A. ominosus ( Kossack, 1911)

Type host. Given as Grus cinerea Bechstein in the original description, but this species of bird could not be verified. It is likely that this is the grey heron, Ardea cinerea Linnaeus ( Pelecaniformes : Ardeidae ) but it also could be the grey or common crane, Grus grus (Linnaeus) ( Gruiformes : Gruidae ).

Type locality. Germany; specific type locality unknown.

Additional hosts. Species of Ardea Linnaeus (Syn. of Megalornis Gray ) ( Pelecaniformes : Ardeidae )— Yamaguti (1971).

Additional locality. Europe—Yamaguti (1971).

Remarks. This species was originally described as Hyptiasmus ominosus Kossack, 1911 by Kossack (1911) from materials labelled as “ Monostomum microstomum Creplin, 1829 ” from the Greifwald Collection housed in the Berlin Museum and from two specimens (No. 2956) from the Berlin Collection labelled “ Monostomum mutabile Zeder ”. It was transferred to Morishitium by Yamag uti (1958), but it was considered to be in Hyptiasmus by Dubois (1930); in Morishitium by Gupta & Gupta (1979); and in Allopyge by Bashkirova (1950) and Dronen & Blend (2005). Dubois (1959) considered Allopyge undulatus Canavan, 1934 to be a synonym of this species. The genital pore opens immediately above the posterior margin of the intestinal bifurcation and the vitelline fields are confluent posteriorly. No oral or ventral suckers described—Kossack (1911) and Bashkirova (1950).
