W. taxorchis ( Johnston, 1917)

Type host. This host was originally listed as Limosa novae-hollandiae by Johnston (1917). The identification of this bird could not be confirmed because we were not able to find a listing of this species from Australia. This godwit species may be the bar-tailed godwit, Limosa lapponica (Linnaeus) ( Charadriiformes : Scolopacidae ), but the black-tailed godwit, Limosa limosa (Linnaeus) ( Charadriiformes : Scolopacidae ), also is known from Australia. Allison (2001) reported W. taxorchis from a subspecies of bar-tailed godwit, Limosa lapponica baueri Naumann , from the South Island of New Zealand.

Type locality. Lord Howe Island, off Australia.

Additional hosts. Black-winged or common stilt, Himantopus himantopus (Linnaeus) (Syn. H. leucocephalus Gould ) ( Charadriiformes : Scolopacidae ) and the common snipe, Gallinago gallinago (Linnaeus) ( Charadriiformes : Scolopacidae )— Yamaguti (1958, 1971).

Previously proposed synonyms. Cyclocoelum wilsoni Harrah, 1922 (= W. wilsoni [Harrah, 1912]), Cyclocoelum triangularum Harrah, 1922 (= W. triangulare [ Harrah, 1922]), Corpopyrum wilsoni ( Harrah, 1922) (= W. wilsoni [ Harrah, 1922]) and W. triangulare ( Harrah, 1922) — Joyeux & Baer (1927).

Remarks. This species was originally described as Cyclocoelum taxorchis Johnston, 1917 , but considered to be in Wardianum byYamaguti (1958, 1971). It was considered to be a synonym of Cyclocoelum (H.) tringae Stossich, 1902 (= Neohaematotrephus tringae [ Stossich, 1902] n. comb.) by Dubois (1959) and of Haematotrephus lanceolatum ( Wedl, 1858) by Macko & Feige (1960). No oral or ventral sucker described—Johnston (1917) and Bashkirova (1950).
