“…The mid-Cretaceous Burmese amber has offered invaluable well-preserved fossils for our understanding of character evolution, phylogeny, biogeography, and palaeoecology of beetles (e.g., Cai et al, 2017aCai et al, , b, 2018Cai et al, , 2019aGimmel et al, 2019;Tihelka et al, 2021a). Burmese amber fossils also provide critical evidence of palaeodiversity of beetle families that are either currently extinct (e.g., Li et al, 2021a, b), relictual (e.g., Li et al, 2019Li et al, , 2021cTihelka et al, 2019Tihelka et al, , 2021b, or confined to the Southern Hemisphere (e.g., Li et al, 2020Li et al, , 2021d. Tomaszewska et al (2018) reported the oldest definitive fossil members of the Endomychidae entombed in the Burmese amber.…”
