2 - Elytra with several separated round whitish spots concentrated on intervals 2–5 and 8–10 (Fig. 4); rostrum about 0.65 times as long as pronotum in male, some up to 0.80 times in female, deeply bisulcate on dorsal surface at basal half, base and apex of more or less equal width; third segment of fore tarsi about 1.10 times, that of hind tarsi 1.05 times as wide as second; aedeagus parallel-sided, very weakly swollen medially, narrowed at apex (Fig. 5).
