Diagnosis.
Differentiated from the other species in the group based on the male cerci that have the ventral branch longer than the dorsal branch and by the male aedeagus that has a thickened sheath, and the valves of that are shorter than the sheath with broadly rounded apices (Figs 4 A, 5 A). Most similar to A. aristus and A. texmex but differs from those by the shape of the male genitalia which in caudal view, has the valves of the aedeagus relatively shorter and broader than in A. aristus (Figs 4 B, 5 B) and by the having valves that that are parallel (Figs 4 A, 5 A) as opposed to diverging apically as in A. texmex. (Figs 4 D, 5 D); in lateral view, the distal edge of the valves is broadly rounded.

Etymology.
The name silverheelsi is a patronym honoring Jay Silverheels. a Native American athlete and actor who most famously portrayed the fictional character Tonto in “ The Lone Ranger ” television series from 1949–1957. Silverheels was one of the first Native American actors to portray a major Indigenous character on a television series. Throughout his career, Silverheels advocated for more inclusion of Indigenous people in media and founded the Indian Actors Workshop in Los Angeles during the 1960 ’ s. This naming honors Silverheels’ cultural impact and the Texas landscapes where the series was set.
Suggested common name.
