Integrative taxonomy of coastal (Erichson) species complex (Coleoptera, Staphylinidae).

A systematic review of the marine littoral (Erichson) along the eastern Pacific and the western Atlantic coasts including the Caribbean Sea is presented based on morphological and molecular ( and ) characters. Specimens of the species complex [, Bierig, and (LeConte)] are similar to each other, including the form and structure of the aedeagus, and they can be treated as cryptic species. Detailed micromorphological characters (SEM) and molecular analyses support the validity of these three species.
