Reference specimens deposited. MZUSP 978, 1 specimen. MZUSP 1485, 1 specimen. World distribution. Southwest of India, North Atlantic, including several locations in Europe (Cornelius 1995; Bouillon 1999), Argentina (Goy 1979) and Brazil (Tronolone 2001, this study). Distribution in Brazil. From the state of São Paulo to Santa Catarina (Tronolone 2001; Nogueira 2012; this study). Description. Nearly hemispherical umbrella, 1–15 mm in diameter, and 4–12 mm in height. Manubrium quadrate and short, about 1 / 3 of the height of umbrella cavity, cruciform shape in aboral view, without peduncle; four black spots on the interradial walls of the manubrium (Fig. 18), which occasionally may be absent in fixed material. Wide mouth with four perradial wide lips, with slightly fringed edges (Fig. 18). Four radial canals. Gonads linear–ovate in young individuals, growing laterally over the distal 2 / 3 of the canals, not reaching the circular canal. Long hollow tentacles, with conical bulbs, usually 16, and rarely more (up to 24). A pair of coiled cirri flanking each tentacle. 1–3 rudimentary bulbs between each tentacle, which may develop tentacles, possibly with lateral cirri. 8 adradial closed-statocysts. Systematic remarks. Although the specimens studied had rather shrunk cirri because of fixation, these can be observed under higher magnification (Fig. 17), a characteristic that, together with 1–3 rudimentary bulbs with cirri between each tentacle; 8 adradial statocysts; and four interradial black spots on the manubrium ...
