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).
