Holcoponera ilimani

Identification
This species is nearest to Gnamptogenys strigata and Gnamptogenys pittieri but they are separable on several on several accounts: the posterior petiolar node face is not sharply set off and has raised costulae; in dorsal view their node is anteriorly convex, not straight; standing hairs on the body and especially the scapes are abundant, scape pilosity is longer. In G. pittieri the anterior transverse costulae of the pronotum curve around gently at the sides. (Lattke 1995)

Coarsely costulate strigata group species. With head in frontal view vertexal margin convex; anterior pronotal face with 3-4 costulae that sharply bend back laterally to become longitudinal; declivitous propodeal face with longitudinal costulae; node anteroposteriorly compressed, its posterior face sharply marginate laterally with a flat to slightly concave surface and effaced sculpture; anterior postpetiolar face with 2-3 transverse costulae, rest longitudinal; postpetiolar sternum with longitudinal costulae; lateral mesocoxal face with oblique, rough costulae and that of metacoxae with rough rugulae; metacoxal tooth low and triangular. Body black with yellow-brown legs and scapes; abundant appressed pilosity on legs and scapes, but no standing hairs.
