New data on the occurrence of several ant species, previously not known from Lower Silesia or other regions of the country, is given. Among these, there are several common species that were already expected to occur in Lower Silesia. The change of status of the names Formica glauca, F. lusatica and Tapinoma ambiguum is explained in the light of recent synonymies of lusatica under Formica clara FOREL, 1886 and ambiguum under Tapinoma subboreale SEIFERT, 2012.
