Abstract:
On the basis of measurements of morphological variation and appearance at different environmental conditions, and observations of different kinds of reproduction, the genus Chrysolykos Mack 1951 is revised. The genus Chrysoikos is included in Chrysolykos. Members of the genus are shown to be morphologically very plastic. Environmentally induced heterauxis may be found as well as changed lorica shape in rudimentary alternation of generations. The following species and varieties are accepted: C. skujae, C. angulatus and C. planctonicus with the var. planctonicus, var. recticollis, var. hamulatus and var. allabardiformis. C. calceatus and C. complanatus need further investigation. They may belong to other genera.
