The well-developed anterior fronto-orbital bristle, the presence of 
two sternopleural bristles, and the structure of the male terminalia 
will aid in distinguishing this species.

ment dark brown to black, arista black and minutely pubescent; 
anterior fronto-orbital bristle about one-half the height of the posterior 
bristle; cheek-eye ratio from 0.58 to 0.69. 
Mesonotum brownish with grayish pollinosity; about 7 rows of 
setae between the dorsocentrals; scutellum without setae; pleura 
orangish brown; propleural bristle strong, several setae at its base; 
mesopleuron with several setae in anterior corner; 2 sternopleural 
bristles (the anterior one weaker) and 2 or 3 setae or hairs anterior 
to the bristles. 
Legs yellowish brown; 1 strong dorsal preapical bristle on middle 
tibia, with another weaker bristle located distally below and behind 
the preapical bristle; middle tibia with several ventral apical bristles; 
middle femur with rows of bristles anteriorly.

LrenetH.—5.0—-5.6 mm.

Remsrks.—The type is in the collection of the Academy of Natural

were reported to be the same. The cheek-eye ratio of the type was
