 almost or quite impunctate; submetapleural carina complete; pro- 

 podeum moderately short, convex but somewhat flattened apically, 

 subpolished with its apical declivity mat (especially near midlength 

 of propodeum), with rather coarse punctures except on its apical 

 declivity; median longitudinal carinae of propodeum weak, discernible 

 on about its basal 0.4; nervellus broken near its lower 0.3, the dis- 

 coidella rather weak; hind tibia of female about 1.05 as long as hind 

 femur; first tergite about 1.1 as long as wide in male, about 1.0 as 

 long as wide in female, its median longitudinal carinae sharp on 

 about its basal 0.85 in male, on about its basal 0.7 in female; second 

 tergite polished, with rather coarse punctures that are separated by 

 about 0.5 their diameter; ovipositor rather stout, its basal 0.6 straight, 

 its apical 0.4 upcurved (fig. 332, a).
