Diagnosis
Males of A. mariala sp. nov. can be distinguished from all species for which males are known except A. albicula sp. nov. by a small body size (carapace length <4.0 mm), the presence of a short embolus (embolus length/ bulb length <1.5) that is very thin and sharp, a relatively thin metatarsus I (metatarsus I length / width>4), and the absence of thorn-like setae on the retrolateral palp tibia (Fig. 100A–Q). Males of A. mariala can be distinguished from those of A. albicula by the absence of an embolic apophysis on the copulatory organ, adjacent to the embolus (Fig. 100L–M; cf. Fig. 99).
Females of A. mariala sp. nov. are unknown.
Etymology
The specific epithet ‘ mariala ’ is a noun in apposition, referencing Mariala National Park, near Charleville in central Queensland, where the type specimen was found.

Distribution and natural history
Aname mariala sp. nov. occurs in south-western Queensland, in the Mulga Lands bioregion, where it is known from one location in Mariala National Park (Fig. 13). The form of burrows constructed by spiders of this species is unknown.
