TYPES: Female holotype and male allotype taken in a pitfall trap set in litter at Gleneagle State Forest , 328159S, 1168109E, Western Australia (Jan. 24–Mar. 3, 1979; M. Gray), deposited in AMS ( KS15057 ) .

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

DIAGNOSIS: This species can easily be separated from all other lamponines by the white cuticular scales on both the carapace and abdomen (fig. 276); the tiny, sharply pointed retrolateral tibial apophysis of males (fig. 331) and the rectangular epigynal midpiece of females (fig. 332) are also diagnostic.

MALE: Total length 3.5. Dorsum of abdomen gray, with anterior and median pairs of narrow, transverse, lateral white markings and posteromedian white spot; femora, patellae, and tibiae with dusky sides. Palpal femur short, thick, with slight ventral invagination at about one­third its length; retrolateral tibial apophysis small, short, sharply pointed (fig. 331); embolar base long, basally wide (fig. 330).

FEMALE: Total length 4.7. Coloration as in male. Epigynal midpiece rectangular (fig. 332); spermathecae almost triangular, with small anterior extensions (fig. 333).
