Ibitya seyrigi Risbec comb. n.

Orasema seyrigi Risbec, 1952: 414-416. Type data: Madagascar: Bekily. Holotype female (examined), by monotypy. Type depository: MNHN. Citations: Heraty 1994: 61-62 (subsequent description of female, illustrated); Heraty 2002: 55 (catalog).

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.
