Figures 570–573 ; Map 69

TYPES: Female holotype and male allotype taken in pitfall traps at an elevation of 690 m on Rimau Road, c. 11.2 km E Cockerawombeeba Road, Mount Boss State Forest , 318119S, 1528219E, New South Wales (Feb. 4–Apr. 9, 1993; M. Gray, G. Cassis), deposited in AMS ( KS39564 ) .

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

DIAGNOSIS: This species is very close to G. bulga , but males can be distinguished by the longer, narrower median extension on the median apophysis (figs. 570, 571), females by the posteriorly narrower and anteriorly wider epigynal septum (figs. 572, 573).

MALE: Total length 6.4. Coloration as in G. marengo . Leg spination: metatarsi III v2­ 2­0. Retrolateral tibial apophysis bifid, with ventral prong hook­shaped (fig. 571); median apophysis with long, narrow, prolaterally directed extension, retrolateral edges of apophysis rounded (fig. 570).

FEMALE: Total length 7.2. Coloration as in G. marengo . Leg spination: tibiae III v0­2­2. Epigynum with median septum, posterior portion narrow, diamond­shaped, anterior portion almost half width of posterior portion (fig. 572); spermathecae with large anterior extensions (fig. 573).
