Moser, 1925
Nectophores with large thrust block and axial wings that are extensive laterally but not axially. Highly looped lateral radial canals on nectosac, whose adaxial wall lacks musculature. Dorsal radial canal with several pronounced bends; ventral canal straight. Thickened, dorsally convex bracts, somewhat triangular in shape, with irregular teeth on the broad distal end. Canal ends some distance from distal extremity. Tentilla with diverticular canal.
