DIPTERA — STONE 



Wing hyaline except for dark stigmal spot on anterior inner basal 

 portion of coxa and tarsus; midleg yellow except for dark coxa, apical 

 two- thirds of femur, and tarsus; hindleg yellow except for dark coxa, 

 apical two-thirds of femur, and tarsus. Abdomen with three dark 

 spots on tergum I, usually clearly separated; terga II-V black on 

 basal half, yellow on apical half; terga VI and VII dark except very 

 narrow basally ; venter yellow ^dth sterna III-V more or less darkened

Male: Coloration as in female except abdomen beyond tergum I 

 with Mdder black areas. Terminalia indistinguishable from those of 

 the type of 0. antillarum. Lane and Andretta (1958, p. 517, fig. 19) 

 figured those for antillarum.

This species would run in the key of Lane and Andretta (1958) 

 to 0. similans Lane and Andretta, but similans has all coxae entirely 

 dark (not implied in key), the base of tergum I broadly dark, the 

 meson otum and pleura mostly dark, and the stigma not crossing 

 vein Ri. From antillarum Lane and Andretta, danista differs in 

 having the knob of the halter dark, the sternopleuron entirely yellow, 

 and terga IV and V mth broad apical yellow bands rather than with 

 only lateral spots. 



The name of this species (from the Greek word "danista," meaning 

 "money-lender") was suggested by the three dark spots on the fkst 

 tergum reminiscent of a pawnbroker's sign.
