On a Trematode Allopyge Undulatus N.SP. Parasitic in Lilford's Crane (Megalornis grus Lilfordi)

Abstract

While studying a collection of roundworm parasites from animals dying in the Philadelphia Zoological Garden, accounts of which appeared in 1929 and 1931, I found ten flukes in it, one of which proved to be new. Two common distomes in the lot, Renifer ellipticus Pratt 1903 and Opisthorchis tenuicollis (Rud. 1819) are from new hosts; the former from an American beaver (Castor canadensis) and the latter from a Canadian lynx (Felis canadensis). The one rare monostome found in the lot is recognised as a new species of the genus Allopyge Johnston 1913 in the family Cyclocoelidae and is named Allopyge undulatus n.sp. It was found in the thoracic air sacs of Lilford's crane (Megalornis grus lilfordi).
