Fronto-orbital and parafacial plates black with dense, light golden-yellow pollinosity ( Fig. 1 C–E); postocular strip black with silvery pollinosity; parafacial setae in one row, weak; fronto-orbital plate with rows of fine setae. Frontal vitta black, about 3 times as broad as fronto-orbital plate at the narrowest point; frons at vertex 0.2 times head width; frontal setae 13–15; outer vertical seta differentiated from postocular setae; one reclinate orbital seta. One pair of strong ocellar setae, directed antero-laterally. Gena ground color black, with black setae, height approximately 0.2 times eye height in lateral view; postgena with black setae. Antenna with first flagellomere brown, not reaching level of vibrissal insertion, 3 times as long as pedicel; pedicel brown; arista long plumose in basal 4/7. Palpus black, not expanded in distal part.
