SYSTEMATIC LIST UPDATE OF THE CLASS GASTROPODA IN THE CENTRAL AND NORTHERN COAST OF SONORA, GULF OF CALIFORNIA

Abstract

Diversity studies and research have included members of the class Gastropoda from the Gulf of California. Still, the majority have been researched in a rudimentary or secondary way, with literature not specific to the region causing discrepancies in the nomenclature of the taxa. This could affect the information on some taxa. It could also affect the malacological knowledge of the region. Therefore, an updated fauna inventory was built for 71 families of the class Gastropoda on the coast of Sonora based on latitudinally-referenced information of 3261 records of species names from the region (27° N – 31° N), obtained from official electronic databases and physical revision of malacological material from a museum. Depuration and taxonomic updates were performed when the obtained information was compared with the World Register of Marine Species platform. As a result, 26.64% of the species’ names showed status updates, resulting in 713 valid names of gastropods. The latitudinal distribution highlighted 27° N and 31° N with the greatest data and species diversity. The easy access to port cities (in the previously mentioned latitudes) makes them suitable points for scientific research since they have demonstrated a strong bias compared to intermediate latitudes.
