In southern China, several Dermaptera have been observed on iNat, which we couldn't identify even on family level. Parapsalis sp., Epilandex sp., Echinosoma sp. and Spongiphoridae sp. were mentioned while trying to, but no species seemed to fit. Maybe you can chelp?
note: the pictures show several species, at least 2 or 3 morphospecies

It's actually probably a new Pseudovostox species
