Hosts. Reared from several types of leaf galls induced by Cecidomyiidae on Inga vera ( Fabaceae ). These are small (1–3 mm) galls found on the underside of the leaf: “bullet gall” (capsule-shaped) ( Fig. 7 ), “modified bullet gall” (irregular-shaped, probably modified by a Tanaostigmatidae inquiline), blister-like gall, and a fuzzy spherical gall ( Fig. 6 ) (P. Hanson, unpublished).

Distribution. Belize, Costa Rica.
