Anchialine systems are coastal groundwater habitats around the world which host a unique community of cave adapted species (stygobionts). Such communities are expected to be separated by haloclines into either fresh or saline groundwater communities, hence climate changes (e.g.

- The Yucatán Peninsula has unique aquifer ecosystems with diverse anchialine shrimp species, particularly from the Typhlatya genus, with four endemic species, three of which are federally protected in Mexico.
- A comprehensive analysis combining molecular, morphological, and environmental data reveals significant species identity conflicts and newly identified genetic lineages among these shrimp.
- The findings highlight the evolutionary adaptations of these species to different salinity levels and stress the importance of using interdisciplinary methods to evaluate biodiversity in complex aquatic environments.
New records of 14 stygobiont crustacean species pertaining to six Malacostraca orders from 32 cenotes are presented, with their associated caves of the state of Yucatan, Mexico, together with an individual account for each species. Species composition of most of the investigated cenotes is examined for the first time. A thermosbaenacean and two amphipod species were not formally recorded to the cenote ecosystems of the state of Yucatan prior to our research.

Morphology was studied under light microscopy and with scanning electron microscopy. Morphological description is complemented with mitochondrial cytochrome c oxidase subunit I (COI) sequences as barcodes, with affinities to the related taxa and with notes on the species' ecology.
