Frons extensively silver pruinose, vertex entirely apruinose (including ocellar tubercle). Occiput entirely silver pruinose. Proboscis and palpi dark red-brown, setae white.   
 Thorax: Dark red-brown to black, silver to silver-gold pruinose, white setose.Mesonotum extensively pruinose except for pair of anteromedial stripes and 5 lateral spots (including small parts of postpronotal and postalar lobes). Pleura entirely silver pruinose. Scutellum entirely pruinose, with 2 moderately developed white sctl s accompanied by 3 or 4 smaller setae. Postmetacoxal bridge entirely silver pruinose.

Discal cell with microtrichia in distal part only, costal cell entirely lacking microtrichia.   
 Abdomen: Dark red-brown to black, silver-gold pruinose, white setose. Tergites with narrow apruinose hind margins. Terminalia (Figs 101– 103 paratype): epand in lateral view projecting beyond levels attained by outer lobe of goncx and hypd, tapering to narrowly-rounded tip; in dorsal view lobes broadly fused proximomedially; hypd in lateral view short, curved, with upturned distal end; in ventral view broadly-rounded proximally, tapering to moderately long terminal process with trifurcate apex. In lateral view external lobe of goncx and gonst project well beyond end of external lobes of goncx. Gonst in ventral view fairly straight.
