Extract

Gemmaecaputia australis sp. nov. and Vallisiopsis australis sp. nov. are described from the gills of the striped barracuda, Sphyraena obtusata Cuvier & Valenciennes. G. australis differs from all other species in the genus by the presence of a bifurcated copulation canal and small spines on the penis. V. australis differs from the other species in the genus because of the presence of an unsclerotised penis and seven opisthaptoral clamps. The method of adhesion of V. australis is described and an account given of its adhesion on the host gills.
