Austrammo monteithi , new species Figures 6, 7 , 9–18 ; Map 1

TYPES: Male holotype and female allotype taken in a pitfall trap in open forest at an elevation of 340 m on the summit of Mount Gayndah , 25 ° 36 ̍ S, 151 ° 32 ̍ E, Queensland (Dec. 18, 1998 – Jan. 27, 1999; G. Monteith, Gough), deposited in QMB (S49852) .

ETYMOLOGY: The specific name is a pa­ tronym in honor of Dr. Geoff Monteith of the Queensland Museum, collector of the types and many other important gnaphosoid specimens.

DIAGNOSIS: Males have a wider retrolateral tibial apophysis than do those of A. harveyi (fig. 16); females have distinctively plump, posteriorly widened spermathecae (fig. 18).

MALE: Total length 3.7. Carapace olive brown, darkest anteriorly; abdomen shiny olive gray; legs olive brown, tarsi lighter than other segments. Leg spination: femora: I p0­ 0­0; II d0­1­0; III, IV p0­0­0; tibiae III, IV p0­0­0, v0­0­1p; metatarsi III, IV p0­0­1, r0­ 0­1. Palpal tibia with cup­shaped distoventral invagination, retrolateral tibial apophysis wide, tip chisel­shaped (fig. 16); palpal cymbium with group of about four thick macrosetae at tip, embolus with curved tip (fig. 15).

FEMALE: Total length 6.0. Coloration as in male. Leg spination typical for genus. Epigynum relatively large, triangular, with widely separated, posteriorly situated openings (fig. 17); spermathecae bipartite, anterior portion plump, widest posteriorly (fig. 18).
