Basal area of second tergite 0.2–0.4 times as long as remaining part of tergite; apical area short, 0.3–0.5 times as long as remaining part of tergite; areas sometimes indistinctly delineated. Median length of second tergite (with areas) 1.0–1.1 times its basal width, 1.5–1.8 times median length of third tergite. Third–fifth tergites rugose-striate in basal 0.5–0.3.

COLOUR. Rarely body paler. Pterostigma sometimes mostly brown, pale basally and apically. Metasoma sometimes light brown or light reddish brown. Otherwise similar to female.

Diagnosis

This new species distinctly differs from the remaining two described species of the subgenus Afroipodoryctes [I. (A.) insignis Granger and I. (A.) reunionus sp. nov.] by having the mesoscutum entirely densely and distinctly granulate and almost entirely covered by short pale setae (vs smooth and mainly glabrous).

Distribution

Réunion.
