Abstrakt: AbstractTwenty-eight pieces of amber from the Dominican Republic were studied. These pieces, 22–40 million years old, contain 29 cricket specimens as inclusions. Six new species in the Trigonidiidae: Trigonidiinae are described, one in the extant genus Anaxipha(A. dominica) and in three related new genera: Proanaxipha(P. latocaand P. bicolorata), Abanaxipha(A. longispinaand A. incongrua), and Grossoxipha(G. yaque). One specimen is described in the Mogoplistidae: Mogoplistinae in the extant genus Ornebius(O. ambericus). The presence of these specimens in amber proves that utilization of the boreal habitat is of long standing. Disparity in the size of the hind legs of one specimen indicates that crickets may once have had the ability to regenerate lost limbs.
