S. text Caucasian Entomological Bulletin 2015 11 1 131 152 journal article Pachycondyla aberrans sp. n. ( Fig. 23 ) Material. Holotype PIN 3429/104, lateral imprint of male or gyne without head and top of gaster. Description. Male or gyne. Judging by the remained parts the length of a body ca. 6–7 mm. Parapsidal furrows present. Propodeum angulated in side view. Petiole with high node, rounded in side view. Forewing with closed cells 1+2r, 3r, mcu and2cua. Closed cell rm is absent (rs-m reduced). Cell3r 4.7times as long as wide. Cell mcu pentagonal, longer than wide. 1M nearly 3times as long as1RS. The meeting of crossvein cu-a and M+Cu is proximal to the 1M and 1Cu fork, being separated from it by two widths of vein. Figs 22–26.

Рис. 22–26. Виды родов Pachycondyla , Proceratium и Agastomyrma . 22– Pachycondyla oligocenica sp. n. , голотип PIN 3429/1112, самец; 23– Pachycondyla aberrans sp. n. , голотип PIN 3429/104, самец или самка; 24–25– Proceratium petrosum sp.n. : 24–голотип PIN 3429/103, самец, 25– переднее крыло восстановлено по прямому и обратному отпечаткам;26– Agastomyrma laticeps sp. n. , голотип PIN 3429/1178, PIN 3429/1173 (обратный отпечаток того же экземпляра), самка, реконструкция по обоим отпечаткам. Measurements of holotype, mm: AL 2.5; PtL 0.6; F3L 1.4; FWL~5.7. Comparison. Loss of cell rm rarely occurs in Ponerinae. Yet this character is known in Pachycondyla and in the extant Buniapone amblyops Emery, 1887. Etymology. Aberrans is the Latin for deviate, aberrant.
