Hairs on venter of head randomly distributed and not forming a distinct psammophore (Fig. 10); posterior margin of head broadly arched in full face view (Fig. 9); shorter erect hairs on mesosomal dorsum(especially those on mesonotum) with blunt tips; propodeal spines long, the dorsal surfaces of propodeum and propodeal spines connected through a gentle concavity (so that the base of each spine is at approximately the same level as the dorsal surface of the propodeum) (Fig. 10). The long scapes and blunt mesonotal hairs will separate this species from near relatives.  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 andlateral margins forming a continuous surface). Hairs on venter of head randomly distributed and not forming a distinct psammophore. Mandibular sculpture composed of regularly sized striations. Shorter erect hairs on mesosomal dorsum (especially those on mesonotum) with blunt tips. Propodeal spines intermediate in length. Dorsal surfaces of propodeum and propodeal spines connected through a gentle concavity (so that the base of each spine is at approximately the same level as the dorsal surface of the propodeum). Petiolar node (in dorsal view) approximately square.  FIGURES 19-20.

Scape length versus head width measurements for A. pythiaand A. reichelae.  Comments. This is one of the most commonly encountered species of Aphaenogasterin Australia. It occurs in a wide range of habitats from swampy coastal scrub, wet sclerophyll and rainforests through to dry sclerophyll and Callitris woodlands. Nests in sandy soil are often highly visible with large, funnel-shaped entrances while nests in firmer soils are less obvious with low, scattered soil around entrances. Nests are also found under rocks or other objects on the ground. Activity around nests is generally restricted to a few workers excavating soil or defending the nest entrance. Foraging activity seems to be limited with workers foraging singly and primarily near the nest. This species has an extensive literature, including the following: Banks (1916) (association with mites), Crawley (1922a: 122) (biology), Barrett (1927) (habits, as A. longipes[sic]), Clark (1929: 121) (distribution), Clark (1934: 58) (distribution), Smith and Atherton (1944: 4) (biology, economic importance), Sloane and Sloane (1964) (nesting biology), Berg (1975) (seed dispersal), Imai, Crozier and Taylor (1977) (karyotype), Greenslade and Thompson (1981) (biology), Humphreys (1981) (relation to soils), Humphreys and Mitchell (1983) (relation to soils), Cowan et al. (1985) (relation to soils), Andersen (1988a) (relation to fire), Anderson (1988b) (relation to plants), Hughes and Westoby (1992a) (seed dispersal), Hughes and Westoby (1992b) (seed dispersal), Nicholls and McKenzie (1994) (distribution pattern) and York (1994) (relation to fire). Emery's (1921) A. flavais here treated as a junior synonym of A. longiceps. A. flavawas established by indication based on a male from Queensland and figured in Emery (1914). Emery (1914) presented two figures, one identified as longicepsfrom Queensland and the other as longiceps ruginotafrom Sydney. Emery (1921) based flavaon the figure of longiceps. Wheeler (1916) (before Emery established flava) stated that the differences between these males were "insignificant" and considered them to belong to the same taxon, longiceps(he considered ruginotato be a synonym of longiceps, a treatment supported during this study); he also mentions that the male of pythiais quite different. Unfortunately Emery (1921) gave no information on why he considered flavato be a distinct taxon.  FIGURES 24-29. Distribution of material examined during this study: Fig. 24, A. barbara; Fig. 25, A. barbigula; Fig. 26, A. kimberleyensis; Fig. 27, A. longiceps; Fig. 28, A. mediterrae; Fig. 29, A. poultoni.   FIGURES30-31. Distribution of material examined during this study: Fig. 30, A. pythia; Fig. 31, A. reichelae. In fact the males of longicepsand pythiaare very similar, differing mainly in colour and size (being larger and darker in longiceps). The male of barbara, the only other species of Aphaenogasterknown from Queensland, differs from both longicepsand pythiain lacking a metanotal groove and in having the occipital collar rounded. The males of both longicepsand pythiahave distinct, angular metanotal grooves and the occipital collars are angular. What Wheeler (1916) considered to be the male of pythiamay well have actually been the male barbara. Emery's (1914) illustration of longicepsgives little hint as to whether this male belongs to longicepsor pythia, although barbaracan be safely eliminated. The shape of the head does differ slightly between longicepsand pythia, and Emery's figure resembles longicepsmore closely than pythia. Based on this flavais here treated as a synonym of longicepsrather than pythia. It should be noted that the name flavawas overlooked for 74 years, until Bolton (1995) drew attention to it in his world catalogue. The name's obscurity was due to the cryptic way in which it was established. The name was based on a scant two lines of text, one consisting of " flava, Emery" and a second with a reference to Emery (1914). It is easy to see why the name was overlooked for such an extended period of time.
