We describe one new species of Telotrema Ozaki, 1933 from the intestine of an acanthurid fish of the Great Barrier Reef. Telotrema brevicaudatum n. sp. is described from 2 mature specimens from the yellowfin surgeonfish, Acanthurus xanthopterus Valenciennes, 1835 ( Acanthuridae), from waters off Lizard Island, Queensland, Australia. This species is distinguished from the type-species, Telotrema caudatum Ozaki, 1933, by the smaller excretory papilla, the massive pars prostatica, the unipartite, globular seminal vesicle, and the intertesticular position of the ovary. The proposal of a new species of Telotrema necessitates re-examination of the generic diagnosis, and the genus is here redefined in light of the morphology of T. brevicaudatum. Telotrema is distinguished from Gyliauchen Nicoll, 1915 by the possession of a ventral sucker which is larger than the pharynx, a straight or sigmoid oesophagus, an extensive and dense vitellarium, and a distinct excretory papilla. We here recognise 3 species and distinguish them in a key. The biogeographical range for species of Telotrema now includes acanthurid and pomacentrid fishes of the western Pacific Ocean.
