Rebilus bulburin , new species Figures 583–586 , 640 ; Map 45

TYPE: Female holotype taken by pyrethrum knockdown in a rainforest at an elevation of 600 m in Bulburin State Forest , 9 km E Many Peaks, 24 ° 30 ̍ S, 151 ° 35 ̍ E, Queensland (Sept. 10, 1989; G. Monteith), deposited in QMB ( S30343 ) .

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

DIAGNOSIS: Males closely resemble those of R. lugubris but have a much smaller tegulum without a pronounced bulge at the prolateral side of the palpal bulb (fig. 583); females have an arched anterior epigynal margin situated far from the anterior ends of the epigynal ducts (figs. 585, 586).

MALE: Total length 8. Carapace light brown, darkest laterally; abdomen pale gray with darkened cardiac mark and lighter, longitudinal pale stripes on each side of cardiac mark; legs light brown, metatarsi darkest. Leg spination: femora I, II p1­1­0; tibiae I– IV v1p­1p­2; metatarsi: III v2­0­0; IV v0­0­ 1p. Retrolateral tibial apophysis short, triangular, dorsally rebordered, situated opposite dense patch of thickened setae situated at proximal prolateral corner of cymbium (figs. 584, 640); median apophysis relatively wide, sharp at tip, tip of conductor relatively long, narrow (fig. 583).

FEMALE: Total length 18. Coloration as in R. lugubris . Leg spination: femora: I–III p1­ 1­0, r0­1­0; IV p1­1­0; tibiae: I, II v1p­3­2; III, IV v2­2­2; metatarsi: III v2­0­0; IV v0­ 0­ 1p. Epigynal ducts relatively short, not extending near arched anterior margin of epigynum (fig. 585); anterior portion of ducts occupying about one­third of epigynal length (fig. 586).
