Abstract

The Chinese species of the highland weevil genus Pachynotus is revised, including a single known species, P. lampoglobus Chao & Y.-Q. Chen, 1980, and the descriptions of two new species, P. pilosus sp. nov. and P. arcuatus sp. nov. All Chinese Pachynotus species occur in Xizang (Tibet), China, and a key to these species is presented. Additionally, the COI sequences of two species, P. lampoglobus and P. pilosus sp. nov., are provided, with details of the genetic distance.
