Scenopinus inquilinus S6guy, 1931, p. 113. 



This medium sized fly is easily distinguished in the male by the 

 single white band on the abdomen, the antlerlike shape of the male 

 aedeagal parameres, and shape of the ninth tergum. The female can 

 probably be positively identified only by the bursal cavity. Their 

 larvae have been found in Polyporus, in June and July, with adults in 

 July.
