Madagascar is a well-known hotspot of biodiversity. However, many Orthoptera,and especially the Tettigonioidea, belong to little-studied groups.Here we describe a new genus and species of bush-cricket reared from fieldcollectedeggs. Paraplangia sinespeculo gen. nov., sp. nov. belongs to Phaneropterinaeand shares diagnostic characteristics with members of the tribe Amblycoryphiniand its African subtribe Plangiina stat. nov. Paraplangia, whichhas a chromosome number of 31 X0, differs from other African members ofthe tribe and subtribe such as Eurycorypha and Plangia, which both have 29X0. In addition to morphology, we describe the male calling song, femaleacoustic response, and mating behavior. As calling song, the male producestwo series of short syllables. At the end of the second series the femaleresponds with signals of similar duration and spectral composition as themale sounds (peak about 8-9 kHz). To make future identification easier,a key to all genera of Phaneropterinae found in Madagascar is presented.
