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 field-collected eggs. Paraplangia sinespeculo gen. nov., sp. nov. belongs to Phaneropterinae and shares diagnostic characteristics with members of the tribe Amblycoryphini and its African subtribe Plangiina stat. nov. Paraplangia, which has a chromosome number of 31 X0, differs from other African members of the tribe and subtribe such as Eurycorypha and Plangia, which both have 29 X0. In addition to morphology, we describe the male calling song, female acoustic response, and mating behavior. As calling song, the male produces two series of short syllables. At the end of the second series the female responds with signals of similar duration and spectral composition as the male sounds (peak about 8-9 kHz). To make future identification easier, a key to all genera of Phaneropterinae found in Madagascar is presented.

Stridulating Uhler\&$\#$39;s katydids produce the most complex song known for insects. Series of four types of sounds are made in stereotyped sequence. Sound-synchronized high-speed photography reveals that each type of sound is produced by a distinctively different wing-movement cycle. The most complex of these cycles includes a two-step closure and a nearly silent close-open movement.

Acoustic signalling during pair formation is more complex in Phaneropterinae than in any other Ensifera. Lone males of most species produce more than one kind of sound, and females of all species studied produce sound during pair formation, a phenomenon with no known parallel in other Ensifera.

This report includes (1) an analysis of the singing behaviours and the descriptions of sounds of nine species of Phaneropterinae and (2) the results of numerous experiments with these species to determine the behavioural significance of their sounds. Three kinds of male-female acoustic systems occur in the species studied: (1) the male makes a particular sound, the female answers with a tick and the male goes all the way to the female, (2) the male makes one kind of sound which attracts females from a distance (but not at close-range), the male makes a second sound which the female answers with a tick and the male goes to the female from close-range, and (3) the male makes one kind of sound, the female answers with a tick, the male moves towards the female from a distance (but not all the way), and the male produces a second kind of sound which attracts the female the remaining distance. Some species produce stereotyped sequences of different kinds of sounds; different responses occur to different sounds in the sequences.
