See Schuchert (2001 b) for a complete synonymy.

Material examined. HCUS-S 0 40 (Hydrozoa Collection, University of Salento—fauna of the Salento Peninsula).

Description (based on our own observations; Brinckmann-Voss 1970; Schuchert 2001 b, 2010, 2012):

Hydroid. Hydrorhiza stolonal; colonies mostly stolonal, occasionally sparingly branched with 2 hydranths, rarely with up to 5 side branches, up to 2 cm in height; perisarc not thick, feebly annulated to smooth, frequently 2–3 annulations separated by smooth intervals; hydranths with 15–21 capitate tentacles either scattered or in 4–5 whorls, below them a whorl of 2–6 short filiform tentacles, which are often absent, but always present in regenerating hydranths. Gonophores as fixed sporosacs spherical, borne in 2 whorls in upper axil of tentacles in middle of hydranth body, without radial or circular canals, females with numerous eggs. Colours: colourless to reddish-rose.

Cnidome. Stenoteles of two size classes.

Habitat type. Shaded places in caves and also on rocks (depth range: 0–40 m) ( Brinckmann-Voss 1970; Boero & Fresi 1986; Schuchert 2001 b).

Substrate. On several substrates and organisms such as Peyssonnelia  sp., Balanus  shells, leaves and roots of Posidonia  beds, Myriapora truncata  .

Seasonality. March –May ( Brinckmann-Voss 1970) in the Tyrrhenian Sea; November ( Boero & Fresi 1986) in the Ligurian Sea; from February to March, and October in Salento waters (Gravili 2006; Gravili et al. 2008 a).

Reproductive period. In the Tyrrhenian Sea, fertile colonies occur from March to May ( Brinckmann-Voss 1970).

Distribution. Mediterranean ( Gravili et al. 2008 a), coasts of Brittany ( France), and Scotland (see Schuchert 2001 b).

Records in Salento. Rare at Otranto (Gravili 2006; Gravili et al. 2008 a).

Remarks. The filiform tentacles are usually missing in colonies from agitated waters ( Brinckmann-Voss 1970; Edwards & Harvey 1983). The Mediterranean records of this species are also discussed in the remarks on Coryne pusilla  (for more details see Schuchert 2005 a, 2010).
