Front wing 4.9 to 7.5 mm. long; combined face and clypeus about 

 1.02 as high as wide, the face rather strongly convex in a vertical 

 direction, a little less strongly convex horizontally; clypeus of female 

 in profile distinctly flattened, of male weakly bulging; punctures on 

 face and clypeus strong, moderately coarse, on face subadjacent, 

 on clypeus sparse; apical angle of interantennal process about 110°; 

 median swelling of frons moderately strong; hind ocellus separated 

 from eye by about 0.90 its long diameter in male, by about 1.0 its 

 long diameter in female; median half of apical margin of clypeus 

 weakly concave; mandible with sparse, rather coarse punctures, 

 rather broad and its apex unusually broad, its outer face and lower 

 edge more convex than usual, its lower tooth small; costula complete 

 or incomplete; second lateral area of propodeum with hairs all over 

 in many males, but in females and in some males with hairs only 

 basally, laterally, and apicolaterally; areola bounded laterally by 

 strong, low, moderately wide carinae; hind femur about 2.31 as long 

 as deep in male, about 2.12 as long as deep in female; front spur of 

 hind tibia about 3.4 as long as wide in male, about 3.65 as long as 

 wide in female; punctures on second abdominal tergite of moderate 

 size, deep, medially sparse or absent, sublaterally separated by 

 about 1.3 their diameter in male, by about 1.7 their diameter in 

 female; male clasper rather broad, obliquely narrowed from below 

 to a narrowly rounded apex.
