Viracucha mammifer (Mello-Leitão, 1939) comb. nov.

Acanthoctenus mammifer Mello-Leit „o, 1939: 528, figs 11–13 (male holotype from S„o Paulo, Brazil, deposited in IBSP 368, examined).— World Spider Catalog 2020.

Note. The transference of Acanthoctenus mammifer to Viracucha is established by the following characters: embolus with laminated base and median apophysis massive (Mello-Leit„o, 1939: figs 11–13). Males of Acanthoctenus were here diagnosed by the short and cylindrical embolus and the elongated and thin median apophysis.
