Anochetus rufolatus

This rare species is known from a single locality, Lizard Island, a small island located approximately 30km from the Queensland mainland. Nothing is known of its biology.

Identification
Sculpture on front of head extending only slightly beyond eyes; pronotum smooth dorsally, sculptured 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 rufostenus, differing in having the dorsum of the pronotum smooth rather than sculptured, the head longer (head length > 1.11mm) and the petiolar node wider (maximum width > 0.28mm).
