Diagnosis. Separated from J. boydensisand J. australisby the distally “claw-like” appearance of the large sclerotized lateral process of MA; and from J. australisby the presence of an epigynal septum. Differs from the closely related J. actensisby the digitiform shape of the distal cymbium, relatively longer prolateral conductor limb and epigynal fossae narrowest anteriorly.
Description Male( holotype). BL 7.50, CL 4.17 (range 2.65–4.24), CW 3.08, CapW 1.80, EGW 1.18, LL 0.68, LW 0.68, SL 2.08, SW 1.63. Legs 1243, long (I: 27.00; II: 22.50; III: 16.92; IV: 20.33); ratio tibia I length:CW = 1:0.43. Male palp ( Fig. 9a,b). Cymbium apex short digitiform. Bulb subcircular, about as wide as long. Conductor with a short to very short prolateral limb, about a third length of retrolateral limb. TW of moderate size, prolateral. TL basal, prolateral margin rounded to bluntly coniform. Sclerotized lateral MA process large with a strong spiniform “claw”—the curved, terminal spine wide basally and inner surface concave ( Fig. 2i) Female(KS84010). BL 7.92, CL 3.02 (range 2.81–4.73), CW 2.08, CapW 1.39, EGW 0.94, LL 0.51, LW 0.51, SL 1.43, SW 1.31. Legs: 1423 (I: 12.78; II: 10.20; III: 8.90; IV: Gray & Smith: Stiphidiid spiders with grate-shaped tapeta 29 10.49); ratio tibia I length:CW = 1:0.65. Epigynum ( Fig. 9c–g). Fossae narrowest anteriorly. Median septum short, tapering posteriorly before expanding abruptly into a ventral sclerotized knob-like protuberance—note that the latter may vary in shape from the usual rounded to ovoid knob to a thin, keel-like lamina—that is usually placed clearly anterior to the epigastric groove. Internal genitalia with short, curved copulatory ducts and relatively small spermathecae, well separated.
Distribution. Southern and central coast and highlands of New South Wales.
Etymology. The species is named in honour of Mr John S. Noble OM, engineer, conservationist, spider collector and photographer, and a long-time friend of the museum’s Arachnology Section. Jamberoo boydensis n.sp. Figs 8a, 10a–f
Type material. New South Wales: HOLOTYPE: ?, KS76979, Boyd Plateau, 34°00'S 150°03'E, M.R. Gray, in logs. PARATYPES: !, KS34761, Mt Edwards, Boyd Plateau, 33°50'S 150°00'E, 26 Nov. 1974, M.R. Gray, in log; !, KS34759, data as holotype; !, KS34762, Boyd Rivercrossing, Boyd Plateau, 34°03'S 150°05'E, M.R.

Diagnosis. Differs from other species by the elongate palpal prolateral conductor limb and the relatively long, slender epigynal septum with a small, rounded posterior knob..
Description Male( holotype). BL 6.86, CL 3.35, CW 2.45, CapW 1.31, EGW 0.94, LL 0.45, LW 0.49, SL 1.57, SW 1.37. Legs: 1423 (I: 14.82; II: 12.45; III: 10.41; IV: 12.65); ratio tibia I length:CW = 1:0.66. Male palp ( Fig. 10a,b). RVTA with dorsal process prominent. Cymbium apex short digitiform. Bulb ovoid, wider than long. Prolateral conductor limb elongated, much longer than retrolateral limb. TW prolateral to basal and very large. TL retrobasal with prolateral margin rounded. Sclerotized lateral process of MA with small “claw-like” bifurcation apically (much smaller than in J. johnnobleiand J. actensis). Female(KS34761). BL 6.29, CL 2.82 (range 2.73–3.31), CW 1.88, CapW 1.18, EGW 0.88, LL 0.41, LW 0.47, SL 1.39, SW 1.21. Legs: 1423 (I: 10.49; II: 8.61; III: 7.59; IV: 9.06); ratio tibia I length:CW = 1:0.72. Epigynum ( Fig. 10c–f). Median septum long and slender, with a small, rounded knob placed posteriorly near the epigastric groove. Internal genitalia with copulatory ducts looping dorsolaterally to enter the spermathecae posteriorly; spermathecae large, well separated.
Distribution. Known only from the typelocality.
Etymology. The name is taken from the typelocality.
