Abstract

The eight known North American species of Microrhopala infest Solidago, Aster, and other compositaceous plants. Descriptions and keys to species and subspecies are given. Microrhopala rileyi is named as a new species from Missouri, M. hecate (Newman) is removed from synonymy with M. cyanea (Say), and M. cyanea is reduced to a subspecies of M. excavata (Olivier). Lectotypes are designated for taxa described originally in the genus Hispa, i.e., Hispa vittata, H. xerene, and H. erebus, and neotypes are designated for H. excavata and H. cyanea. Phylogenetic relationships are discussed.
