new species of Stephanostomum Looss, 1899 (Digenea, Acanthocolpidae) with abizarre oral sucker: S-adlardi sp nov from the common coral trout Plectropomus leopardus (Lacepede,1802) (Perciformes, Serranidae) from Lizard Island, Great Barrier Reef
A new species of Acanthocolpidae, Stephanostomum adlardi is described fromthe serranid Plectropomus leopardus from Lizard Island in the northern Great Barrier Reef. Itdiffers from all previously described acanthocolpids in the structure of the oral sucker which isextended into dorsal and ventral lobes each bearing a row of spines. A phylogenetic tree estimatedfrom combined nuclear small and partial large ribosomal RNA gene sequences shows that, despite theunusual oral sucker structure, the species is a true member of the genus Stephanostomum. Themolecular results also suggest that Monostephanostomum nolani is derived from within Stephanostomum.
