A third genus and species of fossil pygidicranid earwigs from Burmese amber is described and figured as Stonychopygia leptocerca Engel, Huang, Thomas, and Cai, gen. et sp. nov. (type species of Stonychopygia Engel and Huang, gen. nov.; Stonychopygiinae Engel and Huang, subfam. nov.). Stonychopygia have features similar to the subfamily Echinosomatinae such as the combination of shorter, subequal second and third flagellomeres and femora that are neither compressed or keeled. However, the new fossil species differs from echinosomatines in many details, particularly the slender form, head longer than wide, slender scape, slender and elongate forceps, and absence of stout, short bristles over the integument. The new fossil is compared with its contemporaneous and modern relatives, and comments are provided regarding the classification of Pygidicranoidea, with the genus Haplodiplatys Hincks removed from Diplatyidae to Haplodiplatyidae Engel, fam. nov.
