Review of the genus Ammophilomima (= Lagynogaster) (Diptera: Leptogastridae)

The type of Ammophilomima imitatrix Enderlein has on the posterior side of the hind femora a hair flocke not described by Enderlein. The type of Lagynogaster fuliginosa Hermann, a synonym of Ammophilomima, has a similar hair flocke. Both taxa have a petiolate anal cell, bifid epandria, and has processes at the base of the dististyli. The notched free hypandrial apex, rather than the dististyli, serves as a guide for the aedeagal sheath. The dorsal bristles of the hind tibia, mystax bristles, and other characters divide Ammophilomima into several distinct, but informal groups. Separate keys are given for Ethiopian and for Oriental Ammophilomima. Seven new species are described; 27 species are redescribed or translations of the original descriptions given.
