Poecilipta carnarvon sp. nov.

( Figs 115a , 116a–c , 135 . Map 73)

Material. Western Australia: holotype ♂, Nerren Nerren Station , 27°03'28.1"S, 114°36'24.8"E, 11 Jan–11 May 1995, NE5, wet pits, P. West et al., WAM / CALM Carnarvon Survey, WAM 98/1656. Paratypes, same data as holotype but: 1♂, 27°00'21.6"S, 114°32'29.2"E, NE4, WAM 98 / 1657; 1♂, 11 May–18 Aug 1995, N. Hall, WAM 98 /1658.

Diagnosis. Males differs from those of P. jilbadji sp. nov. in the three (not four) pairs of spines on tibia I being weak, not strong. Female unknown.

Etymology. The species epithet is a noun in apposition from the type locality.
