'''''Metaxyonycha''''' is a genus of leaf beetles in the subfamily Eumolpinae.

==Taxonomy== ''Metaxyonycha'' was first named by Louis Alexandre Auguste Chevrolat in 1836, with the spelling "''Metazyonycha''", in Dejean's ''Catalogue of Coleoptera''. According to Bousquet and Bouchard in 2013, ''Metaxyonycha'' is an incorrect subsequent spelling of ''Metazyonycha''. However, because the subsequent spelling is in prevailing usage and is attributed to the original spelling's publication, "''Metaxyonycha''" is considered the correct spelling.<ref name="Bousquet2013"/>

In some publications for the Neotropical realm, ''Metaxyonycha'' is also known as "''Colaspis''". This was because the Czech entomologist Jan Bechyné had synonymised ''Metaxyonycha'' with ''Colaspis'', after incorrectly assuming the two had the same type species, while splitting the species of ''Colaspis'' listed in the ''Coleopterorum Catalogus'' (a beetle catalog edited by Wilhelm Junk and Sigmund Schenkling) into a separate genus known as "''Maecolaspis''". As a result, Bechyné was using the name ''Colaspis'' for what was actually ''Metaxyonycha''.<ref>{{cite journal|last=Flowers|first=W.|year=2004|title=''Colaspis''...''Maecolaspis''...''Metaxyonycha''...Whatever: an old solution to a persistent problem|url=https://www.coleopsoc.org/wp-content/uploads/2018/05/chrysomela_44Lite.pdf|journal=Chrysomela|volume=44|page=13}}</ref>
