Aphaenogaster barbigula Wheeler, W.M., 1916 |
This species occurs in semi-arid areas of eastern South Australia, south-central Queensland, western New South Wales and north-western Victoria. It is generally found in forested habitats including Callitris and mulga (Acacia sp.) woodlands (including on red soils), mallee (with and without spinifex grass (Triodia)) and in savannah woodlands, but is occasionally found in grasslands, especially with scattered trees. It is most often found on sandy soils. Nests are always in soil and almost always have large, deep craters around the entrance (Shattuck, 2008). The biology of this species was discussed by Crawley (1922:122).
Identification
Majority of hairs on underside of head located laterally and forming a distinct psammophore; eye relatively small (EI less than 21); scape relatively short (SI less than 106); mandibular sculpture composed of regularly sized striations; petiolar node (in dorsal view) approximately square. The presence of a psammophore will separate this species from all others except A. mediterrae and A. poultoni. It can be separated from these species as outlined in the key to Australian species.

Description
Posterior margin of head nearly flat in full face view, extending laterally of the occipital collar before passing through a distinct posterolateral corner into the lateral margin of the head.

Erect hairs on mesosomal dorsum tapering to sharp points. Propodeal spines reduced to small denticles, or sometimes essentially absent. Petiolar node (in dorsal view) approximately square.
