Body with extremely short sparse erect to decumbent silvery setae.
Head
: In dorsal view, wider than pronotum, narrowed and gently rounded behind eyes, slightly concave in rear; vertex and brow moderately reticulate-punctate; POD 1.36 OOD; mid ocellus not lidded; brow without TFC; face fairly broad, least interocular distance as long as eye height; scapal basin shallowly concave, broadly cross-ridged; subantennal space as wide as MOD; malar space 0.4 MOD long; clypeus bald, polished (impunctate), slightly convex in the disc, with apical margin straight; genae distinctly narrow; genal carina weak, contiguous to outer ocular margin; mandible with a small subapical tooth. F1 2× as long as broad, 1.25× as long as pedicel, 1.6× as long as F2 and F3.

Pronotum gently declivitous in front, with humeral part broadly rounded; mesoscutum with complete notuli divergent in front, with distinct parapsidal lines; tegula ovoid, normal-sized, fairly shallowly punctate; metanotum evenly convex; propodeum vertical (invisible in dorsal view); propodeal lateral angle slender and digitate, pointed to backward, strongly concave posteriorly, adjacent to metanotum; mesopleuron moderately angulate ventrally. Tarsal claws edentate, hind tibiae with dark drop-shaped spot occupying more than apical third of inner surface. Fore wing with three closed cells: costal, radial and cubital cells;
