Aname pallida L. Koch, 1873 – Raven 1981: figs 8–10, 14, 44–47, 49 (illustrated male QMB S696 [Rockhampton], females QMB S697 [Biloela], QMB S703 [Monto], and females from fig. 46 [Gin Gin], fig. 47 [Banana], fig. 49 [Gladstone], here identified as A. ferruginea sp. nov.).

Diagnosis

Males of A. ferruginea sp. nov. can be distinguished from all species for which males are known except A. attenuata, A. blackdownensis, A. convoluta sp. nov., A. giraulti, A. intermedia sp. nov., 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. 25Q). Males of A. ferruginea can be distinguished from those of A. attenuata, A. blackdownensis, A. convoluta, A. intermedia, and A. vigilata by the presence of a reflexed embolus with a small hook at the tip, and the absence of short, thorn-like setae along the retrolateral edge of the asetose depression on the palp tibia (Fig. 25K–M; cf. Figs 18, 21, 23, 29, 33). Males of A. ferruginea can be distinguished from those of A. giraulti and A. pallida by the presence of a shorter and less reflexed embolus (embolus length /bulb length ~ 2), and a longer, more digitiform tibial spur (Fig. 25J–Q; cf. Figs 15, 27).

Females of A. ferruginea sp. nov. can be distinguished from all species for which females are known except A. giraulti and A. pallida by the presence of spermathecae with two vesicles, with relatively long and straight lateral vesicles (lateral vesicle length /genitalia width>0.25) that curve medially at their ends, and very short, straight medial vesicles (medial vesicle length/ lateral vesicle length <0.5) (Fig. 26D, L). Females of A. ferruginea can be distinguished from those of A. giraulti and A. pallida by the presence of spermathecae with shorter, wider lateral vesicles (lateral vesicle length /width <1.5) (Fig. 26L; cf. Figs 16, 28).

Etymology

The specific epithet ‘ ferruginea ’ is a Latin adjective meaning ‘rusty’, or ‘of the colour of iron-rust’, in reference to the general dark red-brown hue of the spider and the reflective bronze setae on its carapace.

Distribution and natural history

Aname ferruginea sp. nov. occurs in central-eastern Queensland, in the Southeast Queensland, Brigalow Belt South and Brigalow Belt North bioregions, extending from around Bundaberg in the south to Sarina in the north, and west to around Banana (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).
