A new species of Cavernocypris(Ostracoda) from Texas(U.S.A.) with a taxonomic key

Cavernocypris reddelli n. sp. is a new species of the genus Cavernocypris collected from spring waters of Texas, U.S.A.. This is the sixth species of the genus described so far. It can be distinguished from the other species of the genus by the shape and length of carapace, presence of robust marginal pore canals on right valve, number and length of setae on second antenna, shape of hemipenis, numbers of whorls on the Zenker organ, and differences in other parts of chaetotaxy. The new species was compared with other species and a new taxonomic key for the genus is presented for future studies.
