Taxonomic notes: Cockerell (1918) indicated that his A. politissima Cockerell, 1931 was close to A. trachandrenoides Viereck, 1904, the latter of which he indicated was never fully described.

LaBerge (1973: 306) incorrectly recorded the date for A. dolichotricha Cockerell, 1924 as 1904; as Cockerell (1924: 349) indicated two syntype males (collected by W.P. Cockerell and C.L. Corkins), the mention of a particular specimen collected by W.P. Cockerell is considered a lectotype designation.
