Ontogeny of Deeveya medix Kornicker, 1990, collected in anchialine and marine caves in the Bahama Islands (Ostracoda: Halocypridae: Deeveyinae)

Four juvenile instars of Deeveya medix (Instars I, II, III, and V) from marine caves and blue holes in the Bahamas are described and illustrated. The ontogeny of the species is compared with that of D. spiralis Kornicker & Iliffe, 1985, and D. bransoni Kornicker & Palmer, 1987 and found to be similar. Criteria are presented for identifying stages of species of Deeveya. Each lamella of the furca of known species of Deeveya bears 3 claws on instar I, 4 on instar II, 5 on instar III, 6 on instar IV, and 7 on instar V and the adult.
