Allopyge Johnston, 1913

(Members of this genus have a postpharyngeal genital pore and the vitelline fields are confluent posteriorly) ( Table 18 )

Diagnosis. Cyclocoelidae ; Hyptiasminae. Body, lanceolate to linguiform, sometimes tapered anteriorly. Rudimentary oral sucker present or not; rudimentary ventral sucker absent. Genital pore postpharyngeal, located some distance posterior to pharynx in some species (e.g. A. antigones Johnston, 1913 and A. undulatus Canavan, 1934 ). Ovary intertesticular nearly in line with the tandem or nearly tandem testes near posterior arch of cyclocoel. Uterine coils often overreaching ceca laterally, commonly invading posttesticular space, infrequently intertesticular. Vitelline fields confluent posteriorly forming a posteriorly- directed, tail-like extension in some species (e.g. A. americanensis Dronen & Blend, 2005 ). Parasites in body cavity, air sacs, lungs and nasal sinuses of birds.
