Austrarchaea clyneae is a species of spider in the family Archaeidae. It is endemic to Australia.

Holotype male: Total length 2.87; leg I femur 2.72; F1/CL ratio 2.62. Cephalothorax reddish-brown; legs tan-brown with darker annulations; abdomen mottled grey-brown and dark beige, with darker reddish-brown dorsal scute and sclerites (Fig. 13A). Carapace very tall (CH/CL ratio 2.22); 1.04 long, 2.31 high, 0.99 wide; ‘neck’ 0.51 wide; bearing two pairs of rudimentary horns; highest point of pars cephalica (HPC) near posterior third of ‘head’ (ratio of HPC to post-ocular length 0.63), carapace with concave depression posterior to HPC; ‘head’ not strongly elevated dorsally (post-ocular ratio 0.23) (Fig. 8F). Chelicerae with short brush of accessory setae on anterior face of paturon (Fig. 13B). Abdomen 1.54 long, 1.18 wide; with three pairs of dorsal hump-like tubercles (HT 1–6); dorsal scute fused anteriorly to epigastric sclerites, extending posteriorly to first pair of hump-like tubercles; HT 3–6 each covered by separate dorsal sclerites. Unexpanded pedipalp (Figs 13C-E) with thin, gently-curved, pointed conductor; tegular sclerite 1 (TS 1) very long, spiniform, reaching to near distal tip of conductor, visible in retrolateral view; TS 2 spur-like, shorter than TS 1; TS 2a sinuous, largely obscured by TS 2; TS 3 indistinct, embedded within distal haematodocha, barely visible beyond retro-distal rim of tegulum. Female: Unknown.

Austrarchaea clyneae is known only from rainforest habitats in the Mount Clunie National Park of extreme north-eastern New South Wales (Fig. 31). A juvenile specimen from Tooloom National Park (near Urbenville) may also belong to this species based on proximity.
