This species has the body robust, strongly convex, densely pubescent, the head with a strongly procurved “U” shaped raised carina distinctly tuberculate at both ends. Overall color orange with localized dark patterns on pronotum and elytra. The underside and legs are pale yellow; the antennae orange-yellow except the club, dark-brown. The stridulatory peg is present.

). Clypeus trapezoidal in outline, strongly obliquely sloping forward, the anterior margin finely denticulate, the interval between these small denticles with a small yellow-orange bristle directed forward. Posterior declivity of clypeus relatively abrupt behind the carina, flanked on both sides by the clypeofrontal suture, slightly impressed and extending laterally up to the level of the anteromedial angle of the eye. Head surface shiny, covered with tight but not contiguous medium setiferous granules; a median longitudinal area, smooth, from the base to the middle of the head in front. Labrum transverse, dorsally convex, hyaline, long pubescent, strongly emarginate in the middle front, with a distinct raised transverse ridge in the middle. Eyes moderate in size, globose, strongly produced laterad with spaced long setae along their inner edge. Mandibles subequal, falciform, slightly concave dorsally, the surface matt, distinctly wrinkled on a microreticulate background. Mentum oblong, subquadrangular, weakly depressed in front. Antenna 10-segmented, the scape and funicle yellow-orange, pubescent, the club shiny, dark-brown except for narrow whitish apical part.
Transverse, strongly convex, entirely margined, distinctly emarginate behind the head with a thin hyaline membrane in front, the lateral edges and base fringed with setae. Front angles prominent, projecting forward, the posterior ones obtusely rounded. Pronotal surface with a very dense punctation, consisting of small, tightly packed, medium-sized setiferous rounded granules with yellow-orange setae erect upwards. The setae located laterally at the front angles distinctly longer, black, curved upwards. A short median longitudinal furrow at basal third, extending forward to the anterior margin as a thin, darkened line. Pronotum uniformly orange with two black paramedian spots along the front margin, two other spots more broadly spaced along the base, and a distinct darkened fovea in the middle of each side.
Transverse, dull, densely pubescent, their color coarsely similar to that of the pronotum. Striae well-marked, relatively shallow, consisting of aligned sunken medium points separated by about 1–1.5× their diameter. Intervals almost flat, punctation strong and tight consisting of small setose granules on a microreticulate background, the minute setae erected, distinctly darkened. Humeral callus well developed. Elytral color patterns as follow: a thin transverse dark band on the fourth interstria along the front margin, a round black spot located on the humeral callus and a transverse median dark band interrupted in the middle, merging laterally with the next band located in the apical third of the elytra. Scutellum elongate, triangular in outline, the lateral edges darkened, the disc slightly depressed longitudinally in the middle.
Strongly convex with six visible ventrites (III–VIII). Surface smooth, shiny, microreticulate; ventrites with minute setigerous tubercles along their front margin, the disc with medium setae roughly aligned. Tergite VIII (pygidium) brownish-black, pubescent, the punctation consisting of small close setose granules embedded on a microreticulate background; a lightened transverse band along the upper edge. Tergite VII (propygidium), entirely orange with trapezoidal interlocking mechanism. Stridulatory apparatus (sternite VI) present.
Protibia quadridentate externally, the median tooth (third) barely visible, the basal tooth very reduced, spinose, pointed; inner apical angle of protibia with a short, acute pollex directed anteriorly (
