Abstract Abstract
Two different gonad-infecting species of Philometra Costa, 1845 were collected from the ovary of marine perciform fishes, the blackspotted croaker Protonibea diacanthus (Sciaenidae) and the John’s snapper Lutjanus johnii (Lutjanidae), from off the northern coast of Australia. Nematodes (males and females) from P. diacanthus represent a new taxon, Philometra protonibeae n. sp., which is mainly characterized by the body length of the males (3.37–3. 90 mm), broad, equally long spicules (length 126–141 μm) and the shape and structure of the gubernaculum with a dorsally lamellate distal tip. The nematodes (only females) from L. johnii may represent an undescribed species, but, because of the absence of conspecific males, they could not be specifically identified. Philometra protonibeae is the fifth nominal gonad-infecting species of this genus recorded from marine fishes in Australian waters and the seventh species of these parasites described from fishes of the family Sciaenidae.

Résumé

Deux espèces différentes de Philometra Costa, 1845, parasites des gonades de poissons, ont été collectées des ovaires de poissons perciformes marins, Protonibea diacanthus (Sciaenidae) et Lutjanus johnii (Lutjanidae), au large de la côte nord de l’Australie. Les nématodes (mâles et femelles) de P. diacanthus représentent un nouveau taxon, Philometra protonibeae n. sp., qui se caractérise principalement par la longueur du corps des mâles (3.37-3.90 mm), des spicules larges et de même longueur (126-141 μm) et la forme et la structure du gubernaculum, qui a une pointe distale dorsalement lamellaire. Les nématodes (seulement femelles) de L. johnii peuvent représenter une espèce non décrite, mais, en raison de l’absence des mâles conspécifiques, n’ont pas pu être identifiés au niveau de l’espèce. Philometra protonibeae est la cinquième espèce nominale de ce genre infectant les gonades qui est mentionnée de poissons marins dans les eaux australiennes et la septième espèce décrite de poissons de la famille Sciaenidae.
