Eyes small, hemispherically prominent, their interocular distance 1.58 times maximum eye diameter. Antennae shortly flabellate, black, 11-segmented, densely pubescent. Maxillary palpi slender, apical palpomere pointed; labial palpi similar in shape. Pronotum and elytra yellowish brown to orange, densely covered with red setae. Pronotum 1.16 times wider at base than length at midline, concave frontally, widest basally; posterior and lateral margins elevated, posterior angles considerably projected, sharp; disc of pronotum with longitudinal carina anteriorly, with slender areola posteriorly; vestiges of carinae in frontal part of pronotum and at lateral margins ( Fig. 22 ). Elytra parallelsided, flat, 3.60 times longer than their width at humeri, with four primary longitudinal costae and five weaker secondary costae. Legs slender, flattened, dark brown to black, with light pubescence. Male genitalia slender, phallus parallel-sided in apical part ( Fig. 28 ). Female unknown.
