Extract

The genus Megagrapha Melander is characterized by small size, pubescent eyes, broad thorax, large flattened scutellum, and broad wings. The wing venation is most distinctive, the basal cells being large and subequal, the crossveins confluent, the anal crossvein absent, and the anal vein curving along the caudal margin of the wing. The only other genus with these characteristics is the South American genus Austrodromia Collin, but in that genus the crossveins are distinctly basad of the apex of the subcostal vein, whereas in Megagrapha they are approximately opposite the apex.
