Corrigenda: Morphological and molecular evidence support the taxonomic separation of the medically important Neotropical spiders Phoneutria depilata (Strand, 1909) and P. boliviensis (F.O. Pickard-Cambridge, 1897) (Araneae, Ctenidae). ZooKeys 1022: 13–50. https://doi.org/10.3897/zookeys.1022.60571

In a recent publication (Hazzi & Hormiga 2021) we demonstrated that there are two species under the name of the ctenid spider Phoneutria boliviensis (F.O. Pickard-Cambridge, 1897) and used the name Phoneutria depilata (Strand, 1909) for this second species, which in the past had been treated as a junior synonym of boliviensis. We proposed that “Ctenus peregrinoides Strand, 1910” was a new junior synonym of Phoneutria depilata. We note here that such synonymy is an error. Strand did not use the name “Ctenus peregrinoides” as valid when he proposed it (valid as opposed to, for example, “if this were a new species, here is a name”), which means that his provisional name is not available for nomenclatural purposes. Thus, formally treating “peregrinoides” as a junior synonym is inconsequential because Strand’s name is not available in a nomenclatural sense
