New records.

(These are specimens considered Karaops jaburrara based on molecular and geographic data - see Discussion). Western Australia • 5 imm.; Burrup Peninsula off Burrup Road; 20°39.848'S, 116°44.203'E; 11 May 2016; ~ 39 m; S. Crews, J. DeJong leg.; under rocks; sel_1141-1145; SCC16_021; (WAM T155517-T155521) • 7 imm.; ~ 13.5 km W Wickham, out Cleaverville Road; 20°41.086'S, 117°00.487'E; 11 May 2016; ~ 19 m; S. Crews, J. DeJong leg.; under rocks, on rocks, on ground at dusk; sel_1146-1152; SCC16_022; (WAM T155522-T155528).

Diagnosis.

This species can be differentiated from the other species of the group by the dRTA, which is toothed along the upper margin in ventral view ( Crews 2013: fig. 21).

Description.

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

Female. Unknown.

Distribution.

This species is only known from the type locality in the Pilbara, west of Wickham, Western Australia.

Natural history.

This species occurs in the Chichester subregion of the Pilbara bioregion (Fig. 62F ), which is absurdly diverse in Karaops species (Suppl. material 2: table S1). For details on the subregion, see other species descriptions.

Discussion.

Karaops jaburrara (Fig. 62B ) is only known from a single adult male specimen collected in an ethylene glycol pitfall trap that was out for 15 months. Thus, there is no way to know when the animals are active or adults. Other species collected nearby are known from males or males and females, so this is not a case of an unmatched sex. Rearing juveniles from the collection localities failed. Molecular data indicate that juvenile specimens collected in the area form a clade, and even though there are other species that have been found nearby, none have been found at these particular localities (Suppl. material 1). Because of this, it is believed that these specimens are indeed K. jaburrara , and records are given above.
