Anoplius americanus ambiguus is a of spider wasp in the Pompilidae. As a member of the Anoplius, it belongs to a diverse group of solitary that prey primarily on spiders. The subspecies was described by Dahlbom in 1845. Like other Anoplius , it likely exhibits the characteristic of digging burrows, paralyzing spider prey, and provisioning nests for larval development.
