Oesophagotrema mediterranea n. gen., n. sp. (Digenea, Zoogonidae) is described from
the needlefi sh Tylosurus acus imperialis (Beloniformes, Belonidae) off the Tunisian
coast. Oesophagotrema n. gen. is distinguished from all other Lepidophyllinae
genera by the combination of a prominent rounded ventral sucker, caeca reaching
to the anterior edge of the posterior testis, testes arranged in tandem in the middle
third of the hindbody and the vitellarium in symmetrical lateral bunches located
between the ovary and anterior testis. Th is species shows a typical specifi c site of
infection within the digestive tract, i.e., the oesophagus and vomer teeth. Th e
position of this zoogonid digenean on the oesophagus is discussed.
