Austrammo rossi , new species Figures 28–31 ; Map 2

TYPE: Female holotype taken at an elevation of 100 m at Windjana Gorge , 17 ° 25 ̍ S, 124 ° 55 ̍ E, Western Australia (Oct. 17, 1962; E. Ross, D. Cavagnaro), deposited in CAS .

ETYMOLOGY: The specific name is a patronym in honor of the collector of the holotype.

DIAGNOSIS: The single known male and female are from widely separated localities, but are tentatively matched here in accordance with the null hypothesis strategy outlined by Platnick (2000). Males can easily be distinguished from congenerics by their very short retrolateral tibial apophysis (fig. 29), females by having the lateral epigynal margins connected to the anterior epigynal hood (fig. 30).

MALE: Total length 4.3. Leg spination: femur IV p0­0­0, r0­0­1; tibiae: III v0­1p­2; IV p0­0­1, v0­1p­2; metatarsi III, IV p0­1­2. Retrolateral tibial apophysis very short, hooked (fig. 29); embolus relatively short, wide (fig. 28).

FEMALE: Total length 6.4. Carapace yellow, abdominal dorsum pale yellow, venter white, legs pale yellow. Leg spination: femur IV p0­0­0, r0­0­1; tibiae: III v1p­2­2; IV p0­ 1­1, r0­0­1; metatarsi: III p0­0­1; IV r0­0­2. Epigynal hood large, arch­shaped, connected via lateral epigynal margins to margins of median septum (fig. 30); spermathecae bipartite (fig. 31).

OTHER MATERIAL EXAMINED: Western Australia: Nerren Nerren Station, 27 ° 00 ̍ S, 114 ° 32 ̍ E, Jan. 11–May 11, 1995, pitfall (P. West, WAM 99/408), 13.

DISTRIBUTION: Known only from Western Australia (map 2).
