Karaops umiida Crews, 2013: 447, figs 1, 2. (♀, examined; males mismatched, see below).

Diagnosis.

In light of the new species described here, a new diagnosis is provided. This species can be distinguished from all other members of the group by the genitalia. On the epigyne, the atrium where the copulatory openings are located is u-shaped. The copulatory ducts are directed posterolaterally and there is no larger receptacle between them. The accessory bulbs do not extend anteriorly past the small atrium leading to the ducts. In Crews 2013 (fig. 2), the accessory bulbs were incorrectly labeled as the spermathecae.

Description.

The description of the female can be found in Crews (2013).

Male. Unknown.

Distribution.

Known from only the type locality, Irvine Island, in the Buccaneer Archipelago, Western Australia (Map 7 ).

Natural history.

The specimen was collected in the cooler, drier time of the year, under rocks on boulder scree during the day. Irvine Island is located in the Mitchell subregion of the Northern Kimberley bioregion. It is savannah woodland with small patches of monsoonal rainforest in the region, and the climate is hot tropical with lots of rain in the wet season (Suppl. material 2: table S1).

Discussion.

The holotype (Fig. 18G ) is from Irvine Island. Two males were collected nearby with a label indicating they had been collected on Margaret Island, though the coordinates placed them on Conilurus Island, and this is where they were actually collected (R. Teale, pers. comm.). Due to proximity and general similarities of the habitus of the three specimens, the males were described as Karaops umiida . Recent targeted collecting, however, has uncovered a sizeable species radiation in the Kimberley, and the distribution and phylogenetic relationships of these species indicate there are more to come (Figs 20D, E , 26D , Suppl. material 1, Map 7 ). In a molecular analysis of Karaops species (Suppl. material 1), the holotype female of K. umiida from Irvine Island is not recovered with the males from Conilurus Island. The males are recovered near K. dalmanyi sp. nov. but are morphologically different. Based on these data, the males of K. umiida were misidentified and considered to be unknown, and the males previously misidentified as K. umiida are now K. conilurus sp. nov. Although Conilurus Island is nearby to Irvine Island, they are on different geological formations.
