Diagnosis.

The only species with faint metallic integument of head and thorax.

Description.

Female holotype: body length: 6 mm; head width: 1.9 mm. Relative head measurements: HW 50, ASD 3.3, AOD 8.4, HL 38, IAD 10.0, LFW 29, OAD 13, OOD 11.3, OW 16, UFW 36, HW/HL 1.3, LFW/UFW 0.8. Relative wing measurements: MSR 1.61, FSR 1.18, SFR 1.00.

Structure: terga anteriorly not depressed; BTP pointy; BTP/tibial length ratio 0.26; inner hind tibial spur ciliate; flagellum short, F1-9 wider than long.

Sculpture: scutum dull, transverse lineo-reticulate and openly punctate, with faint metallic shine; metapostnotum transverse lineo-reticulate to finely irregular roughened; T1 lineo-reticulate, T2-3 transverse lineo-reticulate; clypeus large openly punctate, microsculpture between punctures; supraclypeal area small densely punctate; scape relatively slender about 5 times as long as wide proximally; ocellocular area minutely roughened; frons irregularly pit-reticulate with faint metallic shine.

Coloration: terga anteriorly brown, posterior margins almost not transparent; scopa light brown, lighter ventrally; labrum black; mandibles black with brown tip.

Pubescence: scutum: short, orange-brown, with sparse long hairs; scutellum: short, orange-brown, with sparse long hairs; S5 with dense fringe of white hairs.

Structure: terga anteriorly almost not depressed; BTP short, almost not pointy; flagellum F1 <F2, F1-10 wider than long, F11 longer than wide. S7: dorsal apical lobe absent, ventral apical lobe large, branched setae present on dorsal subcentral apical ridge.

Sculpture: scutum dull, transverse lineo-reticulate and openly punctate, with faint metallic shine; metapostnotum transverse lineo-reticulate to finely irregular roughened; T1-3 lineo-reticulate; clypeus large openly to closely punctate, rough microsculpture between punctures; supraclypeal area small densely punctate; scape almost 4 times longer than wide, roughly sculptured; ocellocular area minutely roughened; frons irregularly pit-reticulate.

Coloration terga anteriorly black, posterior margins almost not transparent, brown; mandibles black with brown tip.
