 tum smooth and polished; notaulices fine, not foveolate; mesosulcus 

 weak, not foveolate; mesopleuron smooth, polished, its upper and

 metapleuron smooth and shining; propodeum mostly smooth except 

 for carinae defining the areas, spiracle short ovate. First abscissae of 

 radius and basal vein long and about equal ; fourth abscissa of cubitus 

 about twice as long as third ; second abscissa of cubitus slightly longer
