Ibitya communis (Risbec) comb. n. Fig. 37

Orasema communis Risbec, 1952: 412-414. Type data: Madagascar: Bekily. Lectotype male (examined), by subsequent designation Heraty, 1994: 59. Type depository: MNHP. Citations: Heraty, 1994: 59-61 (subsequent description, both sexes, illustrated); Heraty, 2002: 51 (catalog).

Discussion.

A new host record is made for Pheidole veteratrix Forel based on a single collection that included a soldier gripping the wing of an adult I. communis , 5 female and 1 male pupae, and two unparasitized ant larvae. The pupa has the basic features of an Orasema , but with additional pustulate swellings not found in other taxa.

Pupa

(Fig. 37 ). Length 5.1-5.5 mm. Typical morphology for Orasema , including three swollen tubercles over the petiolar region and pronounced linear swellings along the posterior margins of Mt1-5. Additional atypical tubercular swellings occur over each anellus, each side of the occiput, on the dorsal margin of each flagellomere, laterally on the anterior face of the mesoscutal midlobe, axilla, laterally (paired) on the mesoscutellum as well as a single medial posterior tubercle, and with paired lateral swellings associated with the linear swellings on each of Mt1-5.
