The genus Anommatium FOERSTER is revised, taxonomic adult characters are discussed and evaluated. The assumed synonymy of Somaroa JANSSON to Anommatium FOERSTER is confirmed and Somaroa myrmicaria Jansson, 1956 is reduced to a subspecies of Anommatium ashmeadi MAYR, 1904. Anommatium stramineum KIEFFER, 1908 (1907 — 1911) is a new synonym of Anommatium ashmeadi MAYR. The male is conclusively recognized and appropriately associated based on inferred synapomorphies. The single European species is split geographically into two subspecies — Anommatium ashmeadi ashmeadi MAYR and Anommatium ashmeadi myrmicarium (JANSSON).
