TYPES: Female holotype and male allotype taken in pitfall traps set at an elevation of 770 m along Mount Allyn Road, 2.3 km N of Shellbrook Forest Road, Chichester State Forest , 31 ° 52 ̍ S, 151 ° 27 ̍ E, New South Wales (Feb. 4–Apr. 9, 1993; M. Gray, G. Cassis), deposited in AMS (KS404034) .

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: This appears to be the northern sister species of T. turramurra , and the two species are quite similar, sharing a serrate embolus. Males of this species have a shorter embolus and a shorter retrolateral prong on the median apophysis (fig. 293); females have a deep, triangular epigynal atrium with the septum reduced to a narrow anterior ridge (fig. 295) and much wider median epigynal ducts (fig. 296).

MALE: Total length 4.4. Coloration as in T. sculptilis except posterior femora darkened laterally, posterior patellae only slightly darkened proximally. Legs spineless. Palpal femur with only slight ventral enlargement at distal end; retrolateral tibial ridge­shaped, bifid (fig. 294); tip of cymbium not greatly elongated, but forming functional conductor (fig. 293).

FEMALE: Total length 5.3. Coloration and legs as in male. Epigynum with deep, anteriorly narrowed atrium (fig. 295), epigynal ducts expanded, recurved anterolaterally (fig. 296).
