Specimen labels

This rare species has been encountered a limited number of times on Cape York Peninsula, Queensland. Available material is from pitfall traps placed in savannah woodlands.

Identification

Sculpture on front of head extending only slightly beyond eyes; pronotum longitudinally striate both dorsally and laterally; mesonotum smooth and without sculpturing; petiolar node in side view narrowing only slightly dorsally and trapezoid-shaped, with the striations along its entire height; propodeal angle gently rounded. This species is most similar to Anochetus rufolatus but differs in having the dorsum of the pronotum longitudinally striate rather than smooth, the head shorter (head length < 1.04mm) and the petiolar node narrower (maximum width < 0.28mm).
