Rebilus brooklana , new species Figures 615–618 , 648 ; Map 45

Rebilus lugubris (misidentification): L. Koch, 1875: 621 (female paralectotype, presumably from Sydney, in ZMB, examined).

TYPES: Female holotype and male allotype from Brooklana , E of Dorrigo, 30 ° 16 ̍ S, 152 ° 53 ̍ E, New South Wales (July 1929; W. Heron), deposited in AMS (KS35523) .

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

DIAGNOSIS: Males resemble those of R. lugubris and R. bulburin but lack enlarged setae at the base of the prolateral side of the cymbium as well as a prolateral cymbial expansion (figs. 615, 616, 648); females have a u­shaped epigynal septum and anteriorly widened anterior epigynal ducts (figs. 617, 618).

MALE: Total length 10. Coloration as in R. lugubris . Leg spination: femora: I p1­1­0; II p1­1­0, r0­1­0; III p1­1­0, r1­1­0; IV p1­0­0; tibiae: III v1p­2­2; IV v2­2­2, r0­1­1; metatarsi: III p0­0­1, v2­0­2; IV p0­0­1, v0­0­1p, r1­0­0. Basal tibial apophysis relatively low, gently rounded, distal apophysis triangular, laterally excavated (figs. 616, 648); tip of terminal apophysis long, spiralled behind tip of conductor (fig. 615).

FEMALE: Total length 14. Coloration as in male. Leg spination: femora I–IV p1­1­0; tibiae: III v2­2­2; IV v2­2­2, r0­1­1; metatarsi: III p0­0­1, v2­0­2; IV p0­0­1, v0­0­1p, r1­0­ 0. Epigynum with septum u­shaped, restrict­ ed to anterior half of epigynal length (fig. 617); anterior ducts widened anteriorly (fig. 618).

Koch, 1875: 622) .

Rebilus bilpin , new species

Figures 619–622 , 649 ; Map 48

TYPE: Female holotype taken under rock at Bilpin , 33 ° 03 ̍ S, 150 ° 31 ̍ E, New South Wales (July 8, 1972; M. Gray), deposited in AMS (KS35517) .

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

DIAGNOSIS: Males and females have not been collected together but are tentatively matched by their mutual resemblances to those of R. lugubris and R. bulburin ; males of all three species have enlarged setae at the prolateral basal corner of the cymbium, but those of R. bilpin differ in having a distinct prolateral prong at the dorsal tip of the retrolateral tibial apophysis (figs. 620, 649); females also resemble those of R. lugubris and R. bulburin in having arched and divergent anterior epigynal ducts, but have those ducts longer and narrower (fig. 622).

MALE: Total length 16. Coloration as in R. lugubris . Leg spination: femora: I, III, IV p1­ 1­0, r0­1­0; II p1­1­0, r1­1­0; tibiae: I v1p­ 2­1p; III v2­2­2; IV v2­2­2, r0­1­1; metatarsi: III p0­0­1, v2­0­2; IV p0­0­1, v2­0­2, r1­0­ 0. Retrolateral tibial apophysis with distinct prong at dorsal side of tip, situated opposite dense patch of thickened setae situated at proximal prolateral corner of cymbium (figs. 620, 649); distal portion of conductor almost as wide as basal portion (fig. 619).

FEMALE: Total length 15. Coloration as in male. Leg spination: femora: I, II, IV p1­1­ 0; III p1­1­0, r0­1­0; tibiae: I v1p­2­0; II v1p­ 2­1p; III v2­2­2; IV v2­2­2, r0­1­1; metatarsi: III p0­0­1, v2­0­2; IV p0­0­1, v2­0­2, r1­0­ 0. Anterior epigynal margin semicircular (fig. 621); anterior epigynal ducts narrow, arched, strongly divergent (fig. 622).
