First and second instar larvae and adults of a new Homidia species (Collembola, Entomobryidae) recorded from Xizang Autonomous Region with three new records
Three new recorded species of genus Homidia were collected from Xizang Autonomous Region, China, in the present paper. Among them, a new species, Homidia breviseta Pan, sp. nov., is included in the present paper. This new species can be identified by having a single uninterrupted dark band on central thoracic segment III; 14 macrochaetae on abdominal segment I and seven on the posterior central abdominal segment IV (half segment); and very short bothriotricha on abdominal segments II–IV. It can be easily discriminated from similar species of Homidia by its colour pattern, chaetotaxy of the labium, and abdominal segments I and IV. The chaetotaxy of the first and second instar larvae of this new species and a key to four species of genus Homidia from Xizang are also provided.
