Solenopsis flavidula (Nylander, 1849)

Myrmica flavidula Nylander, 1849. [type investigation]

Notes.

The species was described from the region of the Don river, southern Russia. Seven syntypes from FMNH Helsinki were investigated: two workers on one pin, "Ross. merid.", “Motchoulsky”, "Coll. Nylandr.", "Mus. Zool. H: fors Spec. typ. No. 5107 Myrmica flavidula Nyl."; five workers on three pins with the same labels as the previous, but type Nos. 5107, 5108, and 5109. Two type specimens allowed the recording of the full set of 18 characters in the measuring system of BS. The synonymy was confirmed by a wild-card run in a LDA which allocated the two type specimens with p = 0.9996 to the S. fugax cluster.
