Polyplacophoran communities (Mollusca: Polyplacophora) at Bahía de La Paz, Baja California Sur, México. Eight species of polyplacophorans have been reported from La Bahía de la Paz, Baja California Sur, Mexico. We add Lepidochitona beanii, Chaetopleura lurida, Stenoplax limaciformis, S. mariposa, Lepidozona clathrata, L. serrata and Acanthochitona arragonites, increasing the known number of species to 15. Ordination analysis of five chiton communities at the site suggests a correlation of wave exposure to species composition and diversity: communities with intermediate wave exposure have more species (richness) and higher diversity (Shannon’s index). Rev. Biol. Trop. 55 (1): 177-182. Epub 2007 March. 31.

Palavras-chave : Mollusca; Polyplacophora; chiton; Gulf of California; Bahía de La Paz; México.
