A new mole cricket (Orthoptera: Gryllotalpidae) from mid-Cretaceous Burmese amber

A new mole cricket, Tresdigitus rectanguli gen. et sp. nov., is described based on a well-preserved specimen from mid-Cretaceous Burmese amber. It can be definitely attributed to the family Gryllotalpidae (mole cricket), but cannot be incorporated into any existing subfamily of Gryllotalpidae because of the unusual combination of its characteristics. This new find is not only the second record of Gryllotalpidae from mid-Cretaceous Burmese amber, but also provides novel morphological diversity in Gryllotalpidae, showing original characteristics of body structures especially protibial dactyls.
