A–B, Cephalothorax and abdomen, lateral view: A, allotype female (QMB S90186) from Tamborine National Park, Queensland; B, holotype male (QMB S90185) from Tamborine National Park, Queensland. C, Holotype male chelicerae, lateral view, showing accessory setae. D–F, Holotype male pedipalp: D–E, bulb, retrolateral view; F, detail of distal tegular sclerites, prodistal view. G, Allotype female internal genitalia, dorsal view. C = conductor; E = embolus; Es = embolic sclerite; T = tegulum; (TS)1–3 = tegular sclerites 1–3. Scale bars: A–B = 1.0 mm; E = 0.2 mm.
