DISCUSSION OF SPECIES 



Group ASOPUS 



The females of this group have the mandibles tridentate; the 

 thorax longer than broad, subhexagonal, and without a scutellar 

 scale; and the pygidium rugose. The second abdominal sternite of 

 the males has a median, longitudinal row of short, erect hairs on the 

 apical half, simulating a carina.
