Type material.

Holotype female (WAM T97214): site 5, Badgeradda Range, Muggon Station, 26°46'01.6"S, 115°32'54.4"E, Western Australia, Australia, 18.III.2009, S.C. Crews, M.C. Murrmann, under rocks.

Other material examined.

AUSTRALIA: Western Australia: collected with holotype, 2♀ (WAM T97213, T97215); Muggon Station, site MUG 9, 26°49'03"S, 115°32'56"E, 20-28.X.2003, A. Desmond, M. Cowan, dry pitfall, 1 immature (WAM T95019); Muggon Station, site MUG 5, 26°46'S, 115°33'E, 20-28.X.2003, A. Desmond, M. Cowan, dry pitfall, 2 immatures (WAM T95020).

Etymology.

The specific epithet comes from the type locality. The name is to be treated as a noun in apposition.

Diagnosis.

This species can be separated from all other species by genitalic characteristics, including a bilobed sclerotized area covering the copulatory openings located in the posterior third of the epigynal plate (Fig. 33). Males unknown.

Remarks.

Immatures are matched with this species as they were collected from the same locality as the holotype.

Abdomen:terminal setal tufts present. Epigyne:lateral lobes fused, small medial depression in lower third of plate, bilobed sclerotized hood, epigynal pockets absent, copulatory openings located under hood; copulatory ducts in contact medially, then both curve outward, then back inward becoming darker and more sclerotized, then outward again before twisting around to the small ovoid, folded spermathecae, fertilization ducts located posteriorly, small posterodorsal fold present, not covering any part of the internal genital (Figs 33-34).
