Abstract

The genus Praon is revised. Thirteen North American species north of Mexico are recognized, including one new to science: P. carinum sp. nov. Praon cerasaphis (Fitch) and P. coloradense Ashmead are retained as Species inquirende. The female of P. alaskense Ashmead and the male of P. artemisaphis Smith are described for the first time. Praon nanus Baker, P. exsoletum palitans Muesebeck, P. aguti Smith, and P. negundinus Smith are placed in synonymy. The genus Parapraon Stary is considered a synonym of Praon Haliday. A generic diagnosis of Praon Haliday is given, and a key, diagnoses, and illustrations of North American species are provided.
