Range extension of brachyuran crabs along the Baja California coast, Mexico (Crustacea: Decapoda)

Abstract

 The study of brachyuran crabs collected from intertidal areas of the upper Gulf of California and the west coast of the Baja California peninsula, at Tortugas Bay, Baja California Sur, has produced a northern range extension for the following species: Hemus fineganae Garth, 1958; Microphrys platysoma (Stimpson, 1860); Eriphia squamata Stimpson, 1859; Xanthodius sternberghii Stimpson, 1859; Uca princeps princeps (Smith, 1870); and Euphylax robustus A. Milne-Edwards, 1874. We present each species and include an analysis of their previous distribution, habitat, new localities and, in some cases, notes on the breeding period.
