Genus Aname L. Koch, 1873

Aname L. Koch 1873: 465 . Type species Aname pallida L. Koch, 1873 , by monotypy.

Dekana Hogg 1902: 138 (synonymised by Raven 1981: 328 and Main 1982b: 27). Type species Dekana diversicolor Hogg, 1902 , by original designation.

Proshermacha Simon 1908: 113 (synonymised with Chenistonia by Main 1982a: 113). Type species Proshermacha subarmata Simon, 1908 (junior synonym of Chenistonia teppperi Hogg, 1902 ), by subsequent designation of Rainbow (1911).

Sungenia Rainbow and Pulleine 1918: 162 (synonymised by Raven 1981: 328 and Main 1982b: 27). Type species Chenistonia (Dekana) atra Strand, 1913 , by monotypy.

Dolichosternum Rainbow and Pulleine 1918: 168 (synonymised by Raven 1981: 328). Type species Dolichosternum attenuatum Rainbow and Pulleine, 1918 (junior synonym of Ixamatus distinctus Rainbow, 1914 ), by monotypy.

Diagnosis. Species of Aname differ from all other nemesiids by the presence of a large mega-spur on the tibia of leg I generally in a mid-distal position (e.g. Fig. 15 ), the absence of spines on the pedal tarsi (e.g. Fig. 19 ), and the absence of cuspules on the pedal coxae (e.g. Fig. 12 ) (following Main 1982b, 1983, 1986; Raven 1981). The male pedipalpal bulb is spherical to pear-shaped, with the embolus originating from the bulb in a distal position (e.g. Figs 17–20 ); the shape of the embolus is usually long and slender, and slightly curved in profile (e.g. Figs 17–20 ).

Remarks. While we are confident that there are four distinct species represented in our samples, we found considerable difficulty in distinguishing these species from some previously named species. Differentiating our species from those for which males have been described was not difficult. Several species of Aname are currently known only from adult females and for which spermathecae have not been described or illustrated. These are: A. armigera Rainbow & Pulleine, 1918 (from south-western Australia), A. aurea Rainbow & Pulleine, 1918 (from New South Wales), A. coenosa Rainbow & Pulleine, 1918 (from South Australia), A. comosa Rainbow & Pulleine, 1918 (from South Australia), A. cuspidata ( Main, 1954) (from south-western Australia), A. fuscocincta Rainbow & Pulleine, 1918 (from south-western Australia), A. grandis Rainbow & Pulleine, 1918 (from South Australia), A. hirsuta Rainbow & Pulleine, 1918 (from South Australia), A. maculata ( Rainbow & Pulleine, 1918) (from south-western Australia), A. platypus ( L. Koch, 1875) (possibly from Australia), A. tasmanica Hogg, 1902 (from Tasmania) and A. villosa ( Rainbow & Pulleine, 1918) (from south-western Australia) ( Hogg 1902; Koch 1875; Main 1954; Rainbow & Pulleine 1918). As the type localities of all of these species are located at least 1,000 km away from the Pilbara region, we are confident that we have not inadvertently described a species that will eventually become a junior synonym.
