Remarks.

In 2007, Miller declared this species a nomen dubium: "The otherwise Palearctic genus Minyriolus was represented in the Neotropics by M. australis Simon 1902; specimens of M. australis could not be located and it is considered nomen dubium". The specimen deposited in the Hamburg collection is indisputably part of the type series.

Type material.

Lectotype ♀ designated here (ZMH-A0000756). Abdomen detached from body.

Taxonomic note.

The genus Minyriolus is composed of three Palearctic species ( World Spider Catalogue 2018). Even though its is unlikely that this species belongs to this genus (as already indicated by Simon in the original publication, the generic name is written with a “?”), we argue that is should be left in this genus, pending taxonomic revision.
