The monogenean Neobenedenia girellae (Hargis, 1955) Yamaguti, 1963 is redescribed and reported for the first time in Japan. The parasite was recovered from the body surface, fins, and occasionally from the eyes of 14 species, comprising 5 families of cultured marine fishes from several localities in southwestern Japan. Neobenedenia melleni (MacCallum, 1927) sensu Kaneko et al. (1988) from tilapia (Oreochromis mossambicus) in Hawaii is synonymized with this species. Examination of original specimens (syntypes) of N. melleni sensu MacCallum (1927) revealed differences with N. girellae in having a wide and rounded body, a prominently large anterior hamuli, and absence of glands of Goto. This Neobenedenia from Japanese fishes sometimes showed an unusual morphology of the individual parts of the median sclerites. The potential threat of N. girellae to the health of cultured Japanese fishes is indicated by its low host specificity, wide distribution, and ability to cause mortality due to heavy infection. Unregulated importation of amberjack fry (Seriola dumerili) to Japan appears to be the source of N. girellae infection in Japanese fishes since 1991.
单殖吸虫类的吉氏新贝尼登虫（Neobenedenia girellae）（哈吉斯，1955年）山口，1963年，在日本首次被重新描述并报道。该寄生虫是从日本西南部几个地方的14种养殖海水鱼体表、鳍部，偶尔也从眼部采集到的，这14种鱼分属于5个科。夏威夷罗非鱼（Oreochromis mossambicus）体内的梅氏新贝尼登虫（Neobenedenia melleni）（麦卡勒姆，1927年），按照金子等人（1988年）的定义，与该物种同义。对麦卡勒姆（1927年）定义的梅氏新贝尼登虫原始标本（合模标本）的检查显示，它与吉氏新贝尼登虫的区别在于身体宽阔且呈圆形、前钩明显较大，以及没有后藤腺。来自日本鱼类的这种新贝尼登虫有时在中硬片各部分呈现出异常形态。吉氏新贝尼登虫对日本养殖鱼类健康的潜在威胁体现在其宿主特异性低、分布广泛以及重度感染会导致死亡。自1991年以来，日本未加管控地进口黄尾鰤鱼苗（Seriola dumerili）似乎是日本鱼类感染吉氏新贝尼登虫的源头。
