[摘要]
文中通过对Ushbaspis hubeiensis (Lin,1978)新材料的研究,对该种三叶虫躯体构造特征做了重要补充,使人们对它有更全面的认识,也将为今后进一步对乌什巴盾壳虫类(ushbaspid) 三叶虫的分类、系统演化的研究以及对寒武纪第二世生物地层划分,提供一些重要依据。文中还就张文堂等(1980)将采自贵州湄潭的Kepingaspis sp.标本鉴定为Metaredlichioides constrictus Qian and Yao,1974提出质疑。

[Abstract]
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.
