Scenopinus brevicornis Loew, 1873, p. 146. 



This species is known only from the type-locahty in Turkistan. 

 Loew described both sexes; however, I have seen only the type male. 

 Krober (1924) described and illustrated a female which is illustrated 

 here. On the basis of the wing venation, it is doubtful that this specimen 

 is actually the female of S. brevicornis as it does not agree very closely 

 with wings of the type. Two male specimens from the Canary Islands 

 which Frey identified as S. brevicornis are a new species, S. canarius.
