This is distinguishable in the imago by the always distinct median suture 

 of the postclypeus, in both castes by the differing proportions of the mandibular 

 teeth, and further in the worker by the weakly lobed enteric valve seating. It is 

 not known if the abdomen is dehiscent in the worker of A. empodius.
