Diagnosis

Males of A. broadwater sp. nov. can be distinguished from all species for which males are known except A. flexicaudula sp. nov. by a small body size (carapace length <4.0 mm), and the presence of a long embolus (embolus length / bulb length>1.5) that is reflexed relative to the bulb and relatively straight ( Fig. 101K–P ). Males of A. broadwater can be distinguished from those of A. flexicaudula by presence of a thinner tibia I (tibia length/ width ~ 3.1; cf. ~ 3.5 in A. flexicaudula ) with a more distally-positioned tibial spur (length to spur/ tibia length ~ 0.5; cf. ~ 0.4 in A. flexicaudula ) ( Fig. 101P ; cf. Fig. 102 ).

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

Etymology

The specific epithet ‘ broadwater’ is a noun in apposition, referencing Lake Broadwater Conservation Park, just west of Dalby, the type locality of this species.

Distribution and natural history

Aname broadwater sp. nov. occurs in southern Queensland, in the Brigalow Belt South bioregion. It is only known from the type locality, in Lake Broadwater Conservation Park, near the town of Dalby ( Fig. 13 ). The form of burrows constructed by spiders of this species is unknown.
