Paradiplozoon yunnanensis n. sp. (Monogenea, Diplozoidae) is described from the gills of Sikukia gudgeri Smith, 1931 (Cyprinidae) collected from Jinghong Basin, a tributary of the international Lancang-Mekong River. This is the first diplozoid species from S. gudgeri and its description increases the number of Paradiplozoon species recorded in China to 25. The new species is distinguished from congeners by a combination of morphological and molecular features. The anterior end of the median plate is thickened in the marginal area and a narrow rectangular trapeze spur connects to the anterior jaw through two separate anterior joining sclerites. The posterior end of the median plate sclerite is invaginated with a smooth strip-shaped posterior joining sclerite. Comparison of a newly obtained sequence of rRNA ITS2 with 18 other congeneric sequences from GenBank provides support for separation of the new species.
Résumé
Paradiplozoon yunnanensis n. sp. (Monogenea, Diplozoidae) est décrit des branchies de Sikukia gudgeri Smith, 1931 (Cyprinidae) collecté dans le bassin de Jinghong, un affluent de la rivière internationale Lancang-Mékong. C’est la première espèce de Diplozoidae de S. gudgeri et sa description amène le nombre d’espèces de Paradiplozoon de Chine à 25. La nouvelle espèce se distingue de ses congénères par une combinaison de caractéristiques morphologiques et moléculaires. L’extrémité antérieure de la plaque médiane est épaissie dans la zone marginale et un étroit éperon trapézoïdal rectangulaire se connecte à la mâchoire antérieure par l’intermédiaire de deux sclérites antérieurs séparés. L’extrémité postérieure de la plaque sclérite médiane est invaginée avec un sclérite postérieur lisse en forme de bande. La comparaison de la séquence d’ARNr ITS2 nouvellement obtenue avec 18 autres séquences congénères de GenBank soutient la séparation de la nouvelle espèce.
