Abstract
This brief report deals with the finding of Chrysodidymus Prowse, a new genus of chrysophytes for the Ukrainian algal flora, which has been found on the territory of “Dermansko-Ostrozkyi” National Nature Park (Rivne Region, Ukraine). Chrysodidymus synuroideus Prowse was revealed by means of SEM. The paper is illustrated by the original micrographs. The genus Chrysodidymus Prowse was described from the acid swamps in Malaysia in 1962 and since then it was found in many places on the Earth. Nevertheless the records of Ch. synuroideus are very restricted in Europe. We analyzed published micrographs of the scales of Ch. synuroideus and revealed that genus consists of two rather than one species, one of which is distributed in the temperate zone and the second one is restricted to tropics and subtropics. For the further revision of the genus Chrysodidymus it should be typified.
Keywords: chrysophytes, Synurales, scales, typification
