Distribution

North Brazil.

Remarks

The dissected male specimen has the central elytral spot split into two elongated spots, whereas in the dissected female the spot is undivided (as in the lectotype). It would be important to better compare additional males and females of the species and evaluate whether this is a sexual dimorphism.
