Adelogorgiaphyllosclera Bayer, 1958.

Genus originally included in family Plexauridae (Bayer 1958). Presence of moderately thick coenenchyme; polyps communicate directly with system of longitudinal canals. Exterior coenenchyme contains derivatives of short, stout capstans called double wheels/discs; large, leaf-like expansions (on one side) up to 0.15 mm long; spindles with tubercles in transverse rows, to 0.2 mm, some developed as leaf clubs. Interior layers of coenenchyme contain only spindles. Anthocodiae weakly to moderately armed with flat rods, 0.15–0.3 mm long.

Adelo- is Greek for unknown. When Bayer described this genus in 1958 it was a new, unknown gorgonian genus; however, Bayer did not discuss the derivation.
