Front wing 3.6 to 8.3 mm. long; clypeus elliptic, a little more strongly 

 convex below the middle than above, especially in females, its highest 

 point at about its lower 0.4; temple at midheight of eye approximately 

 flat, about 0.60 as long as eye; sublateral portions of apical carina 

 of propodeum rather strongly sloped, especially in male. Structure 

 otherwise as in /. analis, except that it averages a little more slender.

 is not at all infuscate apically, segment 2 of male hind tarsus is always 

 entirely white, and segment 1 of male hind tarsus has its apical 0.5 to 

 0.7 white. It is even more similar in color to /. analis limata, differing 

 in having a little less white on segment 1 of male hind tarsus.
