Ensifera present an appropriate and interesting model for the study of acoustic communication, because of their diverse signal and communication modalities, and due to their accessibility for field and laboratory studies. Several hypotheses have been proposed to explain the acoustic evolution of Ensifera, but they were elaborated without any reference to a falsifiable phylogeny, and were consequently highly speculative. Similarly, phylogenetic relationships between ensiferan clades have not hitherto been studied using modern standard methodology, and the sole cladistic analysis by Gwynne in 1995 was methodologically flawed. No sound hypothesis therefore currently exists for ensiferan phylogeny, which precludes historical analysis of their communication modalities. In the present paper, the phylogeny is established on the basis of morpho-anatomical characters and used to analyse the evolution of acoustic communication in this clade by mapping the characters related to auditory and stridulatory structures onto the resultant trees. Cladistic analyses resulted in two equi-parsimonious cladograms (length 154, C 64, CI 58, RI 61) with the following topologies: (1) [(Grylloidea\–Gryllotalpidae) (Rhaphidophoridae (Schizodactylidae (Gryllacrididae ((Stenopelmatidae\–Cooloola) (Anostostomatidae (Prophalangopsis (Cyphoderris (Tettigoniidae\–Lezina))))))))] (2) [(Grylloidea\–Gryllotalpidae)(Rhaphidophoridae (Schizodactylidae (Gryllacrididae\–Cooloola\–(Stenopelmatidae (Anostostomatidae (Prophalangopsis (Cyphoderris (Tettigoniidae\–Lezina))))))))]. According to these topologies, Ensifera were ancestrally devoid of acoustic and hearing systems. An acoustic (tegminal or femoro-abdominal) apparatus appeared a number of times independently with convergent structures. Similarly, tibial tympana developed several times independently. Moreover, four hypotheses (each according to a definite pattern of character transformation) can be proposed to explain the evolution of acoustic communication in the different ensiferan clades and relate it to a definite communicatory context. These hypotheses do not apply equally to ensiferan subclades. Grylloidea and Gryllotalpoidea could have experienced convergently a direct development of an intraspecific acoustic communication. Acoustic communication in Tettigoniidea has evolved more ambiguously, and may either have resulted from a direct evolution analogous to that having occurred in Gryllidea, or have developed in a completely different behavioural context. Future studies of acoustic communication in the different ensiferan clades will have to take into account the fact that the involved structures most often are not homologous and that their evolution may not have taken place in similar conditions. Different hypotheses of acoustic communication evolution may apply to different clades, and there may be no single explanation for acoustic communication in Ensifera.

New communication signals can evolve by sensory exploitation if signaling taps into preexisting sensory biases in receivers [1 ;\  2]. For mate attraction, signals are typically similar to attractive environmental cues like food [3; 4; 5 ;\  6], which amplifies their attractiveness to mates, as opposed to aversive stimuli like predator cues. Female field crickets approach the low-frequency calling song of males, whereas they avoid high-frequency sounds like predatory bat calls [7]. In one group of crickets (Eneopterinae: Lebinthini), however, males produce exceptionally high-frequency calling songs in the range of bat calls [8], a surprising signal in the context of mate attraction. We found that female lebinthines, instead of approaching singing males, produce vibrational responses after male calls, and males track the source of vibrations to find females. We also demonstrate that field cricket species closely related to the Lebinthini show an acoustic startle response to high-frequency sounds that generates substrate vibrations similar to those produced by female lebinthine crickets. Therefore, the startle response is the most likely evolutionary origin of the female lebinthine vibrational signal. In field crickets, the brain receives activity from two auditory interneurons; AN1 tuned to male calling song controls positive phonotaxis, and AN2 tuned to high-frequency bat calls triggers negative phonotaxis [9 ;\  10]. In lebinthine crickets, however, we found that auditory ascending neurons are only tuned to high-frequency sounds, and their tuning matches the thresholds for female vibrational signals. Our results demonstrate how sensory exploitation of anti-predator behavior can evolve into a communication system that benefits both senders and receivers.

The insect Uvarovites inflatus Uvarov is highly appreciated in China. It is known for its distinctive songs and horn-like forewings and is raised commercially for insect lovers. U. inflatus was previously categorized as part of the mono- typic genus Uvarovites; however, there was little molecular evidence to support this taxonomic classification. This study obtained and investigated the mitogenome of U. inflatus, and its songs were characterized and compared with other Ensifera species whose mitogenomes are available. By performing the mitochondrial analysis, we were able to assess the phylogenetic relationships between these species and discuss the evolution of Ensifera calling songs. The mitogenome of U. inflatus is 15,956bp in length and contains 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and 1 control region. The organization and orientation of the U. inflatus mitogenome are similar to those of other Tettigonioidea species. Phylogenetic analysis based on 13 protein-coding genes showed that the superfamily Tettigonioidea is monophyletic, as are the other six tested subfamilies from Tettigonioidea. Our results also indicated that Grylloidea is monophyletic. A Bayesian relaxed clock analysis showed that the differentiation of U. inflatus and Gampsocleis gratiosa Brunner occurred in the middle Miocene, suggesting that their speciation occurred over a long evolutionary period. The results provide significant support for the establishment of the monotypic genus Uvarovites. Calling song analysis showed that at least two discrete steps of independent evolution occurred during the change from pure tone to broadband noise, and that the ancestor of existing Ensifera was more likely to have emitted pure-tone songs than broadband signals. Together, the mitogenome, molecular clock, and acoustic data allowed us to clarify the taxonomic state of U. inflatus and propose a timeline for the evolution of Ensifera songs.

Male tree cricket (Orthoptera : Oecanthidae) calling songs are used by females to locate conspecific mates. Changes in these songs are crucial to speciation. Since certain features of cricket sounds are correlated with the structures of the stridulatory organs, changes in stridulatory organs must be correlated with changes in songs. Surprisingly, there is no established hypothesis to explain the mechanism of morphological change associated with changes in songs. Some alternative possibilities are explored, with reference to incidental effects. Available evidence suggests that stridulatory organs are genetically stable and that changes in these organs occur in steps rather than gradually.
