See text Maecolaspis Bechyné, 1950[3] Colaspis is a genus of leaf beetles in the subfamily Eumolpinae.

As a result, Metaxyonycha, which shared the same type species, was synonymised with Colaspis.

The species of Colaspis listed in the Coleopterorum Catalogus (a beetle catalog edited by Wilhelm Junk and Sigmund Schenkling) were then placed under Bechyné's new name, "Maecolaspis", with Chrysomela flavicornis as the type species.

[5] Many species originally placed in Colaspis were split by Bechyné into several smaller genera, such as Allocolaspis, Callicolaspis, Percolaspis, Nodocolaspis and Zenocolaspis.

[6] These extant species belong to the genus Colaspis (= Maecolaspis):[7][8] These four extinct species belong to the genus Colaspis: Synonyms: Data sources: i = ITIS,[62] c = Catalogue of Life,[63] g = GBIF,[64] b = Bugguide.net[6]
