A new species of the basal araneomorph spider genus Ectatosticta (Araneae, Hypochilidae) from China
(2009)
The hypochilid spider Ectatosticta davidi (Simon) is redescribed on the basis of adults from Mt. Taibaishan in Shaanxi Province, China; the specimens from Qinghai Province previously identified as E. davidi by most modern authors belong to a new species described as E. deltshevi. Keywords: Araneae, Araneomorphae, Hypochilidae, Ectatosticta, China
A three week trip to Hainan and Guangdong provinces was conducted between 26 May and 11 June 2014, sampling odonates within the vicinity of Diaoluoshan National Nature Reserve, Shuimanxing Village (both Hainan Province) and Nankunshan Nature Reserve (Guangdong Province). Additionally, Cordero and Zhang collected at Shuimanxing Village between 13 and 23 June. A total of 103 species in 78 genera were found for Hainan Province and 51 species in 42 genera in Guangdong Province. Lists of all species by locality, photographs of live specimens, are presented to facilitate identification to other collectors.
Four new species of the genus Willowsia Shoebotham, 1917 are described from China: W. fascia Zhang & Pan sp. nov., W. pseudoplatani Zhang & Pan sp. nov., W. pseudobuskii sp. nov., and W. similis sp. nov. Willowsia qui Zhang, Chen & Deharveng, 2011 is re-described based on types and fresh material. All five species possess the pointed body scales with basal ribs longer than distal ones. These scales are absent on antennae, legs, ventral tube and furca. Colour pattern and dorsal chaetotaxy are the main diagnostic characters for these species. DNA barcodes of four species are also provided, with genetic distances compared. A key to the Willowsia species having scales of the long basal rib type is given.
The new subgenus Maculergithus subgen. nov. is established to accommodate two new species of the genus Gergithus Stål, 1870 (Issinae, Hemisphaeriini): G. (Maculergithus) tamdao subgen. et sp. nov. and G. (Maculergithus) luteomaculatus subgen. et sp. nov. from Tam Dao National Park in North Vietnam. Two more species from Hainan, China, G. multipunctatus Che, Zhang & Wang, 2007 and G. nonomaculatus Meng & Wang, 2012 are also placed in Maculergithus subgen. nov. A fifth species from Hainan, yet undescribed and erroneously identified as G. multipunctatus in recent papers also belongs to this new subgenus. Illustrations of habitus, morphological details and male genitalia together with a distribution map and an identification key to the species of Maculergithus subgen. nov. are provided. Four species of the genus Gergithus are now recorded in Vietnam. A rectificative note on the misinterpretation of G. multipunctatus in recent publications on Issidae is also provided.
Six new species of false click beetle (Coleoptera: Eucnemidae) are described. These new species are: Fornax dixiensis sp. nov. (Florida, USA), Dromaeolus comayaguiensis sp. nov. (Honduras), Asiocnemis bicolor sp. nov. (Ecuador), Miruantennus chinensis sp. nov. (Yunnan prov., China), Miruantennus cuneiformis sp. nov. (Malaysia) and Nematodes africanus sp. nov. (Côte d’Ivoire). Identifi cation keys are provided for species of Fornax in the Nearctic ecozone and Miruantennus in the Palearctic and Indo-Malayan ecozones. A new key to include all the genera within the tribe Nematodini Leiler is also provided.
Between 2009 and 2016, a total of 174 Odonata species (Tab. 1) have been recorded in the Dehong Dai and Jingpo Autonomous Prefecture, China. 21 of these species are new records for China, and additional 26 taxa have to be described as new to science. Brief comments on selected species refer to morphological characters, distribution and seasonality.
