Objective To investigate the taxonomy of Lepidoptera insects of the family Drepanidae in Linzhi City, Xizang, clarify the species composition and distribution of Drepanidae in this region, and enrich regional species diversity, thereby providing basic data for studying the evolution and phylogeny of Drepanidae insects.
Method Species identification and classification were conducted using traditional taxonomic methods based on adult morphological characteristics as well as the external genitalia of both males and females.
Results Two species were recorded from China for the first time: Agnidra Moore, 1868, Agnidra vinacea Moore, 1879 and Agnidra corticata Warren, 1922.
Conclusion The external morphology of adults, male and female genitalia and other characteristics of the two species were described in detail. Illustration of adults and genitalia, along with information on their geographical distribution, were provided. These findings enrich the species of Drepanidae in this area, which is of great significance to the ecological environment work, and provides a basis for the sustainable utilization of Drepanidae insect resources and the prevention and control of agricultural and forestry pests in Xizang. All examined specimens are deposited in the Institute of Plateau Ecology, Xizang Agricultural and Animal Husbandry University.
