| Summary: | H. vigisi Savinov, 1960 Type host. Greater scaup, Aythya marila (Linnaeus) (Anseriformes: Anatidae). Type locality. Russian Federation; specific type locality unknown. Remarks. Savinov (1960) could not be obtained; however, McDonald (1969a, 1969b, 1981) has provided a limited amount of additional information concerning this species, including an illustration (Fig. 17.2), but gave no measurements. McDonald (1981) indicated that there was a bean-shaped supplementary body attached to the posterior end of each testis. Such a structure would be unusual, but in senescing adult flukes it is not unusual to have the peripheries of the testes separate from the parenchyma leaving a space that might be construed as an additional structure. As far as we can determine this species was never adequately described and should be considered a species inquirenda and it was not included in our key to the species currently assigned to Hyptiasmus. No oral or ventral sucker described—McDonald, (1981). ... : Published as part of Dronen, Norman O. & Blend, Charles K., 2015, Updated keys to the genera in the subfamilies of Cyclocoelidae Stossich, 1902, including a reconsideration of species assignments, species keys and the proposal of a new genus in Szidatitreminae Dronen, 2007, pp. 1-100 in Zootaxa 4053 (1) on page 65, DOI: 10.11646/zootaxa.4053.1.1, http://zenodo.org/record/237117 ... |
