Diagnosis
Males of A. intermedia 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. pallida, and A. vigilata sp. nov. 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. 29Q). Males of A. intermedia can be distinguished from those of A. attenuata, A. blackdownensis, A. convoluta, A. ferruginea, A. giraulti, A. pallida, and A. vigilata by the presence of a relatively wide basal section on the embolus, which then tapers to an attenuate, sinuous distal section after about 0.4 of length (similar to eddieorum -complex species) (Fig. 29L–M; cf. Figs 15, 18, 21, 23, 25, 27, 33).
Females of A. intermedia sp. nov. can be distinguished from all species for which females are known by the presence of spermathecae with relatively short and wide lateral vesicles (lateral vesicle length / width ~1) and large, banana-shaped medial vesicles curving from a medial to lateral angle (medial vesicle length /lateral vesicle length ~2.6) (Fig. 30L).
Etymology
The specific epithet ‘ intermedia ’ is a Latin adjective referencing the intermediate morphology of this species between species of the pallida - and eddieorum -complexes.

Distribution and natural history
Aname intermedia sp. nov. occurs in north-eastern Queensland, near the boundaries of the Einsleigh Uplands, Desert Uplands, and Brigalow Belt North bioregions. It is known from two general localities, one in western Townsville and the other just west of Charters Towers (Fig. 6). It constructs an open, silk-lined burrow without silk outside of the entrance, often on an angle, and with a hidden secondary ‘wishbone’ entrance (Fig. 6).
