Phyllobothrium riseri n. sp. is described from the leopard shark Triakis semifasciata collected from Californian coastal waters. The descriptions of the type-species, Phyllobothrium lactuca, and P. serratum are amended. P. serratum differs from P. lactuca in having wider mature segments, a larger apical sucker and a greater number of testes in cross-section. P. riseri differs from P. lactuca in being shorter, having a narrower cirrus-sac and having a smaller ovicapt. It differs from P. serratum… 

Three new species of Anthocephalum Linton, 1890 (Cestoda: Tetraphyllidea) from dasyatid stingrays of the Gulf of California

The phylogenetic status of Anthocephalum species in relationship to Rhinebothroides Mayes, Brooks & Thorson, 1981, Pararhineothroides Zamparo, Brooks& Barriga, 1999 and other rhinebothriin taxa is discussed.

Two new species of Duplicibothrium Williams & Campbell, 1978 (Tetraphyllidea: Serendipidae) from the Pacific cownose ray Rhinoptera steindachneri

Systematic information gained from the study of these two new species supports the monophyly of the tetraphyllidean family Serendipidae and suggests that Duplicibothrium shares a phylogenetic heritage with species in the genera Glyphobothrium and Seredip, taxa that are also parasitic in cownose rays.

Anthobothrium lesteri n. sp. (Cestoda: Tetraphyllidea) in Carcharhinus melanopterus from Heron Island, Australia, with comments on its site, mode of attachment, reproductive strategy and membership of the genus

A combination of characters, namely the number of testes, a weakly laciniate strobila and mature proglottis which is conspicuously longer than wide distinguishes it from other species that appear to be consistent with van Beneden's original concept of Anthobothrium.

Cairaeanthus gen. n. (Cestoda, Rhinebothriidea), with the Description of Two New Species from Dasyatis pastinaca in the Black Sea and the Sea of Azov

The new genus, Cairaeanthus Kornyushin et Polyakova, is established and can be distinguished from Rhinebothrium Linton, 1890 by the absence of facial loculi on the bothridia and by numerous vitelline follicles, stopping at the anterior margin of the ovary.

Orectolobicestus n. g. (Cestoda: Tetraphyllidea), with the description of five new species and the transfer of Phyllobothrium chiloscyllii to the new genus

This genus is erected for six cestode species parasitising bamboo sharks (Orectolobiformes: Chiloscyllium) and most closely resembles Paraorygmatobothrium and Ruhnkecestus in its vitelline fields being interrupted by the ovary and the possession of a scutellate neck.

Phyllobothrium squali Yamaguti, 1952 (Tetraphyllidea, Phyllobothriidae): redescription and first record in the Black Sea

Phyllobothrium squali Yamaguti, 1952 is redescribed and illustrated on the basis of the holotype from Squalus acanthias from Japanese waters and specimens from the same host off the Bulgarian Black

Morphological and molecular characterization of tetraphyllidean merocercoids (Platyhelminthes: Cestoda) of striped dolphins (Stenella coeruleoalba) from the Western Mediterranean

Intra- and inter-sample variability in the morphology of the apical organ suggested that it degenerates during larval development, and suggests that each type of tetraphyllidean merocercoids may represent a single species, contrary to previous speculations based on morphological data.

Parasite communities of two sharks, Etmopterus granulosus (Squaliformes) and Schroederichthys bivius (Carcharhiniformes), from Southern Chile

The purpose of this study was to analyze the parasite community of two shark species from Southern Chile considering that the shark-parasite association in the area is poorly known. A total of 24

Intestinal helminth fauna of the shortfin mako Isurus oxyrinchus (Elasmobranchii: Lamnidae) in the northeast Atlantic Ocean.

The results conform to previous studies on oceanic predators that have hypothesized that these hosts should have depauperate and unpredictable helminth infracommunities because oceanic conditions hamper parasite transmission, but mean species richness and mean total abundance of cestodes of shortfin mako and other oceanic sharks did not significantly differ from those of elasmobranchs from other habitats.

On the phylogenetic relationships among tetraphyllidean, lecanicephalidean and diphyllidean tapeworm genera

The tetraphyllideans, lecanicephalideans and proteocephalideans are more closely related to each other than they are to the diphyllideans or the trypanorhynchs, and some aspects of the classification of the lecanICEphalidean and tet graphyllidean taxa require revision.



Paraorygmatobothrium barberi n. g., n. sp. (Cestoda: Tetraphyllidea), with amended descriptions of two species transferred to the genus

Two of the species placed in the new genus have microtriches resembling an “ear of corn” on the distal bothridial surface, which potentially indicates a systematic relationship between members of Paraorygmatobothrium and these two species.

Resurrection of Anthocephalum Linton, 1890 (Cestoda: Tetraphyllidea) and taxonomic information on five proposed members

The generic diagnosis of Anthocephalum is emended to include information from A. gracile, A. centrurum and the three new species, whose proximal bothridial surfaces are covered with short, stumpy microtiches and thick, spiniform microtriches, and their cirri were found to be armed with spiniformmicrotriche, rather than spines.

The Taxonomy, Ecology and Host-Specificity of Some Phyllobothriidae (Cestoda: Tetraphyllidea), A Critical Revision of Phyllobothrium Beneden, 1849 and Comments on Some Allied Genera

Two new and twelve little known species of Phyllobothrium or of allied genera, mainly from elasmobranchs and teleosts caught off the British Isles, have been investigated and the genus is revised for the first time.

A new species of Clistobothrium (Cestoda : Tetraphyllidea), with an evaluation of the systematic status of the genus

Clistobothrium montaukensis n. sp. is described from the shorfin mako shark, Isurus oxyrinchus. Based on shared characters from the scolex and segment, Phyllobothrium tumidum is transferred to the

A Monograph on the Tetraphyllidea: with Notes on related Cestodes.

The Cestoda have superficially a very considerable resemblance to each other and an elaborate technique is necessary before their internal anatomy can be satisfactorily studied, but knowledge of the whole group is in a very chaotic condition indeed.
