Tetralycosa

Fauna Portal Genus Number: 2548

(after Framenau & Hudson 2017): Males of Tetralycosa differ from other lycosid genera within the Artoriinae by the combination of the following characters: tegular apophysis originating apically on tegulum and basally curved, opposing an apico-medially directed pointy (lobed in T. halophila) protrusion on the retrolateral section of the tegulum; basal lobe of tegular apophysis present; terminal apophysis forms a shaft for the resting embolus; female epigyne variable: with a wide median septum that displays an inverted T-shaped dark central pattern, or a round to oval opening with anterior notch.

Tetralycosa includes exclusively halotolerant wolf spiders, most of which can be found on and around salt lakes. Tetralycosa arabanae occurs mainly around Artesian mound springs and T. oraria is a coastal beach and sand dune species around the southern coast of Australia.
