Abstract Oncomegas aetobatidis sp. nov. (Trypanorhyncha: Eutetrarhynchidae) is described from the spiral valve of the dasyatid ray Aetobatus narinari (Euphrasen, 1790) from the Arafura Sea, Northern Territory. The new species is most closely related to O. australiensis Toth, Campbell and Schmidt, 1992 in the number of files of hooks in the metabasal region of the tentacular armature and the presence of post-ovarian testes, but differs in overall dimensions, in the size of the macro-hook in the…

Trypanorhynch cestodes of elasmobranchs from the Persian Gulf.

Within the elasmobranchs, highest prevalence was seen for Otobothrium carcharidis with a maximum intensity of 39 in Rhizoprionodon acutus (Ruppell) and host specificity values were recalculated for Kotorella pronosoma, Pseudogrillotia perelica, Callitetrarhynchus gracilis and ProemotOBothrium southwelli.

Three New Genera and Six New Species of Lecanicephalideans (Cestoda) from Eagle Rays of the Genus Aetomylaeus (Myliobatiformes: Myliobatidae) from Northern Australia and Borneo

New lecanicephalidean cestodes inhabiting the spiral intestine were investigated in 4 of the 6 known species of eagle rays of the genus Aetomylaeus Garman, establishing species of AetOMylaeus as hosts of lecan icephalideans.

Validation of Christianella Guiart, 1931 (Cestoda: Trypanorhyncha) and its taxonomic relationship with Grillotia Guiart, 1927

The subgenus is similar to Grillotia Guiart, 1927 (sensu stricto), having two bothria and an atypical heteroacanthous armature, but differs in having a single row of intercalary hooks, fewer, elongate segments with testes often in longitudinal columns, a distinctive basal armature.

A revision of Oncomegas Dollfus, 1929 (Cestoda: Trypanorhyncha: Eutetrarhynchidae), the description of two new species and comments on its classification

The combination of heteroacanthous typical tentacle armature, two bothridia lacking ciliated pits, presence of prebulbar organs, retractor muscles originating at base of bulbs and posterior ovary warrant the placement of Oncomegas in the Eutetrarhynchidae.
