H. witenbergi View in CoL Tret’iakova, 1940

Type host. Gadwall, Anas strepera Linnaeus (Syn. Chaulellasmus streperus Linnaeus) ( Anseriformes : Anatidae )— Pavlovskaya (1962).

Type locality. Russian Federation ( USSR [ CIS]); specific type locality unknown—Pavlovskaya (1962).

Remarks. Tret’iakova (1940) could not be obtained; however, Bashkirova (1950) and McDonald (1969a, 1969b, 1981) have provided additional information concerning this species. McDonald (1969a, 1969b) indicated that this species was described in a thesis or dissertation by Tret’iakova from Russia in 1940, but to our knowledge it was never formally described in a publication. This species is currently listed as an unverified species by Global Species and the Host-Parasite Database, Natural History Museum, London. According to Bashkirova (1950) and McDonald (1981), this species was described as having the uterine loops confined to the posterior third of the body; however, the genital pore is prepharyngeal and it is likely that the specimen used in the description was abnormal, or had not developed enough eggs to fill the anterior portion of the uterus. As this species was described in a dissertation and apparently never formally published, it should be considered a nomen nudum and therefore was not included in our key to the species currently assigned to Hyptiasmus . As far as we can determine, no oral or ventral sucker was described—Bashkirova (1950) and McDonald (1981).
