| - This paper addresses the phylogenetic relationships of the tettigoniid genera Dectinomima Caudell and Uchuca Giglio-Tos. A new species is named of Dectinomima and the genus redescribed. Males of this genus present the odd characteristic of a stridulatory file with extreme tooth density: >600 teeth. Four new species of Uchuca are described, all alate. In four the vestigial file of the right tegmen is well developed; the functional file in two species terminates suddenly, well short of the wing base, something not seen before in a katydid. This paper contains a revision of the genus Dectinomima, with description of the male of D. jenningsi and of a new species: D. sagittata. Based on the male genitalia, Dectinomima differs considerably from Uchuca. Both genera appear to be closely related monophyletic groups, as previously thought, but they are members of a larger generic complex, incorporating the genus Paranelytra and several undescribed genera from the New World. A complete analysis of their calling songs accompanies detailed descriptions of two of the new Uchuca spp. These acoustic signals are ultrasonic and present considerable interspecific variation in quality factor (Q).
