Abstract

The Diabroticites is a subtribe of the Galerucinae that now includes an array of fifteen genera for the beetles formerly included in the large neotropical genus Diabrotica Chevrolat. About 900 species have been described and there are at least that many more undescribed. The group is of rather recent origin and is still rapidly evolving. The Diabroticites are almost entirely Neotropical in distribution and the greatest diversity of species is reached in the tropical areas of South America. A few species extend the distribution of the group into temperate regions in both North and South America. Seventeen species are found in the United States and only nine species in the eleven Western States.
