Type material.

Holotype female (WAM T64748): quadrat 19, Lorna Glen Station, 26°00'05"S, 121°33'48"E, Western Australia, Australia, 1-7.XI.2002, M.A. Cowan, pitfall traps.

Australia: Western Australia: Same data as holotype, 1♀, 3 immatures (WAM T107714); 1♀, 3 immatures, same data as holotype except 5 -14.IV.2002 (WAM T65383); 1 immature, same data as holotype except 13-19.III.2003 (WAM T107715).

Etymology.

The specific epithet is in honor of Julianne Waldock for all of her work on Australian terrestrial invertebrates.

Diagnosis.

Females of this species can be differentiated from others by a well-defined keyhole-shaped median field, and a single genital opening that internally is divided into two copulatory ducts leading to medium-sized oval spermathecae (Figs 43-44). Males unknown.
