Figs 14, 112

Diagnosis

Males of A. insolita 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), and the presence of a short embolus (embolus length/bulb length <1.5) that is straight (and thus looks relatively long), wide and flattened (Fig. 112L–M).

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

Etymology

The specific epithet ‘ insolita ’ is a Latin adjective meaning ‘unusual, strange’ or ‘rare’, referencing the strangeness of the genital morphology of this species, and its rarity in collections.

Distribution and natural history

Aname insolita sp. nov. occurs in south-eastern Queensland, in the Brigalow Belt South and New England Tablelands bioregions. It is known from three locations, all just west of the Great Dividing Range, from Stanthorpe north to Gayndah (Fig. 14). The form of burrows constructed by spiders of this species is unknown.
