Key to Species of the Genus Phaneroptera

1. Male cercus apically obtuse............................................................................. 2

1’. Male cercus with acute apex............................................................................. 4

2. Cerci of male long, strongly obtuse ( Fig. 1e ), not undulate, subgenital plate narrow, posterior margin with acute lateral lobe..................................................................... Phaneroptera spinosa Bey-Bienko, 1954

2’. Cerci long, narrow apically; slightly upcurved; apex sub-obtuse ( Fig. 1d ), slightly incurved with black apical spine........ 3

3. Posterior margin of the fore wings reddish brown, cercus with sub-obtuse apex, with long undulating black apical spine.......................................................................... Phaneroptera myllocerca Ragge, 1956

3’. Fore wings uniformly green. Cercus with sub-obtuse apex with short straight black apical spine................................................................................................ Phaneroptera falcata (Poda, 1761)

4. Lateral lobe of pronotum longer then deep, shaped as in Fig. 1p . Male cerci bent inward as in Fig. 2 , 10; Stridulatory organ forming ¾ area of the fore wing, pronotum not pigmented..................... Phaneroptera gracilis Burmeister, 1838

4’. Lateral lobe of pronotum deeper than long as in Fig. 2D . Male cercus strongly bent inward crossing the subgenital plate as in Fig.1a ( Fig. 2K ), strongly acute at apex, incurved black spine at apex, subgenital plate bifurcate with acute anterior margin ( Fig. 1j ); stridulatory organ forming total area of forewing (as wider as left fore wing). Pronotum pigmented........................................................................... Phaneroptera rentzi Divya and Senthilkumar sp. nov.
