Diagnosis. The diagnostic features of the genus are the same as those of the type species Mexicenotica xochii sp. n. The minute size with tear shaped shell and expanded oval aperture with a fragile flaring corrugated margin distinguish the new genus from any other related genera of Cochliopidae or Pomatiopsidae . Etymology. Named after the country of origin and cenotes, the specific vertical sinkhole karstic formations of Yucatan's plateau, whose phreatic waters and aquifers host the new genus.
