查看更多>>摘要：Recent efforts with Malaise trap sampling in Serra dos Orgaos and Itatiaia, in Brazil, allowed us to identify and describe three new species from the first locality: Hylotribus humeralis sp. nov., H. nanico sp. nov. and H. queirozi sp. nov. New records of H. plaumanni Queiroz & Mermudes, 2014 for both localities and H. sublimis Queiroz & Mermudes, 2014 for the latter are also presented. We also describe morphological variability including aptery and microptery, and male genitalia, for H. plaumanni. We produce a new key to the species and discuss the species relationships and wing variation for the genus.
查看更多>>摘要：A new species of the pilumnid crab genus Pilumnus Leach, 1815, P. mantelattoi n. sp., is described and illustrated on the basis of a single ovigerous female specimen from Belize, bordering the northwestern Caribbean Sea. The holotype, an ovigerous female, was taken from an epifaunal accumulation of sponges, ascidians, and hydroids on red mangrove roots suspended in the water column. Superficially resembling Pilumnus floridanus Stimpson, 1871, with which it occurs sympatrically, it is distinguished from this and all other known western Atlantic species on the basis of both morphology and molecular markers.
查看更多>>摘要：We describe a new species of Zhangixalus from southern Yunnan of China, Vietnam, and Thailand based on morphological and molecular evidence. The new species had been confused with Zhangixalus smaragdinus (Blyth, 1852) in the past. Zhangixalus pachvproctus sp. nov. can be distinguished from Z. smaragdinus morphologically by the protruding vent in adult males, large thick grey reticular mottles below the white stripe on flank, more oblique snout in profile and wider head, longer snout, greater internarial distance, larger tympanum and longer hindlimb. The new species can be distinguished from other species of Zhangixalus with green dorsum by the following combination of characters: body size larger (SVL of adult males: 74.2-83.3 mm; SVL of adult female: 102.4 mm); dorsum smooth; narrow white stripes along edge of the lower jaw, body sides, outer side of limbs and above the vent; absence of brown bands on canthus rostralis, upper eyelid and supratympanic fold; webbing between fingers and toes complete except between the first two fingers; and internal single subgular vocal sac. Phylogeny based on comparison of 16S rRNA sequences suggests that the new species is the sister taxon to Z. smaragdinus and the two species differ by 7.63% in the uncorrected pairwise distance of 16S sequences.

(Myrtaceae) from Atlantic Forest areas of Sao Paulo State, Brazil. Metatarsonemus Attiah is reinstated as a genus based on apomorphic attributes which are recovered through examination of specimens of the new species herein described, in addition to specimens of M. simplicissimus Attiah and M. megasolenidii Lofego & Ochoa. A cladistic analysis tentatively indicates that the Metatarsonemus lineage is sister group to a lineage comprising the genera complex Daidalotarsonemus+Ceratotarsonemus+Excelsotarsonemus in sharing four homoplasious apomorphic attributes. A dichotomous key is provided for identification of the species of this genus described so far.
查看更多>>摘要：Seven loaches of Homatula are distributed in a narrow geographical area between the upper Black River (or Song Da in Vietnam, that is a major tributary of the Red River, including the tributaries Lixian-jiang and Tengtiao-jiang in Yunnan, China) and the upper Salween River drainage (including tributaries of the Nu-Jiang and Nanding-he, the latter is a major tributary of the Salween River in Yunnan, China). These seven species are distinguished from other Homatula by the combination of having the body densely-scaled, the lateral line complete, and a short adipose crest along the dorsal midlinc of the caudal peduncle that does not mach the posterior end of anal-fin base or does not extend beyond the middle of the anal-fin base. Based on a comparison with the described species of the densely-scaled group of Homatula, we can confirm that the specimens collected from the Nu Jiang drainage in western Yunnan are different from known species and arc described herein as Homatula anteridorsalis sp. nov., Homatula cryptoclathrata sp. nov., and Homatula nigra sp. nov.
查看更多>>摘要：A morphological and genetic study of both newly collected and museum specimens of the cast Australian freshwater shrimp genus Australatya indicates two genotypes and three morphotypes are present. One genotype and morphotype were of the known species, Australatya striolata (McCulloch & McNeill 1923). The second genotype, comprising two morphotypes, is now described as a new species, Australatya hawkei sp. nov.. All Australian Australatya species and morphotypes currently have allopatric distributions. Australatya striolata is widespread along the south-eastern Australian seaboard. from Genoa River in Victoria to the Sunshine Coast in Queensland. The 'southern' morphotype of Australatya hawkei sp. nov. occurs in north Queensland, from near Mackay to about Cooktown, and its 'northern' morphotype is found on Cape York Peninsula, north from about Coen to the Iron Range, just north of Lockhart River. The once monotypic genus now includes two Australian species, Australatya striolata and A. hawkei sp. nov., and a third, A. obscura, recently described from Japan, Taiwan, and the Philippines.

(State of Rio de Janeiro), and A. pinna sp. nov. (State of Mato Grosso). The first two species are from the Atlantic Forest, whereas the third is from the Amazon Forest. Cicada unifasciata Fabricius, 1803 is redescribed and transferred to Amblyscarta based on specimens from Guyana and northern Brazil (Amazon Forest). This Fabrician species is the type of the monobasic genus Strictogonia Melichar, 1926, which is thus considered a junior synonym of Amblyscarta. A diagnosis of Amblyscarta is added, as well as brief notes on the phenology of A. elianeae. This paper provides the first detailed descriptions and illustrations of the female terminalia of Amblyscarta species.

Between 2012 and 2016, a biodiversity study of Diptera was conducted at Jazan, Asir, and Najran in south-western Saudi Arabia, at 22 sites, was performed mainly using Malaise traps and sweep nets. In this study, 43 known species of Ephydridae were identified, 37 of them for the first time from southwestern Saudi Arabia and 16 from Arabian Peninsula. This brings the total number of Ephydridae species in Saudi Arabia to 49 (including previous records). 'There were a further four species, which could not be identified authoritatively to species level. A list of all species of Ephydridae recorded from Saudi Arabia is appended. Images of thirty-two species are presented. The species recorded in this study are more Palaearctic in origin as compared to other regions. Biological information (where known) and world-wide distribution are included. This study has added new records to the Saudi Arabian checklist of Ephydridae, which will provide the basis for systematic studies and fauna analyses of future work on the family. The need for further field and laboratory work and surveillance is highlighted.

查看更多>>摘要：The California horn snail, Cerithideopsis californica, lives in estuarine habitats from California (USA) in North America to Piura (Peru) in South America. Throughout this range, the snail serves as first intermediate host for a diverse guild of digenean trematodes. These parasites are used in teaching laboratories, and have been subject to a large amount of taxonomic, biological, evolutionary, and ecological research. Despite the abundance of research on these trematodes, we lack a satisfactory guide to these parasites. This manuscript treats the 19 trematode species that we are currently able to distinguish morphologically. I provide taxonomic affinities, information on second intermediate host use, an identification key focused on cercaria traits, information and a key for regressed infections lacking cercariae, information on early infections, and species accounts. The species accounts present photographs, additional diagnostic information, taxonomic notes, information concerning cryptic species, and connections to relevant literature. The primary aim of this manuscript is to facilitate research on this trematode guild by serving as an identification tool, and by providing background information, including highlighting gaps in our knowledge.
