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.
