*Note: not all of the species are valid and errors in synonomy will be present. We do our best to keep up to date, but it is difficult to locate all changes. Also, not all of the authors' names are included, and may not be correct with respect to (brackets) for generic name changes. Please excuse any mistakes, as this species list is a meant as a first guide only.
