Diagnosis

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

Females of A. boreovillosa sp. nov. can be distinguished from all species for which females are known except A. occivillosa sp. nov. and A. villosa by the presence of spermathecae with two vesicles, with relatively long, undulating lateral vesicle (lateral vesicle length/ genitalia width>0.25) and tightly undulating medial vesicles (Fig. 73L). Females of A. boreovillosa can be distinguished from those of A. occivillosa and A. villosa by the presence of spermathecae with less elongate lateral vesicles with wide, rounded crowns (lateral vesicle length/ width <2.5) (Fig. 73L; cf. Figs 75, 79–80).

Etymology

The specific epithet ‘ boreovillosa ’ combines the Latin adjective ‘ villosa ’, meaning ‘hairy’ or ‘shaggy’ (and is the species epithet of a closely related and previously described species), with the prefix ‘ boreo -’, meaning ‘northern’, in reference to this species’ close relatedness to Aname villosa, and its northern distribution relative to that species.

Distribution and natural history

Aname boreovillosa sp. nov. occurs on the Blackdown Tableland in central-eastern Queensland, in the Brigalow Belt South bioregion, located between Emerald and Rockhampton (Fig. 11). It constructs an open, silk-lined burrow with silk spilling out from the entrance, sometimes with a built-up mound of soil around the entrance. The burrow has a short, hidden ‘wishbone’ entrance, which, when excavated, is revealed to terminate in a distinctly thick, white sheath of silk (Fig. 11).
