Two new and two known opecoelid trematodes are described from goatfishes (Mullidae) in Japan. Dactylostomum tanegashimense sp. n., found in the pyloric caeca and intestine of Upeneus bensasi (?) at Tanega-shima, is characterized by the acetabulum with two pairs of apertural and four pairs of peripheral papillae, and the anterior extent of vitellaria lying near the posterior border of acetabulum. D. longivesiculum sp. n., obtained from the pyloric caeca and intestine of Parupeneus indicus at Ishigaki-jima, is characterized by having the seminal vesicle longer and more winding, the acetabulum with two pairs of apertural and four pairs of peripheral papillae, and the vitellaria the anterior extremity of which reaches halfway between the ovary and the acetabulum. In addition to the above, some morphological and taxonomic notes are given on Paropecoelus elongatus (OZAKI, 1928) (syn. P. adelongatus (NAGATY, 1954)) and P. quadratus (OZAKI, 1928)comb. n.
