Both sexes of this species can be distinguished by the following combination: head and mesosoma dull to granular; clypeus uniformly punctate. The female could be diagnosed by the shiny and nearly impunctate lower paraocular area. The male is unique from all other species in the genus by the following: head wide with clypeus very short, gena much widened in lateral view, and mandible extremely elongate and slender without a subapical tooth. The female of this species is most similar to

slightly wider than long, L:W = 0.96:1. (1) Labrum and mandible: dark brown, with subrectangular basal area, medial length equal to half of width, flattened basal elevation, raised apical process, narrow triangular distal process; basal area of mandible dark brown, mandible red apically. (2) Clypeus: shiny, nearly half apical surface dark purple-brown; slightly shorter than supraclypeal area, extending about 0.95X length below lower eye margin, weakly convex in lateral view, protuberance about equal to supraclypeal area; punctures separated by 1–2pd, fine basally becoming coarser apically. (3) Supraclypeal area: as wide as to slightly wider than long, largest width subequal to length from upper clypeal margin to lower margin of antennal sockets; entirely granular, convex, protuberance greater than clypeus; punctation even basally and laterally, separated by 1–2pd, becoming sparse medially. (4) Lower paraocular area: dull above and towards supraclypeal area, shiny apically and laterally along inner margin of compound eye; punctures separated by 1–3pd except most of lower paraocular area where surface is shiny and impunctate along inner margin of compound eye below level of antennal sockets and below upper clypeal margin towards paraocular lobe.
