Two of them belong to tribe Brochocoleini： Brochocoleus sulcatus sp. nov. and Brochocoleus angustus sp. nov. The other two refer to tribe Ommatini： Cionocoleus planiusculus sp. nov. and Cionocoleus cervicalis sp. nov. The diagnosis of Brochocoleus and Cionocoleus, respectively, are revised. A preliminary analysis of geographical distribution suggests a possible migration pathway of the genus Brochocoleus. The relationship between the genus Cionocoleus and the extant family Crowsoniellidae is briefly discussed.从西方的辽宁的 Yixian 形成的家庭 Ommatidae 的四新石块种，中国被描述。他们中的二个合适去部落 Brochocoleini：Brochocoleus sulcatus sp。nov。并且 Brochocoleus angustus sp。nov。另外的二指部落 Ommatini：Cionocoleus planiusculus sp。nov。分别地， Brochocoleus 和 Cionocoleus 的诊断被修订。地理分发的初步的分析建议类 Brochocoleus 的一条可能的迁居小径。在类 Cionocoleusand 之间的关系现存家庭 Crowsoniellidae 简短被讨论。
