In Proagoderus, the prothorax is produced in the middle of the 

 base in a strongly pronounced, often laminate angle ; the clypeus is 

 never bi-dentate, the elytra never testaceous, and the basal joint 

 of the labial palps is not dilated; this last character differentiates 

 Proagoderus from Diastellopalpus.
