Yuriko Jocselin Martínez, David Alfaro Siqueiros-Beltrones


Background. Most studies on benthic diatoms found in northwestern Mexico have been done along the western coast of the Baja California peninsula. Thus, few studies exist for the Gulf of California. Goals. To gather new records of benthic diatoms found in the Gulf of California. Methods. Diatom samples from sediments and rocks of the coast of Santa Rosalía, Baja California Sur, were observed under a light microscope (LM). Results. Three taxa were recorded and depicted: Caloneis liber var. bicuneata (common), Gyrosigma naja (scarce), and the new combination Entomoneis pulchra var. pulchella (scarce). Conclusions. These three taxa were recorded for the first time in northwestern Mexico.
