Review of species and species groups of the genus Cypridinodes (Crustacea: Ostracoda: Myodocopa: Cypridinidae: Cypridininae)

The ostracode genus Cypridinodes Brady, 1902 is reviewed, including reported ontogenetic changes, intraspecific variation and a generic diagnosis. Taxonomic notes on 20 described species are provided along with a discussion of systematic problems, particularly the inadequate description of some species, including the type of the genus. To facilitate identification of the 18 species, they are divided into four clusters.
