Gills.</p><p>Prevalence and intensity range (mean). 100% (2/2) and 1–2 (1.5) in the Tomio River, Nara Prefecture; 25% (1/4) and 1 in the Kitakata River, Tottori Prefecture; 40% (4/10) and 1–3 in Lake Kasumigaura, Ibaraki Prefecture .</p><p>Remarks. Dactylogyrus squameus was originally described by Gussev (1955) from the gills of Pseudorasbora parva from the Amur River and Lake Chanka, Far-East Russia, and subsequently reported from the same host in Heilongjiang, Liaoning, Hubei, and Yunnan, China (Ji et al. 1982; Chen 1984; Wu and Wang 1991; Liang 2000). The species was transferred to the genus Neodactylogyrus by Yamaguti (1963), although this genus had been synonymized with Dactylogyrus by Mizelle and Donahue (1944). The specimens examined in this study almost conform to the descriptions and illustrations of D. squameus by Gussev (1955, 1985), Bykhovskaya-Pavlovskaya et al. (1962), Wu and Wang (1991), Liang (2000), Ondračkova et al. (2004), and Gussev et al. (2010). The dorsal anchors of our specimens are slightly smaller than those authors’ measurements, but this may be due to intraspecific variation because the anchor’s shape and the male copulatory organs of our specimens agree with the cited descriptions. The present collection in Japan represents a new country record for Dactylogyrus squameus . This monogenean established populations infecting Pseudorasbora parva in Kazakhstan, Tajikistan, the Kyrgyz Republic, Ukraine, the Czech Republic, Slovak Republic, and Italy after both species were introduced from Far-East Asia into these countries (Gvozdev and Agapova 1977; Gussev 1985; Ondračkova et al. 2004; Galli et al. 2007). Ondračkova et al. (2004) listed the monogenean as occurring in “ Uzbekistan ” by reference to Gussev (1985), but this was most probably a mistranslation of “ Ukraine ”.</p><p>Japanese name. The new Japanese name is a combination of “motsugo” and “yubigata-mushi”, which are the Japanese names of P. parva and the genus Dactylogyrus (as “yubigata-mushi-zoku”), respectively.</p></div>	https://treatment.plazi.org/id/03E79E5BB5717A4FFEFEFEBFFDF1FC96	Public Domain	No known copyright restrictions apply.

Gills.</p><p>Prevalence and intensity range (mean). 90% (9/10) with no data for intensity in Lake Kasumigaura, Ibaraki Prefecture; seven worms infected one P . parva in the Senō River, Okayama Prefecture .</p><p>Remarks. Ancyrocephalus pseudorasborae was originally described by Achmerow (1952) from the gills of Pseudorasbora parva in Lake Bolon, Far-East Russia. It was subsequently reported from the same host in Heilongjiang, Liaoning, Shandong, Shanghai, Jiangxi, Hubei, Zhejiang and Yunnan, China (Anonymous 1973; Ji et al. 1982; Chen 1984; Wu 1991, 2000) and the Amur River, Russia (Gussev 1955, 1985; Bykhovskaya-Pavlovskaya et al. 1962; Gussev et al. 2010). The measurements of sclerotized structures examined in this study are slightly smaller than those reported by Gussev (1955, 1985), Bykhovskaya-Pavlovskaya et al. (1962), Anonymous (1973), Wu (1991, 2000), and Gussev et al. (2010), but the ranges of the measurements overlap, and all the descriptions of the male copulatory organ are in general agreement. The present collection represents the first record of Ancyrocephalus pseudorasborae in Japan.</p><p>Japanese names. The new Japanese generic name, “yotsume-ikari” (“zoku” means a genus), refers to the opisthohaptor with four anchors possessed by Ancyrocephalus spp. and means a grapnel anchor in Japanese. Part of the new Japanese name of the species is “motsugo”, which is the Japanese name of the host.</p><p>Genus Bivaginogyrus Gussev and Gerasev, 1985</p><p>[New Japanese name: Futa-ana-mushi-zoku]</p><p>Bivaginogyrus obscurus (Gussev, 1955)</p><p>[New Japanese name: Motsugo-futa-ana-mushi]</p><p>Host. Pseudorasbora parva ( Cypriniformes: Cyprinidae).</p><p>Site of infection. Gills.</p><p>Material examined. Two and three specimens collected from the Tomio River, Nara Prefecture (NSMT-Pl 6179), and the Senō River, Okayama Prefecture (NSMT-Pl 6182), respectively .</p><p>Prevalence and intensity. 50% (1/2) and 2 in the Tomio River, Nara Prefecture; four worms infected one P . parva in the Senō River, Okayama Prefecture .</p><p>Remarks. In Japan this monogenean was first described from Pseudorasbora parva and P. pumila Miyadi, 1930 in Lake Kasumigaura, Ibaraki Prefecture and in ponds of Shinonoi, Nagano Prefecture, respectively by Nitta and Nagasawa (2014). The specimens from Nara and Okayama prefectures correspond well with those from Lake Kasumigaura and ponds of Shinonoi. The present collections constitute new prefectural records and extend the geographical distribution of the species from Ibaraki and Nagano prefectures westward to Nara and Okayama prefectures.</p><p>Japanese names. The new Japanese generic name is a combination of “Futa-ana” and “mushi” which mean two holes (i.e., vaginae) and worms, respectively (“zoku” means a genus). Part of the new Japanese name of the species is “motsugo”, which is the Japanese name of the host.</p></div>	https://treatment.plazi.org/id/03E79E5BB5747A4EFF3CF890FD70FB50	Public Domain	No known copyright restrictions apply.
