 area of frons rather weakly defined; occipital carina rather narrowly 

 incomplete above; clypeus moderately wide, the median half of its

 evenly from the base to a rather slender apex; frons weakly and evenly 

 convex, a little impressed above each antennal socket and weakly 

 swollen between these impressions; hind ocellus separated from eye 

 by about 0.85 its long diameter; hind margin of mesosternum with 

 an unusually conspicuous median shelf, on each side of which is a 

 blunt small lobe; costula complete and strong; second lateral area of 

 propodeum with about 7 hairs laterally and apicolaterally ; hind 

 femur about 2.25 as long as deep in male, about 2.15 as long as deep in
