Ordo: Araneae
Familia: Selenopidae
Genus: Karaops
Name
Karaops manaayn Crews & Harvey, 2011 sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
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).
