Dolichoderus pinguis


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.
