  • S.o. male(1) (holotype): Canterbury Museum, Christchurch; #885[1]
  • S.o. female(1) (allotype): Canterbury Museum, Christchurch; #886[1]
  • S.o. female(1) (paratype): Canterbury Museum, Christchurch; #887[1]
  • S.o. male(2) + female(3): Canterbury Museum, Christchurch; #922 & Dominion Museum, Wellington; #2/923[1]

DiagnosisEdit

(from Forster, 1954[1])

  • Color: Ground color yellow-brown, with black shaded pattern on the dorsal surface of the scute. Chelicerae and pedipalps with black reticulate markings. Legs with alternate black and pale-brown bands.
  • Body: The eyes are separated from the anterior margin of the carapace by a distance which is equal to ¼ of the total length of the scute, and are separated from each other by a distance slightly less than 5x their diameter. The surface of the scute is finely and evenly granulate. Areas 1-5 are separated by shallow grooves visible on the median surface. Free tergites and the sternite are smooth. The proximal half of the genital operculum is sub-triangular but distal half narrow, terminated bluntly, without lateral lobes (Fig. 712).
  • Genitalia: Aedeagus long and slender, tubular, without lateral processes. Dorsal plates present, spiniform. Ventral plate present as a short and concave plate, with 3 setae on each lateral margin (Fig. 711).
  • Chelicerae: Disto-dorsal surface of the second segment distended. Second segment with low tubercles on the dorsal surface.
  • Pedipalps: (Fig. 708) There is a small sub-conical mound on the disto-ventral surface of the trochanter and the proximo-dorsal surface of the femur and a further similar low mound on the disto-dorsal surface of the trochanter and a few small granules on the pro-lateral surface as shown in Fig. 709. The disto-dorsal process of the tibia is well-developed and digitiform. Tarsus slender, slightly sinuous, disto-ventral spine short, equal to ½ the length of the tarsal claw.
  • Legs: Smooth. Tarsal formula 3.5.4.4. The tarsal claws of legs 3 and 4 are as shown in Fig. 713; the arolium extends well beyond the median branch, anterior portion with median incision.
  • Measurements (mm): Scute: 1.68x1.40; Legs: 4.38, 6.12, 4.88, 6.09; Pedipalp: 4.02; Chelicera: 1.01
  • Female: Genital operculum almost 2x as wide as it is long. Pedipalps as shown in Fig. 710, tarsus relatively shorter than male and stout.
  • Measurements (mm): Scute: 1.56x1.50; Legs: 4.13, 5.78, 4.85, 5.96; Pedipalp: 3.96; Chelicera: 0.96
