ABSTRACT. A new lithobiid species, Lithobius (Monotarsobius) aterrimus sp.n., is described from several provinces of mainland China. Morphologically, the new species seems to be extremely close to Lithobius (Monotarsobius) femoratus Pei, Ma, Liu, Lu et Liang, 2021 from Hebei Province, China, but it can easily be distinguished by its moderately wide central longitudinal groove on the dorsal side of the tibia of male legs 15, and the apex is widened and raised to form an obvious protuberance, 8–10 ocelli on each side, the presence of DaC spine on legs 13, 14 and 15, and a bidentate apical claw of the third article of the female gonopods. Based on adult specimens, a key to all 14 species of the subgenus Monotarsobius known to occur in China is presented, with a map showing the distribution of the new species.
