Abstract
Angle-winged katydids belong to the Microcentrini Brunner von Wattenwyl, 1878 (Phaneropterinae: Tettigoniidae). This tribe currently comprises 17 genera and 102 species with a Neotropical distribution. In this paper we described two new genera with two new species each: Capanema gen. nov. including Capanema pocanga sp. nov. (type species) and Capanema capara sp. nov.; Tukunha gen. nov., including Tukunha pinimauna sp. nov. (type species) and Tukunha minor sp. nov., comprising a total of four new species. Keys to the species of the described genera, maps and observations of natural history are provided.
