Abstract

Cestodes were collected from deep-sea sharks caught off New Caledonia, South Pacific. Vittirhynchus squali n. g., n. sp. (Trypanorhyncha: Gilquiniidae) is described from the spiral valve of Squalus melanurus Fourmanoir & Rivaton. The new genus possesses four bothria and a typical heteroacanthous metabasal armature but has a file of three macrohooks forming a short chainette on the internal surface of the basal armature. Sagittirhynchus aculeatus n. g., n. sp., from the spiral valve of Centrophorus sp. (undescribed), also has four bothria and a typical heteroacanthous armature but lacks a distinctive basal swelling and has the final hooks of each principal row prominently enlarged. Gilquinia minor n. sp., from the spiral valve of Centrophorus sp. (undescribed), is distinguished by the presence of only five hooks per principal row compared with eight in congeners. Gilquinia sp. is reported from Squalus melanurus. G. robertsoni Beveridge, 1990 is reported from S. megalops (Macleay).

Résumé

Les cestodes ont été collectées de requins pêchés au large de la Nouvelle-Calédonie, Pacifique Sud. Vittirhynchus squali n. g., n. sp. (Trypanorhyncha: Gilquiniidae) est décrit de la valvule spirale de Squalus melanurus Fourmanoir & Rivaton. Le nouveau genre possède quatre bothries et une armature métabasale hétéracanthe typique, mais a une file de trois grands crochets en forme de chaînette courte sur la face interne de l’armature basale. Sagittirhynchus aculeatus n. g., n. sp., de la valvule spirale de Centrophorus sp. (non décrit), a aussi quatre bothries et une armature hétéracanthe typique, mais n’a pas d’épaississement basal distinctif, et a les crochets finaux de chaque rangée principale plus grands. Gilquinia minor n. sp., de la valvule spirale de Centrophorus sp. (non décrit), se distingue par la présence de seulement cinq crochets par rangée principale, en comparaison avec huit chez ses congénères. Gilquinia sp. est mentionné de Squalus melanurus. G. robertsoni Beveridge, 1990 est mentionné de S. megalops (Macleay).
