New mid-Cretaceous earwigs in amber from Myanmar (Dermaptera)

Two new genera and species of mid-Cretaceous earwigs are described and figured from Burmese (Myanmar) amber. Zigrasolabis speciosa Engel & Grimaldi, new genus and species, is represented by a series of females in a single, large piece of amber. Toxolabis zigrasi Engel & Grimaldi, new genus and species, is based on a single male. Two first-instar nymphs in the same piece as T. zigrasi may represent early stadia for this species. In addition, two further morphospecies of isolated nymphs are recorded. Both of the described genera belong to the Neodermaptera (Zigrasolabis a labidurine, Toxolabis likely an anisolabidine) but can be excluded from the Eudermaptera clade, the latter of which likely originated and diversified in the Early Tertiary or latest Cretaceous
