Diagnosis

The female has a distinct, mostly oval impression on the front of the clypeus (as in the dregei-group). It is characterized by prolonged paraorbital stripes and strong, dense punctation on the T1. The male is unknown.

Female. TL 5.6–6.6 (5.97) mm, WL 3.7–4.4 (4.10) mm.

Head. Proportions HL:HW 0.93, UFW:LFW 1.58, outline rounded trapezoid. Face with long white stripes at orbits between tentorial pits and foveae; foveae faciales long. Clypeus CL:CW 1.36, with broad impression on front edge, punctation moderate, close. Supraclypeal area comparably flat, above wide, gently connect to frons; frons and vertex with strong, dense to subcontiguous punctation.

Mesosoma. Pilosity sparse, short, white. Tegulae with pale spot. Pronotum black, fairly long angular expanded forward, anterior edge and its dorsolateral angles rounded. Mesonotum, scutellum and mesopleuren matt, punctation moderate and dense. Legs entirely black; wings dimmed, venation dark.
