Diagnosis

Males of A. ammolithica sp. nov. can be distinguished from all species for which males are known except A. barakula sp. nov. and A. lambkinae 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. 49A–Q View Fig ). Males of A. ammolithica can be distinguished from those of A. lambkinae by the presence of a narrower sternum (sternum length / width> 1.4) and a less pronounced heel on metatarsus I ( Fig. 49A–Q View Fig ; cf. Fig. 53 View Fig ). Males of A. ammolithica can be distinguished from those of A. barakula by the presence of more medially-positioned posterior sternal sigilla (distance of posterior sigilla from sternum centre /sternum length ~ 0.17; cf. ~ 0.26 in A. barakula ), and a thicker tibia I (tibia I length / width ~3.2; cf. ~ 3.5 in A. barakula ) ( Fig. 49H, P View Fig ; cf. Fig. 50 View Fig ).

Females of A. ammolithica sp. nov. are unknown.

Etymology

The specific epithet ‘ ammolithica ’ is an adjective formed from the Greek ‘ ammos ’, meaning sand, and ‘ lithos ’ meaning stone, in reference to the distribution of this species in the Mount Moffatt section of Carnarvon National Park, an area with sandy soil and sandstone outcrops.

Distribution and natural history

Aname ammolithica sp. nov. occurs in central Queensland, in the Brigalow Belt South bioregion, in the Mount Moffatt region of Carnarvon National Park ( Fig. 8 View Fig ). 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 View Fig ).
