Sertularella johnstoni – Naumov & Stepanjants 1962: 82, fig. 6. Sertularella filiformis – Naumov & Stepanjants 1972: 40, fig. 36.

Ecology. Eurybathic species, found at depths between 3 and 750 m (Stepanjants 1979). On rocky, stony and sandy bottoms (Stepanjants 1979; Peña Cantero & García Carrascosa 1995). Basibiont of other hydroids (Vervoort 1972a; Stepanjants 1979). Gonothecae: February, March and June (Vervoort 1972a), April (Millard 1977), September to June (Stepanjants 1979) and December (Blanco 1984).

Distribution. Uncertain, because of the presence of a group of closely related species (Vervoort 1972a). Sub-Antarctic waters: southern South-America (Kirchenpauer 1884; Jäderholm 1905; 1926; Hartlaub 1905; Blanco 1967b; Vervoort 1972a; Stepanjants 1979), Falkland Islands (Jäderholm 1905; Vervoort 1972a), Kerguélen and Crozet (Millard 1977; Stepanjants 1979), between Possession and Cochons (Millard 1977) and Lena Bank (Stepanjants 1979). Antarctic waters: South Shetland Islands (Stepanjants 1979; Peña Cantero & García Carrascosa 1995), South Orkney Islands (Stepanjants 1979), Low Island (Blanco 1984) and the Weddell Sea (Blanco 1967a).
