Gesomyrmex macrops View in CoL sp. n.
( Fig. 13)
Material. Holotype PIN 3429/1162, incomplete dorsal print of gyne.
Description. Gyne. Body length 9.7 mm. Head subrectangular, about 1.4 times longer than wide, with feebly concave sides, convex occipital margin and rounded occipital corners. Anterior clypeal margin projected as small rounded lobe. Eyes ovate, large: head about 3 times longer than maximum eye diameter. Scape does not reach posterior margin of eye, head about 3times longer than scape. Mandibles triangular with 4teeth on the masticatory margin. Scutum nearly as long as scutellum. Petiole low, about as long as high. Legs comparatively short and thick. Gaster ovate. Wings not preserved.
Measurements of holotype, mm: AL 2.7; HL 1.7; HW 1.25; SL0.55; ED0.55.
Comparison. Differs from other species of Svetlovodnaya by large eyes. Gesomyrmex germanicus (Eckfeld, Germany, Middle Eocene) and G.pulcher (Grube Messel, Germany, Middle Eocene) also have large eyes (2.6–3times less than head length) but they differ from the new species by the form of head. Gesomyrmex germanicus has head with convex sides and G.pulcher has head with distinctively concave posterior margin. Also G.pulcher is less (body length 4.8mm).
Etymology. Macrops is the Latin for “with large eyes”.
