摘　　要：在安徽省萧县凤凰山剖面炒米店组中上部(江山阶上部到第十阶)岩层中采得丰富的索克虫科三叶虫标本。共计4属6种(含2新种),包括Eosaukiabella(Walcott,1906)、E.anhuiensissp.nov.、Lophosaukiaorientalis(Kobayashi, 1933)、Prosaukia campe (Walcott, 1905)和P. xiaoxianensis sp. nov.以及Lichengia onigawara Kobayashi,1942。在对属征进行修订与讨论的基础上,通过对比这些属的模式种及其他种,对4个旧种进行了再研究和种征厘定,最后对这6个种的谱系关系开展了简要讨论。Hundreds of specimens of saukiid trilobites were collected from the middle-upper Chaumitien Formation(upper Jiangshanian through Stage 10, Cambrian) at Fenghuangshan Hill in northern Anhui, China. Four genera and six species(including two new species) are described herein: Eosaukia bella(Walcott, 1906), E. anhuiensis sp. nov., Lophosaukia orientalis(Kobayashi, 1933), Prosaukia campe(Walcott, 1905) and P. xiaoxianensis sp. nov., Lichengia onigawara Kobayashi, 1942. After revising and discussing the generic diagnoses, we reexamine and revise the specific diagnoses of the four previously-published species by comparing their type species with others, and briefly discuss the evolutionary relationships among all six species.
