| Abstract |
Pleurobrachia Fleming, 1822 is the native taxon of ctenophores in the Black Sea. Until now, its species affiliation has not been resolved: the Black Sea Pleurobrachia is referred to either P. pileus (O.F. Müller, 1776) or P. rhodopis (Chun, 1879). In the taxonomic reviews, both species are recognised as occurring in the Black Sea. The experts on zooplankton identified the Black Sea Pleurobrachia based solely on its definitive body size, but size cannot be a sufficient diagnostic feature. To clarify the species identity of the Black Sea Pleurobrachia, we carried out a phylogenetic analysis using the nucleotide sequences of the mitochondrial COI and the nuclear 18S rRNA gene fragments. As a result, we have established that the Black Sea Pleurobrachia is P. pileus and its identification as P. rhodopis in the global taxonomic databases is erroneous. |
