Diagnosis

Males of A. corundaria sp. nov. can be distinguished from all species for which males are known except A. callitra sp. nov. by a small body size (carapace length <4.0 mm), and the presence of a copulatory organ with a short embolus (embolus length/ bulb length <1.5) and an angular bulb with a slight ridge adjacent to the embolus ( Fig. 95J–Q View Fig ). Males of A. corundaria can be distinguished from those of A. callitra by the presence of a thinner, more strongly curved embolus ( Fig. 95L–M View Fig ; cf. Fig. 94 View Fig ).

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

Etymology

The specific epithet ‘ corundaria ’ is an adjective formed from the Latinised ‘ corundum ’, meaning the mineral corundum that forms sapphires and rubies, and the suffix ‘- aria ’ denoting a connection or association, in reference to the distribution of this species near the ‘Gemfields’ region of central Queensland, which is famous for its sapphire and ruby deposits.

Distribution and natural history

Aname corundaria sp. nov. occurs in central Queensland, in the Brigalow Belt North bioregion. It is known from three locations, near Sapphire, Drummond Range, and Alpha respectively ( Fig. 13 View Fig ). The form of burrows constructed by spiders of this species is unknown.
