New Species and New Records of the Weevil Genus Ceutorhynchus Germar (Coleoptera, Curculionidae) from the U.S.A.

Abstract

Ceutorhynchus balciunasisp. n., closely related to the Eastern Siberian and Far Eastern C. matisi Korotyaev, is described from Oregon and California. Ceutorhynchus fallisp. n. from Alaska (Nome) is related to these two species but differs from both in a set of morphological characters typical of the Arctic and alpine weevils and may be considered a truly Arctic form. Ceutorhynchus ? kolymensis Kor., a species very close to the mostly Western Palaearctic pair of species with characteristic coarse dorsal sculpture, C. puncticollis Boh. and C. talickyi Kor., is recorded from the Rocky Mountains in Colorado (U.S.A). Ceutorhyncuis barkalovi Kor., a circumpolar species previously known in North America only from Yukon (Canada) is also recorded from the Rocky Mountains in Colorado (U.S.A). New state records of Ceutorhynchus moznettei Fall and C. downiei Colonnelli are given.
