The taxonomic status of Uca salsisitus Oliveira, 1939 (Decapoda, Brachyura, Ocypodidae)

摘要

Although U. salsisitus Oliveira, 1939, has been placed as a junior synonym of U. rapax (Smith, 1870), a possible synonymy with Uca vocator (Herbst, 1804) has never been discarded. The retrieval of one male paratype of U. salsisitus and its confrontation with U. rapax and U. vocator shed light on the synonymy of U. salsisitus. It is shown that the type series of Uca salsisitus actually includes two species: Oliveira's original description was based upon U. vocator (Herbst), while the illustrations he provided and the retrieved male paratype correspond to U. rapax (Smith).
