摘　　要：贵州寒武系黔东统都匀阶"清虚洞组"富含三叶虫,其中莱得利基虫主共1属3种:贵州莱得利基虫Redlichia(Redlichia)guizhouensis Zhou,1974、著目莱得利基虫Redlichia(Redlichia)nobilis Walcott,1905及村上翼形莱得利基虫Redlichia(Pteroredlichia)murakamii Resser et Endo in Kobayashi,1935。Redlichia广泛分布于浅水台地区,具有一定的地层意义。"清虚洞组"Redlichia(Redlichia)guizhouensis、Redlichia(Redlichia)nobilis产于"清虚洞组"中上部,Redlichia(Pteroredlichia)murakamii产于"清虚洞组"下部且向下延伸至下伏地层杷榔组中上部。本文基于"清虚洞组"Redlichia形态学的研究,讨论了3个种的种间差异。Redlichiid trilobite are very common in shallow water facies during Early Cambrian and of important stratigraphical significance. Here,three species of Redlichia,Redlichia（ Redlichia） guizhouensis Zhou,1974,Redlichia（ Redlichia） nobilis Walcott,1905 and Redlichia（ Pteroredlichia） murakamii Resser et Endo in Kobayashi,1935,were described from the Cambrian ＂Tsinghsutung Formation＂（ Qiandong Series,Duyun Stage） of eastern Guizhou,Morphological difference between these species were discussed in this paper. Additionally,based on their occurrences,R.（ Redlichia） guizhouensi and R.（ Redlichia） nobilis occur in upper part of the＂Tsinghsutung Formation＂,whereas R.（ Petroredlichia） murakamii ranges from the lower part of＂the Tsinghsutung Formation＂to the middle-upper part of the underlying Balang Formation.
