Gender is feminine.</p> <p>Description</p> <p>Coral colonies are inter-connected with polyps by ribbon - like stolon expanding in irregular patterns on the surface of a dead coral (Fig. 2A), and budding of secondary polyps (Fig. 2C). The polyps arise from a ribbon - like stolon (0.6 mm in width).</p> <p>The holotype is about 19.7 mm tall and 0.2 mm in diameter, with eight polyps attached (Fig. 2D). Fully retracted polyps are up to 12 mm in height and 1.5 mm in width.</p> <p>Sclerites in the polyp (Fig. 3A,B,C) form a thick layer in the calyx wall region, being longitudinally arranged and tightly packed (Fig. 3D). The stolon is ribbon-shaped, with sclerites longitudinally arranged along the thin basal stolon (Fig. 3E). The sclerites in the tentacles and middle of the neck zone are transversely set (Fig. 4A, B,C).</p> <p>Tentacles sclerites are narrow and stellate plates; cross-like forms with slightly tubercular ornamentation; stellate plates (0.19– 0.06 mm long 0.08– 0.02 mm wide); cross-like sclerites (0.058 –0.082 mm long 0.047 –0.064 mm wide); smaller crosses, all of them with tubercular ornamentation (Fig. 5A).</p> <p>Pharyngeal sclerites are small warty plates (0.07–0.13 mm long, 0.010 –0.032 mm wide) (Fig. 5B).</p> <p>Neck zone sclerites are short, blunt rods, crosses with tubercular ornamentation; 0.16– 0.07 mm in length, 0.05– 0.01 mm wide; some crosses (Fig. 6A).</p> <p>I ntrusion sclerites are irregular-shaped, branched rods with tubercular ornamentation (0.14–0.52 mm long, 0.03–0.11 mm wide) (Fig. 6B).</p> <p>Calyx wall sclerites are irregular-shaped; crosses with dense tubercular ornamentation (0.45– 0.15 mm long 0.37– 0.06 mm wide); frequently with cross-like prominences (Fig.7A).</p> <p>Stolon sclerites are smooth to slightly warty plate,crosses; irregular-shaped with slightly tubercular ornamentation (0.40– 0.19 mm long 0.42– 0.02 mm wide); less cross-shaped forms (0.12– 0.25 mm long) (Fig. 7B).</p> <p>Remarks. The sclerome found in Telestula ridgensis sp. nov. is unique among the north-eastern Atlantic congeners having longitudinal rows of small warty rods and cross-like forms that extend from the distal end of the calyx towards the base of the tentacles. The sclerites of the new species from the neck zone, intrusion tissue, calyx wall, and ribbon-like stolon are notably different among the genus Telestula with an evident abundance of warty, irregular, and cylinder-like forms of small flattened ovals. Telestula ridgensis sp. nov. is morphologically closely related to Telestula septentrionalis, T. cf. batoni, and T. cf. spiculicula. According to Tixier-Durivault (1964) species, T. tubaria has eight chevrons of small sclerites in the neck region and eight longitudinal ridges of sclerites in a calyx wall. However, T. versluysi has densely tuberculate rounded spindles from the calyx wall and irregular spindles from the stolon (Weinberg 1990). T. mosaica has some arrowhead-like sclerites. The sclerites of T. kuekenthali have loose polyps, plump, coarsely tuberculate spindles from the calyx wall, irregular spindles, and cross-shaped sclerites from the top of the polyp (Weinberg 1990). Telestula stocki has plates on top of tentacles, sparse long spindles, warty spindles with complex tubercles, rods from stolon, and plump (Weinberg 1990).</p> </div>	https://treatment.plazi.org/id/039D87B2F359FFB24586FE41FBD69C40	Public Domain	No known copyright restrictions apply.
