New Material of Ushbaspis hubeiensis in Zigui, Hubei, China and Its Significance

In the present paper, through the study of new material of Ushbaspis hubeiensis (Lin, 1978), not only gave us more to consider for dorsal exoskeleton of Ushbaspis hubeiensis (Lin, 1978) and also for one nearly complete specimen of Metaredlichioides constrictus Qian and Yao in Zhang et al., 1980 (Zhang et al., 1980, pl. 30, fig. 5) (= Ushbaspis constrictus (Qian and Yao) in Zhang et al., 1997, fig. 277-1c) transferred to Kepingaspis Zhang, 1965 afforded much evidence herein.
