Amphioxus, new records, distribution, central Mexican PacificResumen
Some specimens of the Californian lancelet, Branchiostoma californiense Andrews, 1893 were found in Isla Melendres, Sinaloa and Bahía Chamela, Jalisco in the Mexican Pacific. The specimens were collected with a biological dredge on sandy bottoms. Some morphometric and meristic characters of the founded specimens are described and discussed herein. This is the first record of the species for the Bahía Chamela in the central Mexican Pacific and second for the Sinaloa state into the Gulf of California, confirming their distribution along the Eastern Pacific from California coast, USA to Panama. However, an extensive area of the southern Mexican Pacific (~2800 km from Colima to Chiapas) doesn’t present records of this species maybe due to the lack of sampling effort on this group in this area.
