Examinations of nematodes collected from some marine fishes off the southwestern coast of Java, Indonesia in 2000 and 2001 revealed the presence of the following six species: ascaridoids Ichthyascaris grandis sp. n. from the intestine of Lophiomus setigerus (Vahl), I. cf. longispicula Li, Liu, Liu et Zhang, 2012 from the intestine of Conger cinereus Rüppel, Ichthyascaris sp. from the body cavity of Lobotes surinamensis (Bloch), and Raphidascaroides halieutaeae Yin, 1983 from the intestine of Halieutaea stellata (Vahl), and philometrids Philometra ivaschkini Parukhin, 1976 from the stomach wall of Trichiurus lepturus Linnaeus and P. psettoditis Moravec, Walter et Yuniar, 2012 from the body cavity (liver) of Psettodes erumei (Bloch et Schneider). Descriptions of these nematodes based on light and scanning electron microscopical studies are provided. The new species I. grandis sp. n. is mainly characterised by large body measurements (males and females up to 41.8 mm and 73.6 mm long, respectively), the length of spicules (0.99-1.05 mm), the tail tip usually without rudimentary spines and by the presence of 44-53 pairs of caudal papillae, eight to twelve of which being postanals. In addition to new data on the morphology of R. halieutaeae and other nematodes recorded, the 11 species of Raphidascaroides Yamaguti, 1941 poorly described from marine fishes in South Asia and reviewed in the monograph of Sood (2017) are considered species inquirendae and incertae sedis.

Based on light and scanning electron microscopical studies, two new species of Philometra Costa, 1845 (Nematoda: Philometridae) are described from two species of Mycteroperca Gill (Serranidae), marine perciform fishes, in coastal waters off Florida, USA: Philometra deburonae n. sp. from the inner side of operculum of the yellowfin grouper Mycteroperca venenosa (L.) and P. incognita n. sp. from the ovary of the gag M. microlepis (Goode & Bean). Philometra deburonae n. sp. is mainly characterised by the body length of males (1.90-2.38 mm), the length of the spicules (78-84 µm) and gubernaculum (54 µm) and the presence of small outer cephalic papillae, a pair of fairly large caudal projections and the oesophageal gland extending anteriorly beyond the nerve-ring in subgravid females. Philometra incognita n. sp. is distinguished by the caudal mound consisting of two lateral reniform parts widely separated dorsally from each other, the absence of a pair of large papillae situated posteriorly to the cloaca, the shape and structure of the distal end of the gubernaculum plus the lengths of the spicules (117-141 µm) and gubernaculum (60-81 µm) in the male, the absence of caudal projections and the comparatively large larvae in the uterus (660-675 µm long) of the gravid female, as well as, the body length of both males (2.45-3.11 mm) and gravid females (120-180 mm). The present descriptions of an additional two new philometrids increases the number of recorded nominal species of Philometra parasitising groupers (Serranidae) in the Gulf of Mexico to nine.

A recent examination of newly obtained specimens of philometrid nematodes (Philometridae) parasitising carangid and serranid fishes off New Caledonia, South Pacific, revealed the presence of several nematodes of the genus Philometra Costa, 1845, including three new species: P. austropacifica n. sp. (males and females) from the ovary of Alepes vari (Carangidae), P. piscaria n. sp. (males) from the ovary of Epinephelus coioides (Serranidae), and P. selaris n. sp. (males) probably from the abdominal cavity (found in washings) of Selar crumenophthalmus (Carangidae). The new species are characterised mainly by the length and structure of the spicules and gubernaculum, body size, their location in the host and the type of host. Philometra austropacifica n. sp. is the first known nominal gonad-infecting species of Philometra parasitising a carangid fish. In addition, the gravid female of P. fasciati Moravec & Justine, 2008 from the ovary of Epinephelus fasciatus (Serranidae) is described for the first time. Carangid host fish were identified by both morphology and DNA barcoding.

Une étude récente de spécimens nouvellement obtenus de nématodes Philometridae parasitant des poissons Carangidae et Serranidae de Nouvelle-Calédonie, dans le Pacifique Sud, a révélé la présence de plusieurs nématodes du genre Philometra Costa, 1845, dont trois nouvelles espèces : P. austropacifica n. sp. (mâles et femelles) de l’ovaire de Alepes vari (Carangidae), P. piscaria n. sp. (mâles) de l’ovaire d’Epinephelus coioides (Serranidae), et P. selaris n. sp. (mâles) probablement de la cavité abdominale (dans des lavages) de Selar crumenophthalmus (Carangidae). Les nouvelles espèces sont principalement caractérisées par la longueur et la structure des spicules et du gubernaculum, la taille du corps, par leur localisation dans l’hôte et par le type d’hôte. Philometra austropacifica n. sp. est la première espèce nominale connue de Philometra parasitant les gonades d’un Carangidae. En outre, la femelle gravide de P. fasciati Moravec et Justine, 2008 est décrite pour la première fois à partir de l’ovaire d’Epinephelus fasciatus (Serranidae). Les poissons hôtes Carangidae ont été identifiés à la fois par la morphologie et des codes-barres ADN.

Based on light and electron microscopical studies, the following four species of Philometra Costa, 1845 (Nematoda: Philometridae) are described from marine fishes from off Basrah, southern Iraq (Arabian Gulf): P. brachiri n. sp. (males and females) from the ovary of the Oriental sole Brachirus orientalis (Bloch & Schneider) (Pleuronectiformes; Soleidae), P. piscaria Moravec & Justine, 2014 (female) from the ovary of the orange-spotted grouper Epinephelus coioides (Hamilton) (Perciformes: Serranidae), P. otolithi Moravec & Manoharan, 2013 (male and females) from the ovary of the tigerteeth croaker Otolithes ruber (Bloch & Schneider) (Perciformes: Sciaenidae) and P. tricornuta n. sp. (female) from the musculature of the caudal peduncle of the greater lizardfish Saurida tumbil (Bloch) (Aulopiformes: Synodontidae). Philometra brachiri is mainly characterised by the structure of the distal tip of the gubernaculum and the length of the spicules (132-135 μm) in male. Philometra tricornuta is distinguished by the presence of three large sclerotised oesophageal teeth and two tandem bulbous inflations at the anterior end of oesophagus in female. The female of P. piscaria is described for the first time. Philometra brachiri is the first species of this genus described from a fish belonging to the family Soleidae. The findings of P. piscaria and P. otolithi in Iraqi marine waters represent new geographical records.
