Dlussky, G. M., Rasnitsyn, A. P. & Perfilieva, K. S., 2015, The Ants (Hymenoptera: Formicidae) of Bol’shaya Svetlovodnaya (Late Eocene of Sikhote-Alin, Russian Far East), Caucasian Entomological Bulletin 11 (1), pp. 131-152 : 135

Dolichoderus pinguis sp.n.

( Fig. 5)

Material. Holotype PIN 3429/1134, male. Biamo.

Description. Male. Body length 6.3 mm. Head wider than long, with convex occipital margin. Eye large, ovate, 0.5 times as long as head. Scutum elongate, nearly twice as long as scutellum. Propodeum with weakly convex dorsum and concave declivity. Petiole nodiform with short peduncle.

Measurements of holotype, mm: AL 2.3; HL 1; ED 0.5; SctL1.3; SctlL0.7.

Comparison. All fossil congeners being described after female sex, a reliable comparison of the only available male is impossible. A peculiar structure of petiole of the new species is comparable to that of Dolichoderus kutscheri Dlussky, 2008 from the Late Eocene Bitterfeld amber.

Etymology. Pinguis is the Latin for fat.
