Description: body: elongate-oblong, moderately robust. Head, pronotum, elytra, legs, and ventral faces uniformly glossy or semi-glossy black. Head quite large, triangular; surface weakly wrinkled, face short; mandibles not excessively long, but rather broad-black in colour. Palpi dark brown or black with pale tips. Eyes heavily reduced in size, weakly bulging at a sort of forward angle; a ridge should begin just above the back of the eye, then travels over the eye, ending at the base of the scapus. Antennae somewhat clavate, short; antennal pubescence begins on the second antennomere following the pedicel. Pronotum weakly cordate, basal margin weakly truncate; basal margin sinuous, hind angles squared, lateral bead should have several minute notches near the hind angles, lateral margins curve up from the hind angles, outwards, then back in towards the head at the front angles, at which point they curve back inward and meet, creating the front margin. Median line deep, broad. The dorsal hind angles each have two narrow, sinuous depressions; one small, which is just inside of the crook of the hind angle, the other appears almost the same shape, but about twice the length of the first, and is found between the smaller depression and the median line. Basal margin covered in shallow wrinkles; rest of disk covered in similarly shallow wrinkles. 7 shallow, pitted striae per elytron, intervals flat; two parascutellar pores, one on each elytron. Laterobasal ridges entire, lateral margins rounded somewhat, apices weakly sinuous, nearly squared.
