Abstract
The pauropod family Eurypauropodidae Ryder, 1879 is recorded from Tibet, China for the first time. In this study, a new species Samarangopus zhongisp. nov. is described and illustrated from Motuo County, southeastern Tibet of China. It is distinguished from other species in this genus by having one pair of spiniform appendages on the sternum of the last trunk segment, 28–34 marginal protuberances on tergite I, the distal quarter of bothriotricha T3 golf-club-shaped, and the leaf-shaped seta st on tergum of pygidium. In addition, Samarangopus canalis Scheller, 2009 is newly recorded from China.
