Species are listed alphabetically by genus. Introduced species are indicated by a * following the specific epithet. Valid names are listed with their author and year of description. Morphospecies, indicated by sp., denotes a form that is morphologically distinct from all others listed for that genus. The # sites column indicates the number of locations a form was sampled from and the Habitat column notes the habitat where each form was found: DF: dry forest and LE: low elevation (Cabo Rojo beach site and the shore of Lake Oviedo). Specimen data, including geolocations, are available online at MCZbase [19].
