Echinostoma 'revolutum' (Digenea: Echinostomatidae) species complex revisited: species delimitation based on novel molecular and morphological data gathered in Europe

“…Echinostoma armigerum ; E. callawayense Barker & Noll in Barker, 1915; E. coalitum ; E. trivolvis and Echinoparyphium contiguum Barker & Barston in Barker, 1915 [ 6 , 53 , 54 ], and further eight species have been described in South America (Brazil), i.e. E. barbosai ; E. erraticum Lutz, 1924; E. luisreyi Maldonado, Vieira & Lanfredi, 2003; E. microrchis Lutz, 1924; E. neglectum Lutz, 1924; E. nephrocystis Lutz, 1924; E. rodriguesi Hsu, Lie & Basch, 1968; E. paraensei Lie & Basch, 1967 [ 24 , 55 - 59 ]. In contrast to the opinions of Beaver [ 4 ] and Kanev et al .…”

Echinostoma ` revolutum ¿ (Digenea: Echinostomatidae) species complex revisited: species delimitation based on novel molecular and morphological data gathered in Europe

“…Echinostoma armigerum; E. callawayense Barker & Noll in Barker, 1915; E. coalitum; E. trivolvis and Echinoparyphium contiguum Barker & Barston in Barker, 1915 [6,53,54], and further eight species have been described in South America (Brazil), i.e. E. barbosai; E. erraticum Lutz, 1924 [24,[55][56][57][58][59]. In contrast to the opinions of Beaver [4] and Kanev et al [6] regarding the synonymy of all North American species listed above with E. trivolvis, detailed studies on the morphology of some of the South American species have revealed that these exhibit distinguishing differences [18,24,57,59].…”

“…E. barbosai; E. erraticum Lutz, 1924 [24,[55][56][57][58][59]. In contrast to the opinions of Beaver [4] and Kanev et al [6] regarding the synonymy of all North American species listed above with E. trivolvis, detailed studies on the morphology of some of the South American species have revealed that these exhibit distinguishing differences [18,24,57,59]. Comparative approaches to the morphology of North American strains of "E. revolutum" and E. trivolvis during the 'pre-molecular era' have shown that morphometric features of the experimentally raised adult worms can be used to distinguish closely related species [60,61].…”

Two new species of Echinostoma (Digenea: Echinostomatidae) from Argentinean birds

“…Source Present study Dietz (1910) Kohn and Fernandes (1975) AlvesPinto and Melo 2012Lumsden & Fernandes, 1975;Lutz, 1924); and Echinostoma attenuatum Lumsden and Zischke, 1963 found parasitizing Rallus elegans Audubon, and Rallus longirostris Boddaert (Rallidae) from USA (Bates & Meade, 1972;Heard, 1970;Lumsden & Zischke, 1963;Underwood & Dronen, 1986). Echinostoma exile has morphological characteristics compatible with E. jacanae n.…”

“…; however, differs in the arrangement of spines collar (5 angle spines on each side + 33 or 35 spines in a double row). Moreover, the specimens of E. exile described by Kohn and Fernandes (1975) and AlvesPinto and Melo (2012) can be differentiated of the new species by having larger suckers, shorter oesophagus, larger eggs and shorter forebody (notably short vs. long) ( Table 2).…”
