Figures 166–169 ; Map 16

TYPE: Female holotype taken in pitfall trap at an elevation of 970 m along Mount Allyn Road, adjacent to Mount Allyn Forest Park, 900 m from junction of Mount Allyn Lookout Road, Chichester State Forest, 328079S, 1518259E, New South Wales (Feb. 4–Apr. 9, 1993, M. Gray, G. Cassis), deposited in AMS (KS40486).

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

DIAGNOSIS: This species resembles other members of the pusilla group in the shape of the male retrolateral tibial apophysis and epi­ gynum, but can be distinguished in males by the more dorsally situated and directed retrolateral tibial apophysis (fig. 167) and in females by the broad posterior portion of the spermathecae (fig. 169).

MALE: Total length 5.2. Abdominal dorsum with median row of dark markings separated by white areas from dark rows of markings on side of abdomen; legs with patellae lighter than other segments, posterior tibiae with proximal and distal dark rings. Palpal femur with long, low ventral protuberance bearing long, stiff setae; retrolateral tibial apophysis long, narrow, straight, situated near dorsal side of segment (fig. 167); tegulum relatively small, scarcely protruding past base of tarsus; embolar base almost fused to tegulum (fig. 166).

FEMALE: Total length 6.5. Coloration as in male except abdominal dorsum with few white paramedian markings. Epigynum excavate, v­shaped median plate with elevated anterior margins (fig. 168); posterior portion of spermathecae wide, distal portion reduced to tiny lobe (fig. 169).
