摘　　要：In this paper one new genus and one new species of fossil ommatid, Odontomrna trachylaena gen, et sp. nov., is described and illustrated from the Late Jurassic or Early Cretaceous Yixian Formation of western Liaoning, China. Based on wide epipleural space of elytron with several rows of cells, the new taxa is attributed to tribe Brochocoleini of Ommatidae and compared with genus Brochocoleus. Due to the fact that most other Chinese Mesozoic ommatids are not complete, the complete preservation of the new specimens reported here enabled us to determine the characteristics of the body of these ancient ommatid. Moreover, based on the well-preserved individual of this new genus, we may suppose the affinities of the new species with extant and extinct groups.在这糊一个新类和石块 ommatid 的一新种， Odontomma trachylaena 情报。et sp。nov，从迟了的侏罗记或西方的辽宁的早白垩纪 Yixian 形成被描述并且说明，中国。与几排细胞基于 elytron 的宽 epipleural 空间，新税一是归因于 Ommatidae 并且与类 Brochocoleus 相比的部落 Brochocoleini。由于大多数另外的中国中生代 ommatids 不是完全的事实，这里报导的新标本的完全的保藏使我们能决定这些古老的 ommatid 的身体的特征。而且基于这个新类的保存得很好的个人，我们可以与现存、绝灭的组一起建议新种类的亲密关系。
