Diagnosis

Males of A. litoralis sp. nov. can be distinguished from all species for which males are known by a small body size (carapace length <4.0 mm), the presence of a short embolus (embolus length / bulb length <1.5), a triangular tibial spur with a long megaspine (megaspine length / tibia length>0.3), and short thorn-like setae along the retrolateral edge of the asetose depression ( Fig. 114L–Q View Fig ).

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

Etymology

The specific epithet ‘ litoralis ’ is a Latin adjective meaning ‘coastal’ or ‘pertaining to the shore’, in reference to the distribution of this species on the central Queensland coast and coastal islands.

Distribution and natural history

Aname litoralis sp. nov. occurs in central-eastern Queensland, in the Central Mackay Coast bioregion (including on at least one offshore island), near the town of Proserpine and its surroundings ( Fig. 14 View Fig ). The form of burrows constructed by spiders of this species is unknown.
