H. nebularium ( Khan, 1935) View in CoL n. comb.

Type host. Common greenshank, Tringa nebularia (Gunnerus) (Syn. Glottis nebularia Gunnerus ) ( Charadriiformes : Scolopacidae ).

Type locality. Allahabad, Allahabad District, India.

Remarks. Originally described as Cyclocoelum nebularium Khan, 1935 , this species was transferred to Corpopyrum (= Haematotrephus ) by Yamaguti (1958). It was considered to be a synonym of Cyclocoelum (Haematotrephus) kossacki ( Witenberg, 1923) (= H. kossacki [ Witenberg, 1923] n. comb.) by Dubois (1965). The pretesticular ovary forms a triangle with the testes (Haematotrephinae), the genital pore is postpharyngeal (see Fig. 1 View FIGURES 1 – 4 of the original description), and the vitelline fields were described as being confluent except for in one specimen where they were not confluent ( Khan 1935). As previously mentioned, the posterior confluence of the vitelline fields is often hidden in cyclocoelids by the egg-laden uterus and cyclocoel, but it is also possible that more than one species was used in the original description of this species. Braun (1901) mistakenly considered the pharynx to be the oral sucker in cyclocoelids—Harrah (1922) and Khan (1935). No oral or ventral suckers described—Khan (1935); Harrah (1922) and Bashkirova (1950).
