Astacinga

Astacinga is a genus of freshwater crabs belonging to the family Pseudothelphusidae. These crabs are endemic to Mexico, primarily found in the states of Veracruz and Oaxaca.

Astacinga crabs are characterized by their relatively small size and preference for aquatic habitats such as streams, rivers, and caves. They play an ecological role as detritivores, feeding on decaying organic matter and contributing to nutrient cycling within their ecosystems.

The taxonomy of the genus has undergone revisions, and the number of recognized species within Astacinga may vary depending on the source. Factors like habitat loss and water pollution pose potential threats to the conservation of these crab species. Further research is needed to fully understand the distribution, population status, and specific ecological requirements of each species within the genus Astacinga.
