ON NUMERICAL TAXONOMY OF FIFTEEN SPECIES IN PHYLLODISTOMUM

LIU JIA-YWG LANG Suo(Department of Biology, East China Normal University, Shanghai 200062)  
The fifteen species of phyllodistomes from fishes in China are studied with the hierarchical cluster analysis and principal components analysis (PCA), based on twelve structural characters of adults commonly used in traditional classification of genus Phyllodistomum.The clustering analysis of Euclidean taxonomic distance using different methods have got eight dendrograms. In general these phenograms show similar results, that is, the fifteen species of phyllodistomes are basically clustered into two sub-groups. Sub-group Ⅰ consists of three sections: There are two species (P. sinipercae Long et Wai, 1958 and P. sinense Wu, 1937) in section-1, three species (P. anguilae Long et Wai, 1958, P. lesteri Wu, 1938 and P. mingensis Tang, 1985) in section-2, and two species (P. hemiculteri Wang, 1984, and P. plagiognathops Wang, 1984) in section-3. Sub-group Ⅱ also consists of three sections: There are three species (P. carassii Long et Wai, 1958, P. bai Long et Wai, 1958 and P. pawlovskii Zmeev, 1936) in section-4, two species (P. parasiluri Yamaguti, 1934 and P. clariasi Lai et al., 1985) in section-5, and two species (P. sanyangense Wang, 1982 and P. serrispatula Chin, 1963) in section-6. The fourteen species of phyllodistomes are digeneans from freshwater fish-es, and P. pearsei Holl, 1929 is the one from marine fish. It seems that the marine species is a relatively independent branch in the hierarchical dendrograms, however it is more related to P. siniperae, which is clustered in sub-group Ⅰ. The sub-group Ⅰ (seven freshwater species and one marine species) and the sub-group Ⅱ(another seven freshwater species) correspond with two subgenera, Phyllodistomum Pigulevsky, 1952 and Catoptroides Odhner, 1902 respectively.The ordination of the structural characters of adult phyllodistomes obtained by PCA fur- ther demonstrates the same result mentioned above. The seven freshwater species clustered in sub-group Ⅰ are located mostly within the second quadrant in the ordination of the two di-mentions (Ⅰ and Ⅱ principal component). Another seven freshwater species clustered in sub-group Ⅱ are located within the fourth quadrant and a marine species at a corner of the first. Therefore, we believe that it is save and reliable to divide the fifteen Chinese phyllodistomes into the two subgenera.Our PCA indicates that the shape of adult body (body llenght-width ratio and acetabulum relative position), the type of vitellarium (intact and/or branched) and the mutual position of the gonads are the most important characters in taxonomy of the genus Phyllodistomum. The relative position of posterior testis is plssibly a potential diagnostic character available for use in the classification of the phyllodistomes.The assessment of the eight cluster methods used in the present study with cophenetic correlation coefficient shows that unweighted pair-group method arithmatic averages (UPGMA) is one of the best clustering methods (Rcs value is 0.87115) and the distance coefficient can bear more disturbance for the numerical taxonomy of the genus Phyllodistomum.The data provided by Prof. Tang Zhongzhang (1985) and us suggest that three closely related species (P. anguilae, P. lesteri and P. mingenstise) compose a primitive group in genus Phyllodistomum. The problems of systematics in the genus is discussed.
