Aname pallida L. Koch, 1873 – Raven 1985: 403 (synonymy of Chenistonia giraulti Rainbow, 1914 with Aname pallida L. Koch, 1873 here rejected). — Harvey et al. 2018: fig. 16g (imaged female QMB S9413 from Mount Elliot, here identified as A. giraulti).
non Aname collinsorum – Raven 1985: figs 12, 31, 55, 57 (illustrated female allotype QMB S1260 [100 Mile Swamp, Rosella Plains], and two females QMB S1284 [Mount Mulligan], here identified as A. scutitheca sp. nov.).
Diagnosis
Males of A. giraulti 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. 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. 27Q). Males of A. giraulti 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. 27K–M; cf. Figs 18, 21, 23, 29, 33). Males of A. giraulti can be distinguished from those of A. ferruginea by the presence of a longer and more reflexed embolus (embolus length/bulb length>2.2), and a shorter, more triangular tibial spur (Fig. 27J–Q; cf. Fig. 25). Males of A. giraulti can be distinguished from those of A. pallida by the presence of a shorter embolus (embolus length / bulb length ~2.3; cf. ~ 2.5 in A. pallida) (Fig. 27L; cf. Fig. 15).
Females of A. giraulti can be distinguished from all species for which females are known except A. ferruginea sp. nov. 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. 28D, L). Females of A. giraulti can be distinguished from those of A. ferruginea by the presence of spermathecae with more elongate lateral vesicles (lateral vesicle length/ width>2) (Fig. 28L; cf. Fig. 26). Females of A. giraulti can be distinguished from those of A. pallida by their distribution (Fig. 6), occurring in tropical north Queensland, in the Wet Tropics, Einasleigh Uplands or the northern part of the Brigalow Belt North bioregions (based on current data females of A. pallida and A. giraulti cannot be confidently distinguished morphologically) (Fig. 28; cf. Fig. 16).

Distribution and natural history
Aname giraulti occurs in north-eastern Queensland, in the Brigalow Belt North, Einasleigh Uplands and Wet Tropics bioregions, extending from around Mount Elliot, in the south, to approximately Mount Molloy in the north, and as far west as Rosella Plains (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).
Remarks
This species was previously in synonymy with Aname pallida; however, morphological examination, along with molecular divergence values (12.22% average pairwise divergence for COI) indicate that it is a distinct species, of which Aname collinsorum Raven, 1985 is a junior synonym. Although we have examined both the A. giraulti lectotype and the A. collinsorum holotype to confirm that they are conspecific, we have imaged the A. collinsorum holotype due to it being more recently collected and in better condition.
