Specimens of the physalopterid nematode Proleptus obtusus Dujardin, 1845 collected from the intestine of the puffadder shyshark Haploblepharus edwardsii (Voigt) off De Hoop Nature Reserve, Cape Province, South Africa, made possible the redescription this little-known species. The SEM study of the cephalic end revealed the presence of circumoral denticles and some oral structures (lateral transverse mounds on the inner surface of pseudolabia, dorsolateral and ventrolateral band-like formations… 
Heliconema longissimum (Ortlepp, 1923) (Nematoda: Physalopteridae) from Pisodonophis boro (Teleostei: Ophichthidae) in Thailand, with remarks on the taxonomy of the Proleptinae Schulz, 1927
The present finding of H. longissimum in Pisodonophis boro represents the first host record and the first record of this nematode from Thailand.
Infection of the lesser spotted dogfish with Proleptus obtusus Dujardin, 1845 (Nematoda: Spirurida) reflects ontogenetic feeding behaviour and seasonal differences in prey availability
The results indicate that parasite burden is best explained by the interaction between ontogenetic differences in foraging behaviour of the lesser spotted dogfish and seasonal differences in prey availability.
Ultrastructural characterization of male and female Physaloptera rara (Spirurida: Physalopteridae): feline stomach worms
The morphological features of adult P. rara, found in dogs, coyotes, raccoons, wolves, foxes, cats, and bobcats, are reported using scanning electron microscopy.
Metazoan parasites of the small-spotted catshark (Scyliorhinus canicula, Linnaeus 1758) caught off the Mediterranean Sea
The goal of this study was to investigate the metazoan fauna of S. canicula caught in the Mediterranean Sea and found the high prevalence of P. obtusus observed in the present study is similar to those observed in Ireland, United Kingdom and Spain.
Parasites of Scyliorhinus canicula (Linnaeus, 1758) in the north-eastern Aegean Sea
The present study provided a first record of Neoalbionella sp.
Scanning electron microscopy observations of the hedgehog stomach worm, Physaloptera clausa (Spirurida: Physalopteridae)
The present SEM study provides the first in-depth morphological characterization of adult P. clausa, and highlights similarities and differences with P. bispiculata P. herthameyerae, Heliconema longissimum and Turgida turgida.
Composition and seasonal dynamics of the parasite communities of Scyliorhinus canicula (L., 1758) and Galeus melastomus Rafinesque, 1810 (Elasmobranchii) from the NW Mediterranean Sea in relation to host biology and ecological features
The parasite communities of Scyliorhinus canicula and Galeus melastomus are studied for the first time in the Mediterranean and monogenean parasites were associated to high turbidity and temperature levels, which are known to enhance monogenan infection and reproductive success.
Parasites of cartilaginous fishes (Chondrichthyes) in South Africa - a neglected field of marine science.
This review summarises information on all groups of parasites of chondrichthyan hosts and demonstrates the current knowledge of chONDRichthyan parasites in South Africa.

It is apparent that their present classification system does not reflect phylogenetic relationships and a taxonomic revision of this nematode group, based on detailed morphological (including SEM and TEM), life history and molecular studies of individual species, is quite necessary.
Marine Fish Parasitology in South Africa: History of Discovery and Future Direction
Almost 200 years have passed since the first description of a marine fish parasite from South Africa. It is therefore an opportune time to look back, take stock of and reflect on the history of


Proleptusmackenzieisp.n. (Nematoda, Spirurida) from Raja fyllae in the Barents Sea
Previous work on species of Proleptus Dujardin, 1845 and related genera is briefly reviewed. Proleptus mackenziei sp.n. is described and figured. P. mackenziei is close to P. obtusus, P. acutus and
Proleptus acutus (Nematoda: Physalopteridae), a parasite from an Argentinian skate, Sympterygia bonapartei (Pisces: Rajidae).

Sympterygia bonapartei is a new host and is endemic to southern Brazil, Uruguay, and Argentina and constitutes the first finding in Argentinian waters.
Heliconema brooksi n. sp. (Nematoda: Physalopteridae) from the ophichthid eel Ophichthus gomesi in the Gulf of Mexico.
Heliconema brooksi n. sp. is described from the shrimp eel, Ophichthus gomesi, in Mississippi Sound. This species is distinguished from other members of the genus by possessing in the male 40 or more
Proleptus niedmanni sp.n. (Nematoda: spiruroidea) from a shark, Schoroederichthys chilensis (Guichenot), in southern Chile
A new species of shark from a shark, Schoroederichthys chilensis, in southern Chile is described and compared with other species of the genus Proleptus Dujardin and distinguished from them by the number and the distribution of papillae of the caudal alae.
Nova contribuição para o estudo dos nematódeos de peixes do Oceano Atlântico: Costa Continental Portuguesa e Costa do Norte da Africa
In an examination of 21 fishes from Atlantic Ocean - Continental Portuguese Coast and North African Coast, 6 were parasited by nematodes and Contracaecum magnum is for the first time reported infecting both Solea solea and Batrachoides didactylus.
