A revision of the genus Colletes in America north of Mexico (Hymenoptera, Colletidae)

Abstract

The bee genus Collates abounds in America north of the tropic of Cancer and is widely distributed throughout the world, with the exception of Australia. This study is limited to those species occurring in America north of Mexico, for material from the Central American countries is meagre and areas of collection disjunct.

The work is primarily of a systematic nature and contributes little to an evolutionary or phylogenetic study of the genus. However, in conjunction with Noskiewicz’s (1936) treatise on the Palearctic members of the genus plus a critical treatment of the Central American fauna, it should form a suitable basis tor the inauguration of such a project.
