TYPE: Female holotype from Lake Gilles Conservation Park , 338049S, 1368419E, South Australia (Apr. 2, 1987; D. Lee, D. Hirst), deposited in SAM ( N1996 /216) .

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

DIAGNOSIS: Males resemble those of L. quinqueplagiata and L. dwellingup in having a large protrusion on the palpal femur, but have the tip of the retrolateral tibial apophysis apically incised and bifid (fig. 203); females also have an arrow­shaped epigynal midpiece similar to that found in those species, but have longer epigynal margins that are less heavily sclerotized anteriorly, and the epigynal midpiece is greatly elevated (fig. 204).

MALE: Total length 8.1. Abdominal dorsum with four indistinct anterior white spots and very distinct posterior white spot situated just over spinnerets; legs unmarked. Palpal femur with large protrusion at base; retrolateral tibial apophysis short, apically incised, producing bifid tip (fig. 203); tegulum greatly expanded, reaching to about fourfifths of tibial length; embolus long, with strong, gently curved tip (fig. 202).

FEMALE: Total length 10.6. Coloration as in male except that all segments of leg I are deeper red than are legs II–IV. Epigynum with narrow, triangular, elevated midpiece and lightly sclerotized, m­shaped margins (fig. 204); spermathecae bulbous, on long, twisted stalks (fig. 205).
