Treatment

S. vicarium ( Arnsdorff, 1908) View in CoL n. comb.

Type host. Purple sandpiper, Calidris maritima Brünnich (Syn. Arquatella maritime [Gmelin]) ( Charadriiformes : Scolopacidae ).

Type locality. Labrador, Canada.

Additional hosts. Eurasian curlew, Numenius arquata (Linnaeus) and dunlin, Calidris alpina (Linnaeus) (Syn. Tringa alpina Linnaeus ) ( Charadriiformes : Scolopacidae )— Yamaguti (1971); common greenshank, Tringa nebularia (Gunnerus) ( Charadriiformes : Scolopacidae )— Bourgat et al. (1999).

Additional localities. Europe, specific locality unknown—Yamaguti (1971); Togolese Republic ( Togo), Africa—Bourgat et al. (1999).

Previously proposed synonym. Cyclocoelum mehrii Khan, 1935 (= Selfcoelum mehrii [ Khan, 1935] n. comb.)— Bashkirova (1950); Dubois (1959).

Remarks. This species was originally described as Monostomum vicarium Arnsdorff, 1908 . It was redescribed as Cyclocoelum vicarium ( Arnsdorff, 1908) by Harrah (1922). It was considered a synonym of Cyclocoelum ovopunctatum Stossich, 1902 (= Selfcoelum ovopunctatum [ Stossich, 1902] n. comb.) by Bashkirova (1950) and Dubois (1959), and of Cyclocoelum obscurum ( Leidy, 1887) by Joyeux & Baer (1927). The original description of this species by Arnsdorff (1908) apparently was based on two separate species representing different genera in two separate subfamilies. Figure 1 View FIGURES 1 – 4 of the original description likely represents Selfcoelum vicarium n. comb. (Syn. Monostomum vicarium ) because it has an intertesticular ovary forming a triangle with the testes (Cyclocoelinae), a genital pore that is postpharyngeal and the vitelline fields are not confluent posteriorly (= Selfcoelum ). The second possible species, as shown in Fig. 2 View FIGURES 1 – 4 , appears to have a pretesticular ovary forming a triangle with the testes (Haematotrephinae), a genital pore that is postpharyngeal, vitelline fields that are not confluent posteriorly and the testes are oblique, and it would likely be assigned to Haematotrephus . However, with the lack of information concerning this second species, we have not distinguished it as a distinct species and have not included it in our key to the species of Haematotrephus . No oral or ventral sucker described—Arnsdorff (1908); Kossack (1911) and Bashkirova (1950).
