Diagnosis Consistent 3:8 aspect ratio between the widest measure perpendicular to the oral-aboral axis and overall oral-aboral length. Aboral organ sunken approximately one-eighth of the total body length relative to the surrounding tissue. Comb rows extend along most of body length. The ctenes are ~ 3–4 mm long, and associated compound cilia are deep red in color. Paragastric canals with large lobate diverticulae. Tentacle sheaths perpendicular to the gut, approximately midway along the length of the animal’s body, opening into a large groove spanning ~ 30% of total body length along the aboral side. Large stomodaeum is roughly rectangular in the stomodaeal plane and flattened in the tentacular plane, appearing black in adult individuals. [details]
