Tapinoma collina Foerster 1850 [zoogeography and original description]

The species has been described from near Königswinter and Boppard / Germany (“ Siebengebirge und bei Boppard auf Bergwiesen”). Types are obviously lost. According to zoogeography and the situation in the 19 th century without invasive species present, only two species may have occurred in the terra typica: T. erraticum and T. subboreale . As Foerster (1850, p. 43–44) described the anteromedian clypeus in both workers and gynes to be deeply and almost circularly excavated (“Clypeus in der Mitte tief und fast rundlich ausgeschnitten”), a conclusion on junior synonymy with T. erraticum is reasonable—at least, due to the abscence of types, no counterevidence can be given. Alternatively this taxon could be placed under Incertae Sedis.
