Formica glabrella Nylander 1849 [type investigation]

The species has been described from Cherkassy / Ukraine. Investigated were two type workers on two different pins, both deposited in ZM Helsinki. One worker labelled “Tscherkassk”, “Motschoulsky”, “ Coll. Nyland. ”, “Motsch. 23”, “Spec. type No. 5092 Formica glabrella Nyl. ” was fixed by present designation as lectotype. The type series is allocated to the T. glabrella cluster with p= 0.9998 in a wild-card run of a LDA considering 12 morphometric characters ( Tab. 1). The paratype worker on the other pin had the same labelling except for “Spec. type No. 5093 Formica glabrella Nyl. ”. It belongs to Tapinoma subboreale (see there) .
