Figures 486–489 ; Map 56

TYPE: Female holotype taken at an elevation of 700 m on Mount Macedon , 378259S, 1448359E, Victoria (Nov. 30, 1996; N. Platnick, R. Raven, V. Ovtsharenko, K. Catley), deposited in QMB .

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 here on the basis of similarities in size and coloration. Males can easily be recognized by the sinuous and basally expanded retrolateral tibial apophysis (fig. 487), females by the circular epigynal margins (fig. 488).

MALE: Total length 5.7. Dorsum of abdomen with transverse white stripe covered by extensive scutum extending back to about two­thirds of abdominal length; coloration otherwise as in C. keira . Leg spination: femora: II p0­0­0; III p0­0­0, r0­0­0; IV r0­0­0; tibiae III, IV p0­1­1, v2­1p­2, r0­1­1; metatarsi III, IV p0­1­1, v2­1p­1p, r0­1­1. Retrolateral tibial apophysis almost bipartite, dorsal portion short, with rounded ledge, ventral portion long, sinuous (fig. 487); embolar apophysis short, small, tegular apophysis with long, rounded apical projection, median apophysis relatively small, simple, hookshaped (fig. 486).

FEMALE: Total length 6.9. Abdominal dorsum without scutum, coloration otherwise as in male. Leg spination: femora: I, II p0­0­0; III p0­0­0, r0­0­0; IV r0­0­0; tibiae: III p0­ 1­1, r0­1­1; IV p0­0­0, r0­1­1; metatarsi III, IV p0­1­1, r0­1­1. Epigynal margins forming full circle, atrium with narrow median septum (fig. 488); lateral ducts enlarged anteriorly (fig. 489).

OTHER MATERIAL EXAMINED: New South Wales: 0.7 km W Omadale Brook Road along unnamed logging track, Stewarts Brook State Forest, 318549S, 1518239E, Feb. 4–Apr. 9, 1993, pitfall, elev. 1250 m (M. Gray, G. Cassis, AMS KS37393 ), 1?. Victoria: Cobon North Coupe , 378229S, 1488569E, Apr. 6–10, 1992, pitfall, midslope (R.

Coy, NMV K3548 ), 1 ?; Rich­Murrungowar Coupe , 378349S, 1488389E, Mar. 16–24, 1992, pitfall, midslope (R. Coy, NMV K3541 ), 1 ?; Separation Creek , 388389S, 1438549E, Sept. 19 –21, 1989, under eucalypt bark (M. Harvey, M. Blosfelds, WAM 1996 /202), 1 /.
