Eyes small, hemispherically prominent, their frontal distance 1.29 times eye diameter. Antennae shortly flabellate, black, 11-segmented, strongly covered with short, light pubescence. Maxillary palpi slender, apical palpomere pointed. Labial palpi similar in shape. Pronotum and elytra from yellowish brown to red, covered by red setae. Pronotum 1.52 longer than width at base, frontal part strongly projected, basal and apical margins elevated; posterior angles sharply projected, sharp; pronotal disc with longitudinal ridge and slender areola in posterior part. Elytra convex, with four primary costae, secondary costae form square to rectangular areoles. Legs long, slender, strongly flattened, dark brown to black, densely covered with light setae, two terminal tarsomeres lighter, with yellow setae. Male genitalia moderately robust, widest in apical third ( Fig. 24 ). Female unknown.
