Abstract
Based on light and electron microscopical studies of males and mature females two new gonadinfecting species of Philometra Costa 1845 Nematoda Philometridae are described from the ovary of groupers Epinephelus spp Perciformes Serranidae in the Mediterranean Sea off Tunisia near Sfax Philometra aenei n sp from the white grouper E aeneus Geoffroy SaintHilaire and P tunisiensis n sp from the goldblotch grouper E costae Steindachner Identification of both fish hosts was confirmed by barcoding of the infected fish specimens Philometra aenei is mainly characterised by the length of conspicuously distended spicules 108–123 µm the presence of a distinct dorsal barb at the middle region of the gubernaculum and a distinct protuberance consisting of two dorsolateral lamellar parts separated from each other by a smooth median field at its distal tip a Vshaped mound on the male caudal extremity and by the body length of the males 234–305 mm The male of this species was found to possess minute deirids in the cervical region which is quite exceptional within the Philometridae Philometra tunisiensis is distinguished from other gonadinfecting congeneric species parasitising serranids by the length of the needlelike spicules and gubernaculum 201–219 and 78–87 µm respectively spicule length representing 9–11 of body length the gubernaculum/spicules length ratio of 1252–277 the length of oesophagus in the male comprising 15–16 of the body length the absence of a dorsal protuberance on the distal lamellar part of the gubernaculum and a pair of large papillae posterior to the cloaca a dorsally interrupted mound on the male caudal extremity and the body length of the male 201–242 mm The presence of three morphologically very different species of Philometra in congeneric hosts in the Mediterranean Sea confirms a high degree of host specificity of these gonadinfecting nematodes parasitising groupersAuthors’ thanks are due to the staff of the Laboratory of Electron Microscopy Institute of Parasitology Biology Centre of the AS CR České Budějovice for their technical assistance and to Blanka Škoríková of the same Institute for help with illustrations
