Pronotum 1.6 times wider at base than long at midline ( Fig. 17 ). Frontal margin only slightly projected forwards, anterior angles apparent, posterior angles acutely projected, slender. Disc rugose, with long light pubescence. Elytra parallel­sided, 3.7 times longer than width at humeri. Costae inconspicuous, covered with dense light pubescence. Phallus very slender, curved in middle part ( Figs 7, 8 ).
