 females have a low, cone-like clypeal elevation, which may be reduced 

 to little more than a pronounced convex surface. (2) The hair lobes 

 of the male are very broad, almost meeting medially. (3) The male 

 pygidium is much longer than broad. (4) There are no known prey 

 records for this group.
