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 Brochocolemi: 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.
