TYPES: Female holotype and male allotype taken under Eucalyptus regnans bark at Cumberland Falls, 378349S, 1458539E, Vic­ toria (May 27, 1991; M. Harvey, M. Blosfelds), deposited in WAM (95/1006, 1007) .

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

DIAGNOSIS: Males of this species resemble those of L. fife in having many setae on the retrolateral tibial apophysis (largely omitted from fig. 219 so that the apophysis shape can be seen) but can be distinguished by the abrupt subdistal narrowing of that apophysis (fig. 219); females can be recognized by the pronounced lateral epigynal margins and triangular median portions of the spermathecae (figs. 220, 221).

MALE: Total length 6.9. Dorsum of abdomen with one pair of anteromedian and three pairs of posteromedian light chevrons (as in fig. 44); posterior femora, tibiae, and metatarsi with distal dark rings, tibiae with slightly darkened proximal ring as well. Palpal femur darkened, sinuous, but without distinct ventral protrusion; retrolateral tibial apophysis with wide rectangular base and hooklike tip, dorsally with stiff setae (fig. 219); tegulum globose, extending to about one­half of tibial length; conductor extending to prolateral side of embolus (fig. 218).

FEMALE: Total length 7.9. Coloration as in male, except anteromedian abdominal light chevron larger. Epigynum with distinct lateral margins, with median depression between anterior ends of lateral margins (fig. 220); spermathecae tripartite, median part largest (fig. 221).
