Diagnosis

Males of A. namoi sp. nov. can be distinguished from all species for which males are known by a moderate to large body size (carapace length> 4.0 mm), the presence of a short embolus (embolus length/ bulb length <1.5) that has a bend near the base before a straight distal section, and a long proximal excavation (excavation length / metatarsus length ~ 0.5) on metatarsus I ( Fig. 115L–Q View Fig ).

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

Etymology

The specific epithet ‘ namoi ’ is a noun in apposition, referencing the distribution of this species around the Namoi River in northern New South Wales.

Distribution and natural history

Aname namoi sp. nov. occurs in northern New South Wales, in the Darling Riverine Plains bioregion, where it is known from two locations, near Pilliga and Walgett ( Fig. 14 View Fig ). The form of burrows constructed by spiders of this species is unknown.
