| Abstract |
The Recent and Fossil species of Paralimnocythere are reassessed and the genus is characterized using both soft part and valve morphology. Seventeen species, of which eleven have living representatives, are here retained. Relictocytherina Negadaev-Nikonov, 1968 is confirmed as a synonym of Paralimnocythere; R. orginalis (Negadaev-Nikonov, 1965), the type species is furthermore synonymous with P. relicta (Lilljeborg, 1863). Paralimnocythere psammmophila (Flössner, 1965) and P. compressa (Brady & Norman, 1889) are both reinstated as valid species, quite different from P. relicta. All Recent Balkan species are retained as valid and P. ochridense (Klie, 1934) is here re-described as an example of the Balkan endemics. Paralimnocythere messanai nov. spec. is described from interstitial habitats in an Italian river and as such constitutes the first subterranean representative of the genus. There are seven Fossil species, the oldest ones being found in Miocene deposits. Paralimnocythere Wang Wen-Sheng, 1989 is a junior homonym and the three Cytherissa-like species require a new generic name. A new genus, Kiwicythere nov. gen., is erected to comprise a new species from the Chatham Islands (K. anneari nov. spec.) and P. vulgaris McKenzie & Swanson, 1981 from New Zealand. It is here postulated that this genus does not belong to the same phyletic lineage as Paralimnocythere s.s.; it is more closely related to other southern hemisphere limnocytherids. Paralimnocythere s.s. itself has a Palaeartic distribution. |
