Mar. 1974, M.R. Gray; ♀, KS34796; ♀, KS34794, with 60 young; both data as for KS34795.

Other material. AUSTRALIA: VICTORIA ♀, KS73046, 10 km S of Forrest on Forrest–Apollo Bay Rd, Otway Ranges, 38°35'S 143°43'E, 31 Mar. 1978, M.R. Gray, in road bank—regrowth Stringybark forest above, in large sheet web, c. 35×15 cm curving up & out from bank retreat.

Diagnosis. CL 3.71–4.08. Separated from all other species by the pit-like epigynal fossa and centrad placement of the RTA.

Male (holotype). BL 7.71, CL 3.71, CW 2.47, CapW 1.53, EGW 1.03, LL 0.59, LW 0.50, SL 1.75, SW 1.49. Legs: 1423 (I 15.05, II 13.42, III 11.04, IV 13.89); ratio tibia I length:CW = 1:0.72. Male palp: Fig. 5a,b. Cymbium wide with well-developed retrolateral flange. Bulb longer than wide with tegular lobe placed basally. Embolus origin basal. Stem of T-shaped conductor anteriorly directed, posterior limb placed retrolaterally; tegular window small, prolateral. RTA large, centrad, and visible in ventral view; RVTA with broad, beak-like apex.

Female ( KS 34794). BL 7.67, CL 3.96 (3.96–4.08), CW 2.55, CapW 2.00, EGW 1.14, LL 0.63, LW 0.59, SL 1.82, SW 1.44. Standard colour pattern. Legs: 1423 (I 13.24, II 11.20, III 9.40, IV 11.60); ratio tibia I length:CW = 1:0.79. Epigynum: Fig. 5c,d View Figure 5 . Cordate, unpaired, central fossa with copulatory openings placed at anterolateral corners and opening posteromedially. Scape absent to rudimentary, probably represented by a midline cusp on the anterior epigynal margin. Internal genitalia: Fig. 5e View Figure 5 . Copulatory ducts short.

Distribution. Grampian and Otway Ranges, Victoria.

Comments. The Otway Range spiders may prove to be a separate species from the Grampian spiders but this will not be resolved until Otway males are available.

Etymology. The specific name refers to the pit-like epigynal fossa, unique within this genus.
