Explanation of Names
Rhinophoridae Robineau-Desvoidy 1863
worldwide, ~170 spp. in 26 genera(3); in our area, 2 native spp. (Bezzimyia americana and B. busckii) and 3 spp. introduced from Europe: Melanophora roralis, Phyto discrepans, and Stevenia deceptoria
Rhinophorids have a weakly developed subscutellum, narrow calypters, and a closed r5 cell. Melanophora have dark wings, M meeting R4+5 perpendicularly far from wing margin, Phyto have clear wings, M meeting R4+5 obtusely near wing margin.
