Staurotheca dichotoma Allman, 1888 (Fig. 10 C) Staurotheca dichotoma— Totton, 1930: 178, fig. 27a, c, pl. 2 fig. 9; Peña Cantero & Vervoort, 2003: 2681 –2683, fig. 7 (synonymy); Peña Cantero & Gili, 2006: 768; Peña Cantero, 2010b: 769; 2012: 859; Soto Àngel & Peña Cantero, 2015: 998, fig. 8d–e. Material examined. Stn 8, fragment 15 mm long (MNCN 2.03/558); Stn 140, mass of stems ca. 60 mm in diameter, basibiont of Hebella plana (NIWA 117530). Remarks. In the material examined the hydrothecae are arranged in decussate pairs and have a significant free portion (about 200 µm). This is a species characterized by having quite robust hydrothecae (Fig. 10 C) with a relatively large diameter at the hydrothecal aperture (300–320 µm in the present material). The larger microbasic mastigophores are 19–22 x 4–4.5 µm. Ecology and distribution. Reviewed by Peña Cantero & Vervoort (2003). Found at depths from 82 (Totton 1930) to 799 m (Peña Cantero et al. 1997a); present material from 231 to 541 m, ... : Published as part of ÁLVARO L.
