 Location: gills
Host: Ctenopharyngodon idella
Dist: Luzon
Records: Albaladejo and Arthur 1989; Lumanlan et al. 1992
Remarks: Trichodina kupermani was reported from young grass carp originating from Taiwan and Hongkong which were examined in Quezon City. As fish from Taiwan were later stocked into Caliraya Lake, Laguna Province, this species is probably established in Philippine waters.
Shulman (1984) considered T kupermani a synonym of T. mutabilis Kazubski and Migala, 1968, however, we follow Albaladejo and Arthur (1989) in regarding it as distinct

Host: Cyprinus carpio carpio
Dist: Luzon
Records: Albaladejo and Arthur 1989; Lumanlan et al. 1992

Dist: Luzon
Records: 1. Albaladejo and Arthur 1989; 2. Lumanlan et al. 1992
Remarks: This parasite was found on juvenile Chinese carps imported from Hongkong, Taiwan and Indonesia and examined at Quezon City. As these fish were stocked into both aquaculture ponds and natural waters, it is probable that Trichodina nigra is now established in the Philippines.
 
Trichodina nobillis Chen, 1963(F)
 Location: gills, skin
Hosts:Aristichthys nobilis (1,2)

Records: 1. Duncan 1977; 2. Davy and Graham 1979 (-); 3. Natividad 1987 (-)
Remarks: As noted by Lom and Haldar (1977), this species is probably a synonym of Trichodinella epizootica (Raabe, 1950).
Lumanlan et al. (1992) considered T. carpi to have been introduced into the Philippines along with common carp.

Remarks: This parasite was found on juvenile Chinese carps imported from Hongkong, Taiwan, Thailand and Indonesia and from goldfish originating from Hongkong which were examined at Quezon City. As the Chinese carps were stocked into both aquaculture ponds and natural waters, it is probable that TRichodinella epizootica, if not already present, is now established in the country.

Dist: Luzon, Panay
Records: Bondad-Reantaso and Arthur 1989a (-), 1989b, 1990
Remarks: The synonymy follows Arthur (1995). Tripartiella spatula was erroneously listed as a junior synonym of T. clavodonta by Bondad-Reantaso and Arthur (1989b).
This species was introduced into the Philippines with the importation of tilapias (see Bondad-Reantaso and Arthur 1989b, 1990).

Bucephalus paraheterotentaculatus (M)
 Velasquez, 1959
Location: stomach, intestine
Host: Seriolina nigrofasciata
Dist.: Luzon
Record: Velasquez 1959
Remarks: Velasquez (1966, Table 1) in an apparent lapsus calami, listed Bucephalus heterotentaculatus as being described from Seriola nigrofasciata (syn. of Seriolina nigrofasciata) from the Philippines. As her Table 1 summarized new taxa established by Dr. Velasquez, this listing must pertain to B. paraheterotentaculatus and not to B. heterotentaculatus Bravo Hollis and Solgandares-Bernal, 1956, a species which has never been reported from the Philippines.

Bucephalus various Manter, 1940(M)
 Syn: Bucephalus pseudovaricus Velasquez, 1959
 Location: intestine
Host: Caranx sp.
Dist.: Luzon
Record: Velasquez 1959
Remarks: The synonymy follows Velasquez (1975a).
Velasquez (1959) also reported this species from the gills, however; this finding was probably the result of stomach eversion during host capture.

 Syn.: Bucephaloides philippinorum Velasquez, 1959
 Location: stomach
Host: Sphyraena langsar

Record: Velasquez 1959
Remarks: Srivastava and Chauhan (1973) synonymized the genus Bucephaloides Hopkins, 1954 with Prosorhynchoides Dollfus, 1929.
The finding of this species on the gills was probably the result of stomach eversion during host capture.

Prosorhynchoides sibi (Yamaguti, 1940) n. comb.(M)

Remarks: Specimens reported from the musculature and gills of Sparus berda (syn. of Acanthopagrus berda) by Velasquez (1959) were immature and thus most probably metacercariae.

Prosorhynchus crucibulum (Rudolphi, 1819)  Odhner, 1905(M)

 Location: base of gill arches
Host: Sphyraena sp.
Dist.: Luzon
Record: Velasquez 1970
Remarks: The listing of this parasite from Sphyraena langsar by Velasquez (1977a) is due to an error, several lines of her table having been omitted (compare Velasquez 1974 with 1977a).

Dist.: Luzon, Palawan
Records: 1. Fischthal and Kuntz 1964d (Palawan); 2. Velasquez 1975a (Luzon)
Remarks: In her monograph on the Digenea of Philippine fishes, Velasquez (1975a) listed Torticaecum nipponicum from “bagaong,” the tagalog common name given for Terapon jarbua in her host-parasite list; however, she did not list this parasite under this host species. Although not clearly indicated, her listing of this parasite from Eleotris fusca is considered to pertain only to the record Fischthal and Kuntz (1964d) from Palawan Island.

Although not clearly indicated, her listings of didymozoid larvae in Euthynnus yaito (syn. of E. affinis ) and Puntius binotatus are considered to pertain only to the report by Fischthal and Kuntz (1964d) from Palawan Island.

11 The reports of Albaladejo and Arthur (1989) and Lumanlan et al. (1992) pertain to common carp and grass carp imported from Indonesia, and Taiwan and Hongkong, respectively, which were stocked on Luzon Island.

12 This report involves a tentative parasite identification.

13 Material reported only as Trichodina in the abstract of Natividad et al. (1986a) was noted by Natividad et al. (1986b) to include T. acuta (subsequently referred to T. compacta by Arthur (1995)), T. centrostrigata, T. heterodentata, and Trichodina sp.

14 Natividad (1986,1988) examined fishes (Channa striata, Clarias batrachus, Puntius javanicus and Trichogaster pectoralis) from various localities around Laguna Lake, Luzon Island, but did not indicate which host species were infected with Trichodina.

15 Palisoc (1988) noted that Trichodina was among the parasites found on tilapia, milkfish, dalag and carp in Laguna Lake but did not indicate on which hosts individual parasite taxa were found.

16 The report of Albaladejo and Arthur (1989) pertains to goldfish imported from Hongkong for the ornamental fish trade.

17 The reports of of Lumanlan et al. (1990, 1992) involve species imported for aquaculture and the aquarium fish trade which were examined in Quezon City.

18 Recent phylogenetic analyses conducted by Siddall et al. (1995) using ultrastructural characteristics of developmental stages and analysis of rDNA have indicated that the myxozoans are actually highly derived parasitic cnidarians. We retain the Phylum Myxozoa pending additional systematic studies supporting this conclusion and integrating the classifications of these two phyla.

19 Records contained in the abstract and paper of Lumanlan et al. (1990, 1992) involve fishes imported for aquaculture and the aquarium fish trade which were examined in in Quezon City.

20 This record involves fishes imported for aquaculture and the aquarium fish trade which were examined in Quezon City.

21 Lumanlan et al. (1992) reported Cloromyxum spp. from clown loach and barred Siamese catfish imported from Hongkong and Singapore, respectively, for the ornamental fish trade.

22 Velasquez (1986b) noted that Puntius amarus, P. binotatus, P. disa, P. manalak and Spratellicypris palata were the species of fish parasitized but in this preliminary abstract, she did not indicate which parasite taxa occur in individual host species.

23 Fischthal and Kuntz (1964d) gave the site of infection as the intestine; however, as noted by Yamaguti (1971), members of the genus Elongoparorchis are typically parasites of the swim bladders of marine catfishes (family Ariidae).

24 The listing of this species from Arius thalassinus (syn. of Netuma thalassina ) by Velasquez (1974) was apparently based on specimens recorded by her (Velasquez 1975a) as being from Coron, Palawan Island.

25 As Puntius binotatus is a freshwater cyprinid, this report may involve a host misidentification.

26 Velasquez (1962) suggested that the report of this species from Glossogobius giuris by Tubangui and Masiluñgan (1944) may have involved a host misidentification.
