Karaops burbidgei Crews & Harvey, 2011: 48, figs 35-28 (♂♀, examined).

Diagnosis.

The males can be differentiated from other members of the group by the large tegular lobe that covers nearly all of the basal part of the cymbium and the spermophor does not come into contact with the lower margin of the lobe ( Crews and Harvey 2011: fig. 35). The female can be differentiated from other species by having short copulatory ducts, and the copulatory openings are located beneath an m-shaped hood in the center of the epigynal plate ( Crews and Harvey 2011: figs 37, 38).

Description.

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

Distribution.

This species is known only from Barrow and Varanus Islands, Western Australia.

Natural history.

Karaops burbidgei (Fig. 48C, D View Figure 48 ) is only known from Barrow Island and Varanus Island. The islands are primarily in the Carnarvon ecoregion in the Cape Range subregion. The south peninsula of Barrow Island is part of the Pilbara bioregion, Roebourne subregion, and no specimens have been collected here, but it is unclear if the area has been searched. Males and females have been collected in both the hotter, wetter season and the cooler, drier season. This species has been collected on or beneath rocks at night and in pitfall traps set around the rocks.

Discussion.

This species is morphologically similar and genetically closely related to Karaops durrantorum sp. nov. (Suppl. material 1). Barrow Island is a land-bridge island, and there have been several fluctuations of sea level connecting and disconnecting it from the mainland. The last time there was a connection to the mainland was 8-10 kya. Sea levels have also caused the island to be divided into smaller islands until ~ 2 kya ( Moro and Lagdon 2013) (Suppl. material 2: table S1).
