mexico and the West Atlantic Ocean coast again suggesting a Tethyan origin associated with the westward drift of the North American continent.     

On some African and Oriental Wolf Spiders (Araneae,Lycosidae): redescription of Pardosa oncka Lawrence from Africa,with notes on its generic position

Pardosa oncka Lawrence (with P. irrasa Roewer, P. kisokwea Roewer, P. resoluta Roewer, P. versuta Roewer and P. wittei Roewer here placed as junior synonyms) is described and illustrated. The male is recognized by its bifurcate embolus. The female has conspicuous mating plugs more or less concealing two pits in the epigyne. The species is widely distributed in Central and South Africa, and may be grouped in a separate genus (here not formally recognized) together with P. venatrix auctt. and some other species listed.     

A key to Australasian and Oriental Woodiphora (Diptera: Phoridae), affinities of the genus and description of new species

The taxonomic value of the notopleural cleft in Phoridae is highlighted. A cladogram relating Gymnophora and Woodiphora to Megaselia is presented. Recognition of the genus Woodiphora is clarified, and the Old World species of Haplophleba transferred to Woodiphora. The evolution of the female abdominal sternite 9 is discussed. The tribe Megaseliini is proposed. A key to the Australasian and Oriental species of Woodiphora is provided. Twenty new species are described and two new synonyms proposed.     

A revision of the genus Platythelphusa A. Milne-Edwards, 1887 from Lake Tanganyika,East Africa (Decapoda: Potamoidea: Platythelphusidae)

The genus Platythelphusa is revised and six species are recognized. These species are P. armata A. Milne-Edwards, 1887, P. maculata (Cunnington, 1899), P. conculata Cunnington, 1907, P. tuberculata Capart, 1952, P. polita Capart, 1952 and P. echinata Capart, 1952. A seventh taxon, P. denticulata Capart, 1952 is considered here to be a junior synonym of P. conculata. A diagnosis for each species is provided and most are figured from the type. Keys to the families of African freshwater crabs and to the genus Platythelphusa are also provided.
