The new species, Gonatodes timidus sp. nov., is known so far from the type locality only, at ca. 210 m elevation. The new taxon is mainly distinguished from all known congeners by the following combination of characters: moderate body size, absence of a clearly differentiated elongate supraciliary spine, absence of clusters of distinctly enlarged conical scales on sides, escutcheon scales on posterior belly and ventral surfaces of thighs in males evident, three to four lateral rows of scales on distal part of fingers and toes, medial subcaudal scales distinctly differentiated from adjacent scales on non-regenerated tail ( in a 1' 1 '' sequence), and obvious sexual dichromatism, the males having the upper surface of the head black with bluish white to vivid yellow irregular stripes and blotches.
查看更多>>摘要：A new sparid species, Polysteganus mascarenensis n. sp. (Perciformes; Sparidae) is described on the basis of three type specimens (578-600 mm SL) from the Mascarene Islands, Indian Ocean. The species differs from the four known congeners of Polysteganus in having the following combination of characters: body moderately slender (depth 39% SL), scale rows between 10th dorsal-fin spine base and lateral line 6 Vi, fewer lateral line scales 51-54, snout broad, its length 2.2-2.3 times orbit diameter in adults, inter-orbital area of adults with a bony bulge before and above eye (hyperostosis of frontal bones), forming a low median ridge; mouth large, jaws robust, especially upper jaw, caudal fin emarginate (nearly truncate if widely spread), head, body, and all fins generally reddish orange, no dark blotch or rows of small spots along scale rows on the body. The status and identification of congeneric nominal species are discussed, and a key to the species of Polysteganus is provided.
查看更多>>摘要：A new species of the previously monotypic Malagasy pachybolid genus Zehntnerobolus Wesener, 2009, Z. hoffmani new species, is described. The diagnosis of the genus Zehntnerobolus is updated and new characters of potential phylogenetic importance for the classification of Malagasy Spirobolida are described. The here described specimens are the first known representatives of Zehntnerobolus collected since 1900. The late discovery of another Zehntnerobolus is a clear indication of how little we know about the soil arthropod macrofauna of Madagascar. Particularly the eastern rainforest region and the north of Madagascar are still underexplored. The specimens were collected in the eastern montane rainforest more than 380 km south of the known distribution of the other Zehntnerobolus species. The collection method used, as well as morphological parameters of Zehntnerobolus indicate that its species live in the leaf litter of Malagasy rainforests.
查看更多>>摘要：Three new species of Sosippinae from Argentina are described; one new species of Hippasella Mello-Leitao, 1944, H. alhue sp. nov., from temperate Andean forests in the Argentinean provinces of Neuquen and Rio Negro and two new species of Aglaoctenus Tullgren, 1905, A. yacytata sp. nov., from the rainforests in Misiones province, and A. puyen sp. nov., from temperate Andean forests in Rio Negro province. Aglaoctenus oblongus (C. L. Koch, 1847) is recorded for first time in Entre Rios province and new records for Buenos Aires province (Argentina) and Montevideo (Uruguay) are provided. The distribution of A. lagotis (Holmberg, 1876) is updated with first time records for the Argentinean provinces of Jujuy, Salta, Chaco, Formosa, La Rioja, Tucuman, Santiago del Estero, San Luis and Entre Rios, new localities in the provinces of Misiones, Corrientes, Santa Fe and Cordoba.

Two new species are described: Hydrodroma bruneiensis (Hydrodromidae) and Litarachna bruneiensis (Pontarachnidae); Limnesia lembangensis Piersig, 1906 and Arrenurusbihamatus K. Viets, 1935, are reported for the first time from Brunei Darussalam. The water mite fauna of Borneo now tallies 41 species.

Since then, no other specimen of the species was mentioned in the literature, and the species was only listed in catalogues, eventually mentioned and treated as a "poorly known" species, or even omitted in checklists of fishes from Venezuela. During a visit to the fish collection at the Naturhistorisches Museum at Vienna (NMW) to examine all the type specimens of Leporinus, we were able to study the holotype of Leporinus latofasciatus and recognize that the specimen corresponds to the species described by Myers and Fernandez-Yepez (in Myers, 1950) as Synaptolaemus cingulatus. Thus, the latter is a junior synonym ofLeporinus latofasciatus and, based on that, Synaptolaemus latofasciatus (Steindachner, 1910) should be the name applied for this taxon, as a new combination. Herein new data on the holotype of Synaptolaemus latofasciatus are presented and compared with previously data from other authors. In addition, illustrations of live specimens are presented as well as new distribution records for the species.
查看更多>>摘要：The pontoniine shrimp genus Ancylomenes Okuno & Bruce, 2009 now includes 17 Indo-West Pacific species (Okuno & Bruce 2009). With a few exceptions, such as A. aesopius (Bate, 1863) and A. longicarpus (Bruce & Svoboda, 1983), these present a highly consistent morphology, differing at species level principally in details of the rostrum, third abdominal somite, ophthalmic process, dentition of the second pereiopod chelae, and ambulatory propods and dactyls. This consistency renders detailed descriptionsrepetitive and largely redundant. Some specimens of Ancylomenes collected in the northern Kimberley region of Western Australia during the Western Australian Museum 2010 Kimberley Survey, were found to belong to an undescribed species, which is now described and illustrated. Specimens are deposited in the collections of the Western Australian Museum, Perth (WAM) and the Queensland Museum, Brisbane (QM).
