Identification

Sympistis arizonensis can be distinguished from related Sympistis by genitalia and geographic distribution. The species was historically confused with Oncocnemis species before the 2008 generic revision. Precise identification requires examination of genitalia structures. It may be distinguished from the superficially similar Polistes arizonensis (a paper wasp) and Phidippus arizonensis (a jumping spider) by fundamental differences in body plan: Sympistis arizonensis possesses scaled wings and a coiled characteristic of Lepidoptera.
