| Diagnosis | Five stolonal hydrothecae creeping on stem of an antipatharian. Colony entangled with remnants of an unidentifiable anthoathecate hydroid. Hydrorhizal stolon smooth, thin. The unsegmented hydrothecal pedicel is very short, smooth, curved, passing upwards to diaphragm. Hydrothecae tubular, very large, slightly asymmetrical or symmetrical, adcauline side convex to above diaphragm, walls smooth to margin. Diaphragm varies from a membranous to a thin perisarcal ring. Margin circular, slightly everted, one hydrotheca with two widely separated marginal replications. |
