This rare species is known from a limited number of collections in the Kimberley region of Western Australia, northern Northern Territory and on Cape York Peninsula, Queensland. All specimens were collection from pitfall traps or pan traps.

Identification

A member of the ceylonicus group. Head capsule entirely smooth and essentially uniformly coloured; scape relatively short (scape index < 91); sculpturing on pronotum extending posteriorly onto the main pronotal body; body larger (head width > 0.62mm). This species is morphologically similar to A. turneri but can be separated from it by its larger size and more extensive sculpturing on the pronotum.
