New Species of Rimicola from California
A new species of clingfish (Gobiesocidae) in the genus Rimicola, that exhibits unique sexual dimorphisms, is described from the Santa Barbara Islands, California. It is most closely related to two other California Rimicola species that are also sexually dimorphic. Now that a Rimicola species described from the Caribbean has been determined to belong elsewhere, the genus reverts to its original status as a northeastern Pacific endemic.Abstract
