Figures 686–689 ; Map 73

TYPE: Female holotype taken in pitfall trap at Barlee Range Nature Reserve , 238069S, 1168009E, Western Australia (Aug. 1993; S. van Leeuwen, B. Bromilow), deposited in WAM (96/693) .

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: This species seems closest to N. capensis (see above); males have a distinctive prolaterally directed tubercle on the base of the lateral prong of the terminal apophysis (fig. 686), and females have a wid­ er epigynal atrium (fig. 688).

MALE: Total length 3.9. Abdomen light gray, venter with four longitudinal rows of small, circular, orange sclerites. Leg spination typical for genus. Retrolateral tibial apophysis with distinct dorsal protuberance on base (fig. 687); median prong of terminal apophysis with narrow, anteriorly directed tip, lateral prong with narrow, prolaterally directed tip, base of lateral prong with prolaterally directed tubercle (fig. 686).

FEMALE: Total length 4.6. Coloration as in male. Leg spination typical for genus. Epigynal atrium relatively wide, with narrow anteromedian ridge (fig. 688); anterior ducts with posteriorly directed extensions, posterior ducts with anteromedian tubercle (fig. 689).
