TYPE: Female holotype taken in rainforest on Lamington Plateau , 28 ° 19 ̍ S, 153 ° 04 ̍ E, Queensland (Apr. 2, 1975; R. Raven), deposited in QMB ( S28454 ) .

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

DIAGNOSIS: Males resemble those of R. lugubris in having an expanded tegulum, but can be recognized by the lobate tip of the palpal conductor (fig. 607) and the long expansion on the retrolateral margin of the cymbium (fig. 608); females can be recognized by the long, u­shaped posterior epigynal margin, which occupies about half the epigynal length (fig. 609).

MALE: Total length 16. Coloration as in R. lugubris . Leg spination: femora I–IV p1­1­0; tibiae III, IV v2­2­2; metatarsi: III v2­0­2; IV v0­0­ 1p. Retrolateral tibial apophysis small, triangular, sinuous (figs. 608, 646); cymbium without prolateral thickened setae, with retromarginal expansion, conductor with lobate tip (fig. 607).

FEMALE: Total length 21. Coloration as in male. Leg spination: femora I–IV p1­1­0; tibiae: I, II v1p­3­2; III v2­2­2; IV v2­2­2, r0­ 0­1; metatarsi: III p0­0­2, v2­0­2; IV p0­0­1, v0­0­2. Epigynum with deeply depressed atrium outlined by long, u­shaped posterior margin (fig. 609); secondary spermathecal bulbs directed anterolaterally (fig. 610).

OTHER MATERIAL EXAMINED: New South Wales: Newcastle, 32 ° 55 ̍ S, 151 ° 45 ̍ E (de Castlenau, MNHN), 1♀ ; Richmond Range State Forest , 28 ° 20 ̍ S, 152 ° 55 ̍ E, Apr. 17–18, 1976, open forest (R. Raven, QMB S26430 ), 13 ; Stotts Island, Tweed River, 28 ° 14 ̍ S, 153 ° 31 ̍ E, Nov. 18, 1978, rainforest litter (R. Raven, QMB S28466 ), 1♀. Queensland: near Lamington National Park , 28 ° 16 ̍ S, 153 ° 10 ̍ E, July 10, 1977, under corrugated iron (R. Raven, QMB S26446 ), 1♀ .

DISTRIBUTION: Known only from southeastern Queensland and northern New South Wales (map 46); the Newcastle record from the last century probably refers only to the port from which the specimen was shipped, and that record is not mapped.
