Male: Holotype : Cephalothorax long and very flat, mid to dark orange with scattered pennate grey hairs around the eyes and along the sides. Surrounds of ALE, PME and PLE, black with scattered grey hairs. Clypeus tiny, without a fringe of hairs ( Figs 1–2 ). Chelicerae mid to dark orange, straight, with fangs folded a little backwards towards a tapering inner surface ( Figs 3–4 ). Two, well separated, medium sized promarginal teeth and one medium sized, fissident, retromarginal tooth with two large terminal and a variable pattern of one or two small intermediate cusps ( Fig. 15 ). Endites and labium orange grading to yellow distally. Sternum orange. Abdomen long and narrow, dorsal surface yellow with a pair of longitudinal brown stripes (more recently collected males are not so faded and all show a pattern of brown and yellow bands grading to solid brown laterally down the sides of the abdomen (as in Fig. 8 ). Spinnerets small, yellow. Ventral abdomen light orange. Legs mid to dark orange. L1 more robust and larger than other legs, with grey fringe on tarsus and metatarsus. Strong spines on the patella, tibia and tarsus of L1; all other spines tiny or missing. Palp : light orange, with one short ( Figs 6–7 ) and one medium sized blunt tibial apophysis. Cymbium short, rounded. Tegulum rounded, without lobe. Embolus arises from a distinct mound on the prolateral distal edge of the tegulum and moves away from the tegulum before forming an anti-clockwise quarter circle. Dimensions: CL 3.90, EFL 1.55, CW 2.54, AEW 1.92, AMEW 1.24, PEW 2.17, AL 4.64, P1+T1 3.22, L1 7.49 (2.23+1.24+1.98+1.42+0.62), L2 4.02 (1.23+068+0.93+0.74+0.43), L3 4.27 (1.36+0.68+0.93+0.87+0.43), L4 6.01 (1.80+0.93+1.61+1.18+0.50). FIGURES 8–11. Pseudomaevia cognata , female (AM, KS122087). 8 dorsal view; 9 lateral view; 10 mouthparts, ventral view; 11 epigyne, ventral view. Scale: total body 2 mm; epigyne 0.2 mm. FIGURES 12–15. Pseudomaevia cognata , female (AM, KS22223). 12 epigyne, ventral view; 13 same, cleared, dorsal view; 14 same, transmission photograph; 15 two examples of variation in the retromarginal tooth. Scale: 0.2 mm. Female . As for the male, except animal much larger. Epigynum : median facing, ‘C-shaped’, guides and copulatory openings indistinct. Insemination ducts first move vertically a short distance (not apparent in figures). The ducts then move in a posterior direction with small lateral diverticula, and finally curve laterally and move forward again to end in the fertilization ducts ( Figs 11–14 ). There is no obvious shape differentiation of a spermatheca, however it may be that the vertical section is the insemination duct, the first two thirds of the horizontal section (orange coloured, Fig. 14 ) is the spermatheca and the final third the fertilization duct.

Distribution and biology. The species is known only from Lord Howe Island, an Australian administered island 700km north-east of Sydney in the Tasman Sea. It has been collected on foliage and in pitfall traps.
