Abstract

Huffmanela plectropomi n. sp. is described from eggs only, which were found in black spots in the mesentery of a coralgrouper, Plectropomus leopardus (Lacépède), caught near Nouméa, New Caledonia, South Pacific. The eggs are 64–76 (mean 69) μm in length and 29–35 (mean 32) μm in width, with a thin shell. The surface of the eggs bears a thick, continuous layer of filaments. The species is distinguished from other members of the genus by the dimensions of its eggs and the characteristics of their surface. This is the first species of Huffmanela Moravec, 1987 to be described from a grouper (Serranidae, Epinephelinae).

Résumé

Huffmanela plectropomi n. sp. est décrit seulement à partir d’œufs, collectés dans des taches noires du mésentère d’une loche saumonée, Plectropomus leopardus (Lacépède), pêchée près de Nouméa, Nouvelle-Calédonie, Pacifique Sud. Les œufs sont longs de 64–76 μm (moyenne 69) et large de 29–35 μm (moyenne 32), avec une coque fine. La surface des œufs porte une couche de filaments épaisse et continue. L’espèce est différenciée des autres espèces du genre par les dimensions de ses œufs et les caractéristiques de leur surface. Ceci est la première espèce d’Huffmanela Moravec, 1987 décrite d’un mérou (Serranidae, Epinephelinae).
