H. tringae (Brandes, 1892) n. comb. Type host. Dunlin, Calidris alpina (Linnaeus) (Syn. Tringa variabilis Meyer) (Charadriiformes: Scolopacidae). Type locality. Sinai Peninsula, Egypt—Yamaguti (1971). Additional hosts. Green sandpiper, Tringa ochropus Linnaeus (Syn. Totanus ochropus Temminck) (Charadriiformes: Scolopacidae)— Yamaguti (1971); American avocet, Recurvirostra americana Gmelin (Charadriiformes: Recurvirostridae)— Garcia & Canaris (1987). Additional locality. Colorado—Garcia & Canaris (1987). Previously proposed synonyms. Cyclocoelum taxorchis Johnston, 1917; Cyclocoelum wilsoni Harrah, 1922 (= Wardianum wilsoni [Harrah, 1922]); Cyclocoelum triangularum Harrah, 1922; Corpopyrum capellae Yamaguti, 1933 (= Haematotrephus capellae [Yamaguti, 1933] n. comb.)— Dubois (1959); Haematotrephus tringae (Brandes, 1892), Corpopyrum tringae (Brandes, 1892)— Joyeux & Baer (1927). Remarks. This species was originally described as Monostomum tringae Brandes, 1892, but it was considered to be in Haematotrephus by Bashkirova (1950), and in Corpopyrum (= Haematotrephus) by Witenberg (1923) and Yamaguti (1958, 1971). It was redescribed from the original material of Brandes (1892) from the Berlin Museum (# 2459) by Kossack (1911) who indicated that the specimen was of poor quality and that the cirrus sac was not visable. Kossack (1911) considered this species to be in Cyclocoelum because it has a prepharyngeal genital pore; however, the ovary is pretesticular (opposite the anterior testis) forming a triangle with the testes (Haematotrephinae) and the vitelline fields are not confluent posteriorly placing it in Harrahium. Dronen (2007 a) followed Kanev et al. (2002 a) by considering Harrahium to be a synonym of Haematotrephus; however, species of Haematotrephus have a postpharyngeal genital pore. This species was considered to be a synonym of Haematotrephus lanceolatum (Wedl, 1858) by Macko & Feige (1960). No oral or ventral sucker described— Kossack (1911); Bashkirova (1950). A “small suction plug” was ...
