Wings well haired only on distal half; anterior wing veins including 

 m-cu cross vein brown; posterior veins pale; membrane not darkened. 

 Wing length 3.37 mm.; venarum ratio 0.88. 



The rather short, straight, parallel-sided dististyle of the genitalia 

 is distinctive, separating this species from A. marginella (Malloch), in 

 which the dististyle is longer and evenly tapered to the tip (Malloch, 

 1915, pi. 27, fig. 10). 



Allotype: In USNM: Alturas, Modoc Co., July 14, 1948, W.

 anterolateral bristles about 30; dorsolateral bristles multiserial; dorso- 

 medial bristles in two rows, dividing anterior to prescutellar area, 

 extending laterally to join dorsolateral bristles. 



Anterior wing veins dark brown; posterior paler; heavy hairs over 

 entire wing; with oblique lighting macro trichia produces h-regular dark
