Notes on the Distribution of Two Lithodid Crabs (Crustacea: Decapoda: Anomura) from off the Coast of Baja California Sur, Mexico

Abstract

Surveys designed to investigate species of potential fisheries interest <br /><br />off the coast of Baja California Sur, Mexico, have revealed the presence of two <br /><br />lithodid crabs (Crustacea, Decapoda, Anomura). One species, Lithodes couesi <br /><br />Benedict, 1895, is represented in the collections by 22 individuals and is reported <br /><br />from Mexico for the first time, extending the known range of the species south- <br /><br />ward from off San Diego, California. The second species, Glyptolithodes crista- <br /><br />tipes (Faxon, 1893), has been reported previously from mostly more southern <br /><br />localities (Peru and Chile), and is represented by a single adult male. Remarks <br /><br />on a heavy infestation of a sacculinid parasite of L. couesi and on morphological <br /><br />changes during ontogeny in G. cristatipes are included.
