Pronotum elongate, it surface presenting very small tubercles giving a silky aspect; anterior margin straight, posterior margin slightly sinuated; disk raised in the middle, presenting on each side a curved impression; there is a line of deep points near the posterior margin; coloration yellowish-brown with four small brown lines near the anterior margin and another one near each anterior margin and another one near each anterior angle; lateral lobes with inferior margin very strongly sinuated, finely denticulated in the anterior half, with posterior angle presenting a few deep points. Abdomen yellowish-brown; 10th tergite with median part a little lifted, limited by two small oblique ridges; epiproct small, triangular with rounded top.

Anterior tibiae rather strongly dilated, perforated with two large, oval tympana. Posterior tibiae without spines. Elytra long and narrow; their surface presenting a silky appearance due to the presence of very small tubercles covering the surface of the areolae between the veins; dorsal field yellowish with 7 very regular, oblique, brown lines along the principal veins which are partly confounded in the reticulation; this is rather wide in the superior part, very close towards the inferior margin. Wings longer than the elytra, darkened towards the anterior margin and at apex, presenting yellow, thickened veinlets.

This species is remarkable for itcolouration and the elytra venation; it further presents a very special aspect owing to the presence of numerous small tubercles.
