Remarks. Although originally described as Corpopyrum capellae Yamaguti, 1933, this species was considered to be a synonym of Cyclocoelum (H.) tringae Stossich, 1902 (= Neohaematotrephus tringae [Stossich, 1902] n. comb.) by Dubois (1959). It has a pretesticular ovary that forms a triangle with the diagonal testes (Haematotrephinae), the genital pore is postpharyngeal and the vitelline fields are not confluent posteriorly, placing it in Haematotrephus . No oral or ventral sucker described—Yamaguti (1933).
