The forehead is flattened, the frontal rostrum rather long, as broad as the first antennal joint, with parallel margins, extended up to a transverse furrow at the base ( Fig. 2C View Fig ). The anterior ocellus is situated at the bottom of a depression nearly at the middle of the rostrum. There is a blackish band behind each eye which continues to the lateral lobes of the pronotum and the lateral field of the elytra. Antennae are very long, annulated with brown and brownish-yellow colour. Eyes are small, globular and projecting laterally. The face is broad and oblique with very short palps. The pronotum is transverse, square, not attenuated in front, with the anterior margin feebly concave and obtusely angular posteriorly.Lateral lobes with rounded corners and inferior margin feebly ascending posteriorly.
