Inventory of the Carabid Beetle Fauna of the Gaoligong Mountains, Western Yunnan Province, China: Species of the Tribe Omophronini (Coleoptera: Carabidae), with a Key and Review for All Species Recorded from China

摘要

Our study of 343 specimens of omophronine carabid beetles collected during a ten-year biodiversity inventory project in the Gaoligong Shan region of western Yunnan Province, China, recognized three different species of genus Omophron Latreille, all previously described. We present a key for identification of adults of these species, as well as nomenclatural data, diagnoses, illustrations of dorsal habitus and male and female genitalia and information about geographical, altitudinal and habitat distributions within the study area and overall geographical distribution for each species. Distributions of the species within the study area are compared and broader geographical range patterns are characterized. We also present a review of the nine Omophron species now known to occur in China, provide a new key for identification of the Chinese species and summarize the known geographical ranges of each of these species. Two new synonymies are proposed (O. parvum Tian & Deuve, 2000 = O. gemmeum Andrewes, 1921; and O. yunnanense Tian & Deuve, 2000 = O. stictum Andrewes, 1933) and a lectotype is designated for O. stictum Andrewes.
