THE TABANIM; OF COLOMBIA (DIPTERA) 1

The tabanid fauna of Colombia is rich and extremely varied. 
In the northwestern part it resembles that of the Republic of 
Panama, which is now well known through G. B. Fairchild’s 
prolonged investigations. In the northeastern areas it is similar 
to that of the adjoining districts of Venezuela, a fauna which 
has recently been listed by A. Stone (1945). The fauna of the 
southwestern highlands has affinities with that of Ecuador. 
Finally many of the species of the great Amazonian rain forest 
extend into the southeastern territories. 
At present, however, this vast country has been little investi- 
gated entomologically. Our preliminary list of definitely re- 
corded species will probably be more than doubled by future 
discoveries. Indeed, our only purpose in publishing it is to incite 
to further collecting. The earliest records of Colombian tabanids 
by Macquart (1846 to 1855) were indefinite as to locality and 
some of his species are at present unrecognized. Schiner (1868 ) , 
v. Roder (1886), and Ricardo (1902) added a few species. In 
recent years, Enderlein (1925), Szilady (1926), Dunn (1929), 
Krober (1925 to 1940), and Antunes (1937) made more impor- 
tant additions. 
The present enumeration includes all species recorded thus 
far from Colombia; but we have clearly indicated which of these 
we have not seen. 2 The asterisk, on the other hand, indicates 
the species of which we have studied specimens taken in Co- 
lombia. Material was seen from the Museum of Comparative 
1 Published with a grant from the Museum of Comparative Zoology at Har- 
vard College. 
2 Entomologists should be warned not to trust always the locality record 
“Bogota” so common in the literature. Often it means merely that the specimens 
were shipped from Bogota to Europe, although they may have been collected in 
some other section of Colombia.
