: 261), there is very little dimorphism observed between males and females of the syntype series beyond characters of the tarsi. The punctation and sculpture are very weakly dimorphic, both sexes being almost entirely impunctate, except for the weak discal rows and a few scattered punctures near the elytral apex. The punctation is slightly less impressed in females, with discal rows slightly less prominent. The relative difference of punctation between the male and female syntypes of this species is so slight that splitting them up in the key as did
