| Summary: | Stegopoma plicatile (M. Sars, 1863) (Fig. 4G–H) Stegopoma plicatile —Schuchert, 2001: 51–53, fig. 37A–E (synonymy). Material examined. 9752#1, several stems up to 60 mm high, on axis of dead gorgonian, basibiont of Zygophylax, no gonothecae; Stn CE14011-BIO 217, a fragmented colony (longest fragment, 105 mm long), no gonothecae. Measurements (in µm). Hydrotheca: diameter at aperture 240–300, abcauline length 950, free part of adcauline length 50, adnate part of adcauline length 1000, adcauline length 1080, height, to the end of cusps 1200. Remarks. This species is easily recognizable by the simultaneous presence of adnate and free hydrothecae. The adnate ones (Fig. 4G), alternately arranged in one plane, are tubiform, with the apical portion curved outwards. The free hydrothecae (Fig. 4H) are on short pedicels that originate on the opposite side of each adnate hydrotheca, by the middle of the adcauline wall.
