Key to the cluster of genera of Pteronemobiini from southeastern and south Brazil comprising Amanayara,

Kevanemobius, gen. n. and Pepoyara, gen. n.

(for illustrations of characters present in Amanayara see Pereira et. al., 2010)

1A. Fore wings vestigial, reduced to small scales hidden under distal margin of pronotum; middle tibia with 2 apical spurs; pseudepiphallic rami very narrow, the apex pointing dorsally.................................... Amanayara de Mello, 1990

1B. Fore wings developed, reaching at least the second abdominal tergite; middle tibia with 3 apical spurs; pseudepiphallic rami broad, the apex horizontal or pointing ventrally (Figs. 03C, 08C)............................................... 2

2A. Fore wings similar in both sexes, dorsal field reticulated, stridulatory file and specialized areas for sound communication absent (Figs. 01F,G; 04A); fore tibiae without tympana; lowermost dorsal spur on internal side of hind tibia slightly concave ventrally near base—a vestige of a no longer present gland (Fig. 02D, F); distal projections of main lobe of pseudepihallus incurved (Fig. 03C)................................................................... Kevanemobius, gen. n.

2B. Male fore wings with stridulatory vein and other specialized veins and areas for sound communication (Fig. 06A; 9A); fore tibiae with tympana on inner face only (Fig. 07B); lowermost dorsal spur on internal side of hind tibia bearing a large, ventral gland (as in Amanayara) (Figs. 07E,F; 09E); distal projections of main lobe of pseudepiphallus straight (Fig. 08C)............................................................................................... Pepoyara, gen. n.
