THE SUBFAMILY DONACIINAE IN UTAH (INSECTA: COLEOPTERA: CHRYSOMELIDAE)

Shawn M. Clark1,3, Andrew B. Olsen2, and Mark H. Goodman1,2

ABSTRACT.—Information is presented dealing with the western North American species of the subfamily Donaciinae, with emphasis on data from the state of Utah. Dichotomous keys and short diagnoses are provided to enable identification of genera and species. Previously published records from Utah are summarized. For each species, the overall North American distribution is summarized, and detailed records are given for Utah. Reported host plants for each species are also listed.

Key words: Chrysomelidae, Donaciinae, Donacia, Plateumaris, Utah.
