Abstract: Groups of spines forming the coxal ornamentation of the fourth pair of swimming legs and some other morphological details are used to distinguish species of the genus Cyclops O. F. Müller, 1776, from several habitats in the Czech Republic. The identity of populations based on these characters agrees with that derived from allozyme analyses. Besides the easily distinguished species Cyclops vicinus Uljanin, 1857 and C. insignis Claus, 1857, three other species were found: C. furcifer Claus, 1857 (in temporary waters) and probably C. strenuus Fischer, 1851 and C. abyssorum G. O. Sars, 1863 (in permanent waters). |
