Pseudolampona marun , new species Figures 762–765 ; Map 86

TYPE: Male holotype taken in Berlese sample of closed forest litter at Marun , Prince Frederick Harbour , 158009S, 1258219E, Western Australia (June 6–11, 1988; I. Naumann), deposited in QMB .

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

DIAGNOSIS: Males and females have not been taken together, and are from distant localities, but are matched here until addition specimens indicate that more than one species of this genus inhabits the northern half of Western Australia. Males can be recognized by the relatively narrow embolus and short retrolateral tibial apophysis (figs. 762, 763), females by the almost circular epigynal margins (fig. 764).

MALE: Total length 2.3. Abdominal dorsum with four dark chevrons, venter unmarked. Retrolateral tibial apophysis very short, triangular (fig. 763); embolus relatively narrow, especially in distal half (fig. 762).

FEMALE: Total length 3.5. Coloration as in male. Lateral epigynal margins anchored by lateral pockets at about half of epigynal length, forming almost circular rim (fig. 764), spermathecae with short posterior lobes (fig. 765).

OTHER MATERIAL EXAMINED: Western Australia: cave C.15, Cape Range , 228139S, 1138599E, June 28, 1989 (M. Harvey, WAM 96 /738), 1 /; site TL­5, NW Cape Peninsula, 228069S, 1148009E, June 3, 1990, litter (J. Waldock, WAM 96 /739), 1 /.

DISTRIBUTION: Known only from the northern half of Western Australia (map 86).
