Genus of leaf beetles
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 et al. 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.
[1]
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 .
