Figures 210–213 ; Map 23

TYPE: Female holotype from Mount Eba Station, 308119S, 1358409E, South Australia

(May 25–26, 1956; G. Gross), deposited in SAM ( N1996 /223).

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

DIAGNOSIS: Males resemble those of L. hirsti in having a lateral protrusion on the retrolateral tibial apophysis, but lack the distinct protuberance on the palpal femur found in that species (fig. 211); female also resemble those of L. hirsti but have an anteriorly narrowed epigynal midpiece and relatively longer posterior portions of the spermathecae (fig. 213).

MALE: Total length 4.6. Abdominal dorsum as in L. cylindrata ; anterior femora darkened distally, anterior tibiae darkened laterally, posterior patellae and tibiae darkened laterally. Palpal femur without basal protrusion on ventral surface; retrolateral tib­ ial apophysis with retrolaterally directed protrusion below tip (fig. 211); tegulum slightly expanded, reaching to about one­fifth of tibial length; embolar base short, wide, tip arched (fig. 210).

FEMALE: Total length 8.3. Coloration as in male. Epigynal midpiece not extending as far anteriorly as spermathecae, narrowed anteriorly, otherwise as in L. hirsti (fig. 212); spermathecae bipartite, posterior portions longer than in that species (fig. 213).

OTHER MATERIAL EXAMINED: South Australia: 2 km ENE The Coffins Dam , 338249S, 1398349E, Oct. 21, 1992, pitfall ( SAM N1996 / 315), 1 ?; Lake Gilles , 328419S, 1368559E, Feb. 1993, under plank at lake edge (P. Hudson, SAM N1996 /215), 1 /.
