Abstract

Two new species of gymnosomatous mollusks from the central portion of the Gulf of California, Mexico are described based on radular characteristics. Pneumoderma cicimarensis sp. nov., has a similar morphology to Pneumoderma atlanticum pacificum (Oken, 1815), but differs in the presence of one lobe on the median portion of the wing, a lack of chromatophores in the body and the shape of the radular teeth. The second species Pneumodermopsis tacoi sp.nov., has a similar radula to Pneumodermopsis ciliata (Gegenbaur, 1855) but differs significantly in the number of rows of the radula and the shape of the central tooth.
