Abstract:
Two new arboreal katydid species (Pseudophyllinae) were recently discovered from northern Peruvian rainforest canopies using pesticide-fogging methods. Although these two species are in different tribes, they share the distinction of being the smallest of the pseudophylline katydids. One species, belonging to the platyphylliine genus Brachyauchenus Brunner von Wattenwyl, 1895, is known only from the male sex and differs from both described species of that genus by its more elongate pronotum, the mother-of-pearl markings on the pronotal disc, and differences in the shape of the male cercus and subgenital plate. The other new species belongs to the pleminiine genus Bufotettix Caudell 1918, but is easily distinguished from B. alpha Caudell by its unusually expanded pronotum and by genitalic characters. Both sexes of this species are described. The occurrence of these species in rainforest canopies suggests that many species of katydids may yet be discovered as this poorly known habitat is studied in more detail.
