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.
