Abstract

Monocotyle luquei n. sp. (Monogenea: Monocotylidae) was described from gills of diamond stingray Dasyatis dipterura (Jordan and Gilbert, 1880) (Dasyatidae) off Peru. The new species can be differentiated from the other species of the genus by the combination of the following characteristics: (1) accessory sclerites on the dorsal posterior surface of the body absent, (2) only one testis is present, (3) 1–2 loops in the copulatory organ, (4) the male copulatory organ with a sclerotized accessory piece, (5) shape of five sclerites in marginal papillae, (6) size of anchor and (7) posterolateral septa bifurcated. This is the first record of species of Monocotyle Taschenberg, 1878 from the southern Pacific.
