Earwig nymphs (Dermaptera) from the mid-Cretaceous amber of Myanmar

Four new fossil earwig nymphs, Hirtidiplatys cardiophyllus gen. et sp. nov., Acanthodiplatys leptocercus gen. et sp. nov., and Tytthodiplatys ortholabis sp. nov. in Diplatyidae, Robustipygia calvata gen. et sp. nov. in Pygidicranidae, and one specimen unassigned to a genus which might belong to Anisolabididae, are described and figured from the mid-Cretaceous amber of Myanmar. Hirtidiplatys cardiophyllus gen. et sp. nov. and A. leptocercus gen. et sp. nov. represent the second and third earliest records of Diplatyidae, and are distinguished from other recorded nymphs in Cretaceous amber and modern lineages by the structure of their antennae and legs.
