细齿内齿脂鲤Ma，Shevock & S.根据形态学和分子生物学资料，描述了采自云南亚高山地区的一新种。在形态上，新物种类似于广泛分布的物种E。buseanus，但最显著的区别在于具有显著缩短的刚毛，较小的蒴果和几乎无边界的片层。扫描电子显微镜的图像也显示了孢子表面的复合乳突状突起，这是该新种的特征。基于质体rps 4序列的系统发育分析支持内齿龙属新种的属验证。本文报道了中国大陆新记录种--隐齿藓（Entosthodonphyscomitrioides）。这两个物种的详细描述和插图提供。
Entosthodon elimbatus W.Z. Ma, Shevock & S. He, a new species from a sub-alpine area in Yunnan, China, is described here based on morphological and molecular data. Morphologically, the new species resembles the widespread species E. buseanus, but differs most notably in having significantly shortened setae, smaller capsules and nearly unbordered laminae. Images from the scanning electron microscope also show compound-papillose ornamentation over the spore surface, which is characteristic of this new species. The generic validation of the new species in Entosthodon is supported by a phylogenetic analysis based on the plastid rps4 sequence. Entosthodon physcomitrioides, characterized by its well-developed apophysis and peristome, is confirmed as a new record for mainland China. Detailed descriptions and illustrations for both species are provided.
