Diagnosis

Males of A. braemar sp. nov. are unknown.

The single female holotype (probably subadult) of A. braemar sp. nov. can be distinguished from all species for which females are known except A. barakula sp. nov., A. lambkinae sp. nov., and A. truncata 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 medial vesicles with few bends (usually one or two), and a narrow sternum (sternum length / width>1.3) (Fig. A–L). This subadult female of A. braemar can be distinguished from those of A. lambkinae and A. truncata by the presence of (likely rudimentary) spermathecae with lateral vesicles with a wide base and distinct, slightly wider crowns ( Fig. 52L View Fig ; cf. Figs 54–55 View Fig View Fig ), and from those of A. barakula by the presence of spermathecae with longer medial vesicles (medial vesicle length / lateral vesicle length ~1.2; cf. ~ 0.8 in A. barakula ) ( Fig. 52L View Fig ; cf. Fig. 51 View Fig ).

Etymology

The specific epithet ‘ braemar ’ is a noun in apposition, referencing the distribution of this species within and around Braemar State Forest in south-eastern Queensland.

Distribution and natural history

Aname braemar sp. nov. occurs in south-eastern Queensland, in the Brigalow Belt South bioregion, in and around Braemar State Forest, near the town of Dalby ( Fig. 8 View Fig ). It constructs an open, silk-lined burrow with silk spilling out from the entrance, and sometimes with a slightly built up ‘collar’ of soil around the entrance, and with a hidden secondary ‘wishbone’ entrance ( Fig. 8 View Fig ).

Remarks

The holotype of A. braemar sp. nov. is probably subadult. However, because the spermathecae are relatively well formed and distinct, and morphological and molecular data both indicate that A. braemar is a distinct species, and in the interests of comprehensively documenting the genus in the region, we have chosen to describe A. braemar here despite the morphologically suboptimal holotype specimen.
