| 摘 要： | 洒普山虫是关杨虫(Kuanyangia)的一个亚属,乃1966年张文堂教授建立的,过去只有两个种:一个种名瘤点洒普山虫Kuanyangia(Sapushania)granulosa Chang,产于云南武定洒普山及狮子山,下寒武统筇竹寺组;另一个种名陕西洒普山虫Kuanyangia(Sapushania)shaanxiensis Zhang et Lin,产于陕西宁强坑家洞,下寒武统郭家坝组。本新种Kuanyangia(Sapushania)bella Chen(sp.nov.),产于云南昆明筇竹寺,下寒武统筇竹寺组。虽然只有一块标本,但标本保存的十分精美完好,与之共生的还有云南云南头虫Yunnanocephalus yunnanensis(Mansuy),产出层位系筇竹寺组的中上部。

| Abstract: | The present paper deals with a new species of trilobite,named Kuanyangia (Sapushania) bella Chen (sp.nov.),in the Lower Cambrian Chiungchussu Formation in Kunming,eastern Yunnan.The specimen is well preserved and occurs in association with Yunnanoce-phalus yunnanensis (Mansuy).It is similar in some respects,Kuanyangia (Sapushawia) granulosa Chang,but different from the latter in absence of preglabellar field,having narrower and longer posterior lateral limbs,a distinct parafrontal band,a triangular preocular limb,a less curved anterior border,a slightly tapering backwards axial lobe of thorax and a sinus at the posterior end of the pygidium. |
