DIPTERA FROM NEPAL 67 



Subgenus SCAPTODROSOPHILA Duda 

 Scaptodrosophila Duda, 1923 : 37. 



Pholadoris Sturtevant, 1942 : 28 [teste Wheeler and Takada, 1964 : 185]. 

 ? Paradrosophila Duda, 1923 : 43. 



Type-species : Scaptodrosophila scaptomyzoidea Duda, 1923 : 37 (New Guinea). 



As pointed out by Wheeler (1957) and Wheeler and Takada (1964), re-examination 

 of Drosophila pictipennis Kert^sz, the type-species of Paradrosophila designated by 

 Sturtevant, 1927, is required in determining relationships between Paradrosophila 

 and Scaptodrosophila. The characteristics of this subgenus are most clearly expressed 

 in male genital organs, and Drosophila brunnea Duda and D. pilicrus Duda are 

 tentatively included in this subgenus as they have been included by Duda in his Para- 

 drosophila, although the females alone have been examined by the present author.
