NEOTROPICAL REGION. 
There are two endemic Neotropical genera—Blesochetophora and 
Cladocheta. 
The region is also characterized by the large number of 
species of the genus Curtonotum, which is apparently rare in all other 
parts of the world. The 5 cosmopolitan species of Drosophila and the 
6 species previously mentioned as occurring also in the Nearctic 
(Chymomyza procnemis, Drosophila hydei, D. mulleri, D. simulans, 
Leucophenga maculosa, and Pseudiastata nebulosa) are the only Neo- 
tropical species also known to occur elsewhere. 
Adams has recorded 
Drosophila willistoni (as D. pallida Williston) from Rhodesia; but in 
view of the large number of closely similar species in this group, this 
identification can not be accepted as final. 
recognized species as endemic.
