Anochetus alae

This rare species has been collected only a single time, a nest found by Phil Ward under a stone in a gully rainforest.

Identification
Propodeal angles produced as spines; sculpture on front of head extending only slightly beyond eyes; body large (head length > 1.78mm, head width > 1.53mm); scapes relatively long (scape length > 1.60mm); mesonotum with a few transverse, irregular ridges.

This species is larger than the similar Anochetus veronicae, and differs in having well developed sculpturing on the mesosoma, a more convex anterior petiolar node face and more abundant pubescence on the scapes.
