Diagnosis
Males of A. lambkinae sp. nov. can be distinguished from all species for which males are known except A. ammolithica sp. nov. and A. barakula 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 is relatively straight, a triangular tibial spur (rather than more digitiform), and a thin metatarsus I (metatarsus I length/ width>3.9) with an unpronounced heel (Fig. 53A–Q). Males of A. lambkinae can be distinguished from those of A. ammolithica and A. barakula by the presence of a wider sternum (sternum length /width ~ 1.3; cf.> 1.4) and a more pronounced heel on metatarsus I (Fig. 53A–Q; cf. Figs 49–50).
Females of A. lambkinae sp. nov. can be distinguished from all species for which females are known except A. barakula sp. nov., A. braemar sp. nov., and A. truncata 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. 54A–L). Females of A. lambkinae can be distinguished from those of A. barakula and A. braemar by the presence of spermathecae with lateral vesicles without distinct, widened crowns (Fig. 54L; cf. Fig. 51). Females of A. lambkinae can be distinguished from those of A. truncata by the presence of spermathecae with more elongate lateral vesicles (lateral vesicle length / width ~ 3.6; cf. ~ 1.6 in A. truncata) and strongly bent medial vesicles with distinct crowns (Fig. 54L; cf. Fig. 55).
Etymology
The specific epithet ‘ lambkinae ’ honours Dr Christine Lambkin, for her contributions to Australian entomology and biodiversity science. Christine was involved in collecting several specimens of this species.

Distribution and natural history
Aname lambkinae sp. nov. occurs in central Queensland, in the Brigalow Belt South bioregion, extending from the Mount Moffatt and Upper Warrego regions of Carnarvon National Park and Carnarvon Station Reserve in the west, to near the Beilba region in the east (Fig. 8). The form of burrows constructed by spiders of this species is unknown, but is likely to be similar to that of other barakula -complex species (Fig. 8).
