Pyrrhalta
''Pyrrhalta'' is a genus of beetles in the leaf beetle family, Chrysomelidae. Species are distributed throughout much of the world, including much of the Northern Hemisphere and the Australian region.Nie, R. E., et al. (2013)Notes on black elytron species of ''Pyrrhalta'' Joannis and the description of a new species from China (Coleoptera, Chrysomelidae, Galerucinae).''ZooKeys'' 289 41-56. The taxonomy (biology), taxonomy of the genus is not clear. Species are separated from those of other genera by the sometimes inconsistent comparison of questionable characters, such as the distribution of minute hairs. There is also little agreement on how to divide the group into subgenus, subgenera. Former subgenera such as ''Xanthogaleruca'' are treated as separate genera by some authors, but not accepted as such by others. A definition of the genus used by some authors includes characters such as a hairy prothorax, pronotum and elytrum, elytra, gena (the spaces below the eyes) longer than ...
