Known distribution



Host plants




Two males from Cerro Zunil in the BMNH represent Jacoby's variety of D. selecta. After study of genitalia in one of these males we found that internal sac armament is quite different from D. selecta. Therefore, we treat it as a separate, not yet named species, D. s2n.


Potential problems with identification

D. selecta is very similar to D. s2n and D. sexmaculata. D. selecta is more slender than two other species and it differs in the shape and positions of the spots on the elytra. The head in D. selecta is orange or rufous, but green in D. sexmaculata.
