Diagnosis

Females of Zephyrarchaea robinsi can be distinguished from Zephyrarchaea janineae and Zephyrarchaea mainae by the absence of dorsal hump-like tubercles on the abdomen (Fig. 13A); from Zephyrarchaea austini sp. n., Zephyrarchaea grayi sp. n., Zephyrarchaea marae sp. n. and Zephyrarchaea vichickmani sp. n. by the shallow post-ocular depression in lateral view (Fig. 9G); and from Zephyrarchaea barrettae sp. n. and Zephyrarchaea melindae sp. n. by the much shorter carapace (CH/CL ratio < 1.70) (Figs 7, 13A).
This species can also be distinguished from other genotyped taxa (see Fig. 3) by the following three unique nucleotide substitutions for COI and COII (n = 4): C(162), A(531), G(1442).

Description

Holotype female: Total length 3.69; leg I femur 1.97; F1/CL ratio 1.60. Cephalothorax reddish-brown; legs tan brown with darker annulations; abdomen variably beige-grey (Fig. 13A). Carapace short (CH/CL ratio 1.60); 1.23 long, 1.97 high, 1.13 wide; ‘neck’ 0.74 wide; highest point of pars cephalica (HPC) approaching posterior third of ‘head’ (ratio of HPC to post-ocular length 0.61), carapace with shallow concave depression anterior to HPC; ‘head’ not strongly elevated dorsally (post-ocular ratio 0.24) (Fig. 9G). Chelicerae without accessory setae on anterior face of paturon. Abdomen 2.10 long, 1.78 wide; spherical in lateral profile, without dorsal hump-like tubercles. Internal genitalia (Figs 13B–D) with cluster of ≤ 15 sausage-shaped spermathecae either side of gonopore, clusters widely separated along midline of genital plate.
Male: Unknown.

Distribution and habitat

Zephyrarchaea robinsi is known only from Ellen Peak, Bluff Knoll and the south face of Pyungoorup Peak, on the eastern massif of the Stirling Range National Park of southern Western Australia (east of Chester Pass) (Fig. 23). Specimens have been collected by beating and sifting sedges (Lepidosperma sp.) in montane heathland habitats and along mesic, shaded creek lines.

Conservation status

This species is a short-range endemic taxon (Harvey 2002b[1]), with a maximum total range of less than 10 km2, and all known populations in the eastern Stirling Range National Park potentially threatened by fire, dieback disease (affecting montane vegetation) and climate change.
