TYPES: Female holotype and male allotype taken in grass tussocks at Queens Domain, Hobart , 428529S, 1478199E, Tasmania (Mar. 23, 1968; V. Hickman), deposited in AMS ( KS29339 ) .

ETYMOLOGY: The specific name is a noun in apposition taken from Mount Ainslie, one of the localities at which the species has been collected.

DIAGNOSIS: Males can be recognized by the tiny median apophysis situated at the tip of the embolus (fig. 360), females by the distinctive diamond­shaped light area formed within the epigynal midpiece by the outlines of the spermathecae showing through the epigynal cuticle (fig. 362).

MALE: Total length 2.6. Abdominal dorsum dark gray, with three pairs of small white cardiac spots (anterior and part of median pair obscured by scutum) and series of posterior white hairline chevrons; legs unmarked. Palpal femur arched but unmodified; retrolateral tibial apophysis tiny, triangular (fig. 361); cymbium with dorsodistal scopula; tegulum globose, reaching to about onethird of tibial length; embolus broadly fused basally to tegulum, tip short, twisted prolaterally; median apophysis short, hook­shaped, distally situated (fig. 360).

FEMALE: Total length 3.8. Coloration as in male. Palpal tarsus shortened, thickened at about half its length, with dorsodistal scopula. Epigynum with pair of semicircular lateral margins (fig. 362); spermathecae bipartite, anterior portion on twisted duct (fig. 363).
