| Abstract: | Omeipsis is an endemic trilobite genus typical of the Ordovician Yangtze Block. It occurs only rarely in the Arenig of the Ordovician in association with inner shelf clastic facies. The genus was erected by Kobayashi (1951) on the basis of Acidaspis huangi Sun, 1931. Since then, only one more species, O. zhenxiongensis Luo, has further been referred to it. |
