Abstract Three new species of Helotidae, Palaeohelota parva gen. et sp. nov. from the Lower Cretaceous of Yixian Formation, Burmahelota pengweii gen. et sp. nov. and Metahelotella monochromata sp. nov. from the Upper Cretaceous of Northern Myanmar are described, with the first taxon representing the oldest fossil record of the family Helotidae. The diversity of Helotidae during the Cretaceous suggests the family originated and diversified at least in the Early Cretaceous. Laodiscis Lin, 1971 described in Helotidae from the Paleocene of China is here removed from Helotidae and transferred to Coleoptera, family incertae sedis.
