摘要：
Four new fossil species of the family Ommatidae from the Yixian Formation of western Liaoning,China are described. 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 Bro- chocoleus.The relationship between the genus Cionocoleus and the extant family Crowsoniellidae is briefly discussed.
