Opisthoncus abnormis: Koch L. 1881: 1221   ; Peckham & Peckham 1889: 28; Simon 1903: 828, 829; Rainbow 1911: 308; Żabka 1991: 44; Richardson & Żabka 2003.

Type material. Australia: Sydney (NSW), 3 F syntypes, ZMH, Mus. Godeffroy 7738.

Remarks. Koch and Keyserling (1881) described both sexes from Peak Downs and Sydney. The remaining material comprises 3 females, most likely syntypes from Sydney.

Diagnosis. In comparison with close O. keyserlingi   colour pattern different, insemination duct course and spermathecae position parallel (vs. V-shaped) and proximal loop of insemination duct much smaller.

Description. Female ( Fig. 3 View FIGURE 3 ) about 6 mm long. Cephalothorax moderately narrow and high, almost rectangular (CW = 78 % of CL, CH = 53 % of CL), pale brown, eye field paler than thoracic part, eye surrounding black ( Figs 3 View FIGURE 3 B, D). Whole area sparsely covered with short, recumbent pallid scales. Clypeus moderately wide, pale brown, with whitish scales and hairs below AME ( Fig. 3 View FIGURE 3 C). Cheliceral retromargin with with 2 -cuspidate fissident tooth ( Fig. 3 View FIGURE 3 E). Chelicerae pale brown, retromargin with two-cuspidate fissident tooth, endites and labium of the same colour, but with yellow anterior margins. Sternum relatively narrow, yellow, with scattered fine, brownish hairs ( Fig. 3 View FIGURE 3 F). Abdomen with longitudinal serrate pallid streak, bordered by dark areas. Venter yellowish, somewhat darker on sides, spinnerets yellow. Legs yellow with orange tibiae, metatarsi and tarsi. Pedipalps yellow with orange tarsi. Epigyne ( Figs 3 View FIGURE 3 I –J) with triangular posterior notch, copulatory openings located anteriorly, insemination ducts with proximal loop, further straight, slightly widening, spermathecae beanshaped. Accessory glands at the entrance of insemination ducts.

Dimensions. CL 2.20 (2.08–2.20), CW 1.72 (1.60–1.72), CH 1.16 (1.08–1.16), AEW 1.60 (1.48–1.60), PEW 1.60 (1.48–1.60), EFL 0.80 (0.72–0.80), AL 3.28 (2.68–3.28), AW 1.80 (1.56–1.80), L 1 4.36 (1.20 + 0.96 +1.00+ 0.76 + 0.44).
