Diagnosis

Males of A. convoluta sp. nov. can be distinguished from all species for which males are known except A. attenuata , A. blackdownensis , A. ferruginea sp. nov., A. giraulti , 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. 23Q View Fig ). Males of A. convoluta can be distinguished from those of A. ferruginea , A. giraulti , and A. pallida by the presence of an embolus that is not reflexed and does not have a small hook at the tip, and the presence of thorn-like setae along the retrolateral edge of the asetose depression on the palp tibia ( Fig. 23K–M View Fig ; cf. Figs 15 View Fig , 25 View Fig , 27 View Fig ). Males of A. convoluta can be distinguished from those of A. attenuata , A. blackdownensis , and A. vigilata by the presence of a longer embolus (embolus length / bulb length>2) ( Fig. 23L View Fig ; cf. Figs 18 View Fig , 21 View Fig , 33 View Fig ). Males of A. convoluta can be distinguished from those of A. intermedia by the presence of a more gradually tapering embolus, with a narrower basal section ( Fig. 23L–M View Fig ; cf. Fig. 29 View Fig ).

Females of A. convoluta sp. nov. can be distinguished from all species for which females are known except A. attenuata , A. blackdownensis , and A. platensis 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. 24L View Fig ). Females of A. convoluta can be distinguished from those of A. attenuata , A. blackdownensis , and A. platensis by the presence of spermathecae with longer, cork-screw shaped medial vesicles (medial vesicle length/ genitalia width ~ 0.6; cf. <0.5) ( Fig. 24L View Fig ; cf. Figs 19–20 View Fig View Fig , 22 View Fig , 32 View Fig ).

Etymology

The specific epithet ‘ convoluta ’ is a Latin adjective meaning ‘coiled’ or ‘twisted’, in reference to the long, coiled medial receptacle of the female genitalia of this species.

Distribution and natural history

Aname convoluta sp. nov. occurs in south-eastern Queensland in the Brigalow Belt South bioregion. It occurs west of Eidsvold, near the Palmgrove and Isla Gorge National Parks, with its range between Taroom in the south and Roundstone in the north ( Fig. 6 View Fig ). 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 View Fig ).
