Description: body: elongate-oblong, moderately robust.  Dorsal and ventral colouration should be fully glossy or semi-glossy black, excluding the outer mandibular margins and the lower mouth parts, which are dark, opaque red. Head triangular, face long; head riddled with shallow, mostly horizontal wrinkles. Mandibles somewhat broad, curved at apices. Eyes not reduced, should be semi-spherical, bulging laterally. Antennae fully black, antennal pubescence begins on the second antennomere following the pedicel. Pronotum transversely semi-ovate; lateral margins rounded, pronota widest near the head; lateral bead begins at the acute front angles, travelling along the lateral margins, past the sharply-obtuse hind angles, then abruptly ending at the base of the median bulge. Basal region of the pronotum heavily micropunctate, mostly across the lower median bulge. Triangular indentations should be found on either side of the lower median bulge. Median line shallow, with few weak wrinkles spanning out from it laterally; rest of pronotum relatively smooth. 7-8 well-defined striae per elytron; two fovea should be found on the 2nd stria; two fovea on the 3rd stria, together giving the appearance of a staggered lineup of four somewhat evenly spaced fovea. Intervals weakly elevated. Laterobasal ridge entire, one parascutellar pit per elytron.  Humeral shoulders rounded-obtuse, lateral margins rounded, apices rounded-weakly sinuous.
