Karaops marrayagong sp. n. Figs 27-28Map 7

Type material.

Holotype female (AM KS19743): Kitty’s Creek [33°47'S, 151°08'E], near Sydney, New South Wales, Australia, 1916.

Etymology.

The specific epithet comes from the indigenous Dharug word for spider. Dharug is the language indigenous to the type locality. The name is to be treated as a noun in apposition.

Diagnosis.

This species can be separated from Karaops raveni sp. n. as the lateral lobes of the epigyne do not come into contact posteriorly, the ducts are narrower, and the spermathecae are closer together (Figs 27-28). Males unknown.

Remarks.

There is some ambiguity as to where exactly this specimen is from as it is rather old. The region of Kitty’s Creek in Sydney has been searched recently, but the area has been developed a great deal since the specimen was originally collected.
