This is very similar to A. lophyri and may prove to be a subspecies 

 of it. The punctures on the head and body are distinctly finer and 

 denser than in lophyri, punctures on second tergite a little finer 

 and denser, and the ovipositor tip perhaps a little narrower. The 

 punctures on the center of the face are adjacent and crowded.

 infuscate; hind tibia brownish ferruginous, its base a little paler; 

 hind tarsus brown, the apical 0.12 of the first segment, some or all 

 of second segment, all of third and fourth segments, and usually 

 the base of fifth segment, white; abdomen ferruginous, the basal 

 0.7 ± of the fu'st segment more or less infuscate, fifth segment often 

 more or less infuscate, and sixth and seventh segments black, the 

 seventh \vithout a white spot.

 dially; mandible usually with a ferruginous stain; palpi brown;
