TYPE: Female holotype taken in a pitfall trap at C. Hollins on Mount Chalmers, 238189S, 1508389E, Queensland (Mar. 16, 1993; D. Wallace), deposited in QMB ( S22184 ) .

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

DIAGNOSIS: Both sexes can be recognized by their distinctively dark coloration, males by the prolaterally hooked tip of the retrolateral tibial apophysis (figs. 102, 103), and females by their heart­shaped epigynal atrium (fig. 104).

MALE: Total length 5.0. Abdominal dorsum almost black, with five white spots reduced to narrow transverse bands; distal portions of femora, all of patellae, all of anterior tibiae, and distal portions of posterior tibiae greatly darkened. Palpal femur darkened throughout its length but otherwise unmodified; tip of retrolateral tibial apophysis hooked prolaterally (fig. 103); tegulum expanded, reaching to about one­third of tibial length, embolus hidden in ventral view by sclerotized prolateral rim of conductor (fig. 102).

FEMALE: Total length 5.4. Coloration as in male. Epigynum with large, posteriorly situated, heart­shaped atrium (fig. 104); spermathecae tripartite, posterior portions long, narrow (fig. 105).

OTHER MATERIAL EXAMINED: The male associated with the holotype was taken in litter at Homevale, 218249S, 1488339E, April 1–7, 1975 (V. Davies, R. Kohout, QMB S25979 ).
