 We identified three new genera and four new species of clown beetles from midcretaceous amber found in Myanmar. The new species are platycretus muscularis, olexum complenatum, credinopolis sidelii, and yethihapubescens. These species represent the first fossil record of the histurini subfamily from the Cretaceous period. They also exhibit traits associated with the subcortical lifestyle, such as flattened bodies and enlarged prostranites. Additionally, we reviewed all previously described hysterity fossil species and tested their phylogenetic positions.
