The present study was carried out to examine unidentified and identified specimens of Nybelinia, Heteronybelinia, Mixonybelinia and Kotorella deposited at the Muséum national d’Histoire naturelle, Paris. A total of 17 different species including type specimens was found: Nybelinia africana Dollfus, 1960; N. erythraea Dollfus, 1960; N. goreensis Dollfus, 1960; N. lingualis (Cuvier, 1817); Nybelinia cf. lingualis (Cuvier, 1817); N. riseri Dollfus, 1960; N. scoliodoni (Vijayalakshmi, Vijayalakshmi & Gangadharam, 1996); N. strongyla Dollfus, 1960; N. surmenicola Okada, 1929; N. thyrsites Korotaeva, 1971; Heteronybelinia estigmena (Dollfus, 1960); H. eureia (Dollfus, 1960); H. minima Palm, 1999; H. nipponica (Yamaguti, 1952); H. robusta (Dollfus, 1960); H. yamagutii (Dollfus, 1960); Mixonybelinia edwinlintoni (Dollfus, 1960) n. comb.; Kotorella pronosoma (Stossich, 1901). M. edwinlintoni is redescribed. Nybelinia oodes Dollfus, 1960, H. alloiotica (Dollfus, 1960), H. cadenati (Dollfus, 1960), and H. senegalensis (Dollfus, 1960) are considered synonymous with H. estigmena (Dollfus, 1960). H. punctatissima (Dollfus, 1960) is considered synonymous with Nybelinia lingualis, and specimens of H. punctatissima as described in Dollfus (1960) are considered synonymous with H. estigmena. H. rougetcampanae (Dollfus, 1960) is considered synonymous with H. nipponica, and N. rhynchobatus Yang, Lin, Liu & Peng 1995 synonymous with Kotorella pronosoma. Five new localities and 12 new host records were established. The adults of Mixonybelinia edwinlintoni n. comb. and N. strongyla are reported for the first time. A high degree of morphological variability within the same species was observed, with postlarvae having the potential to reach a larger size than adults. Most of the studied species exhibit a wide host range and distribution. List of valid species are given for the five genera within the family Tentaculariidae: Nybelinia (24 species), Heteronybelinia (10), Mixonybelinia (3), Kotorella (1), and Tentacularia (1).
