Taxonomy of the bryozoan genera Oncousoecia,Microeciella and Eurystrotos (Cyclostomata: Oncousoeciidae)

The selection of Tubulipora lobulata Hincks, 1880 Hincks, T. 1880. A history of the British marine Polyzoa, London, , (UK): Van Voorst. [Crossref] , [Google Scholar] as type species when establishing Oncousoecia is interpreted as a deliberate misapplication of a name, the nominal species T. lobulata having been originally described by Hassall in 1841 Hassall, A. H. 1841. Supplement to a catalogue of Irish zoophytes.. Ann Mag Nat Hist., 7: 363–373. [Taylor & Francis Online] , [Google Scholar].

A history of British zoophytes, London, , (UK): Van Voorst. 2nd edition [Google Scholar]), has a different ancestrular morphology and an unbranched colony‐form. It is here transferred to Microeciella.     

Crab‐associated amphipods from the Falkland Islands (Crustacea,Peracarida)

Four species of associated amphipods were collected from the lithodid crab Paralomis granulosa in the Falkland Islands: Jassa kjetilanna n. sp. (Ischyroceridae), Gammaropsis monodi (Schellenberg, 1931 Schellenberg, A. 1931. Gammariden und Caprelliden des Magellangebietes, Südgeorgiens und der Westantarktis.. Further Zoological Results of the Swedish Antarctic Expedition 1901–1903, 2: 1–290.  [Google Scholar]) (Photidae), Aora karibu n. sp. (Aoridae), and Paramoera falklandica n. sp. (Eusiridae s.l.). The Gammaropsis was also found on the majid crab Eurypodius latreillei, where it seemed to be the only associate. A survey of all amphipod associations involving lithodid crabs is provided.     

The diverse Grania fauna (Clitellata: Enchytraeidae) of the Esperance area,Western Australia,with descriptions of two new species

Seven species of the marine enchytraeid genus Grania Southern, 1913 are described from sediments sampled during the 2003 International Workshop on the Marine Flora and Fauna of Esperance Bay and the Recherche Archipelago, on the southern coast of Western Australia. Two species are new to science, the euryhaline Tasmanian G. dolichura Rota and Erséus, 2000 Rota, E. and Erséus, C. 2000. Two new and peculiar species of Grania (Annelida: Clitellata: Enchytraeidae) inhabiting Tasmanian estuaries.. New Zealand Journal of Zoology, 27: 245–254. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar] represents a new record for the state, and the remaining four species were known from other parts of Western Australia. Grania quaerens sp. n. is recognized by having a high chaetal index ( = short chaetal foot), small coelomocytes, penial apparati with long whip‐like terminal stylets, conspicuous spermathecae with ectally bulbous ducts, and ectally granulated ampullae housing sperm rings in their ental region. Grania sperantia sp. n. is readily distinguishable by the complete lack of lateral chaetae, a multiple‐banded pattern of the clitellum, extremely long sperm funnels, and the intrasegmental location of the spermathecal pores. The latter new species and four others in the collection (G. bykane Coates, 1990 Coates, K. A. 1990. “Marine Enchytraeidae (Oligochaeta, Annelida) of the Albany area, Western Australia.”.

Perth: Western Australian Museum.  [Google Scholar]) are remarkable in possessing the head organ, a sensory structure unique to Grania that was not noted previously in Western Australian species. When considering the whole genus, the geographic pattern of the head organ appears southern‐centred: of the 17 species of Grania reported to possess it, as many as 13 inhabit the southern latitudes. The seventh species of the Esperance collection, G. vacivasa Coates and Stacey, 1993 Coates, K. A. and Stacey, D. 1993. “The marine Enchytraeidae (Oligochaeta, Annelida) of Rottnest Island, Western Australia.”.

On a freshwater species of the genus Sanyuania Zhao and Han, 1980 (Crustacea,Ostracoda, Loxoconchidae) from Thailand,with a discussion on morphological evolution of the freshwater Loxoconchidae

The genus Sanyuania Zhao and Han, 1980 Zhao, G. and Han, D. 1980. “Late Quaternary brackish‐water ostracod faunas from the area to the west of Weishanhu Lake, Jiangsu and their significance.”. In Papers on Marine Micropaleontology, Edited by: Wang, P. 120–129. Beijing (China): Ocean Press.  [Google Scholar] is here transferred from the Cytherideidae to the Loxoconchidae, based on the morphology of valves and soft parts. Sanyuania segersi sp. nov., is described from a freshwater habitat, a river, in Thailand. This is the first record of this genus in Southeast Asia. The new species has a number of remarkable characters distinguishing it from other members in the genus and family: invicidont hinge, spearhead‐like protruding posterior extremity of carapace in dorsal view, subtriangular shape of carapace in lateral view, sieve plate without a central seta (sensillum) and an aberrant chaetotaxy of first and second antennae. The new taxon is compared with other recent freshwater loxoconchids [Cytheromorpha fuscata (Brady, 1869 Brady, G. S. 1869. Contributions to the study of the Entomostraca. IV. Ostracoda from the River Scheldt and the Grecian Archipelago..

The results from both types of analyses are congruent and reveal that Sanyuania segersi sp. nov., Pseudolimnocythere and Loxoconcha are in a more derived clade in the Loxoconchidae and are closely related to each other, whereas Cytheromorpha and Elofsonia are more ancestral.     

A new feather mite genus of the family Psoroptoididae (Acari: Analgoidea) from cassowaries

A new feather mite genus Hexacaudalges gen. n. (Psoroptoididae: Psoroptoidinae) is established based on the type species Megninia casuaricola Proctor, 2001 Proctor, H. C. 2001. Megninia casuaricola sp. n. (Acari: Analgidae), the first feather mite from a cassowary (Aves: Struthioniformes: Casuariidae).. Australian Journal of Entomology, 40: 335–341. [Crossref], [Web of Science ®] , [Google Scholar], which was originally described from the southern cassowary Casuarius casuarius (Struthioniformes: Casuariidae). Morphological peculiarities of this genus, its taxonomic position within the family Psoroptoididae and possible origin are discussed. We also present a clarification of setal nomenclature for this family of mites.     

New species and rediagnosis of Coecobrya (Collembola: Entomobryidae), with a key to the species of the genus

The history of Coecobrya is traced and the genus is redefined. Two new species are described and one known species is redescribed in this paper: Coecobrya lanna sp. nov., Coecobrya tukmeas sp. nov. and Coecobrya aokii (Yoshii, 1995 Yoshii, R. 1995. Notes on Collembola of Vanuatu. Acta Zool Asiae-Orient., 3: 43–50.  [Google Scholar]). Additional details are provided for three other species Coecobrya guanophila Deharveng, 1990 Deharveng, L. 1990.

Complete S-chaetotaxy of the dorsal tergites is illustrated for the first time in the genus. Sinella ciliata Denis, 1932 is synonymized with C. tenebricosa. A key to the world species of Coecobrya is given.     

Revalidation of Hepsetus cuvieri (Castelnau, 1861) (Characiformes: Hepsetidae) from the Quanza,Zambezi and southern part of the Congo ichthyofaunal provinces

Hepsetus cuvieri (Castelnau, 1861 Castelnau, FL. 1861. Mémoire sur les poissons de l'Afrique australe, Paris: Mem Poiss Afr Australe. [Crossref] , [Google Scholar]), originally described from “lac N'gami” (Botswana) and synonymized with H. odoe (Bloch, 1794 Bloch, ME. 1794. Naturgeschichte der ausländischen Fische. Berlin., 8: 1–174.  [Google Scholar]) by Roberts (1984 Roberts, TR. 1984. “Hepsetidae”. In Check-list of the freshwater fishes of Africa (CLOFFA), Edited by: Daget, J, Gosse, JP and Thys van den Audenaerde, DFE. 138–139. Tervuren and Paris: ORSTOM. p.  [Google Scholar]), is revalidated. Hepsetus cuvieri can be readily distinguished from H. odoe based on a lower total number of gill rakers (8–13 versus 14–21); a generally higher number of scales between the dorsal fin and the lateral line (10½–11½ versus 7½–10½) and a higher number of scales between the adipose fin and the lateral line (6½–7½ versus 4½–6½) and other characters. A neotype is designated, as the holotype of this nominal species is apparently lost. Hepsetus cuvieri is restricted to the Quanza, Zambezi ichthyofaunal provinces and the southern part of the Congo Basin, i.e. the Congo ichthyofaunal province.     

A new species of the genus Nanosesarma (Crustacea: Decapoda: Brachyura: Sesarmidae), and redescription of Nanosesarma jousseaumei (Nobili, 1906), including new records from the Persian Gulf

A new species of sesarmid crab from the Persian Gulf, Nanosesarma sarii n. sp. is described. Further, a poorly known species, N. jousseaumei (Nobili, 1906 Nobili, G. 1906. Faune carcinologique de la Mer Rouge. Décapodes et Stomatopodes. Ann Sci Nat, Zool ser. 9., 4(1): 1–347.  [Google Scholar]), is recorded from the Persian Gulf and recognized as a valid species. N. sarii n. sp. is allied to N. minutum (De Man, 1887) and N. jousseaumei (Nobili, 1906) Nobili, G. 1906. Faune carcinologique de la Mer Rouge. Décapodes et Stomatopodes. Ann Sci Nat, Zool ser. 9., 4(1): 1–347.  [Google Scholar], but is easily distinguishable from them through a number of characters, in particular the upper surface of the palm with a longitudinal granular ridge, the upper surface of the movable finger fully covered with tubercles, and abdomen of the male with the sixth segment wide and the seventh segment remarkably elongate. N. jousseaumei differs from its remaining congeners in having a large gap between the cheliped fingers, a large tubercle proximally on the outer surface of the movable finger, and large teeth on the posterior margin of the merus of the walking legs.     

Tardigrades from the Tsinling Mountains,central China with descriptions of two new species of Echiniscidae (Tardigrada)

A checklist of 63 species of tardigrades from the Tsinling Mountains is given in this paper. Thirty‐seven species of tardigrades that had never been found in the Tsinling Mountains were reported here. Twenty of them are new records for the mountains, 15 of them are new records for China, two of them are new to science. Pseudechiniscus pilatoi sp. n. is similar to Pseudechiniscus quadrilobatus Iharos, 1969 Iharos, G. 1969. Einige Angaben zur Tardigradenfauna Vietnams.. Opuscula Zoologica, Budapest, 9(2): 273–277.  [Google Scholar]. It differs from P. quadrilobatus in different cuticular sculpture, in the joints of paired‐plates, near the dorsal median line, uplifting but not protruding backward, and in lacking notches on terminal plate. Echiniscus marleyi sp. n. differs from E. canadensis Murray in having filaments D; it differs from E. mediantus Marcus in lacking filaments C but in having filaments D; it differs from E. spinulosus (Doyère) in lacking teeth B, C, E, and in having filaments D instead of teeth D.     

Revision of Pilargis de Saint‐Joseph, 1899 (Annelida,Polychaeta, Pilargidae)

Two species (P. verrucosa and P. berkeleyae) have been recorded from widespread localities. However, no comparison with type material has been done, and there might be some different forms under the same name. We have reviewed all the available type material in order to clarify the taxonomy of this group. A critical analysis of morphological features and a standardization of their structure and variability have been attempted. Six species are redescribed, one species is characterized after published accounts, and one subspecies is elevated to species. Four are described as new: Pilargis angeli n. sp., P. cholae n. sp., P. rozbaczyloi n. sp., and P. wolfi n. sp. Three others based on damaged material are briefly characterized. A key for Pilargis species is included.

The junior homonym Burckhardtia Brown and Hodkinson nec Frech is replaced by Hodkinsonia nom. n. The introduction of the two generic replacement names necessitates two new combinations. Four species are described as new. Keys for the identification of adults and the last instar larva are provided along with species diagnoses and illustrations of taxonomically relevant structures. The galls and known biological features are briefly discussed for each species and the phylogenetic relationships among the species are analysed. Baccharopelma spp. are monophagous on Baccharis spp. (Asteraceae) on which they induce galls. The temperate South American genus has one species restricted to Chile, three to Brazil and one occurring in Argentina, Brazil and Paraguay.     

Revision of the hirsuticornis‐like species of Macrothrix Baird, 1843 (Cladocera: Anomopoda: Macrothricidae) from Subantarctic and temperate regions of the southern hemisphere

The aim of this paper is to revise populations of Macrothrix cf. hirsuticornis (Cladocera: Anomopoda: Macrothricidae) from different regions of the southern hemisphere. It is demonstrated that M. hirsuticornis Norman and Brady, 1867 Norman, A. M. and Brady, G. S. 1867.

All populations in the southernmost portion of continental South America, Tierra del Fuego, Falklands, South Georgia, South Orkney Islands, and on the Antarctic Peninsula belong to M. oviformis Ekman, 1900 Ekman, S. 1900.

[Crossref] , [Google Scholar], previously known only from Tasmania, is found on Macquarie Island too. Differences between species from the southern hemisphere and Palaearctic M. hirsuticornis are summarized. It is demonstrated that characters of the general body shape (i.e. presence of a hood or a tooth on posterior head border) have a limited value for the systematics of Macrothrix. In contrast, some fine details, mostly missed by previous authors, are valuable for species discrimination. The present study increases the number of species recorded from the Antarctic‐Subantarctic region. Probably, the current pattern of Macrothrix distribution results from a disruption of a pan‐continental (early Mesozoic?) species complex.
