Rebilus grayi , new species Figures 635–638 , 653 ; Map 45

TYPE: Female holotype taken in a pitfall trap set at an elevation of 1180 m at a site 1.3 km S along Bungaree Trail from Barrington Tops Forest Road, Barrington Tops State Forest , 31 ° 56 ̍ S, 151 ° 21 ̍ E, New South Wales (Feb. 4–Apr. 9, 1993; M. Gray, G. Cassis), deposited in AMS (KS42988) .

ETYMOLOGY: The specific name is a patronym in honor of Dr. Michael Gray of the Australian Museum, collector of many interesting gnaphosoids.

DIAGNOSIS: Males and females have not been collected together but are tentatively matched here on the basis of their mutual similarities to those of R. monteithi . Males have a distinctively small, triangular, protuberant basal tibial apophysis (fig. 636); fe­ males have distinctively short and arched anterior epigynal ducts (fig. 638).

MALE: Total length 12. Coloration as in R. lugubris . Leg spination: femora: I–III p1­1­ 0, r0­1­0; IV p1­1­0; tibiae: I, II v1p­2­1p; III v2­2­2; IV v2­2­2, r0­1­1; metatarsi: III p0­0­1, v2­0­2; IV p0­0­1, v0­0­2, r1­0­0. Basal tibial apophysis small, projecting, thumblike, distal apophysis with sinuous dorsal margin, prolateral corner of cymbium with dense, unthickened setae (figs. 636, 653); tegulum globose, tip of terminal apophysis smoothly narrowed (fig. 635).

FEMALE: Total length 14. Coloration as in male. Leg spination: femora: I, IV p1­1­0; II, III p1­1­0, r0­1­0; tibiae: I v1p­1p­1p; II v1p­ 1p­2; III 1p­2­2; IV v2­2­2, r0­1­1; metatarsi: III p0­0­1, v2­0­2; IV p0­0­1, v1p­0­2, r1­0­ 0. Epigynal septum with m­shaped margin situated at about half of epigynal length (fig. 637); anterior ducts very short, arched (fig. 638).

OTHER MATERIAL EXAMINED: New South Wales: Tubrabucca, 31 ° 58 ̍ S, 151 ° 28 ̍ E, Jan. 1948, elev. 4300 ft (AMS KS35550), 2♀. Victoria: Upper Lurg, 36 ° 35 ̍ S, 146 ° 11 ̍ E, Oct. 19, 1994, inside house, on floor (J. Strudwick, CVIC 680), 13.

DISTRIBUTION: If the sexes are correctly matched, the species occurs in Victoria and at high elevations in New South Wales (map 45).
