Polyglyphanodontia is a successful clade of squamates thriving during the Late Cretaceous. They were widely distributed in Asia, North America and possibly some other regions, and are highly diverse in taxonomy, morphology and ecology. Although the clade is better known to have many large herbivores, quite a few small insectivorous species were described from all the main localities where polyglyphanodontian fossils were found. Funiusaurus luanchuanensis from the Upper Cretaceous Qiupa Formation of Henan Province, China is one of them. Previously, it was described based only on a nearly complete but relatively fragmentary skull which therefore provided limited morphological information. Herein we add a great amount of anatomical data of this species based on high-resolution computerized tomography data of a new completely preserved skull and several other cranial and postcranial specimens, especially of the palate, braincase, vertebral column and limbs. The new data of Funiusaurus will help to build a more comprehensive phylogenetic data matrix of Polyglyphanodontia in the future, and further clarify the evolutionary history of body size or diet shift within the clade. 

多凿齿蜥类是一类繁盛于晚白垩世的有鳞类，它们广泛分布于亚洲、北美洲以及其他一些地区，在属种、形态和生态上都表现出高度多样性。虽然多凿齿蜥类以拥有众多大型植食性代表而闻名，但它的主要化石地点也产出了不少小型食虫物种，中国河南上白垩统秋扒组的栾川伏牛蜥(Funiusaurus luanchuanensis)就是其中之一。伏牛蜥之前仅有一个虽近完整但较为破碎的头骨，因此提供的形态学信息有限。基于一件新发现的完整头骨的高精度CT数据和其他几件头骨和头后骨骼标本，补充了伏牛蜥的大量解剖学数据，尤其是腭区、脑颅、脊柱以及四肢部分。这些新数据将有助于建立一个更完善的多凿齿蜥类形态矩阵提供基础，从而深入讨论多凿齿蜥类的体型大小和食性转变等演化历史。
