TYPES: Female holotype and male allotype taken in pitfall traps in litter at Gordon,

338449S, 1518099E, New South Wales (July 8–29, 1982; C. Horseman), deposited in AMS ( KS9743 ) .

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

DIAGNOSIS: Males can be recognized by the spur on the distal side of the embolar base (fig. 422), females by the narrow, beakshaped anterior epigynal hood that is far removed from the posteriorly situated, diamond­shaped atrium (fig. 424).

MALE: Total length 10.0. Abdominal dorsum gray, without pair of transverse white stripes, soft portions of cuticle mottled with white spots, venter pale white, with four longitudinal rows of tiny orange sclerotizations; legs unmarked. Leg spination: femora I–III p0­0­1; tibiae: III v2­2­2, r0­1­1; IV p0­1­1. Retrolateral tibial apophysis relatively short (fig. 423); base of embolus with distinct distal apophysis, embolar apophysis long, tegular apophysis long, median apophysis flattened (fig. 422).

FEMALE: Total length 10.2. Coloration as in male. Leg spination: femora I–III p0­0­1; tibiae: III v2­2­2, r0­1­1; IV p0­1­1. Epigynal hood narrow, beak­shaped (fig. 424); dorsalmost ducts greatly widened posteriorly (fig. 425).
