First record of subterranean freshwater gastropods (Mollusca, Gastropoda, Cochliopidae) from the cenotes of Yucatan state

The biospeleological investigations of several cenotes in the eastern region of Yucatan state, Mexico, during January 2018 yielded, among other invertebrates, two new truncatelloid gastropod species described herein as Mexicenotica xochii gen. n. et sp. n. and Pyrgophorus thompsoni sp. n. Both species represent the first record of stygobiont gastropod species from the cenotes of Yucatan indicating the high biodiversity potential of the studied area.
