Discussion.

The redescription and illustrations provided by Heraty (2002) are accurate for this species. The holotype was missing the antennae and the labrum was not visible. Based on the new material: antenna with 11 segments, all flagellomeres beyond anellus densely pilose with numerous longitudinal sensilla; flagellum 1.5 × head height; 7 funiculars; F2 1.9 × as long as broad, 1.1 × as long as F3; clava as long as preceding two flagellomeres. Labrum with 9 long digits, each with a long apical seta, digits arranged in clusters of 1-1-3-3-1. Ovipositor as described for O. communis Risbec in Heraty (2002: fig. 82), but distinctly curved cephalad.

A single male of a different species (Reserve Betampona, from sifted litter; CAS, UCRCENT 00417456) also has an antenna with 11 segments and 7 funiculars, a labrum with 7 digits, and a long petiole about as long as the hind femur. The male shares many features with I. seyrigi, and may be the same species, however there are dramatic differences in especially the coarsely rugose scutellar disc.
