A new genus and species, Magnidactylus robustus gen. et sp. nov., is described on the basis of a wellpreserved orthopteran insect from mid-Cretaceous Burmese amber and attributed to the subfamily Dentridactylinae of the family Tridactylidae (Orthoptera: Tridactyloidea). This new taxon not only provides novel morphological diversity in Tridactylidae (pygmy mole crickets), but also represents the largest one of all the tridactylids reported from mid-Cretaceous Burmese amber. The pygmy mole crickets of mid-Cretaceous Burmese amber had no swimming plates, suggesting that their habitat was less related to freshwater than the extant ones. (C) 2020 Elsevier Ltd.
