Differs from other species in having the lesser spine on the spiniform sclerotized lateral process of MA reduced to a spicule (not “claw-like”); and the epigynal fossa without a dividing septum. Description Male ( holotype ). BL 8.80, CL 4.12 (range 3.22–4.16), CW 2.84, CapW 1.71, EGW 1.14, LL 0.68, LW 0.61, SL 1.95, SW 1.62. Legs: 1243 (I: 19.73; II: 16.33; III: 13.40; IV: 15.40); ratio tibia I length:CW = 1:0.56. Sternum dark brown. Male palp ( Fig. 12a,b ). RVTA large, anvil shaped (lateral view). Cymbium apex short coniform. Cymbial flange very wide. Bulb wider than long. Prolateral margin of TL rounded, sometimes with a small thorn-like protuberance. Lateral process of MA slender spiniform, with secondary spine reduced to a spicule ( Fig. 12b ). Female (KS77020) BL 8.41, CL 3.80 (range 3.80–4.29), CW 2.65, CapW 1.80, EGW 1.16, LL 0.65, LW 0.65, SL 1.88, SW 1.57. Legs: 1243 (I: 14.83; II: 12.67; III: 10.67; IV: 12.33); ratio tibia I length:CW = 1:0.71 Sternum dark brown. Epigynum ( Fig. 12c–e ). Fossa open, without median septum or posterior knob, longer than wide, narrowest anteriorly. Internal genitalia (KS46081) with short copulatory ducts and large spermathecae separated by about a third of spermatheca width. Comments . All other Jamberoo species have a divided epigynal fossa. Possession of an open fossa initially precluded placing the Mt Buller–Mirimbah males and females together. However, collecting has not revealed a second “striped” species in this region so that the male– female matching seems reliable. The midline area of the fossa rises ventrally from front to back, possibly reflecting a former or incipient division of the fossa. Distribution . Southern Great Dividing Range, eastern Victoria . Etymology . The name refers to the southern distribution of this species.
