Ordo: Araneae
Familia: Selenopidae

Name
Karaops deserticola Crews & Harvey, 2011 sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type material
Holotype female (SAM N199350): Mount Lindsay, South Australia, Australia [27°02'S, 129°53'E], 28.VIII.1980, A. Lees, under rock slab on bare granite slope.
Etymology
The specific epithet comes from the Latin word desertum which is a waste place or a wilderness and is an adjective that denotes the presence of this species in desert biotopes.
Diagnosis
Females can be differentiated from other species by the median septum of the copulatory organs tapering posteriorly, giving it a subtriangular appearance (Fig. 59). Males unknown.
