Holotype: BRAZIL. Amazonas , 26km NE Manaus, Reserva Ducke, 22.xii.1988, J.A. Rafael, Arm. suspensa 1.5m (1 , INPA).
Comments
Heteromeringia mediana differs from other New World Heteromeringia in having a median brown stripe on the scutellum and a very large M 1+2 ratio. Its genitalia are similar to those of H. quadriseta , but the epandrium is shallower, the surstylus is slightly angulate, the hypandrium is more elongate and the phallapodeme is curved.
