A. elongatum (Harrah, 1921) n. comb. Type host. Harrah (1921) listed “ Cyanopolius cyanus ” as the host; however, we could not confirm this genus or species. It is apparently the azure-winged magpie, Cyanopica cyanus Pallas (Passeriformes: Corvidae)— Harrah (1921). Type locality. Nanjing, People’s Republic of China. Additional hosts. Species of Myiophoneus Temminck & Laugier (Syn. Myophonus Temminck) (Passeriformes: Muscicapidae); common sandpiper, Tringa hypoleucos Linnaeus (Charadriiformes: Scolopacidae); grey catbird, Dumetella carolinensis (Linnaeus) (Passeriformes: Mimidae); species of Passer Brisson (Passeriformes: Passeridae); species of Pica Brisson (Passeriformes: Corvidae); species of Gallus Brisson (Galliformes: Phasianidae)— Yamaguti (1971). Additional localities. India, South America, USA, and Vietnam—Yamaguti (1971). Remarks. This species was originally described as Cyclocoelum elongatum Harrah, 1921. It was considered to be a synonym of Cyclocoelum sharadi Bhalerao, 1935 (= Morishitium sharadi [Bhalerao, 1935]), Cyclocoelum bivesiculatum Prudhoe, 1944, Cyclocoelum (Pseudhyptiasmus) dollfusi Timon-David, 1950 (= Morishitium dollfusi [Timon-David, 1950]), and Cyclocoelum (Pseudhyptiasmus) sinhaladvipa Fernando, 1950 (transferred to Morishitium by Yamaguti 1958) by Dubois (1959). This species has the intertesticular ovary nearly in a straight line with the nearly tandem testes (Hyptiasminae), a postpharyngeal genital pore and the vitelline fields are confluent posteriorly, placing it in Allopyge. Rudimentary oral sucker present—Harrah (1921).
