Diagnosis: The supraorbital horns of this species are long, projecting perpendicularly to head and bend slightly inwards. The clypeal horn is short, conical and projects forward. The punctures on the pronotum are of two sizes and the coarse punctures are mostly concentrated on the lateral portions of the pronotum. The ventral side of the thorax bears golden setae. The female is similar in most characters, except for the presence of the horns. The mesepisternal punctures often intersect and form a scalloped appearance ( Fig. 13 ).

Redescription: Male. Size: 10—11 mm; 3.5— 4 mm.
