Deeveya jillae Kornicker & Iliffe, 1989
Taxonomic Characterization: Carapace oval in lateral view except for straight dorsal margin and slightly concave anterior margin. Right valve with small tubercle on dorsal margin near posterior end. Carapace viewed with transmitted light with coarse, bright disks; walls of reticulations within shell also visible with transmitted light (Kornicker & Iliffe, 1989; Kornicker, Yager & Williams, 1990).
Disposition of Specimens: National Museum of Natural History, Smithsonian Institution, catalog numbers USNM 193298-193300.
Ecological Classification: Stygobitic
Size: Estimated adult carapace length ranges from 1.32 to 1.35 mm (Kornicker, Yager & Williams, 1990:48).
Number of Species in Genus: Seven, all from anchialine caves
Deeveya: genus range
Species Range: Known only from Hatchet Bay Cave, Hatchet Bay, Eleuthera Island, Bahamas.
Habitat: Anchialine Limestone Caves
Ecology: Collected at depths of 0-3 m in waters with a salinity of 32 ppt. Additional fauna found were: an ostracod species Danielopolina bahamensis, a calanoid copepod and a macellicephalan polynoid polychaete (perhaps a young Pelagomecellicephala iliffei). Stomach contents show anywhere from amber-colored fragments of an unidentified organism to brown unrecognized organic particles.
Life History: Only four specimens were collected. The holotype is a juvenile (A-1) male while the remaining three were A-3 juveniles (sex unknown). Copulatory organs were not present in the specimens.
Evolutionary Origins: The evolutionary origins of troglobitic ostracods remain undetermined. They may have originated from the deep sea (Iliffe 1990:95; 1991:227-228) or from shallow water crevices (Danielopol, 1990:141; Danielopol et al., 1996:82). These ostracods may have been in shallow anchialine pools and then migrated to the more stable cave environment (Iliffe in Kornicker & Iliffe, 1998:2). The genera Deeveya Kornicker & Iliffe, 1985 and Spelaeoecia Angel & Iliffe, 1987 comprise the subfamily Deeveyinae Kornicker & Iliffe, 1985. The distribution of this subfamily is restricted to the Caribbean, West Indies, Bermuda, and the Yucatan Peninsula.
Conservation Status: Restricted to a single cave on Eleuthera Island, Bahamas.
