Species Notes: Mitchell (1960: 229, and subsequently Hurd 1979: 1787) included A. media Viereck as a synonym under A. durangoensis Viereck and Cockerell, 1914). As LaBerge (1980: 464) was not able to locate the type material, it is not known what his placing this species into synonymy under A. rufosignata was based on, though it is included here as it is the most thorough and recent taxonomic treatment of the group.
