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.
Two new species of hangingflies, Terrobittacus rostratus sp. nov. and Terrobittacus angustus sp. nov., are described and illustrated from Yunnan, southwestern China, increasing the species number of Terrobittacus Tan & Hua, 2009 to six. Terrobittacus rostratus sp. nov. differs from its congeners by wings devoid of markings and epandrial appendages slightly longer than half the length of the gonocoxites. Terrobittacus angustus sp. nov. can be recognized by wing markings along R5 distally. A key to species of the genus is updated to include the two new species.
Three new species of the genus Mimetus Hentz, 1832 are described and named as M. bucerus sp. nov. (♂), M. lingbaoshanensis sp. nov. (♂♀) and M. yinae sp. nov. (♂♀). Detailed morphological descriptions, photos of the body and copulatory organs, line drawings of copulatory organs, as well as the distribution maps are provided.
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.
The current knowledge of the scorpionfly genus Dicerapanorpa Zhong & Hua, 2013 is taxonomically reviewed. Two new species of Dicerapanorpa are described and illustrated, increasing the species number of this genus to 20. Dicerapanorpa bifurcata sp. nov. from the Minshan Mountains, Sichuan Province, is characterized by the absence of the paramere basal branch and the elongated mesal branch in males, and the medigynium having a short basal stalk in females. Dicerapanorpa zhengkuni sp. nov. from the Wuling and Miaoling Mountains, Guizhou Province, is distinguishable by the greatly elongated hypovalves, the very short basal branch of the paramere, and the dorsomedially curved lateral branch in males, and the rounded main plate of the medigynium in females. An updated key to species of Dicerapanorpa is presented.
Representatives of the subgenus Helochares (s. str.) Mulsant, 1844 of China are revised. One new species, H. (s. str.) songi sp. nov., is described from Guangxi, China. All species known from China are redescribed. A diagnosis and a differential diagnosis are provided for each species. Helochares
fuliginosus d’Orchymont, 1932 is recorded for the first time from China and Cambodia. Additional distribution records of H. atropiceus Régimbart, 1903 and H. pallens (MacLeay, 1825) are provided from China. The habitus and aedeagus of all species are illustrated, and a key for the identification of Chinese species of the subgenus is provided.
Twenty species of the genus Chilocorus Leach, 1815 currently known from China are recorded, including two new species described here: C. nigricaeruleus Li & Wang sp. nov. and C. strenotubus Li & Wang sp. nov. Diagnoses and detailed descriptions of the new species are given. Each species is illustrated in detail, including genitalia. Distribution maps, a key to the Chinese species and a world checklist of Chilocorus are given.
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.
