ABSTRACT. A new species, Lithobius (Monotarsobius) tanagolus sp.n., is described from southern Siberia, Russia. The new species shows no apomorphies, but is defined by a unique combination of characters. It seems to be the closest to L. (M.) holstii (Pocock, 1895), but the female of L. tanagolus sp.n. differs well from that of L. holstii by the presence of a distodorsal spine on the first gonopodal segment and the armament of the second and third gonopodal segments. A refined diagnosis of L. (M.) holstii is given and its distribution mapped.
