This is one of the rarest species of Australian Aenictus, being known from only two collections on northern Cape York Peninsula. Its closest relatives, species formerly placed in the subgenus Typhlatta, are found from India east to the Philippines and south to Papua New Guinea. This species is similar to the PNG species A. huonicus but differs in having more extensive sculpturing on the mesosoma and petiole.

Identification

A member of the currax group. "Eye spots" present on posterolateral corners of head; subpetiolar process generally absent but sometimes present as a slight carina. This is the only known Australian species of the genus with "eye spots" (pale pigmentation on the dorsolateral region of the head capsule).
