| branchotenthes octohamatus sp. n. (monogenea: hexabothriidae) from the gills of the southern fiddler ray, trygonorrhina fasciata (rhinobatidae) in south australia: description of adult and larva. | branchotenthes octohamatus sp. n. (monogenea: hexabothriidae) is described from the gills of the southern fiddler ray, trygonorrhina fasciata müller et henle (elasmobranchii: rhinobatidae), off adelaide, south australia. it is distinguished from the type species, branchotenthes robinoverstreeti bullard et dippenaar, 2003, by producing eggs that are joined end to end forming a chain, in the morphology of the male copulatory organ that has a pronounced constriction in duct diameter between proxima ... | 2005 | 16270803 |
| three unrelated species, 3 sites, same host--monogenean parasites of the southern fiddler ray, trygonorrhina fasciata, in south australia: egg hatching strategies and larval behaviour. | the southern fiddler ray, trygonorrhina fasciata (rhinobatidae), is parasitized by 3 monogenean (platyhelminth) species from 3 families on 3 different sites of the host: calicotyle australis (monocotylidae) from the cloaca, pseudoleptobothrium aptychotremae (microbothriidae) from the skin and branchotenthes octohamatus (hexabothriidae) from the gills. cues that promote egg hatching were investigated for each species and the behaviour of their larvae was also documented. eggs were laid by parasit ... | 2006 | 16563201 |
| experimental infections, using a fluorescent marker, of two elasmobranch species by unciliated larvae of branchotenthes octohamatus (monogenea: hexabothriidae): invasion route, host specificity and post-larval development. | the infection biology of branchotenthes octohamatus (monogenea: hexabothriidae) from the gills of the southern fiddler ray, trygonorrhina fasciata (rhinobatidae), was studied using the fluorescent dye, 5(6)-carboxyfluorescein diacetate n-succinimidyl ester (cfse). this is the first use of this technique on a monogenean species with unciliated larvae and the first for any monogenean larva infecting an elasmobranch host. cfse-labelled post-larvae were recovered from gills of t. fasciata within 30 ... | 2007 | 17381886 |
| comparative phylogeography reveals host generalists, specialists and cryptic diversity: hexabothriid, microbothriid and monocotylid monogeneans from rhinobatid rays in southern australia. | the phylogeography and host specificity of three monogenean species infecting different sites on the southern fiddler ray, trygonorrhina fasciata (rhinobatidae) in south australia (sa) were studied: branchotenthes octohamatus (hexabothriidae: gills), calicotyle australis (monocotylidae: cloaca) and pseudoleptobothrium aptychotremae (microbothriidae: skin). five rhinobatid species (aptychotrema vincentiana, t. fasciata, trygonorrhina sp. a, aptychotrema rostrata and rhinobatos typus) with distrib ... | 2008 | 18621052 |
