Adoxotoma embolica new species

( Figs 1–12 )

Type material. Holotype: male, Australia: Western Australia: Jarrahdale (Alcoa), Mine Area, 31°16'S, 116°06'E, April 1998, wet pitfall traps, K.E.C. Brennan ( WAMP T49411).

Etymology. Derived from elongate embolus, adjective.

Diagnosis. Distinctive by the following combination of characters: embolus elongate, sabre-like, arising prolaterally; tegulum with prolateral lobe, protuberance and with small prolateral spur; retrolateral tibial apophysis broad, spade-like and distally curved towards cymbium.

Description. Male (holotype, Figs 1–12 ): Eye field dark brown, eye surroundings black. Thorax brown; all with scattered scale-like light hairs and with longer brown bristles anteriorly. Abdomen with shiny, greyish-brown scutum, sides greyish. Clypeus narrow, brown, with three central brown bristles and with long, rather fine whitish hairs overhanging towards chelicerae. The latter orange-brown, with scattered fine, brown hairs, promargin with two single teeth and retromargin with one fissidentate tooth. Maxillae and labium orange-brown with paler chewing margins. Sternum orange with darker margin. Venter and spinnerets grey. Legs with orange and brown markings, darker proximally and on sides, first pair more robust and darker than others. Tibiae I and metatarsi I with five and two pairs of ventrolateral spines, respectively. Leg formula: I– IV–II=III.
