Diagnosis

Males of A. vigilata sp. nov. can be distinguished from all species for which males are known except A. attenuata , A. blackdownensis , A. convoluta sp. nov., A. ferruginea sp. nov., A. giraulti , A. intermedia sp. nov., and A. pallida by a moderate to large body size (carapace length>4.0 mm), and the presence of a long embolus (embolus length / bulb length>1.5), a proximal excavation less than or equal to half the length of metatarsus I, and a prominent and sharp heel on metatarsus I ( Fig. 33Q View Fig ). Males of A. vigilata can be distinguished from those of A. ferruginea , A. giraulti , and A. pallida by the presence of an embolus that is not reflexed and does not have a small hook at the tip, and the presence of thorn-like setae along the retrolateral edge of the asetose depression on the palp tibia ( Fig. 33K–M View Fig ; cf. Figs 15 View Fig , 25 View Fig , 27 View Fig ). Males of A. vigilata can be distinguished from those of A. intermedia by the presence of a more gradually tapering embolus, with a narrower basal section ( Fig. 33L–M View Fig ; cf. Fig. 29 View Fig ). Males of A. vigilata can be distinguished from those of A. convoluta by the presence of a shorter embolus (embolus length/ bulb length <2) ( Fig. 33L View Fig ; cf. Fig. 23 View Fig ). Males of A. vigilata can be distinguished from those of A. attenuata by the presence of a copulatory organ with a more demarcated bulb and embolus ( Fig. 33L View Fig ; cf. Fig. 18 View Fig ). Males of A. vigilata can be distinguished from those of A. blackdownensis by the absence of erect, bristle-like setae on the posterior part of the abdomen ( Fig. 33B, D View Fig ; cf. Fig. 21 View Fig ).

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

Etymology

The specific epithet ‘ vigilata ’ is a Latin adjective meaning ‘vigilant’ or ‘watchful’, alluding to the use of Shoalwater Bay (where the species occurs) as a military training area.

Distribution and natural history

Aname vigilata sp. nov. occurs in central-eastern Queensland, at Shoalwater Bay, in the Central Mackay Coast bioregion ( Fig. 6 View Fig ). The form of burrows constructed by spiders of this species is unknown, but is likely to be similar to that of other pallida -complex species ( Fig. 6 View Fig ).
