Male ( Fig. 1A). Cephalothorax pear-shaped, covered with rather numerous white adpressed hairs—especially on sides and with scattered brown bristles. Eye field contrasting orange, AME area dark-brown, other eyes surrounded with black. Thorax orange-brown anteriorly with radial darker markings and darkening towards lower margins. Abdomen dark-grey with light pattern made of guanine crystals. Hairs few, white—especially on sides, and brown. Spinnerets rather long, smudged light-brown. Clypeus narrow

, dark-

orange with some brown bristles. Chelicerae long, dark- brown with orange apices, and with 2 promarginal and 5 retromarginal teeth (Fig. 1D). Pedipalps yellow.

Femora I black-brown on sides, distally slightly lighter, dorsally and ventrally light-brown. Patellae I with dark sides, distally and dorsoventrally yellow, tibiae similar in colour, with 5–6 prolateral and 5 retrolateral

spines. Metatarsi I with 2 pairs of long spines, yellow proximally and distally, the rest brown. Tarsi I yellow. Other legs more delicate and generally lighter, with dark patches on sides of femora, patellae and tibiae. Legs I densely covered with brown hairs, especially on tibiae and metatarsi. Following legs less clothed, hairs lighter. Palpal organ (Fig. 1B,C) elongated, with ribbon-like, long embolus and distinctive ventral apophysis.

Distribution ( Fig. 2). Known only from Mullion State Forest (NSW).

Remarks. Only three species of Arasia   are known: A. mollicoma (Koch)   , A. eucalypti Gardzińska   and the present species, all of them are tree-trunk dwellers in open sclerophyll forests. Arasia aurea (Koch)   listed by Wanless (1988) is excluded from Adoxotoma   and transferred to the genus Sondra   (see below).
