Cyclocoelum Brandes, 1892 View in CoL

(Members of this genus have a prepharyngeal genital pore and the vitelline fields are not confluent posteriorly) ( Tables 1 View TABLE 1 & 2 View TABLE 2 )

Diagnosis. Cyclocoelidae ; Cyclocoelinae. Body lanceolate to linguiform, often tapered anteriorly. Rudimentary oral sucker commonly present; rudimentary ventral sucker present in some species. Genital pore prepharyngeal. Ovary intertesticular forming a triangle with oblique testes near posterior arch of cyclocoel. Uterine coils often intercecal, overlapping ceca laterally in some species. Vitelline fields not confluent posteriorly. Parasites in air sacs, lungs, and infraorbital and nasal sinuses of birds.

Remarks. Note that Cyclocoelum neivai ( Travassos, 1921) of Yamaguti (1971) originally was described from an unknown species of anatid in Tangue do Piauí (Piauhy), Brazil as Typhlocoelum neivai Travassos, 1921 . Later Travassos (1929) erected Neivaia Travassos, 1929 and transferred this species into this new genus. Dubois (1959) considered this species to be Neivaia cymbium ( Diesing, 1850) (Typhlocoelidae) . Travassos (1921) and Feizullaev (1980) considered it to be in Typhlocoelinae, but Kanev et al. (2002b) erected Neivaniinae Kanev, Radev & Fried, 2002 to accommodate this species, where it currently resides. No oral or ventral sucker described—Travassos (1921), Bashkirova (1950).

Also, although Cyclocoelum orientale parvitestium Witenberg, 1923 from the common greenshank, Tringa nebularia (Gunnerus) (Syns. Glottis nebularia Gunnerus , Totanus glottis [Gunnerus]) ( Charadriiformes : Scolopacidae ); and the wood sandpiper, Tringa glareola Linnaeus (Syn Totanus glareola Gmelin ) from Turkestan, Kazakstan, was originally proposed by Witenberg (1923), this subspecies was later considered by him to be invalid—Witenberg (1926).
