Body covered in black and dark gray scales, with longitudinal, black-bordered white stripes across the lateral edges of the pronotum and elytral humeri. Pronotum evenly punctured across dorsal surface, often with a shiny, impunctate longitudinal midline. Rostrum evenly curved, variably longer in females than in males. Abdomen: first and second sternites variably concave medially in males, convex or flat in females. Scale pattern usually cryptically patterned with contrasting brown, black, gray, and dull yellow scales. Sclerolepidia varied: prominent and protruding in some species, forming low, indistinct tubercles in others. Internal sac of aedeagus may be tuberculate (roughened) in anterior half or with a non-hooked protruding structure.
