This species is distinguished from Leptogaster bancrufti 

 by its larger size, the yellow base of aI)domen, the ycUcv 

 tomentum on sides of thorax, the posterior tibiae less widely 

 black, and by the situation of the cross- vein closing second 

 basal cell.

All the "Walker types have the fourth posterior cell pedunculated. 

 From a cursory examination of the descriptions of species of the other 

 authors these types do not appear to be identical with any.
