Diagnosis

Males of A. warrego sp. nov. can be distinguished from all species for which males are known except A. aurensis sp. nov., A. briggsi sp. nov., A. eddieorum sp. nov., A. hughenden sp. nov., A. longitheca , A. mulgana sp. nov., and A. rupicola sp. nov. by a moderate to large body size (carapace length>4.0 mm), the presence of a long embolus (embolus length/ bulb length>1.5) that has a relatively wide basal section tapering into an attenuate, sinuous distal section after about 0.4 of length, and the absence of a prominent sharp heel on metatarsus I (as in the pallida -complex) ( Fig. 48L–M View Fig ). Males of A. warrego can be distinguished from those of A. aurensis , A. briggsi , A. hughenden , A. mulgana , and A. rupicola by the presence of a tibia I that stays about the same width from the proximal end to the base of the tibial spur when in lateral view ( Fig. 48P View Fig ; cf. Figs 34 View Fig , 36 View Fig , 41 View Fig , 44 View Fig , 46 View Fig ). Males of A. warrego can be distinguished from those of A. eddieorum and A. longitheca by the presence of a thinner palp tibia (palp tibia length / width> 3) ( Fig. 48J–K View Fig ; cf. Figs 39 View Fig , 42 View Fig ).

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

Etymology

The specific epithet ‘ warrego ’ is a noun in apposition, referencing the distribution of this species in the Warrego River catchment, in the Carnarvon Range.

Distribution and natural history

Aname warrego sp. nov. occurs in central Queensland, in the Brigalow Belt South bioregion. It is known from two locations in Upper Warrego, near Carnarvon National Park ( Fig. 7 View Fig ). The form of burrows constructed by spiders of this species is unknown, but is likely to be similar to that of other eddieorum - complex species ( Fig. 7 View Fig ).
