TYPE: Male holotype taken at an elevation of 750 m at Wombat Creek, 6 km NE Pic­

cadilly Circus , 35 ° 19 ̍ S, 148 ° 51 ̍ E, Australian Capital Territory (Feb. 1984; J. Lawrence, Weir, Johnson), deposited in ANIC .

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

DIAGNOSIS: Males resemble those of T. bondi in having the basal portion of the retrolateral tibial apophysis directed dorsally (fig. 174), but have a prolaterally situated embolus (fig. 173); females have not been collected with males, but also closely resemble those of T. bondi , differing primarily in the relative width of the epigynum (fig. 175) and the longer epigynal ducts (fig. 176).

MALE: Total length 2.8. Carapace light brown, abdominal dorsum dark gray with pair of transverse white marks at about half of length, those marks continuing around sounds to dark gray venter; legs as in T. bondi but posterior legs less distinctly bicolored. Leg spination typical for genus. Basal portion of retrolateral tibial apophysis directed dorsally, distal portion appearing as translucent flange (fig. 174); embolus relatively long, situated prolaterally (fig. 173).

FEMALE: Total length 2.5. Carapace dark brown, coloration otherwise as in male. Leg spination: tibia IV v1p­0­0. Epigynum slight­

ly wider than long (fig. 175), posterior portion of epigynal ducts expanded, interpolated between anterior portions (fig. 176).

OTHER MATERIAL EXAMINED: Australian Capital Territory: Piccadilly Circus, 35 ° 22 ̍ S, 148 ° 48 ̍ E, Mar. 1984, elev. 1240 m (J. Lawrence, T. Weir, M. Johnson, ANIC), 13.
