Among the four species in this group with individuals exhibiting contrastedly paler elytral margins, this species (Fig. 149A) is diagnosed by the very shallow elytral striae, with only the sutural and 2nd striae impressed on the disc. The pronotal median base is less punctate than in the two bicolored species with punctate striae;
