Head about 1.15 times as wide as long, eyes completely atrophied or usually composed from four to five ommatidia located around robust ocular spine; clypeus large, round; frons with large, deep, triangular excavation that is slightly prolonged anteriorly, forming angle at apex; vertex elevated, forming large hump with one well-defined, long medial carina remote from margin of frontal excavation and extending two-thirds of head length; vertexal fove- ae separated, distant from lateral margin of head; surface between carinae almost glabrous; antennae long 1.10–1.15 mm, scape cylindrical, 1.25 times as long as pedicel twice as long as wide, antennomeres III–VII elongate, (III 2.2 times as long as wide, IV twice, V 2.4, VI twice and VII 1.5 times as long as wide), VIII transverse, IX trapezoidal, 1.5 times as long as wide, X trapezoidal, 1.25 times as wide as long, terminal antennomere triangular, about 1.7 times as long as wide. Pronotum slightly, 1.15 times as long as wide and as long as the head, with deep longitudinal excavation in the middle; lateral carinae long and prominent, with large triangular dent in the basal part, median antebasal and lateral foveae well-defined. Elytra simple, wider than long, at sides round, widest in middle.
