Three new species of
Scolelepis were present in the Russian collections from the Arctic Ocean and the border areas:
S. matsugae,
S. burkovskii and
S. korsuni. All these are from the Barents Sea.
S. korsuni is known also from the northern part of the North Sea, and
S. matsugae from the Kara Sea and Franz-Joseph Land. There are no other species of
Scolelepis in the Russian arctic zoological collections. The diagnostic characters for
S. korsuni are: presence of superior flag-like process in middle dorsal lamellae, absence of setae in first notopodia, shape of hooks and their number; for
S. matsugae: shape of prostomium, shape of hooks, setiger of hooks starting and pattern of branchiae decreasing.
S. burkovskii is separated by a complex of characters. Five species with
S. squamatus (O.F. Müller, 1806) and
S. foliosus (Audouin & Milne Edwards, 1833) are now known from the Arctic Ocean and the border areas.
