Karaops alanlongbottomi Crews & Harvey, 2011: 32, figs 17, 18 (♂, examined).

Diagnosis.

Karaops alanlongbottomi can be differentiated from other species of the Kimberley group by the conductor and the median apophysis. Distally, the conductor is very narrow and extends retrolaterally beyond the edge of the cymbium ( Crews and Harvey 2011: fig. 17). Additionally, the median apophysis is very small and narrow, and the tegular lobe is almost non-existent.

Description.

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

Female. Unknown.

Distribution.

Known from only the type locality, Degerando Island, Champagny Islands, Western Australia (Map 7 ).

Natural history.

Nimemba (Degerando Island) is a small island (1337 ha) of the Champagny Islands in the Bonaparte Archipelago. It is in the Mitchell subregion of the Northern Kimberley bioregion. The climate is tropical monsoonal. While there are plants and animals of special interest in the subregion, very little is known of the terrestrial arthropod fauna, and there have been no systematic surveys of flora or fauna in the area. Some of the islands are even free of invasive animal species and uninhabited by humans. Thus, they are likely to harbor unique species. The single adult male was collected in July, in the dry season (Suppl. material 2: table S1).

Discussion.

The holotype (Fig. 16D ) was collected on the northwest tip of the island, and there are not many rocks or much vegetation. The island is low elevation and will be affected by sea level rise due to climate change. The female remains unknown.
