Summary: | Cretaceous Myanmar amber is abundant in inclusions belonging to the genus <i>Palaeoglaesum</i>. In addition, a significant morphological diversity among representatives of <i>Palaeoglaesum</i> can be observed. However, none of its representatives have been found in other fossil materials. Herein three new species: <i>P. stebneri</i> sp. nov., Skibińska and Krzemiński <i>P. teres</i> sp. nov. Skibińska and Albrycht, and <i>P. pilosus</i> sp. nov. Skibińska, Krzemiński and Zhang from Cretaceous Myanmar amber are described and illustrated. The very small size and characters of male hypopygium with aedeagus strongly bent and apically forked are pertinent to diagnosing the genus and species. New materials show that this genus and the whole subfamily Bruchomyiinae were probably more abundant and more diverse than the presently known extant fauna.
