Type material examined. Syntype, 1♂, ZMB 20726, Wooroloo , Western Australia, Australia .

Other material examined. Queensland: ZMB 48561, 1♂, Yandina, 26°33'S 152°57'E, D. Harms, 9 July 2006 .

Diagnosis. Males of S. palliolata resemble those of S. arenata sp nov. by their striped legs, set of modified tibial and metatarsal macrosetae on leg I (long and thin barbs) ( Fig. 40A ), and palpi with a hyaline Pcym, single-tipped RTA and a flattened embolus resting on a tegular ridge retro laterally positioned ( Fig. 40C ). However, males of S. palliolata can be easily distinguished from those of S. arenata sp. nov. by longer and needle-shaped setae covering their entire body and, cymbium rounded but not retro-ventrally tilted ( Fig. 40C,D ).

Description. Male (ZMB 20726): Anterior eye row recurved and posterior straight, prosoma dark-yellow with a central and a pair of lateral brown patches ( Fig. 40A ). Leg I entirely reddish-brown and legs II, III and IV yellow with brown annuli along all segments ( Fig. 40A ). Opisthosoma obovate, with straight anterior border and covered by many needleshaped setae ( Fig. 40B ).
