中文摘要:

文中通过对己发表的Abadiellidae科三叶虫中的两个亚科20个属(亚属)、种(包括16个属、1个亚属和3个种)模式标本的头盖特征而进行Q型聚类分析,并结合传统定性分析后,认为Parabadiella Chang,1966,Parabadiella(Danangouia)Chen,1985和Guangyuanaspis Chang and Qian,1974均是Abadiella Hupe,1953的晚出异名。Wenganaspis Yin in Yin and Li,1978,Sardaspis Brasier,1976分别为Kepingaspis T.Chang,1965和Yorkella Kobayashi,1942的晚出异名。Chaoaspis Chang,1966和Kuanyangia(Sapushania)Chang,1966均为Kuanyangia Hupe,1953的晚出异名。Jell(1990)和Opik(1975)分别鉴定的Abadiella huoi(Chang,1966)和Dolerolenus(?)sp.nov.,前者应为Abadiella Hupe,1953的一个新种——Abadiella jelli(Chang,2001),后者应归入Abadiella euryoptilos(Paterson and Brock,2007)。还认为Malongocephalus Zhang and Lin,1980和SibiriaspisR epina,1960两属应归属Wutingaspinae Hupe,1953亚科。

英文摘要:

In the present paper, the method of "Q-mode cluster analysis" has been used in the taxonomic study of cranidia which belongs to 20 different genera (subgenera) and species of abadiellid trilobite in the traditional Early Cambrian. The statistical measurement of similarity is the increments of sum of error squares (AE). Twenty-three variables are selected, of which fourteen are quantitative ratio values, while the remaining nine are qualitative data. The resemblance relation matrices of all specimens are {ormed through calculation of the increments of sum of error squares between those specimens (see text-table Ⅰ ). Finally the two-dimensional dendrogram is drawn by stepwise calculation (see text-fig. 1). The dendrogram (text-fig. 1) is divided into two groups by the association line having a value 12. 000 (a-ap) of the increments of sum of error squares. They correspond to: A group (=Subfamily Abadiellinae) containing 6 genera, 1 subgenus and 2 species: Shaanxia Zhang and Lin, 1980 (16), Lunolenus Sdzuy, 1961 (10), Guangyuanaspis Chang and Qian, 1974 (6), Parabadiella huoi (Chang, 1966) (13), Dolerolenus (?) sp. nov. Opik, 1975 (5), Abadiella Hup6, 1953 (1), Abadiella officer Jago, Lin and Dunster, 2002 (2), Parabadiella Zhang, 1966 (12) and Parabadiella (Danangouia) Chen, 1985 (14). B group (= Subfamily Wutingaspinae)-containing 10 genera and 1 subgenus. Chengjiangaspis Zhang and Lin, 1980 (4), Sardaspis Brasier,1976 (15), Yorkella Kobayashi, 1942 (20), Chaoaspis Chang, 1966 (3), Kuanyangia Hupe, 1953 (8), Kuanyangia ( Sapushania ) Chang, 1966 (9), Sibiriaspis Repina, 1960 (17), Malongocephalus Zhang and Lin, 1980 (11), Wutingaspis Kobayashi, 1944 (19), Kepingaspis T. Chang, 1965 (7) and Wenganaspis Yin, 1978 (18). Through the application of combined cluster analysis with traditional qualitative analysis in the study of 20 genera (subgenera, species) of abadiel- li
