Utevsky, Serge Y. (2009). A new marine fish leech species of the genus Oceanobdella (Clitellata, Piscicolidae) from coastal waters of Sakhalin Island. Acta Parasitologica. 54(4): 350-354.
A new species of marine fish leeches is described and compared with its congeners. Oceanobdella sakhalinica possesses
a unique combination of characters: the anterior sucker is small; one of posterior transverse bands on the urosome is very dark;
a wedge-shaped patch is located on the posterior sucker; posterior crop caeca are separate for their entire length; accessory
glands on the atrium are lacking; five pairs of testisacs are present; the copulatory area and the conductive tissue are lacking.
Hosts include a sculpin Myoxocephalus sp. and the blackline prickleback Acantholumpenus mackayi. The leeches were collected
in Aniva Bay, southern Sakhalin.
