Aplidium pannosum (Ritter, 1899)

(Figure 5C)

Material examined. Matua Island, Point Kluv, 14 m, three colonies (#403, 404, 419).

Remarks. The species was reported from this locality and described in details in our previous paper (Sanamyan & Sanamyan, 2017). The cloacal systems, as it was revealed on newly obtained photographs, vary from more or less round to somewhat more complex, with short cloacal canals converging to common cloacal openings (Figure 5C).
