Filellum cf. magnificum Peña Cantero, Svoboda & Vervoort, 2004 (Fig. 6g) Material examined. ANT XV/3: 48-150, some hydrothecae, on E. scotti; 48-220, some hydrothecae, on Sy. exochus; 48-276, several hydrothecae, on Sc. nana; ANT XXI/2: PS65/166, numerous hydrothecae, on O. erratum; PS65/274, numerous hydrothecae, on Staurotheca nonscripta Peña Cantero, Svoboda & Vervoort, 1997. Remarks. In spite of the absence of coppinia, the size of the hydrotheca and the size of the nematocysts perfectly agree with previous reports (Peña Cantero 2010, Peña Cantero et al. 2004, Soto Àngel & Peña Cantero 2015). However, in agreement with Peña Cantero et al. (1998), the identification of infertile material of Filellum is tentative. Cnidome consisting of large microbasic mastigophores [range 17.5–19.0 x 4.5–6.0 µm, mean 18.1±0.6 x 5.4±0.8 µm (n=4)] and small microbasic euryteles [range 6.0–7.5 x 2.5–3.5 µm, mean 6.9±0.4 x 2.8±0.3 µm (n=13)].
