Abstract
Raphidascarid nematodes have been the focus of several studies, mainly due to the zoonotic potential of some species, even though the cases are underreported. Due to the difficulty in identifying their larvae, the use of diagnostic techniques involving morphological and molecular analyses has grown in the last 20 years. The present study had as objective the morphological and molecular characterization of the L3 larval types of Hysterothylacium collected in Pomatomus saltatrix and Pagrus pagrus from the Brazilian coast, close to the municipality of Santos, State of São Paulo. Twenty specimens of P. saltatrix were necropsied and Hysterothylacium type V (n = 257) and Hysterothylacium type X (n = 5) larvae were found. Five specimens of P. pagrus were necropsied and all were parasitized by Hysterothylacium type V larvae. The analyses showed a genetic proximity relationship between Hysterothylacium types V with other Hysterothylacium V and with H. deardorffoverstreetorum, although this is a species inquirenda. Haplotypes for Hysterothylacium type X found in the present study formed a monophyletic group with other Hysterothylacium X, H. amoyense, and H. zhoushanense. Through this study, new hosts and localities were registered for Hysterothylacium type V and Hysterothylacium type X.

Abstract
Recent examinations of anisakid nematodes (Anisakidae) from marine fishes off New Caledonia, collected in the years 2003–2008, revealed the presence of the following five new species of Raphidascaris Railliet et Henry, 1915, all belonging to the subgenus Ichthyascaris Wu, 1949: Raphidascaris (Ichthyascaris) spinicauda n. sp. from the redbelly yellowtail fusilier Caesio cuning (Caesionidae, Perciformes); Raphidascaris (Ichthyascaris) fasciati n. sp. from the blacktip grouper Epinephelus fasciatus (Serranidae, Perciformes); Raphidascaris (Ichthyascaris) nudicauda n. sp. from the brushtooth lizardfish Saurida undosquamis (Synodontidae, Aulopiformes); Raphidascaris (Ichthyascaris) euani n. sp. from the Japanese large-eye bream Gymnocranius euanus (Lethrinidae, Perciformes); and Raphidascaris (Ichthyascaris) elopsis n. sp. from the Hawaiian ladyfish Elops hawaiensis (Elopidae, Elopiformes). An additional two congeneric species, R. (I.) etelidis Moravec et Justine, 2012 and R. (I.) sillagoides (Bruce, 1990) were found in the deep-water red snapper Etelis carbunculus (new host record) and the deepwater longtail red snapper Etelis coruscans (both Lutjanidae, Perciformes), and the silver sillago Sillago sihama (Sillaginidae, Perciformes) (new host and geographical records), respectively. Two unidentified congeneric species, Raphidascaris (Ichthyascaris) sp. 1 from the trumpet emperor Lethrinus miniatus (Lethrinidae, Perciformes) and Raphidascaris (Ichthyascaris) sp. 2 from the white-spotted puffer Arothron hispidus (Tetraodontidae, Tetraodontiformes) were recorded. Moreover, two species of Hysterothylacium Ward et Magath, 1917, H. alatum Moravec et Justine, 2015 and H. epinepheli (Yamaguti, 1941), were found in the leopard coralgrouper Plectropomus leopardus (type host) and the highfin grouper Epinephelus maculatus (new host) (both Serranidae, Perciformes), respectively. This is the second finding of H. epinepheli since its original description in Japan 79 years ago. Most species are described based on light and electron microscopical studies.

Abstract
The striped red mullet Mullus surmuletus (Linnaeus, 1758) (Perciformis: Mullidae) has a high commercial value and therewithal is a common demersal fish of the Mediterranean Sea, therefore studying the helminth parasites of this fish is required. Anisakids nematodes are common parasites of animals including human causing economic losses and different parasitic diseases. During the present study, the nematode Dujardinascaris spp. (Anisakidae) was described from the body cavity and small intestine of Mullus surmuletus in the Alexandria, Mediterranean Sea, Egypt as new host and new geographical record. Forty-five (37.5%) fish out of (120) were found infected by the parasite. The morphological features of the collected nematode were investigated by both light and scanning electron microscopy. The study revealed that the specimens were characterized from other species of the genus by the presence of two large lateral pouches attached to each cephalic lip, the different large-sized papillae on the cephalic region and on the dorsal surface of the nematode cuticle.

Abstract
Genetic and morphological variations in two component populations of Raphidascaris (Sprentascaris) lanfrediae collected in the intestine of Geophagus argyrosticus and G. proximus (Cichlidae) from States of Pará and Amapá, Brazil, respectively, were explored for the first time. A phylogenetic study including two genes (18S and 28S of the rDNA) plus morphological and life history traits of "anisakid-related" nematodes (Anisakidae, Raphidascarididae) was also performed in order to clarify taxonomic and systematic issues related to these taxa. Gene alignments were subjected to maximum likelihood (ML) and Bayesian Inference (BI), and combined data of the genetic and morphological datasets was subjected to maximum parsimony (MP) analysis. Despite of the subtle differences in the morphology (mainly in male caudal papillae) and morphometry between specimens of R. (S.) lanfrediae from the two different hosts and from the type material of the species, no genetic variation was found among representatives of the newly collected material. This find may represent an example of gene-environment interactions, similar to that recently observed for Raphidascaroides brasiliensis. Phylogenetic reconstructions indicated the paraphyly of Anisakidae represented by two subfamilies, i.e., Anisakinae and Contracaecinae and the monophyly of Raphidascarididae. Analysis of the combined datasets revealed that some morphological traits may represent apomorphic characters of Raphidascarididae and Anisakidae, whereas others are highly homoplastic and some may be interpreted with careful to avoid errors. The results support the premise that taxonomists should consider Anisakidae and Raphidascarididae as separate families, and only two subfamilies of Anisakidae, i.e., Anisakinae and Contracaecinae.

ACTA ACUST UNITED AC 2016; 23:40.

Abstract
Parasitological examination of marine perciform fishes belonging to four species of Carangoides, i.e. C. chrysophrys, C. dinema, C. fulvoguttatus and C. hedlandensis (Carangidae), from off New Caledonia revealed the presence of nematodes. The identification of carangids was confirmed by barcoding of the COI gene. The eight nematode species found were: Capillariidae gen. sp. (females), Cucullanus bulbosus (Lane, 1916) (male and females), Hysterothylacium sp. third-stage larvae, Raphidascaris (Ichthyascaris) sp. (female and larvae), Terranova sp. third-stage larvae, Philometra dispar n. sp. (male), Camallanus carangis Olsen, 1954 (females) and Johnstonmawsonia sp. (female). The new species P. dispar from the abdominal cavity of C. dinema is mainly characterised by the body length (5.14 mm), the lengths of markedly unequal spicules (163 and 96 μm) and gubernaculum (102 μm long) provided with a dorsal protuberance and a small, reflexed dorsal barb on its posterior portion. The finding of C. bulbosus represents the first record of this parasite a century after its discovery; the first study of this species by scanning electron microscopy (SEM) enabled detailed redescription. The finding of Johnstonmawsonia sp. in C. fulvoguttatus is the first record of a rhabdochonid nematode from a host belonging to the Carangidae family. Johnstonmawsonia africana Moravec & Puylaert, 1970 and J. campanae Puylaert, 1973 are transferred to Prosungulonema Roytman, 1963 as P. africanum (Moravec & Puylaert, 1970) comb. n. and P. campanae (Puylaert, 1973) n. comb.

Abstract
Hagfish are the most primitive craniates and scavengers, feeding on dead organisms as well as fish and invertebrates. Hagfish play an important ecological role in recycling nutrients, helping to recycle biomass from the upper water column. We investigated 265 specimens of four hagfish species, including Eptatretus burgeri, Eptatretus yangi, Eptatretus sheni and Eptatretus taiwanae from northeastern Taiwanese waters of the northwestern Pacific from November 2013 to June 2014. Eight species of Anisakid nematodes were identified: Anisakis pegreffii, Anisakis simplex s.s., a recombinant genotype of A. pegreffii and A. simplex s.s., Anisakis typica, Anisakis sp., Anisakis brevispiculata, Anisakis physeteris and Hysterothylacium amoyense. Anisakis sp. and H. amoyense represented new locality records. The prevalence, mean intensity and mean abundance of anisakid nematodes for all specimens were 21.51%, 5.39 larvae per fish and 1.16 larvae per fish, respectively. A. pegreffii was the most frequent species in E. burgeri, E. yangi and E. taiwanae, whereas in E. sheni, the dominant species was Anisakis sp. The number of nematodes was significantly related to the host length for E. burgeri and E. sheni, but was not related to the sex of the four hagfish species. This report of scavenging hagfish infected with Anisakid larvae suggests hagfish as a transport/paratenic host between cetaceans and piscivores. Anisakiasis may be caused by the consumption of infectious third-stage larvae in raw or undercooked hagfish.
