Eoformica expectans
status

comb. nov.

Eoformica expectans  HNS  (Theobald, 1937) comb. nov.

Gesomyrmex expectans Theobald  HNS  , 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  HNS  . Forewings are not preserved. The specimen is assigned to the formal genus (morphogenus) Eoformica  HNS  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  HNS  Cockerell, 1921 includes three species: E. pinguis  HNS  (Scudder, 1877), E. magna Dlussky & Rasnitsyn  HNS  , 2003 and E. globularis Dlussky & Rasnitsyn  HNS  , 2003. Eoformica expectans (Theobald)  HNS  differs from another all other species included in this genus (Dlussky & Rasnitsyn, 2003) by its body proportions.

Formicidae (incertae sedis) miegi Theobald  HNS  , 1937 comb. nov.

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.
