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.pilosussp. nov. and P.arcuatussp. 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.pilosussp. nov., are provided, with details of the genetic distance.

Keywords: COI; Curculionidae; Pachynotus; Xizang; key; new species.
