Taxonomy

The species was first described in 1901, as Metaphidippus pernix, by F. O. Pickard-Cambridge.^[3] In 1911, Alexander Petrunkevitch decided to transfer the species to the genus Dendryphantes. However, Dendryphantes pernix already existed as the name for a different species (Dendryphantes pernix Peckham & Peckham, 1901, now Beata pernix^[4]). Accordingly, Petrunkevitch coined the replacement specific name pernotus.^[5] In 1971, Jerzy Prószyński returned the species to Metaphidippus under its original name Metaphidippus pernix.^[6][1] The species has also been wrongly called Metaphidippus pernotus (Petrunkevitch, 1911), as in earlier versions of the World Spider Catalog.^[2]
