ON SOME RECENT NON-MARINE OSTRACODS FROM NORTHERN CHINA, WITH DESCRIPTION OF ONE NEW SPECIES

Preliminary investigations of urban waters in Beijing City and small water-bodies in Inner Mongolia yielded a total of 12 living ostracod species. Five species are new records for China: Candona quasiakaina Karanovic & Lee, 2012, Fabaeformiscandona myllaina Smith & Kamiya, 2007, Heterocypris auricularis sp. nov. (previously known as Heterocypris sanukiensis Okubo, 2004 nomen nudum), Ilyocypris mongolica Martens, 1991 and Plesiocypridopsis newtoni (Brady & Robertson, 1870). Bradleycypris vittata (Sass, 1903), Ilyocypris angulata Sars, 1903, Limnocythere stationis Vavra, 1891 and Physocypria kraepelini G. W. Muller, 1903 are the first records for Palaearctic China. Cypridopsis vidua (O. F. Muller, 1776), Heterocypris incongruens (Ramdohr, 1808) and Limnocythere inopinata (Baird, 1843) are also reported in this paper, although they had already been found in China before. Of the above species, B. vittata, I. angulata and I. mongolica are re-described. The present study expands our knowledge on the taxonomy and geographical distribution of ostracod species.
