Cassis , NE NSW NPWS Survey . Diagnosis . Differs from all species except P. macleayensis by presence of undivided, spine-like distal conductor; from P. macleayensis by the reduced MA and narrowly divergent processes of bifurcate RTA. Epigynal fossa and sclerotized area in front of it larger than in P. macleayensis . Male ( holotype ). BL 6.61, CL 3.06 (2.41–3.59), CW 2.08, CapW 1.27, EGW 0.90, LL 0.49, LW 0.49, SL 1.51, SW 1.35. Legs: 1243 (I: 17.83; II: 14.17; III: 11.83; IV: 14.00); ratio tibia I length:CW = 1:0.46. Male Palp: ( Fig. 10a,b ). Bifurcate RTA with two large, digitiform processes, diverging at an angle of less than 45° or subparallel, ends rounded with tip upturned and pointed. RVTA with a low retroapical ridge. Tegular lobe basal. Embolic origin probasal. Conductor stalked, bent and extended retrolaterally as a sickle-like, grooved spine. MA reduced toa short, membraneous spine (or 2 smaller spines) with a fleshy, collar-like ridge at base; or MA indistinct. Fig. 9 . Pillarakaruah n.sp. ( a–f ) Spinnerets, female KS75399: ( a ) spinningfield (cribellum below), ( b ) cribellumandspiracle. ( c–f ) Spigots: ( c ) ALS, ( d ) PMS, ( e ) PLS, ( f ) detailof PLSapexwithmodified PLSspigot. (Spigot abbreviations, see Fig. 3). Female (KS70335). BL 6.49, CL 2.69 (2.04–2.73), CW 1.88, CapW 1.22, EGW 0.82, LL 0.41, LW 0.41, SL 1.29, SW 1.16. Legs: 1423 (I: 11.67; II: 9.42; III: 7.92; IV: 9.58); ratio tibia I length:CW = 1:0.63. Epigynum: (KS70337, Fig. 10c,d ). Fossa a subcircular pit, copulatory ducts opening from anterior end, cuticular area anteriorto fossalip strongly sclerotized. Internalgenitalia: (KS70337, Fig. 10e ). Copulatory ducts moderately broad; spermathecae touching medially. Variation . MA always reduced but varies from 1–2 membraneous “spines” to indistinct. The low, collar-like ridge around the MA base may be homologous with the fleshy part of the MA in Borrala spp. Distribution . Barringtonmassif region, New South Wales .
