A new species of Triloculotrema Kearn, 1993 (Monogenea: Monocotylidae) from a deep-sea shark, the blacktailed spurdog Squalus melanurus (Squaliformes: Squalidae), off New Caledonia

Abstract

Triloculotrema chisholmae n. sp. is described from three specimens collected from the nasal tissues of a deep-sea shark, the blacktailed spurdog Squalus melanurus Fourmanoir & Rivaton, caught off New Caledonia, South Pacific. The new species is distinguished from the only other and type-species of the genus, T. japanicae Kearn, 1993, by the morphology of the sclerotised male copulatory organ (shorter and straight versus curved) and shorter hamuli.

Résumé

Triloculotrema chisholmae n. sp. est décrit à partir de trois spécimens récoltés dans les tissus nasaux d’un requin de profondeur, l’aiguillat à queue noire Squalus melanurus Fourmanoir & Rivaton, pêché au large de la Nouvelle-Calédonie, Pacifique Sud. La nouvelle espèce est distinguée de l’espèce-type et seule autre espèce du genre, T. japanicae Kearn, 1993, par la morphologie de l’appareil copulateur mâle sclérifié (plus court, et droit au lieu de courbe), et par des hamuli plus courts.

Jean-Raymond Olivier generously provided the live shark. Parasites were collected by Ian Whittington, Elisabeth Perkins and Vanessa Glennon, during a visit to New Caledonia, and by Isabelle Mary. Cyndie Dupoux skilfully prepared the slides. Bernard Séret (IRD, Paris) identified the shark (from photographs) and provided information on its geographical distribution. Leslie Chisholm (SAM, Adelaide) thoroughly edited a draft of the manuscript.
