The extant genera of the spinicaudatan clam shrimp family Limnadiidae are revised using morphological criteria built on previously published molecular analyses. The combined analyses demonstrate the presence of eight well defined genera, two of which are new to science and one (Paralimnadia) that is resurrected. We present the description of the new genus Afrolimnadia and the new genus and species Calalimnadia mahei n. sp. described from Mauritius Island. Both molecular and morphological data strongly support eight genera: Afrolimnadia n. gen., Calalimnadia n. gen., Eulimnadia, Imnadia, Limnadia, Limnadopsis, Metalimnadia and Paralimnadia.
