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) Author Angel, Martin V. text Zootaxa 2013 2013-09-09 3709 5 401 431 journal article 43082 10.11646/zootaxa.3709.5.1 709296cc-ba34-450c-a90b-eefe0c54e5cf 1175-5326 222440 43F153E2-B0C0-4F05-A126-CB061877AFB6

TABLE 2. Comparison of meristic characters of male and female Chavturia abyssopelagica n. sp., Halocypris parvirostrata Chavtur & Stovbun, 2008, H. profunda n. sp. and H. striata (Müller, 1906). Characters that distinguish C. abyssopelagica from the Halocypretta species are italicised, and those that in combination distinguish between the three Halocypretta species are emboldened.
