Aname truncata Wilson, Harvey, Simmons & Rix, 2025, sp. nov.

Aname truncata sp. nov. urn:lsid:zoobank.org:act: D2026664-38CE-4036-9196-8F93B8300690 Figs 1, 8, 55 Diagnosis Males of A. truncata sp. nov. are unknown. Females of A. truncata sp. nov. can be distinguished from all species for which females are known except A. barakula sp. nov., A. braemar sp. nov., and A. lambkinae 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. 55A–L). Females of A. truncata can be distinguished from those of A. barakula and A. braemar by the presence of spermathecae with lateral vesicles without distinct, widened crowns (Fig. 55L; cf. Figs 51). Females of A. truncata can be distinguished from those of A. lambkinae by the presence of spermathecae with less elongate lateral vesicles (lateral vesicle length/ width ~1.6; cf. ~ 3.6 in A. lambkinae) and straighter medial vesicles without distinct crowns (Fig. 55L; cf. Fig. 54). Etymology The specific epithet ‘ truncata ’ is a Latin adjective meaning ‘truncated’ or ‘cut-off’, in reference to the wide, truncate abdomen of this species relative to others.

Distribution and natural history Aname truncata sp. nov. occurs in central Queensland, in the Brigalow Belt South bioregion. It is known from two locations, both located in or near Palmgrove and Isla Gorge National Parks (Fig. 8). It constructs an open, silk-lined burrow with silk spilling out from the entrance, usually with a slightly built up ‘collar’ of soil around the entrance, and with a hidden secondary ‘wishbone’ entrance (Fig. 8).
