specimen at hand I cannot determine the sex without dissection. From 

 the geuitalia of the dried specimen it does not seem to be a male, but

 Styringomyia, some Tipula, etc. With this statement I have discussed 

 the specimen above as being a female. 



Habitat. South Africa. 



Holotype, ? ?, Ceres Division, Matroosberg, altitude 3500 ft.,
