On the genus Typhlocypris Vejdovsky, 1882 (Crustacea: Ostracoda: Candoninae), with description of two new species

In the present paper the genus Typhlocypris Vejdovsky?, 1882 is divided into two subgenera: Typhlocypris Vejdovsky?, 1882 and Pseudocandona Kaufmann, 1900. This division is made on the following characteristics: the morphology of the male antenna; the number of setae in the group on the second segment of the mandibular palp; and the morphology of the third thoracopod. The nominate subgenus is further divided into the following four species-groups: eremita, caribbeana, rostrata and prespica. The former zschokkei-group is incorporated into the eremita-group, which now has a total of ten Recent species and includes Typhlocypris (T.) pescei sp. nov. and T. (T.) skadari sp. nov., both described in the present paper. The new species were collected in subterranean waters of Greece and Montenegro respectively. Typhlocypris (T.) illiesi (McKenzie, 1971) is assigned to the eremita-group and some additional description of this species is provided following examination of its type material. Pseudocandona serbani Danielopol, 1978 and Candona szoecsi Farkas, 1958 are synonymized with Typhlocypris (T.) eremita, the first one after rechecking its type material and the second one after finding a great variability in some populations. Fourteen species are added to the caribbeana-group, which now includes 18 Recent species. One of its representatives, Typhlocypris (T.) cf. geratsi (Broodbakker, 1983), is recorded for the first time in Australia and a detailed description of the female is given. Typhlocypris (T.) marimotoi (McKenzie, 1972) is assigned to the rostrata-group and some additional details of its morphology are given here after rechecking its type material. The rostrata-group now has six Recent species. Typhlocypris (T.) prespica (Petkovski, 1959) remains the only representative of the prespica-group. The subgenus Pseudocandona has six Recent species, all previously belonging to the compressa-group. Males of T. (Pseudocandona) albicans (Brady, 1864), only rarely recorded by previous authors, were collected in Greece and are described in this paper. The same species is reported from Australia and Candona inexpecta Chapman, 1963, described from New Zealand, is synonymized with T. (P.) albicans after rechecking its type material. The present paper further contains a key to the subgenus Pseudocandona and all, except caribbeana, groups of the nominal genus. The taxonomy and zoogeography of the genus and its relation to the other Candoninae genera are also discussed. © The Natural History Museum.
