Holotype male: Great Otway National Park , Maits Rest , 10 km W. of Apollo Bay , Victoria , Australia , sifting moss from trunk of Nothofagus cunninghamii , 38°45'19"S , 143°33'18"E , 23.IV.2006 , M. Rix ( NMV K10768 ). Paratypes : Allotype female, same data as holotype ( NMV K10769 ); 1 male , same data as holotype ( WAM T94443) . Etymology . The specific epithet is derived from the Latin ‘ocellatus’, meaning ‘having little eyes’ ( Brown 1956 ), and refers to the small eyes of this species. Diagnosis . Males of Eterosonycha ocellata can be distinguished from all other described congeners by the shape of the distal conductor, which has a tubular prolateral process and bifurcate retrolateral process ( Fig. 55 ). Females can be distinguished from all other described congeners by the distinctive shape of the external epigyne ( Fig. 54D ). Both sexes can also be recognised by the relatively small eyes ( Fig. 54C ). Description . Holotype male : Total length 0.83. Carapace 0.42 long, 0.35 wide. Abdomen 0.57 long, 0.41 wide. Leg I femur 0.33. Body colour pale tan-yellow, carapace slightly darker. Carapace raised anteriorly, not fused to sternum except around petiole; dorsal surface of pars cephalica slightly convex in lateral view. Eight eyes present on anterior margin of pars cephalica; AME 0.5x diameter of ALE; PME separated by slightly more than their own diameter. Chelicerae each with large, bulging anterior projection; promargin with three peg teeth. Legs relatively short (leg I femur-carapace ratio 0.79); distal, prolateral macroseta present on tibia I. Abdomen oval, covered with hair-like setae; dorsal scute large, covering most of dorsal surface of abdomen; lateral sclerotic strips absent. Pedipalpal patella with retrolaterally-directed, hooked lRPA and expanded distal region with ornate, ridged cuticular microstructure; tibia enlarged, with pronounced, curved posterior process; tegulum large, bulging posteriorly, with excavate ETR and large, divergent, fleshy distal conductor bearing tubular prolateral process and bifurcate retrolateral process; embolus short (length <5× width), spur-like, situated adjacent to base of conductor ( Fig. 55 ). Allotype female : Total length 1.00. Carapace 0.47 long, 0.33 wide. Abdomen 0.62 long, 0.46 wide. Leg I femur 0.35. Cephalothorax, abdominal sclerites, legs tan-yellow; abdomen dark olive brown dorsally, with chequered dark-olive and tanyellow pattern laterally and ventrally. Carapace raised anteriorly, not fused to sternum except around petiole; dorsal surface of pars cephalica slightly convex in lateral view. Eight eyes present on anterior margin of pars cephalica; AME 0.5x diameter of ALE; PME separated by their own diameter. Chelicerae without bulging anterior projections; promargin without peg teeth. Legs relatively short (leg I femurcarapace ratio 0.74); macrosetae absent. Abdomen oval, covered with hair-like setae; dorsal scute and lateral sclerotic strips absent. Pedipalp entire, five-segmented. Epigyne heavily sclerotised externally, with distinctive morphology ( Fig. 54D ); spermathecae looped and twisted; insemination ducts broad, curved; fertilisation ducts filiform (Fig. 51D). Distribution . Known only from the Otway Ranges of Victoria . Remarks . Eterosonycha ocellata is an unusual species of Eterosonycha , currently known only from the Otway Ranges of Victoria . The type specimens were found living together in moss on the trunk of a large Southern Beech ( Nothofagus cunninghamii ) tree, in dark, wet, cool-temperate rainforest at Maits Rest.
