Diagnosis
Males of A. longitheca can be distinguished from all species for which males are known except A. aurensis sp. nov., A. briggsi sp. nov., A. eddieorum sp. nov., A. hughenden sp. nov., A. mulgana sp. nov., A. rupicola sp. nov., and A. warrego sp. nov. by a moderate to large body size (carapace length>4.0 mm), the presence of a long embolus (embolus length/ bulb length>1.5) that has a relatively wide basal section tapering into an attenuate, sinuous distal section after about 0.4 of length, and the absence of a prominent sharp heel on metatarsus I (as in the pallida -complex) (Fig. 42L–M). Males of A. longitheca can be distinguished from those of A. aurensis, A. briggsi, A. hughenden, A. mulgana, and A. rupicola by the presence of a tibia I that stays about the same width from the proximal end to the base of the tibial spur when in lateral view (Fig. 42P; cf. Figs 34, 36, 41, 44, 46). Males of A. longitheca can be distinguished from those of A. warrego by the presence of a thicker palp tibia (palp tibia length /width <3) (Fig. 42J–K; cf. Fig. 48). Males of A. longitheca can be distinguished from those of A. eddieorum by the presence of a longer, more curved embolus (embolus length / bulb length ~2.7; cf. ~ 2.2 in A. eddieorum) (Fig. 42L–M; cf. Fig. 39).
Females of A. longitheca can be distinguished from all species for which females are known except A. aurensis sp. nov., A. briggsi sp. nov., A. camara, A. dingo sp. nov., A. eddieorum sp. nov., 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. 43L). Females of A. longitheca can be distinguished from those of A. eddieorum and A. mulgana by the presence of spermathecae with lateral vesicles terminating in narrower ends (Fig. 43L; cf. Figs 40, 45). Females of A. longitheca can be distinguished from those of A. aurensis and A. dingo by the presence of spermathecae with long medial vesicles (medial vesicle length/ genitalia width> 0.6) and dark patches of cuticle on the sternum, surrounding and lateral of the sigilla (Fig. 43G–I, L; cf. Figs 35, 38). Females of A. longitheca 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. 43A–L; cf. Fig. 107). Females of A. longitheca can be distinguished from A. briggsi by the presence of spermathecae with less elongate lateral and medial vesicles (medial vesicle length /genitalia width <0.65) (Fig. 43L; cf. Fig. 37). Females of A. longitheca can be distinguished from those of A. rupicola by the presence of spermathecae with straighter lateral vesicles (Fig. 43L; cf. Fig. 47).

Distribution and natural history
Aname longitheca occurs in the ‘Gemfields’ of central Queensland, in the Brigalow Belt North bioregion, where it is known only from near the town of Rubyvale (Fig. 7). It constructs an open, silk-lined burrow without silk outside of the entrance, on an angle, and with a hidden secondary ‘wishbone’ entrance (Fig. 7).
