Karaops manaayn Crews & Harvey, 2011: 57, figs 47-50, 96 (♂, ♀, examined).

New record.

New South Wales • 1♀; Oxley Wild Rivers National Park, Yarrowitch River; -31.0759, 152.0563; 12 Nov. 2015; H.M. Smith leg.; (AM KS.124572).

Diagnosis.

The spermathecae of Karaops manaayn are further from the midline than are the accessory bulbs ( Crews and Harvey 2011: fig. 48). The male has a sclerotized, quadrangular process on the conductor ( Crews and Harvey 2011: fig. 49).

Description.

The description of the male and female can be found in Crews and Harvey (2011).

Distribution.

Karaops manaayn (Fig. 1G, H ) is found only in a small area near the Macleay and Yarrowitch Rivers, New South Wales (Map 2 ).

Natural history.

This species has been collected in two adjacent subregions: the Macleay Hastings and Coffs Coast and Escarpment subregions of the New South Wales North Coast bioregion. While climate within the entire region ranges from subtropical to subhumid, the climate in the immediate area around Armidale is somewhat temperate ( NSW National Parks and Wildlife Service (2003)) (Suppl. material 2: table S1). This species has been collected on a rock wall above a river and beneath bark.

Discussion.

Karaops manaayn (Fig. 1G, H ) is known only from a small area in northeastern New South Wales, within the range of K. raveni , with which it has been collected (Maps 1 , 2 , 4 ). Another species, K. marrayagong , also occurs within the range of K. raveni , but it is in the Karaops raveni group. Molecular data has placed this species with members of the Central Desert Species group (Suppl. material 1). Although its placement with the group is stable, depending on the analysis, it is unstable within the group (unpubl. data). Morphologically, it also shares similarities with members of this group, such as the large median lobe of the epigyne, and the accessory bulb and spermathecae are connected by a duct with a loop ( Crews and Harvey 2011: figs 47, 48), and the male has a two-branched median apophysis ( Crews and Harvey 2011: fig. 49).
