Ovabunda hamsina (Reinicke 1997)

The holotype is 25 mm high and its stalk is 18 mm long, 15 mm wide at its base and 12 mm wide at its uppermost part. Polyp’s body reaches up to 2 mm long; tentacles 5 mm long featuring three rows of 1 mm long and 0.16 mm wide pinnules, 19-21 in the outermost row. An incomplete fourth row is occasionally present. The pinnules are separated by a two-pinnule width space. The sclerites are Ovabunda-type (Fig. 13a), 0.015–0.025 × 0.016–0.035 mm in diameter (n = 25). Occasionally, two sclerites are partially fused, reaching 0.034 mm in maximal diameter (Fig. 13b). The tentacles of the paratypes (RMNH Coel. 25902, 23533, 25906) bear three rows of pinnules on each side, with 19–22, 19–21 and 17–22 pinnules in the outermost row, respectively, and all feature Ovabunda-type sclerites. The original description indicated non-pulsating polyps in live colonies. The ethanol-preserved colony is light beige.
