Faunistic investigation of Tachinidae in Helan Mountain National Nature Reserve, China
Objective To investigate the biodiversity and fauna of Tachinidae in Helan Mountain National Nature Reserve of China. Methods Morphology taxonomy and zoogeography principles and methods were applied in this study. Results Fifty -seven specie, 35 genera IS tribes and 4 subfamilies were identified. Among these tachinidae, one genus was newly recurded in China: (Elamya Robineau-Desvoidy, 1830); three species were newly recorded in China: Elomya lateratis (Meigen, 1824), Lydella ripae (Brischke, 1885), Phonomyia atypical Mesnil, 1963; two 9pecies are recorded as endemic in China: Peleteria flavobasicosta, Tachina genurufa; fourteen species were newly recorded of Inner Mongolia. Conclusion Because Helan Mountain was formed later than the time of divergence of tachinid flies, the Helan Mountain did not prevent the mutual diffusion of Palaearctic and Oriental tachinid flies. Therefore, the tachinid flies of Helan Mountain are dominated by Palaearctic and Oriental Tachinidae, especially tachinid flies that were distributed in both the Palaearctic and Oriental regions. All of the specimens are deposited in the Insect Collection, Shenyang Normal University, China.
