Abstract:
Collecting much-needed information on the taxonomy, distribution, and ecology of cavedwelling
shrimp is vital for addressing the urgent challenges in conservation biodiversity in
fragile cave ecosystems. Caridina unicolor 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
unicolor sp. nov. differs from epigean congeners by its smaller eyes which ranges 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 unicolor 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 suggests that it should be categorized as Critically Endangered (CR) under the
