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.

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.
