Краткое описание морфология
Umbrella transparent and yellowish, disc-shaped, 9.5 cm in diameter, flattened, smooth, with thin but firm mesoglea. Stomach circular, very large, 7.7 cm in diameter including stomach pouches, mouth circular with no pronounced lips; stomach wall thin, yellowish and slightly opaque. Stomach pouches 31, interradial, irregular in shape ranging from rectangular to square, each one with a prominent globular gelatinous protuberance of the umbrellar mesoglea contained within the distal half, giving the general appearance of a rosary chain within the circumference of the umbrella. Each mesogleal protuberance is completely laterally contained within each stomach pouch cavity, without attachments to the lateral walls, and extends into the subumbrella, almost but not completely blocking the distal-most portion of the stomach pouch. Marginal lappets 31 to 32, interradial, larger than stomach pouches, mostly rectangular in shape but a few slightly trapezoidal (minor base centripetal), with distal corners rounded. Peripheral canal system present. Canals uniformally wide, usually wider than the central part of each lappet, and extending vertically along both sides of each peronia. Otoporpae absent. Tentacles 31 (plus one partially developed tentacle base), about 4 to 5 cm in length, rising from roots of variable length embedded between the distal portions of stomach pouches. Peronia 32, fusiform, simple, of irregular length, without cnidocysts, tapering out distally. Gonads not observed. Velum complete, very thin, 0.2 cm wide.
