Female Colletes daviesianus, copyright Donald Hobern. In his 2007 edition of The Bees of the World, Charles Michener recognised five subfamilies within the Colletidae.The Colletinae were distinguished from three of these subfamilies by their retention of a covering of dense hair over the body (from the last subfamily, the Diphaglossinae, they differ in features of the glossa and wing venation).
