Colaspis Purpurea

''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, "''Maecolaspis''", with ''Chrysomela flavicornis'' as the type species. These errors were corrected by W. J. Brown in 1961, who synonymized ''Maecolaspis'' with ''Colaspis''. Despite this, Bechyné continued to use ''Maecolaspis'' as valid, while Doris Holmes Blake published several papers on ''Colaspis'' without mentioning Bechyné's ''Maecolaspis''. This effectively created two systems for the taxonomy of the Neotropical leaf beetles, which has frequently confused those studying the Neotropical Eumolpinae.

Many species originally placed in ''Colaspis'' were split by Bechyné into several smaller genera, such as ''Allocolaspis'', ''Callicolaspis'', ''Percolaspis'', ''Nodocolaspis'' and ''Zenocolaspis''. The genus requires further subdivision.
