TYPES: Female holotype and male allotype taken in pitfall traps at an elevation of 1070 m off Cunnawarra Trail, c. 2 km N Cunnawarra Creek, Styx River State Forest , 308329S, 1528209E, New South Wales (Feb. 4–Apr. 9, 1993; M. Gray, G. Cassis), deposited in AMS ( KS35371 ) .
ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.
DIAGNOSIS: This species seems closest to G. marengo but can be distinguished by the basally enlarged median prong on the median apophysis (fig. 546) of males, and the longer epigynal ducts (fig. 549) of females.
MALE: Total length 5.8. Coloration as in G. marengo . Leg spination: tibiae III v222. Retrolateral tibial apophysis bifid, with ventral prong hookshaped (fig. 547); median apophysis with long, basally widened medial prong (fig. 546).
FEMALE: Total length 6.5. Coloration as in G. marengo . Leg spination typical for genus. Epigynum wide, anterior onethird divided by septum (fig. 548); spermathecae each with anterior accessory lobe situated posterior of their tip (fig. 549).
