Otodistomum cestoides (Van Beneden, 1871) from two species of skates taken in chilean waters

Abstract

Otodistomum cestoides (van Beneden, 1871) (Azygiidae: Digenea) is reported for the first time from Psammobatis scobina and Raja flavirostris. The skates were caught off the coast of San Antonio, Chile.<br>Otodistomum cestoides (van Beneden, 1871) é encontrado pela primeira vez em Psammobatis scobina e Raja flavirostris. As raias foram apanhadas ao longo da costa do Chile

Digenea and acanthocephala of elasmobranch fishes from the southern coast of Brazil

“…According to Brinkman Jr (1988) life-cycles of the parasites should be investigated to support this proposition. Nevertheless, we consider our specimens to be O. veliporum based on the fact that the differences now observed in both species may be related to the size of body, compressing conditions, different hosts, and egg thickness that is 2-6 µm in our specimens, compared to 6-10 µm previously reported for O. veliporum (Dollfus 1937, Rees 1953, Skrjabin & Guschanskaya 1958, Caballero & Caballero 1969, Yamaguti 1971; and 3-5.3 µm for O. cestoides (Manter 1926, Dollfus 1937, Miller 1941, Van Cleave & Vaughn 1941, Skrjabin & Guschanskaya 1958, Yamaguti 1971, Gibson 1976a, Threlfall & Carvajal 1986). …”

Comunidades de parásitos de dos tiburones, Etmopterus granulosus (Squaliformes) y Schroederichthys bivius (Carcharhiniformes), del sur de Chile

“…Otodistomum veliporum is the only valid species in the genus, and has been found in fish from the southern Atlantic and Pacific coasts of South America (Kohn et al 2007). Previously, it has been recorded as Otodistomum cestoides (van Beneden, 1871) in batoids, such as Psammobatis scobina (Philippi, 1857) and Dipturus flavirostris (Philippi, 1892) in San Antonio, Central-Chile (Threlfall & Carvajal, 1986) Subphylum: Cestoda Order: Phyllobothriidea Family: undetermined Species: undetermined (Fig. 2 D-E) Ten mature specimens were found in the spiral valve of E. granulosus.…”

On the occurrence of the digenean Otodistomum veliporum in the spiracle of the kitefin shark Dalatias licha

“…All members of Otodistomum genus were revised and redescribed by GIBSON & BRAY (1977). This genus has been recorded from sub-tropical, temperate, sub-Artic and sub-Antartic regions (THRELFALL & CARVAJAL, 1986;ZDZITOWIECKI & PISANO, 1996). GIBSON & BRAY (1977) reported the species Otodistomum veliporum for the Atlantic and the Mediterranean, in particular as host in bony fish and elasmobranchs from waters off Sicily.…”
