Inclusions of terrestrial mollusks in Kachin amber are of increasing interest to palaeontologists in recent years. Here we describe a new genus (Cretadiostoma gen. nov.) including two new species (C. caperatum sp. nov., C. umbilicarinatum sp. nov.) of the gastropod family Pupinidae based on 12 specimens from mid-Cretaceous Kachin amber of northern Myanmar. Furthermore, we describe the second species of genus Coptocheilus Gould, 1862 from Kachin amber, namely Coptocheilus kachinensis sp. nov. An overview of the Pupinidae species found in Kachin amber is provided. The radiation and morphological comparison of Pupinidae (Caenogastropoda: Cyclophoroidea) is discussed on the basis of 12 species belonging to seven genera from Kachin amber. |
