On the recent Cyclocypridinae (Podocopida, Candonidae) with description of two new genera and one new species


Karanovic, I, On the recent Cyclocypridinae (Podocopida, Candonidae) with description of two new genera and one new species, Zootaxa, 2820 pp. 1-61. ISSN 1175-5326 (2011) [Contribution to Refereed Journal]


The recent representatives of the subfamily Cyclocypridinae Kaufmann, 1900 are revised here, based on some newly collected Australian material, as well as an extensive study of type material of already described species deposited in various museums. The following two new genera are proposed: Kempfcyclocypris gen. nov. and Keysercypria gen. nov. The genus Kempfcyclocypris is erected to include single new species from subterranean waters of New South Wales, Australia. Kempfcyclocypris australis gen. et sp. nov. can be distinguished from other members of the subfamily by the following characters: 6-segmented antennula, absence of the sexual bristles on antenna, weakly asymmetrical prehensile palps, absence of the basal seta on the second thoracopod, and the long distal seta on the penultimate segment of the third thoracopod. Keysercypria is erected to include some South American species previously described in the genera Physocypria Vávra, 1897 or Cypria Zenker, 1854. The main characters of this genus are: rather globular carapace, with or without marginal tubercles; very short setae on endopodal segments of the third thoracopod; unequally long setae "h1" and "h2" on the terminal segment of the same appendage; and the presence of the basal seta on the second thoracopod. Keysercypria affinis (Klie, 1933) comb. nov. is chosen as the type species and, together with K. deformis (Klie, 1940) comb. nov., K. longiseta (Klie, 1930) comb. nov., K. obtusa (Klie, 1940) comb. nov., and K. pellucida (Sars, 1901), redescribed in the present paper and lectotype and paralectotype are designated. After examining and redescribing the type species of the genus Physocypria Vávra, 1897, P. bullata Vávra, 1897, the genus Mecynocypria Rome, 1962 is synonymised with Physocypria. Lectotype of P. bullata is here designated. For each valid genus a diagnosis, a key to species and a distribution map are provided. A list of six genera and 87 species, currently belonging to the subfamily Cyclocypridinae, is given at the end of the paper, along with their synonyms. Twenty four species are not included in the keys due to lack of data; these are also listed at the end of the paper.
