Nanoleptopoda gen. nov.

Type species: N. nigrifrons sp. nov., described below; in tribe Odonturini .

Etymology. Combination of Greek nanos (dwarf), leptos (delicate and slender), and podi (leg), meaning thinlegged gnome katydid (translation of the type species’ provisional German name).

Diagnosis. Resembling genus Parangara in overall appearance, being also tiny and long-legged. But in Nanoleptopoda the anterior and posterior pronotum margins are only very little upcurved, and the lateral lobes are narrowed caudally, especially in the male. This is related with the male having a very large vertically elongated auditory spiracle that is completely unconcealed. The female’s auditory spiracle is much smaller. The pronotal disk is practically smooth without any appreciable transverse sulcus, in contrast to the description of Angara with a single species from Brazil, state of Rio de Janeiro (Brunner von Wattenwyl 1891). Tegmina are slightly longer than the pronotum to almost three times as long, leaving most of the abdomen or at least its rear portion unconcealed in live individuals. Abdominal tergites without projections. Forecoxae unarmed. Hind femora in basal third strongly thickened, fore and middle femora very slender, all femora unarmed but all genicular lobes ending in delicate spines (and mostly having also a minute basal spine). Fore and middle tibia with a few very delicate and inconspicuous ventral spines, hind tibia distally with a few delicate ventral spines and well developed dorsal spines. The ovipositor is very broad, rather abruptly upcurved at the base, its dorsal margin and end finely serrate, and the latter broadly rounded. The coloration is rich in contrast, including lucid green, various shades of brown, and reddish, white, and black markings—probably serving as camouflage in a mossy mountain rainforest environment. As almost all neotropical rainforest katydids the two known species are nocturnal.
