Gonatopodinae of the C. G. Thomson collection in the Ent. Mus., Zoological Institute, Lund (Sweden), and in the Naturhistoriska Riksmuseet, Stockholm (Sweden), are revised. The supposed synonymy of Gonatopus pílosus Thomson, 1860, with Gonatopus sepsoides Westwood, 1833, seems reasonable. The following synonymy is proposed: Gonatopus flavicornis Thomson, 1860=Neogonatopus distinguendus (Kieffer, 1905); flavicomis Thomson falls into synonymy because it is preoccupied by Gonatopus flavicornis Dalman, 1818 (now Anteon flavicorne). Lectotypes of Gonatopus pilosus and Gonatopus flavicornis are designated.
