Diagnosis

Males of A. viridiensis sp. nov. can be distinguished from all species for which males are known by the presence of thorn-like setae along the retrolateral edge of the asetose depression on the palp tibia, becoming denser proximally, and a copulatory organ with the bulb tapering gradually into the relatively long embolus (embolus length / bulb length ~2) with distinct curve at about 0.6 of length, and a small hook at the tip of the embolus ( Fig. 120J–P View Fig ).

Females of A. viridiensis sp. nov. are unknown.

Etymology

The specific epithet ‘ viridiensis ’ is a Latin adjective combining the Latin ‘viridis’ meaning ‘green’ or ‘verdant’, and the suffix ‘- ensis ’ indicating connection to a place, referencing the type locality of this species in the lush tropical forest of the McIlwraith Range in Cape York.

Distribution and natural history

Aname viridiensis sp. nov. occurs in far northern Queensland, in the Cape York Peninsula bioregion, in the McIlwraith Range near Coen ( Fig. 14 View Fig ). The form of burrows constructed by spiders of this species is unknown.
