Diagnosis

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

Females of A. dingo sp. nov. can be distinguished from all species for which females are known except A. aurensis sp. nov., A. briggsi sp. nov., A. camara, A. eddieorum sp. nov., A. longitheca, A. mulgana sp. nov., and A. rupicola 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 medially or posteromedially, before undulating anteriorly (Fig. 38L). Females of A. dingo can be distinguished from those of A. eddieorum and A. mulgana by the presence of spermathecae with lateral vesicles terminating in narrower ends (Fig. 38L; cf. Figs 40, 45). Females of A. dingo can be distinguished from those of A. camara by the presence of a darker body colouration and spermathecae with longer vesicles (lateral vesicle length/genitalia width>0.35) with less widely-spaced crowns (distance between crowns less than length of lateral vesicles) (Fig. 38A–L; cf. Fig. 107). Females of A. dingo can be distinguished from those of A. briggsi by the presence of spermathecae with less elongate lateral and medial vesicles (medial vesicle length/genitalia width <0.65) (Fig. 38L; cf. Fig. 37). Females of A. dingo can be distinguished from those of A. rupicola by the presence of spermathecae with straighter lateral vesicles (Fig. 38L; cf. Fig. 47). Females of A. dingo can be distinguished from those of A. longitheca by the presence of spermathecae with shorter medial vesicles (medial vesicle length / genitalia width usually <0.6), and the absence of dark patches of cuticle on the sternum, surrounding and lateral to the sigilla (Fig. 38G–I, L; cf. Fig. 43). Females of A. dingo can be distinguished from those of A. aurensis by the presence of spermathecae with more elongate, undulating medial vesicles (medial vesicle length / width ~ 6.2; cf. ~ 5.3 in A. dingo) and a lighter body colouration (Fig. 38A–L; cf. Fig. 35).

Etymology

The specific epithet ‘ dingo ’ is a noun in apposition, referencing both the type locality of the species, near Dingo in central Queensland, and also the rich honey-red colour of the live spider, reminiscent of the colour of the Australian wild dog commonly called a ‘dingo’.

Distribution and natural history

Aname dingo sp. nov. occurs in central Queensland, near the boundary between the Brigalow Belt South and Brigalow Belt North bioregions. It is known from only one location just north of the Blackdown Tableland (Fig. 7). It constructs an open, silk-lined burrow without silk outside of the entrance, at an angle, and with a hidden secondary ‘wishbone’ entrance (Fig. 7).
