Fidia

The name "Fidia" was first used in 1836 by the French entomologist Pierre François Marie Auguste Dejean in his Catalogue des Coléoptères, listing two species from the New World, F. lurida and F. murina. No etymology was given for the name "Fidia", and some later entomologists have considered it as an arbitrary combination of letters. Because no description or indication was given for either of the two species in Dejean's catalogue, they are considered nomina nuda, and likewise Fidia Dejean is also considered a nomen nudum.[2]

In 1861, Victor Motschulsky described a new species of beetle from Japan with the name Fidia atra. Motschulsky's species description, in combination with the generic name Fidia, consititutes an indication for the latter, thereby making the name Fidia available.[2]

In 1863, Joseph Sugar Baly provided a description of Dejean's Fidia and Fidia lurida, making both names available (and making Fidia Baly, 1863 a junior homonym of Fidia Motschulsky, 1861). In the same work, Baly also established the Old World genera Lypesthes, with Motschulsky's Fidia atra as the type species, and Leprotes, which was later treated as a junior synonym of Lypesthes. Following Baly's work, the name Lypesthes was consistently used for the Old World genus group based on Fidia atra, while Fidia was consistently used for the New World genus group based on Fidia lurida.[2][6]

An application to suppress Fidia Motschulsky, 1861 (with the year incorrectly given as "1860") and conserve usage of Fidia Baly, 1863 and Lypesthes Baly, 1863 was submitted to the ICZN in 2006. This proposal was rejected by the commission in 2009, upholding the priority of Fidia Motschulsky, 1861.[7] Following this ruling, Fidia Baly, 1863 was renamed to Neofidia in 2020.[6]
