Calydiscoides limae sp. nov. (Monogenea, Diplectanidae) from Pentapodus aureofasciatus (Perciformes, Nemipteridae) off New Caledonia

Article

Abstract

Calydiscoides limae sp. nov. is described from the nemipterid Pentapodus aureofasciatus Russell, 2001 caught along the barrier reef off New Caledonia, South Pacific. The new species is characterised by its male copulatory organ, with a distal blade and a lateral spur, and its female sclerotised organ, with a sphere and a thin tube. Its lamellodiscs always have 7 concentric lamellae, with the 3 internal lamellae complete and the 4 peripheral lamellae progressively less and less complete; measurements of the angles occupied by the lamellae in numerous specimens showed that the lamellodisc structure shows little variation among individuals.

Résumé

Calydiscoides limae sp. nov. est décrit du Nemipteridae Pentapodus aureofasciatus Russell, 2001 pêché le long du récifbarrière de Nouvelle-Calédonie, Pacifique Sud. La nouvelle espèce est caractérisée par son organe copulateur mâle, avec une lame distale et un éperon latéral, et par son organe sclérifié femelle, avec une sphère et un tube fin. Ses lamellodisques ont toujours 7 lamelles concentriques, avec les 3 lamelles internes complètes et les 4 lamelles périphériques progressivement de moins en moins complètes. La mesure des angles occupés par les lamelles chez de nombreux spécimens montre que la structure des lamellodisques est peu variable entre les individus.
