Abstract:
Collecting much-needed information on the taxonomy, distribution, and ecology of cave-dwelling
shrimp is vital for addressing the urgent challenges in conservation biodiversity in fragile cave ecosystems.
Caridina incolor sp. nov., a new atyid shrimp from an underground stream of Yaoshui Cave, Daqikong
scenic area, Libo County, Guizhou Province, southwestern China is described based on morphology and
DNA analysis (mitochondrial COI). Caridina incolor sp. nov. differs from epigean congeners by its smaller
eyes which range from reduced to completely blind; colorless body and appendages; long stylocerite and
sixth abdominal segment; and relatively large eggs. In comparison to other cave species, Caridina incolor
sp. nov. presents a long rostrum and stylocerite; slender sixth abdominal segment; and unique shape of
the appendix masculina. Data on the habitat, ecology, and levels of threat are provided and suggest that it
should be categorized as Critically Endangered (CR) under the current IUCN criteria.
