Holotype male, Nova Teiitonia, Santa Catariiia, Brazil, Apr. 27, 

 1950 (F. Plaumann), on indefinite loan to U.S. National Museum 

 from North Carolina State University. Three male paratypes at 

 North Carolina State University. This species was described from 

 seven male and seven female specimens, all from Brazil (March, 

 April, and July). 



B. ohunca, new species, appears to be related to B. abdominalis 

 (Van Duzee) but can be distinguished by the shape of the aedeagus 

 and the deeply incised ventral margin of the pygofer (see key).
