Description

Unless otherwise noted the text for the remainder of this section is reported from Bingham 1903.

Worker

Fuscous brown, the antennae, thorax beneath and legs slightly paler, the whole head, thorax and abdomen pilose and pubescent, especially the abdomen. Head sub-cordate, the occiput widely emarginate, the posterior lateral angles prominent but rounded; mandibles triangular, punctured and pubr^scent, armed along the masticatory margin with 9-10 small black teeth: clypeus broadly triangular, slightly convex, its middle portion anteriorly bent down and flat, the margin entire. Thorax with the pro-meso- and meso-metanotal sutures very deeply impressed, the pro- and mesonotum, slightly convex, level; the metanotum moderately gibbous, posteriorly obliquely truncate; legs moderately long and stout, with short, somewhat abundant pale pilosity. Node of the pedicel somewhat thick, its height and thickness subequal; abdomen oval, proportionately longer than in I. anceps.

Length: 3 - 3.5 mm
