Diatoms of the genus Skeletonema were found in bottle samples of phytoplankton collected in Paris Bay (Bosfor Vostochnyi Strait, the Sea of Japan) in June-December 2013 at a water temperature of -1.8 to 21.6°C and a salinity of 25.4-33.2‰. Using electron microscopy, we identified the predominant species of autumn phytoplankton bloom as S. marinoi Sarno et Zingone. This is the first find of the species in the marine waters of Russia. The morphology of S. marinoi is described; further data on its ecology and distribution are provided.

Key words: marine phytoplankton, diatoms, Skeletonema marinoi, morphology, distribution.
