The male holotype from Tucaman, Lules, Argentina, Nov. 13, 1953 

 (Wygodzinsky) , is in the collection of R. Linnavuori and has been 

 examined. An additional specimen from Curitiba, Parana, Brazil, 

 July 1961 (N. L. H. Krauss), in the U.S. National Museum has been 

 examined. 



B. a. fuscipennis Linnavuori is closely related to the nominate sub- 

 species but can be distinguished by the pair of lateral triangular 

 processes on the aedeagus. This subspecies is also distinctly larger 

 in size.
