Additional specimens.

Brazil • 1 ♂; Amazonas, Reserva Ducke, 26 km N of Manaus; 31 Aug. 1982; J.A. Rafael leg.; INPA.

Diagnosis.

Body length: male: 8 mm (female unknown). A sturdy, entirely black species without pale wing markings, without golden pile on thorax or abdomen, with a produced vertex. Male genitalia as in Fig. 265 .

Notes.

In the specimen from Brazil the vertex is slightly less produced than in the type material, the median bulge on the face is somewhat less prominent, and the scutellar calcars are more or less straight (as opposed to curved and converging in the type specimens). The taxonomic value of these characters can only be assessed when further specimens become available.

Distribution.

Known from the Brazilian state Amazonas, French Guiana, and Suriname.
