Surstylus small and rounded with long, stout, pointed bristles along distal margin. Internal genitalia as described for H. czernyi , except hypandrium + pregonite without thin median process and minute setulae present distally.

The specific name refers to the median stripe of the scutellum.

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.
