摘　　要：Pilophyllia Ge et Y,1974具有典型的包珊瑚型隔壁,是包珊瑚科的主要分子。该属广泛分布于上扬子区志留纪兰多维列世地层。首次对采自贵州石阡中兰多维列世(Llandovery)爱隆期(Aeronian)香树园组和雷家屯组的大量Pilophyllia Ge et Y,1974标本进行详细研究,经鉴定,共计有9种,其中包括6新种,1未定种,它们是:Pilophyllia simplex Chen,1986,P.fenggangensis Ge et Y,1974,P.vesiculosa Tang sp.nov.,P.conica Tang sp.nov.,P.ultimuma Tang sp.nov.,P.stylaris Tangsp.nov.,P.raritabulata Tangsp.nov.,P.lei-jiatunensis Tang sp.nov.,Pilophyllia sp.。此外,根据新的研究材料补充和修订Pilophyllia部分属征,并将石阡地区香树园组和雷家屯组的Pilophyllia种群特征与川北、陕南宁强组(Telychian阶)的进行比较。Rugosan genus Pilophyllia Ge et Yü, 1974 possesses typical amplexoid septa belonging to the Family Amplexidae. This genus is widespread in Llandovery strata in the upper Yangtze region, China. Numerous specimens of Pilophyllia collected from the Xiangshuyuan and Leijiatun formations （Aeronian） in the Shiqian area, northeastern Guizhou are studied in the present paper. The diagnosis of this genus is emended, and its geological distribution are discussed in detail. Nine species are described and illustrated here for the first time. Among them, 6 species are new. They are： Pilophyllia vesiculosa Tang sp. nov. , P. conica Tang sp. nov., P. ultirnurna Tang sp. nov., P. stylaris Tang sp. nov. , P. raritabulata Tang sp. nov. and P. leijiatunensis Tang sp. nov. In addition, the characteristics of the Pilophyllia species populations from the Xiangshuyuan and Leijiatun formations in the Shiqian district are briefly discussed and compared with those of the Ningqiang Formation（Telychian）, southern Shaanxi and northern Sichuan.
