The present report updates the distribution of Armases magdalenense <br /><br />(Rathbun, 1918), Hemigrapsus oregonensis (Dana 1851) and Goetice americanus <br /><br />Rathbun 1923 along the Baja California coast. Previous records of Tetragrapsus <br /><br />jouyi (Rathbun 1893) to the rocky intertidal of Punta Pelicano, near Puerto Pen- <br /><br />asco, Sonora, are rejected. These were based on misidentifications of specimens <br /><br />of G. americanus. Tetragrapsus jouyi is known from salt marsh areas of Guaymas, <br /><br />Sonora, and Bahia de Los Angeles, Baja California (new locality). The presence <br /><br />of Hemigrapsus nudus in the Gulf of California is not confirmed. It undoubtedly <br /><br />occurs on the west coast of the Baja California Peninsula northward to Alaska, <br /><br />U.S.A. An identification key to the Varuninae of the East Pacific is provided.
