Figures 574–577 ; Map 70

TYPE: Male holotype taken in a pitfall trap at an elevation of 730 m on Bobbin Fire Trail, 100 m from Padmans Road , Bulga State Forest , 318379S, 1528109E, New South Wales (Feb. 4–Apr. 9, 1993; M. Gray, G. Cassis), deposited in AMS ( KS39579 ) .

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

DIAGNOSIS: Males and females have not yet been collected at the same sites, but are matched here on the basis of their respective great similarities to those of G. boss ; males have a shorter, narrower median extension on the median apophysis (figs. 574, 575); females have a posteriorly wider and anteriorly narrower epigynal septum (figs. 576, 577).

MALE: Total length 5.7. Coloration as in G. marengo . Leg spination: tibiae III v0­1p­ 2. Retrolateral tibial apophysis bifid, with ventral prong hook­shaped (fig. 575); median apophysis with relatively short, wide, prolaterally directed extension, retrolateral edges of apophysis angular (fig. 574).

FEMALE: Total length 8.3. Coloration as in G. marengo . Leg spination: tibiae III v0­2­2. Epigynum with median septum, posterior portion relatively wide, diamond­shaped, anterior portion much less than half width of posterior portion (fig. 576); spermathecae with large anterior extensions (fig. 577).
