Diagnosis. In male: Medium sized brown spider, carapace length c. 6–7.5, retrodorsal surface of metatarsus IV with at least one spine ( Fig. 7F View Fig ); venter pale with dark brown maculations forming pattern, most concentrated in median band ( Fig. 7H View Fig ). Spines absent on tarsi I and II; tarsi IV with bilateral rows spines adjacent to weak scopula ( Fig. 7E,F View Fig ). Palpal bulb ( Fig. 7B,C View Fig ) retrolateral embolic flange with c. 7–9 distinct folds; embolus with blunt dorsal apophysis placed c. midway between embolic flange and embolus tip; tip from d aspect sinuous, flattened vertically. DTA small, hooked; conformation of palpal tibia as figured ( Fig. 7A View Fig ). Female not known.

Description

Male holotype ( Fig. 7A–H View Fig ). Size. Carapace length 7.49, width 6.69. Abdomen length 7.55, width 5.03. — Colour. In alcohol carapace, limbs and chelicerae brown. Some disconnected darker brown smudges on tibia and patella lateral surfaces of legs I and II. Carapace almost bare of golden hairs, more prominent on proximal limb segments. Abdomen dorsum discoloured. Venter pallid, with dark brown maculations most concentrated in median band ( Fig. 7H View Fig ). — Carapace. Edge fringed with black bristles which encroach onto posterior half of post foveal surface; few scattered interstrial bristles. Evidence of row of c. 7 black bristles on caput arch (some removed); 4 between PME; 8 on clypeus. Weakly chitonized area on pleuron membrane below clypeus with 4 bristles. Fovea width 1.38, straight, recurved edges, posterior wall lacking pitted intrusion. — Eyes. Raised on a mound. Ocular area adjacent to eyes black. Anterior width 1.25, posterior width 1.20, length 0.76, width/length ratio 1.64. Line joining posterior edges of ALE   transects anterior quarter of AME. Posterior row straight in front, recurved behind. — Chelicerae. Rastellum front row of 6(7) spines, 3(4) smaller spines behind, few receding along pl edge. Fang groove and intercheliceral tumescence obscured. — Labium. Bulbous, length 0.83, width 1.15. Labiosternal suture broad, continuous, narrow midway. — Maxillae c. 15(14) elongate, pointed antero-ental cuspules, all surmounted by a hair. — Sternum. Broad, bulbous, length 4.35, width 3.75. Sigilla first and second pairs small, round, submarginal; third pair much larger, distant from margin. — Legs. Tibia I with distal bifid apophysis; distal process with 3(2) squat, blunt, compact spines; proximal process with row of 2(2) longer, curved, blunt spines.

Anterior face with cover of long, erect, dark brown bristles. All setae and colour lost on pallid dorsum. Venter ( Fig. 7H View Fig ) covered with weak short erect brown bristles.

Etymology. The species is named in recognition of Louise Kampen, technical officer, Australian Museum, Sydney.

Distribution and natural history ( Fig. 14A View Fig ) This species is known from Benandarah State Forest (type locality) near Batemans Bay, New South Wales ( Australia), north to Kioloa State Forest (35°37'S 150°16'E) near Kioloa, NSW and south to Bodalla State Forest (36°16'55"S 149°53'31"E) near Bodalla, NSW, localities occupying a linear distance of about 80 km along the coast. The burrow is not known. Limited information indicates mature males wander during the annual period of March to September.
