Aname barrema Raven, 1985 – Raven 1985: fig. 72 (illustrated female paratype QMB S1243 [Girraween National Park] assigned to A. barrema Raven, 1985, here identified as A. platensis sp. nov.).
Diagnosis
Males of A. platensis sp. nov. can be distinguished from all species for which males are known by a moderate to large body size (carapace length>4.0 mm), the presence of a long embolus (embolus length / bulb length>1.5), a narrow sternum (sternum length / width>1.3), and a thick metatarsus I with a rounded heel (metatarsus I length /width ~3.5) (Fig. 31A–Q).
Females of A. platensis sp. nov. can be distinguished from all species for which females are known except A. attenuata, A. blackdownensis, and A. convoluta sp. nov. by the presence of spermathecae with two vesicles, with relatively long and straight lateral vesicles (lateral vesicle length/ genitalia width>0.25), and long medial vesicles (medial vesicle length/ lateral vesicle length>1) that project at an antero-medial angle (Fig. 32L). Females of A. platensis can be distinguished from those of A. convoluta by the presence of spermathecae with less elongate medial vesicles (medial vesicle length / genitalia width <0.5) (Fig. 32L; cf. Fig. 24). Females of A. platensis can be distinguished from those of A. blackdownensis by the absence of bristle-like setae covering the posterior part of the abdomen (Fig. 32B, D; cf. Fig. 22). Females of A. platensis can be distinguished from those of A. attenuata by the presence of spermathecae with thicker, straighter medial vesicles (medial vesicle length / width ~ 3.3; cf. ~ 4.1 in A. attenuata) (Fig. 32L; cf. Figs 19–20).
Etymology
The specific epithet ‘ platensis ’ is an adjective formed from the Latin ‘ platus ’ signifying a flat or broad surface, and the suffix ‘- ensis ’, which signifies a connection to a location, in reference to the distribution of this species in the highlands or ‘plateau’ around Stanthorpe, Queensland, which represents the northern extent of the New England Tableland bioregion.

Distribution and natural history
Aname platensis sp. nov. occurs in south-eastern Queensland (and potentially north-eastern New South Wales), in the New England Tablelands and Nandewar bioregions, extending from around Liston in the north to the Girraween National Park in the south (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).
