(cestoda: lecanicephalidea) from the sharkray, rhina ancylostoma bloch & schneider (elasmobranchii: rhinopristiformes), from northern australia. | a new genus and species of lecanicephalidean cestode, stoibocephalum arafurense n. gen., n. sp., is described from the sharkray, rhina ancylostoma bloch & schneider, off northern australia. stoibocephalum arafurense n. gen., n. sp. is apolytic, and possesses a large, muscular, retractable apical organ, 3 pairs of excretory vessels, and testes in several columns and layers. the presence of 3 pairs of excretory vessels distinguishes this new genus from all other valid lecanicephalidean genera, exc ... | 2013 | 26176156 |
| branchotenthes robinoverstreeti n. gen. and n. sp. (monogenea: hexabothriidae) from gill filaments of the bowmouth guitarfish, rhina ancylostoma (rhynchobatidae), in the indian ocean. | branchotenthes robinoverstreeti n. gen. and n. ap. (monogenea: hexabothriidae) infects the gill filaments of the bowmouth guitarfish, rhina ancylostoma bloch and schneider, 1801 (rhynchobatidae) in the southwest indian ocean off trafalgar, south africa. the new species is most easily distinguished from other hexabothriids by the combination of having a symmetrical haptor, c-shaped haptoral sucker sclerites that are approximately equal in size, haptoral suckers that are equal in size and arranged ... | 2003 | 12880262 |
