Two new Neotropical genera of Miracinae (Hymenoptera, Braconidae) with unusual metasomal morphology

Two morphologically unusual new neotropical genera of Miracinae, Paramomirax Whitfield and Fernandez-Triana, and Fusimirax Whitfield and Fernandez-Triana, are here proposed and described. The two new genera differ strikingly from previously known Miracinae in having completely different patterns of desclerotization of the anterior metasomal tergites. Paramomirax , so far known only from paramo vegetation at high elevation in Colombia, is represented by P. peckorum Whitfield, new species. Fusimirax , so far known only from lower elevation forests in the Dominican Republic, is described from three species, F. masneri Whitfield & Fernandez-Triana, new species, F. robusta Whitfield, new species, and F. gracilis , Whitfield, new species. None of the four species has any recorded hosts yet, although all previous Miracinae with known hosts attack leaf-mining and bark-mining moth larvae.
