Type material.

Holotype female (AM KS43756): Kempsey Road, West of Armidale, above Macleay River [30°39'S, 152°12'E], New South Wales, Australia, 15.IV.1992, J. Frazier, on rock wall above river. Paratype: Armidale-Kempsey Road above Macleay River, 30°44'52.6"S, 152°14'31.2"E, New South Wales, Australia, 26.II.2009, S.C. Crews, H. Smith, under bark, 1♂ (AM KS113351).

Etymology.

The specific epithet comes from the word for spider, manaayn, in the indigenous language of the Dhangatti people that inhabit the Macleay Valley. The name is to be treated as a noun in apposition.

Diagnosis.

Females can be differentiated from all other species by having a large quadrangular medium septum (Fig. 47). Males can be differentiated from all other species by having a very large MA that is partially covered by the base of the embolus, as well as a quadrangular projection terminally on the conductor (Fig. 49).
