Body elongate, elytra somewhat ovate and considerably tapered posteriorly, about two times longer than wide. Integumental color as in generic description; lower frons castaneous, upper frons and epicranium piceous; elytron light castaneous at humerus. Head with frons distinctly concave. Eyes with incision half width of eye when viewed from front. Antennae inserted at lower angle of eye incision, comprised of 10 antennomeres, loosely clubbed; scape as long as combined length of funicular antennomeres, pedicel particularly large, subglobose; antennomeres four and six slightly expanded, five and seven cylindric; club antennomeres eight and nine subtrigonal, equal in length, tenth ovoid, slightly longer than eight and nine; filamentous sensilla trichodea on antenna considerably shorter than in sister genus Plocamocera. Mandible not falciform, dentes poorly developed, anterior dens broadly accuminate. Pronotum moderately transverse, anterior margin sinuous, prominently projecting medially, posterior margin broadly sinuous, subapical depression not very prominent, pronotal disc slightly depressed at sides where discal and paralateral trichobothria prominent; pronotum narrowly castaneous along anterior and lower lateral margins. Elytral disc depressed behind humerus, elytral punctations prominent throughout disc and not arranged in longitudinal rows. Vestiture: profuse distribution of bristlelike setae (chaetosomes) on head, pronotum, and elytra; elytron sporadically vested with short silvery decumbent setae that are most prominent as three feebly formed setal pencils at elytral basal third, silvery setae also form oblique broad line at elytral apical half; venter and legs copiously vested with setae that are short and decumbent or long and suberect. Fifth abdominal sternum narrowed distally in females, evenly arcuate in males.
