Abstract
Pseudogilquinia pillersi (Southwell, 1929), a poorly known species of trypanorhynch, is redescribed from plerocerci collected from Epinephelus coioides (Hamilton, 1922), Epinephelus malabaricus (Bloch et Schneider, 1801) (Serranidae) and Plectropomus laevis (Lacépède, 1801) (Serranidae) off New Caledonia. These were compared with specimens from Lethrinus atkinsoni Seale, 1910 and Lethrinus miniatus (Forster, 1801) (Lethrinidae) off the north-east coast of Australia as well as syntypes from Protonibea diacantha (Lacépède, 1802) from Sri Lanka. Although size differences were found in parts of the scolex as well as in the sizes of the tentacular hooks, the hook arrangements were identical in all specimens. The differences observed were attributed provisionally to intra-specific variation across a wide geographic and host range.
Abstract
Une espèce de trypanorhynque peu connue, Pseudogilquinia pillersi (Southwell, 1929), est redécrite à partir de plérocerques récoltés chez Epinephelus coioides (Hamilton, 1922), Epinephelus malabaricus (Bloch et Schneider, 1801) et Plectropomus laevis (Lacépède, 1801) (Serranidae) en Nouvelle-Calédonie, et chez Lethrinus atkinsoni Seale, 1910 et Lethrinus miniatus (Forster, 1801) (Lethrinidae) de la côte nord-est de l’Australie, et des syntypes provenant de Protonibea diacantha (Lacépède, 1802) du Sri Lanka. En dépit de la taille différente des constituants du scolex et des crochets des tentacules, l’arrangement des crochets était similaire chez tous les spécimens. Les différences observées ont été provisoirement attribuées à une variation intraspécifique dans une aire géographique étendue et un grande variété d’hôtes.
