Polycopidae Sars, 1866 ostracods from the DIVA II expedition of the RV “Meteor” at the Cape, Angola, and Guinea basins are presented here. They were collected between 26 February and 30 March 2005, from depths between 5,047 and 5,150 m. Metapolycope divae sp. nov. belongs to the subfamily Polycopsisinae Chavtur, 1983, and stands apart from the other(More)
Ostracods are drastically reduced crustaceans, with never more than eight appendages enclosed between two valves, leaving only a limited number of morphological characters for species delineation. Conservative morphology of characters used to define genera, along with high variability of characters used to define species are creating problems in applying a(More)
Previous studies have suggested incongruence between current systematics and molecular phylogenies of Sarsielloidea, with a possible polyphyly of the family Philomedidae. Here, we provide molecular phylogenetic analyses based on 18S rDNA and 28S rDNA. The former includes five new sequences and 12 from the GenBank, and the latter two new and six sequences(More)
Two new Thaumatoconcha Kornicker and Sohn, 1976a species, T. dandani n. sp. and T. quasiporosa n. sp., have been described in the present paper. Both species have been collected during two expeditions to the Southern Ocean and are found in the deep sea. The first species is most closely related to T. caraionae Kornicker and Sohn, 1976a, but it has a very(More)
Austromesocypris bluffensissp. n. is described and we report another species, Austromesocypris sp., both collected from subterranean aquatic habitats in Tasmania. This discovery adds a major taxonomic group to the already diverse invertebrate cave fauna of Tasmania, and is of interest because, globally, obligate subterranean aquatic species (stygobites) are(More)
