This high-elevation species is restricted to mountain-tops above 1000m in a small area within Queensland’s wet tropics where it occurs in rainforests.
Shattuck (2009) - Majority of carinae on pronotum and mesonotum gently curved across width of mesosoma; sides of head behind compound eyes with 2–3 longitudinal carinae running the length of the head. The combination of arched mesonotal sculpturing and elongate carinae on the sides of the head behind the eyes will separate this species from all others in Australia. This species is sympatric with Myrmecina alpina, another high-elevation species, and these are the only Australian species with carinae on the sides of the head behind the eyes.
