Metaxyonycha
''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. 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 "''Maec ...

Colaspis
''Colaspis'' is a genus of leaf beetles in the subfamily Eumolpinae. It is one of the largest genera in the subfamily, containing over 200 species, and it is known from both North and South America. A number of species from this genus are considered to be pests, such as the grape colaspis (''Colaspis brunnea''). Some species are known from the fossil record from the Eocene of Colorado in the United States. Taxonomy In some publications for the Neotropical realm, ''Colaspis'' is also known as ''Maecolaspis''. This alternative name was created by the Czech entomologist Jan Bechyné in 1950, due to an error relating to the type species of ''Colaspis'': Bechyné incorrectly considered ''Colaspis testacea'' to be the type species of ''Colaspis'', rather than ''Chrysomela flavicornis''. As a result, ''Metaxyonycha'', which shared the same type species, was synonymised with ''Colaspis''. The species of ''Colaspis'' in the Junk-Schenkling catalog were then placed under Bechyné's new name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
