Diagnosis
Males of A. albicula sp. nov. can be distinguished from all species for which males are known except A. mariala 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. 99A–Q). Males of A. albicula can be distinguished from those of A. mariala by the presence of a small embolic apophysis on the copulatory organ, adjacent to the embolus (Fig. 99L–M; cf. Fig. 100).
Females of A. albicula sp. nov. are unknown.
Etymology
The specific epithet ‘ albicula ’ is an adjective formed from the Latin ‘ albus ’, meaning ‘white’, and the suffix ‘- cula ’, which is associated with diminutiveness, referencing the spider’s physical appearance.

Distribution and natural history
Aname albicula sp. nov. occurs in north-western New South Wales, in the Mulga Lands bioregion, in Ledknapper Nature Reserve (Fig. 13). The form of burrows constructed by spiders of this species is unknown.
