Cephalic region well FIGURE. 1.

defined, ALE clearly larger than AME. Labium. About as long as wide with symmetrical sinusoidal ridge basally at constriction, ridge more sclerotised on outer edges. Maxillae. Short, narrower basally but cylindrical, with groove extending from point of labium ridge parallel to posterior edge to ca. 0.4 of maxillae. Sternum. Cordate with intercoxal corners. Trochanters deeply notched. Scopula . All leg tarsi with scopula of long setae, not so dense as to obscure cuticle, that on IV divided with band of 2 lines of setae. Metatarsi, full for I, II, thinner basally; distal two-thirds of III, IV and in 3 bands, pro- and retroventral and ventral. None on palp. Legs. I: 2.50, 1.38, 1.88, 1.50, 1.07, 8.31.

IV with 2 small teeth; I with 3–4; 6 on palpal claw. Tufts with dense pads not obviously separated. Spines. I: fe p2d2; pa0; ti v2.2; me v2 not strong. II: fe p2d2; pa0; ti v1.1; me v2. III: fe p2d3r1; pa0; ti p2r 2v 2.2 (or v1.2.2 weak); me p2r 1v 2.1. IV: fe p1d3r1; ti p2d2r 2v 1.2.2; me p5r 5v 3.1. Palp: fe d1.2; pa p1 d1 + apical 1; ti p3r2; ta p3r 3 v 2 apical. Spinnerets (Fig. 1d). Closely set; ALS ca. length of PLS; ALS tip domed, PLS longer, triangular. PMS & PLS appear to have large spigots, PMS with small spigot. Epigyne (Fig. 1e). Externally a medial triangular broad septum with lateral "wings".

Male. Unknown.

Distribution and Habitat. Known only from the southwest of the Western Australian Goldfields at Boorabbin and Buningonia Springs, an area of spinifex and heath.
