Eoformica expectans (Theobald, 1937) comb. nov.

Gesomyrmex expectans Theobald , 1937, p. 210-211, pl. iV, fig. 13; pi. XiV, fig. 21 [[male]]); Burnham, 1978, p.114; Bolton, 1995, p. 207.

Comments. Described from one imprint from Kleinkembs, Haut-Rhin, France (early Oligocene). The specimen has a small rounded head with comparative small eyes and a comparative long scape, so it cannot be Gesomyrmex . Forewings are not preserved. The specimen is assigned to the formal genus (morphogenus) Eoformica Cockerell, 1921, which includes poorly preserved wingless imprints of ants in which the waist is one-segmented and narrowly attached to the gaster and the gaster lacks a constriction between the first and second segments. Eoformica Cockerell, 1921 includes three species: E. pinguis (Scudder, 1877), E. magna Dlussky & Rasnitsyn , 2003 and E. globularis Dlussky & Rasnitsyn , 2003. Eoformica expectans (Theobald) differs from another all other species included in this genus (Dlussky & Rasnitsyn, 2003) by its body proportions.

Comments. Described from two imprints from Kleinkembs, Haut-Rhin, France (early Oligocene), both without head and wing venation. The poor preservation of these imprints does not permit the assignment of these ants to any living or fossil genus, so we propose to regard these specimens as Formicidae incertae sedis.
