Taxonomy and species

There is evidence for hybridization between sympatric taxa, requiring care when interpreting molecular phylogenetic analyses that do not use a large number of specimens. As of March 2022, the Integrated Taxonomic Information System lists the genus ''Caridina'' as having 340 species. These include the following species: *'' Caridina ablepsia'' Guo, Jiang & Zhang, 1992 *'' Caridina acuta'' Liang, Chen & W.-X.
