New Host, geographical record and a synonym for Phyllodistomum Spatula Odhner, 1902 (Trematoda, Gorgoderidae)

Abstract

In the present note Phyllodistomum spatula Odhner, 1902 is recorded for the first time from Brazil and in a New host Colossoma macropomum (Cuvier, 1818) (Pisces, serrasalmidae), and Plyllodistomum spatulaeforme Odhner, 1902 is considered its synonym.<br>Na presente nota Phyllodistomum spatula Odhner, 1902 é assinada pela primeira vez no Brasil, e em novo hospedeiro Colossoma macropomum (Cuvier, 1818); e Phyllodistomum spatulaeforme Odhner, 1902, considerado seu sinônimo

Digenea of Hoplias intermedius and Hoplias malabaricus (Actinopterygii, Erythrinidae) from upper São Francisco River, Brazil

“…Remarks: Our specimens are similar to those reported by Lewis (1935) and Fernandes (1984). The specimens of P. spatula found in Hoplias spp.…”

“…The specimens of P. spatula found in Hoplias spp. in this study are larger than those collected by Fernandes (1984) in the body cavity of Colossoma macropomum (Cuvier, 1816). However, the size of the specimens found in the present study, and those obtained by Fernandes (op.…”

“…Hoplias intermedius (Günther, 1864) (Hoplias lacerdae species group, following OYAKAWA & MATTOX, 2009) and Hoplias malabaricus (Bloch, 1794) are to Kanev et al (2002), Niewiadomska (2002) (metacercariae), Campbell (2008), and (adult digeneans). The identification of the metacercariae is according to Kohn et al (1995), Niewiadomska (2002), and Benigno et al (2014), and the identification of adult specimens was done according to Fernandes (1984) and Kohn et al (1985). The ecological descriptors, prevalence, mean intensity, and mean abundance followed the methods of Bush et al (1997).…”

Digenea parasites of Acestrorhynchus falcirostris (Osteichthyes, Acestrorhynchidae) in the state of Amazonas, Brazil

“…In Brazil, it was reported by Fernandes (1984) in Colossoma macropomum Cuvier, 1816 and by Costa et al (2015) in Hoplias intermedius Günther, 1864 and H. malabaricus. The specimen studied here is in agreement with those already reported having eggs slightly wider.…”

Morphological and molecular data on Phyllodistomum (Digenea: Gorgoderidae) from Brazil, with the description of a new species parasitizing Hoplias malabaricus (Bloch, 1794) (Osteichthyes, Erythrinidae)

“…This latter species has also been recorded in H. malabaricus in the Batalha River, São Paulo state (Gião et al 2020), although considering host association, it is more likely that the report may correspond with the new species we describe in this study. One species, P. spatula, seems to be widely distributed in Brazilian fishes and was first recorded in Ceará, Brazil, by Fernandes (1984) from C. macropomum (Cuvier, 1818). Later, it was reported infecting H. malabaricus and H. intermedius from the São Francisco River from Minas Gerais state (Costa et al 2015) and Acestrorhynchus falcirostris Cuvier, 1819 from the municipality of Manus, Amazonas state (Fernandes et al 2017).…”
