Hab. Cameroun. 



Holotype, c% Douala, 1921 (Sergt. Barthélémy). 



Type in the collection of the Paris Muséum. 



Dicranomyia barthélémyi is most closely allied to D. mendica Ale- 

 xander (Cameroun) but is readily distinguished by the détails of 

 venation and the structure of the maie hypopygium. This interesting 

 crane-fly is named in honor of the collector. 



Genus DICRANOPTYCHA Osten Sacken. 



The genus Dicranoptycha now includes fifteen species, occurring 

 in the Holarctic Région [North America (6); Europe (2); Japan (2)]
