BREDIN-ARCHBGLD-SMITHSONIAN 

 BIOLOGICAL SURVEY OF DOMINICA 



2. New Species of Diptera from Dominica 

 (Anisopodidae and Bibionidae)^ 



By Alan Stone ^ 



Family Anisopodidae 



Recent collecting by J. F. G. Clarke, H. E. Evans, O. S. Flint, Jr., 

 R. J. Gagne, and W. W. Wirth for the Bredin-Archbold-Smithsonian 

 Survey of Dominica resulted in 34 specimens of two apparently 

 undescribed species in two genera of the family Anisopodidae. The 

 Mycetobia species is the third one described from the New World and 

 the second from the Neotropical Region. The abundant Olbiogaster 

 species has male terminalia apparently identical with those of 0. 

 antillarum Lane and Andretta from St. Croix, but the color differences 

 are too great to permit determination as that species. A second 

 Olbiogaster is represented by a single male with very distinctive 

 terminalia. 



Mycetobia litnanda, new species 



Female: Vertex black, the ocelli yellow; eyes separated by slightly 

 less than width of anterior ocellus; occiput laterally yellow; antenna 

 black, the scape and pedical slightly brownish; face yellow; palpi and
