本文描述了窄唇纲苔藓动物的一个新种Ｃａｓｉａｎｏｐｏｒａｈｅｉｓｐ．ｎｏｖ．，此新种发现于我国滇西北宁蒗彝族自治县松桂组１５层（菊石Ｍａｌａｙｉｔｅｓ－Ｐｓｅｕｄｏｃａｒｄｉｏｃｅｒａｓ带），是迄今已知的全球三叠纪泡孔类的一个最新代表。重新确定了Ｃａｓｉａｎｏｐｏｒａ属（卡尼中期－诺利早期）的分类位置，它和Ｃｙｓｔｉｔｒｙｐａ属（卡尼早期）都归入Ｆｉｓｔｕｌｉｐｏｒｉｄａｅ科。这两个三叠纪的属，与古生代和古生代后的一些泡孔类的种系发生关系的初步探讨表明，所有古生代后的窄唇纲的各个目（除环口目外），可能都是从同一演化根系上发展而来的。
This article describes a new species of the genus Casianoporaheisp from the family Bryuga. nov This new species was found in the 15th layer of the Songui Formation (Malayites-Pseudocardioceras zone) in the Ninglang Yi Autonomous County, northwestern Yunnan, China. It is a newest representative of the known Triassic cell types in the world to date. The classification of the genus Casianopora (early period of Cannari-Noli) was re-established and belongs to the family Fistuliporidae, both genus Cystitrypa (early Kani). The preliminary study of the relationship between the two Triassic genera and the Paleozoic and Paleozoic cell families shows that all the Palaeozoic Narrows are all Evolved from the same evolution root system.
