Remarks

Jacoby's (1887) description of D. rufomaculata is based on a unique specimen. Smith and Lawrence (1967) mentioned that the holotype is a female. We studied the holotype and found that it is a male. Two additional specimens in the Jacoby's collection in BMNH are females.

 

Potential problems with identification

Internal sac in D. rufomaculata is the same as in D. selecta Jacoby. The color and arrangement of the maculae on elytron allow distinguishing two species clearly.
