ABSTRACT. The fauna of polychaetes of the Black Sea has been studied in detail, but species of the Scalibregmatidae family have never been indicated in literature to date. Scalibregmatids are wide spread in the World Ocean, but they are rarely found in benthic collections. In 2017, in one of the bays of Sevastopol (Crimea), a member of Scalibregmatidae, Hyboscolex sp., was first identified. The sediment at the collection site is medium-grained sand of crushed mollusk shells with a small admixture of crushed limestone. The depth was 15m. The temperature of water was 19.3°C and the salinity was 17.7‰. The article presents morphological characteristics and photographs of alive and fixed in 4% formaldehyde specimen. Species affiliation Hyboscolex sp. which was found in the Black Sea is under discussion.
KEY WORDS: Polychaeta, Scalibregmatidae, Hyboscolex sp., the Black Sea.
