Aphaenogaster mediterrae  HNS  sp. n.

(Figs 11, 12, 19, 20, 28)

Types. Holotype worker, Australia, Western Australia, 21mi. NWbyW Balladonia Motel, 32°12'S 123°19'E, 4 Nov. 1969, Key and Upton ( ANIC) ( ANIC 32-031016); paratypes, 30 workers and one male (same data as holotype) ( ANIC 32-001084) ( ANIC, MCZC, WAMP).

Diagnosis. Majority of hairs on venter of head located laterally and forming a distinct psammophore (Fig. 21); eye relatively large (EI greater than 21, Fig. 19); scape relatively long (SI greater than 106, Fig. 20). This species has a psammophore similar to that found in A. barbigula  HNS  and A. poultoni  HNS  . It can be separated from these species by the presence of a larger eye and longer scape.

Description. Posterior margin of head broadly arched in full face view, the arch beginning at the occipital collar and with at most a weak angle separating the posterior and lateral margins of the head (often posterior and lateral margins forming a continuous surface). Majority of hairs on venter of head located laterally and forming a distinct psammophore, only scattered hairs on central portion. Mandibular sculpture composed of regularly sized striations. Erect hairs on mesosomal dorsum tapering to sharp points. Propodeal spines reduced to small denticles. Petiolar node (in dorsal view) approximately square.

Measurements. Worker (n = 22). CI 84-92; EI 21-27; EL 0.19-0.27; HL 0.88-1.29; HW 0.75-1.16; ML 1.23-1.84; MTL 0.77-1.08; SI 104-126; SL 0.94-1.28.

Comments. Aphaenogaster mediterrae  HNS  is found in mallee and open woodlands from the Adelaide region west across the Nullabor Plain to south-central Western Australia (Fig. 28). Nests are generally in sand with cone or funnel-shaped entrances. This species was previously confused with A. barbigula  HNS  .
