Land snails in mid-Cretaceous Burmese amber have aroused interest from palaeontologists in recent years. Here we describe three newly discovered species and a new genus belonging to families Pupinidae and Diplommatinidae: Cretatortulosa cretakachinensis sp. nov., Rhaphaulus zhuoi sp. nov. and Pulchraspira teneristoma gen. et sp. nov., using classic light microscopy and modern micro-CT scans with computer 3D reconstructions. Rhaphaulus zhuoi sp. nov represents the earliest fossil record of the genus Rhaphaulus. Our discoveries increase known species diversity of families Pupinidae and Diplommatinidae (Cyclophoroidea) during the Cretaceous of Asia. We compare these new taxa with fossil and extant representatives, discuss their significance in the context of the Pupinidae and Diplommatinidae fossil record, and consider habitats and feeding habits with reference to extant cyclophoroideans.

近年来，白垩纪中期的缅甸琥珀蜗牛引起了古生物学家的关注。在这里，我们描述了三个新发现的物种和一个属于Pu科和双翅科的新属：Cretatortulosa cretakachinensis sp。十一月，Rhaphaulus zhuoi sp.。十一月 和Pulchraspira teneristoma gen。等 十一月，使用经典的光学显微镜和具有计算机3D重建功能的现代micro-CT扫描。鼠李zhuoi sp。nov代表了Rhaphaulus属的最早化石记录。。我们的发现增加了亚洲白垩纪的Pu科和双翅科（Cyclophoroidea）的已知物种多样性。我们将这些新的分类单元与化石和现存的代表进行比较，讨论它们在Pupinidae和Diplommatinidae化石记录的背景下的重要性，并考虑到现存的环斑笔目动物的栖息地和摄食习惯。
