TYPE: Female holotype collected at night in rainforest at Pilgrim Sands, Cape Tribulation , 16 ° 05 ̍ S, 145 ° 26 ̍ E, Queensland (Aug. 24–29, 1988; R. Raven, J. Gallon, T. Churchill), deposited in QMB ( S13982 ) .

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

DIAGNOSIS: Males can be recognized by the long, narrow retrolateral tibial apophysis (fig. 588) and the oppositely directed tips of the median apophysis and conductor (fig. 587), females by the narrow, median posterior epigynal margin and paired anterolateral epigynal margins (fig. 589).

MALE: Total length 8. Carapace reddish brown, darkened laterally; abdomen light gray except most of dorsum pale white; legs light brown, distal tips of patellae and tibiae darkened. Leg spination: femora II, III p0­0­ 0; tibiae: I, II v1p­2­0; III, IV v1p­1p­1p; metatarsi: III v2­0­1p; IV v0­0­ 1p. Retrolateral tibial apophysis relatively long, smoothly narrowed toward tip (figs. 588, 641); cymbium without prolateral thickened setae, median apophysis and conductor with tips directed in opposite directions (fig. 587).

FEMALE: Total length 9. Coloration as in male. Leg spination: femora: I d1­0­0; II, III p0­0­0; tibiae: I, II v1p­2­0; III, IV v1p­1p­ 1p; metatarsus III v1p­0­0. Anterior epigynal margin sclerotized only along anterolateral corners, posterior margin narrow (fig. 589), secondary spermathecal bulbs tiny, situated laterally (fig. 590).
