Mesopleuron and metapleuron densely rugose-punctate; coxal carina present. Scutellum slightly elevated, slightly wider than long, with scattered punctures. Area superomedia slightly trapezoid, widest basally, 1.1x wider than long; costula absent. Area petiolaris without lateral carina. Hind coxa densely punctate and granulate, without scopa.

Rings on flagellomeres 8-13, complete scutellum and narrow stripes on 6 th and 7 th tergites ivory. Mandible except teeth, collare, and hind edge of pronotum and tegula red.

T a x o n o m i c a l r e m a r k This species belongs to the group F of HILPERT (1992) and runs to I. inquinatus WESMAEL in his key. It differs by a higher number of flagellomeres, slenderer 1 st flagellomere and completely red hind tibia and tarsus.
