Revision of the Subfamily Criocerinae (Chrysomelidae) of North America North ofMexico

摘要

The subfamily Criocerinae is a large and nearly worldwide group of roughly 1,500described species. The North American species are medium-sized leaf beetles (2.7-8.0 mm long) that feed on no less than seven different families of plants. This study is intended to consolidate existing information on the North American species of the subfamily; describe new taxa; provide a description for each species; correct generic assignments where necessary; establish new synonymy as needed; redefine known species; and provide keys, illustrations, and maps to aid in identifications. Twelve species are herein described as new, and 5 new synonyms and 11 new combinations are presented. One species is newly recorded from the United States. Two former subspecies are raised to the species level. This work brings to 44 the number of North American species.
