Anatextrix, Kaya & Zamani & Yağmur & Marusik, 2023

Kaya, Rahsen S., Zamani, Alireza, Yagmur, Ersen Aydin & Marusik, Yuri M., 2023, A new genus of Textricini Lehtinen, 1967 (Araneae, Agelenidae) from Anatolia, ZooKeys 1151, pp. 31-45 : 31

Genus Anatextrix gen. nov.

Type species.

Anatextrix spectabilis sp. nov.

Etymology.

The generic epithet is a combination of Anatolia and Textrix ; gender feminine.

Diagnosis.

The new genus differs from all other genera of Textricini by having a strongly modified male palpal femur with two outgrowths and two bulges (vs one or none), presence of the palpal prolateral tibial apophysis (Pt) and the cymbial prolateral fold (Cf) (vs lacking), the straight mesal part of the embolic base (vs round) (cf. Figs 2A , 4A , 8A-F ), and by having a thin septum in the epigyne (vs absent). Furthermore, the female of Anatextrix spectabilis sp. nov. differs from those of Textrix by having no epigynal fovea and scape (vs present). From the females of the two other genera, the female of this species differs by the anterior position of the receptacles (vs mesal or posterior).
