Fidia
# Fidia

Fidia (formerly known as Lypesthes) is a genus of leaf beetles in the subfamily Eumolpinae. It is distributed in East Asia, Southeast Asia and Africa.

## Taxonomic history

In 1861, Victor Motschulsky described a new species of beetle from Japan with the name Fidia atra. In 1863, Joseph Sugar Baly designated Fidia atra as the type species of a newly established genus with the name Lypesthes. In a 2008 review of the New World genus Fidia Baly, 1863, it was determined that Motschulsky's species description made the name Fidia available first, meaning that Lypesthes Baly, 1863 is a junior synonym of Fidia Motschulsky, 1861 and that Fidia Baly, 1863 is a junior homonym.

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. Following this ruling, Fidia Baly, 1863 was renamed to Neofidia in 2020.
