ABSTRACT. A new lithobiid species, Bothropolys obtusodentatus sp.n., is described and illustrated from the Yintiaoling National Nature Reserve in Wuxi County, Chongqing Municipality, southwestern China. The new species is primarily compared with B. shansiensis Takakuwa, 1949, from the Hebei and Shanxi provinces, P.R. China, B. yoshidai Takakuwa, 1939, from the Hubei and Fujian provinces, China, as well as Japan and North Korea, and B. rugosus (Meinert, 1872), widely distributed in China, but it can easily be distinguished by its porodonts lying posterolateral and adjacent to the lateralmost tooth, Tömösváry’s organ approximately equal to the adjoining ocelli, TT 1, 2, 3, 4 being devoid of wrinkles, the posterior angles of TT 4, 6 and 7 rounded, the lack of posterior accessory spurs on legs 14, and the first article of the female gonopods showing 4+4 small coniform spurs.
