Triloculotrema euzeti n. sp. (Monogenea, Monocotylidae, Merizocotylinae) is described from the nasal tissues of the blackspotted smooth-hound Mustelus punctulatus collected from the coastal marine waters off Tunisia. The new parasite species is distinguished from the other two species of the genus, T. japanicae Kearn, 1993 and T. chisholmae Justine, 2009, by the morphology of the sclerotised male copulatory organ which has longitudinal ridges. The species is also characterised by its oötype with short descending and ascending limbs (long and more convoluted in the other two species). The presence of three peripheral loculi, which is the main characteristic of the genus Triloculotrema Kearn, 1993, is unconfirmed. This is the first description of a species of this genus in the Mediterranean Sea and the first record from a coastal shark.
Résumé
Triloculotrema euzeti n. sp. (Monogenea, Monocotylidae, Merizocotylinae) est décrit des tissus nasaux de l’émissole pointillée Mustelus punctulatus collectée au niveau des côtes de Tunisie. La nouvelle espèce de parasite se distingue des deux autres espèces du genre, T. japanicae Kearn, 1993 et T. chisholmae Justine, 2009, par la morphologie de l’organe copulateur mâle sclérifié qui est pourvu d’arêtes longitudinales. L’espèce est également caractérisée par son ootype avec branches ascendante et descendante courtes (longues et plus contournées chez les deux autres espèces). La présence de trois loculi périphériques au niveau du hapteur, qui est la principale caractéristique du genre Triloculotrema Kearn, 1993, est non confirmée. Ceci est la première description d’une espèce du genre Triloculotrema en Méditerranée et le premier signalement chez un requin côtier.
