Rosalie F. Maddocks and Thomas M. Iliffe. 1991. Anchialine podocopid
Ostracoda of the Galapagos Islands. Zoological Journal of the Linnean Society, 103:75-99.
Water-filled fissures and lava tubes on Isla Santa Cruz and
Isla Isabela provide anchialine habitats for 11 species of podocopid and
platycopid Ostracoda, most with Atlantic and West Indian affinities. Their
ancestors may have been carried to earlier islands in the Galapagos system by
trans-Isthmian currents, on vegetation or larger animals, or by migrating
waterfowl. None are derived from present-day Pacific coastal faunas of
North, Central or South America. Two species of Cytheracea, a new species
of Anchistrocheles (Bairdiacea), and one of Cytherella (Platycopida)
are described.
