Planktonic ostracods (Myodocopa: Halocyprididae) from abyssopelagic depths in the Atlantic, North Pacific and Gulf of Oman: Chavturia abyssopelagica (n. gen., n. sp.), Halocypretta profunda (n. sp.), Halocypretta parvirostrata Chavtur and Stovbun, 2008 and Halocypretta striata (Müller, 1906)
No full textA novel species and genus of halocyprid ostracod, Chavturia abyssopelagica, and a new species of Halocypretta are described from depths >3000 m in the Atlantic. The new genus is related to Halocypretta, itself a genus that has only recently been described from deep waters in the North Pacific. Supplementary observations are made on the type species, Halocypretta parvirostrata, based on additional specimens from the North Pacific. Halocypretta striata from the Gulf of Oman is reported for the first time since it was first described and is redescribed in detail. All four species are illustrated and compared using a set of meristic characters
Scottoecia—a new genus of halocyprid ostracod, with the description of Scottoecia arabica nov. sp. and the redescription of Bathyconchoecia darcythompsoni (Scott, 1909)
No full textOn re-describing two species originally attributed to the halocyprid genus Bathyconchoecia (B. darcythompsoni Scott, 1909 from the North Atlantic and B. lacunosa sensu James 1973 from the Gulf of Oman) they were found to show substantive differences from the type species for the genus, B. paulula. These differences are: 1. Several carapace characteristics including size, the structure of the rostra and incisure, and the locations of the openings of the carapace glands.2. Limb structures notably of the mandibles.3. The exceptionally long dorsal terminal seta on the male sixth limb.4. The structure of the copulatory appendage. These two species are placed in a newly defined genus Scottoecia, for which S. arabica is designated as the type species. The original descriptions of three other Bathyconchoecia species, show that they belong to Scottoecia, namely S. crosnieri (Poulsen, 1969a), S. subrufa (Angel, 1970a) and S. foveolata (Deevey, 1968). This has been confirmed for the first two species by the examination of the type material. Another species Bathyconchoecia baskiae Poulsen, (1969b) has similar mandibles, and is probably closely related, but does not share all the characteristics of the new genus.The validity of the previous classification in which Bathyconchoecia is included in the subfamily, the Euconchoecinae, is questioned
Bathyconchoeciinae, a new subfamily of deep oceanic planktonic halocyprid Ostracod (Myodocopa, Ostracoda)
No full textSpecies of the genera Bathyconchoecia and Scottoecia are currently classified in the subfamily Euconchoeciinae together with species of the genus Euconchoecia. The morphological and ecological characteristics of many of the species currently attributable to these two taxa are compared with a range of Euconchoecia species and are shown to differ extensively. These differences are sufficient to separate these taxa at the subfamily level. Therefore, a new subfamily, the Bathyconchoeciinae is proposed to accommodate all the species currently classified in the genera Bathyconchoecia and Scottoecia

Towards a full inventory of planktonic Ostracoda (Crustacea) for the subtropical Northwestern Atlantic Ocean
No full text92 species of planktonic ostracods were identified from five total water column samples of macroplankton collected from the surface to depths of 5000 m in the northwest subtropical Atlantic. Thirteen of these species are either totally novel or previously undescribed. This brings the total inventory of planktonic ostracods known from this region to118 species, and for the whole Atlantic to 153. All but one of the undescribed species were collected from depths >1000 m. This region is already the most comprehensively studied in the global ocean for plankonic ostracods. Similar studies conducted in other less well studied regions particularly in the Pacific and Indian Oceans will reveal far higher numbers of novel species
