Deeveya spiralis Kornicker & Iliffe, 1985
Taxonomic Characterization: Species has no rostrum, eight segments on the first antennae, a dorsal bristle-bearing process on the first expodial segment of the sixth limb, and three bristles on the seventh limb. The basal endite of the mandible of this species bears two stout lateral bristles that are twisted around each other. All furcal claws are separated from the lamellae by a suture. Carapaces appear reticulate in transmitted or reflected light, but reticulations mostly within translucent shell wall (Kornicker & Iliffe, 1985; Kornicker, Yager & Williams, 1990).
Disposition of Specimens: National Museum of Natural History, Smithsonian Institution, catalog numbers USNM 193117-8.
Ecological Classification: Stygobitic
Size: Adult females length range from 2.67 to 2.87 mm
Number of Species in Genus: Seven, all from anchialine caves
|Deeveya: genus range|
Species Range: Known only from The Hole, Providenciales Island, Turks and
Closest Related Species: D. styrax Kornicker, 1990 from Abaco and Grand Bahama
Habitat: Anchialine limestone caves
Ecology: Found free-swimming at a depth of 5-7 m. Specimens were collected below the halocline in fully marine salinity waters (35-36 ppt).
Life History: Adult females unextruded eggs vary in size within same specimen( Kornicker & Iliffe, 1985; Kornicker & Palmer, 1987). The genital tube is on its left side (Kornicker, Yager & Williams, 1990). Only two adult females have been collected.
Evolutionary Origins: The evolutionary origins of troglobitic ostracodes 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 ostracodes 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 Providenciales Island.
