First record of glycera guatemalensis and G. sphyrabrancha (Annelida: Glyceridae) from Western México por De León González, Jesús Ángel, Tovar Hernández, María Ana, Torres Manríquez, Iliana, García Garza, María Elena

“…Methods: An analysis of the glycerides of the Pacific coast of Mexico was carried out, finding two species that were collected, one of shrimp trawl at a depth of 18 meters off Puertecitos, Baja California, as well as by manual sampling in the intertidal zone of Concepción Bay, Baja California Sur in the Gulf of California. For their taxonomic determination, morphological characters of greater relevance for their identification were examined, such as jaws, aileron shape, parapodia, chaetae, and the type of pharyngeal papillae. …”
