Material examined. HCUS-S 0 14 (Hydrozoa Collection, University of Salento—fauna of the Salento Peninsula)—medusa stage. Description (based on our own observations; Russell 1953 ; Brinckmann-Voss 1970 ; Schuchert, 2009): Hydroid. Unknown. Medusa. Umbrella nearly hemispherical, up to 1 mm wide and high, with thin lateral walls and thickened jelly at apex; manubrium attached to a broad and well-developed gastric peduncle, mouth lips containing each a group of about 100 cnidocysts; 4 narrow radial canals and a circular canal; gonads encircling the manubrium without radial interruptions on mature specimens; velum broad; 4 small marginal bulbs; 4 marginal tentacles, cnidocysts along the entire tentacle surface and in terminal swellings; without apparent ocelli; immature animals produce secondary medusae via medusae buds on middle region of manubrium; mature animals without buds. Colours: manubrium blackish brown, marginal bulbs with blackish pigment granules; brownish swellings on tentacles. Cnidome. Microbasic euryteles on tentacles, heteronemes (microbasic euryteles?) from lips, desmonemes on tentacles. Habitat type . The medusa can be found close to the water surface ( Brinckmann-Voss 1970 , 1987 ). Seasonality. July–August (own observations). Reproductive period. July–August, as mature medusae (own observations). Distribution. Atlantic, Indo-Pacific, Mediterranean ( Medel & López-González 1996 ; Schuchert 1996 , 2009; Bouillon & Barnett 1999 ; Bouillon et al . 2004; Genzano et al . 2008 ). Records in Salento. Rare at S.ta Caterina (Ionian Sea, Apulia). Remarks. A single medusa from a Salento plankton sample was examined in the present study. Gonad maturation and medusa budding depend on falling temperatures ( Brinckmann-Voss 1970 ). References.
