Abstract:A new taxon of genus Paradiplozoon (Monogenea: Diplozoidae) was described as a new species Paradiplozoon bannaensis sp.nov. from the gills of host Sikukia flavicaudata (Cyprinidae), which was collected from the Jinghong drainage area of Lancang River, Xishaungbanna (22°0′28″N100°47′43″E). The mean total body length of Paradiplozoon bannaensis is about 2.539 mm, the mean total body width is about0.143 mm, the anterior part of body length is1.500 mm, and the posterior part of body length is about0.894 mm. Paradiplozoon bannaensis has a pair of half-moon shape oral sucker. The ovary is oval shape and located at the beginning of the posterior part of body. One testis with long leave shape was observed at posterior of ovary. Paradiplozoon bannaensis is distinctly distinguished from all the recorded Paradiplozoon species by the combination of morphological characteristics, including disk-like haptor, clamp and central hook morphology, intestine shape and body size of specimens. In view of the host-specificity and coevolution between monogenea-fish, and Sikukia flavicaudata is endemic and indigene fish of Lancang River, we consider Paradiplozoon bannaensis is a scientific undescribed species. The specimens were conserved in the School of Life Sciences of Yunnan Normal University.
