Freshwater fishes (25 identified and 5 unidentified species) were caught in rivers in Wakayama Prefecture (Kinki), and Tokushima and Kochi Prefectures (Shikoku), Japan, in 1998, 1999, and 2000 and examined fresh for adult digeneans (Trematoda). Digeneans of nine species were found, mainly in the digestive tract. Eight of them were identified as previously known species, and one remained unidentified. A single specimen of the latter, Allocreadium sp., was found in Zacco temminckii (Temminck and Schlegel) (Cyprinidae) (Japanese name kawamutsu) from the Kaifu River in Kaiyo, Tokushima Prefecture. It probably represents an undescribed species. The digeneans are described and figured. Their final fish hosts, geographical distributions, and life cycles, where known in Japan, are discussed.
