Material examined.

Holotype male, 180 m off Barrington Tops Forest Road, Barrington Tops National Park [31°57'S, 151°25'E, New South Wales, AUSTRALIA], 11-21 Jan 2012, J.R. Gollan, M.A. Ashcroft, pitfall trap, edge of upland swamp (AM KS122794).

Other material examined.

Known only from type specimen.

Etymology.

The specific name is an adjective in apposition derived from the type locality, Barrington Tops National Park.

Diagnosis.

The tegular apophysis in males of A. barringtonensis sp. n. is distinct amongst the known species of the genus due to the presence of a row of apical teeth, which are visible in lateral view (Fig. 6D).
