Abstract

A new species of the genus Neopseustis Meyrick, 1909, Neopseustis chentangensis S.Y. Huang & Chen sp. nov., which was confirmed by both morphological and molecular methods, is described from Xizang, China. This is currently the westernmost species in Asia of the primitive lepidopteran family Neopseustidae. The new species is externally reminiscent of N. moxiensis Chen & Owada, 2009; however, it can be easily distinguished from the latter by comparison of the male genitalia and is further distinguished by the large genetic distance in DNA barcodes (COI). The adult and genitalia of the new and similar species have been illustrated. Utilizing our new data, a new classification of the genus is provided, with its members subdivided into four species groups: the meyricki-group, the moxiensis-group, the bicornuta-group, and the chentangensis-group, which are supported by both molecular and morphological evidence. A checklist of the genus and a key to the species groups are also provided.
