Vibrational communication is known in some subterranean insects. Except for their use in sexual signaling, vibration behavior has rarely been reported. We report here four distinct types of substrate-based vibration behaviors in the mole cricket, Gryllotalpa orientalis, which are not associated with sexual signaling because of the occurrence of these behaviors in nymphs: (1) scraping with the forelegs; (2) foreleg taps (tapping with the forelegs); (3) palpal taps (tapping with the maxillary palpi); and (4) tremulation (back-and-forth movement of the whole body). Scraping is hypothesized to be used for the inspection of borrows. Foreleg taps are possibly informing nearby individuals of their presence, because it is never observed in solitary conditions. Palpal taps are rarely observed and its function is unknown. Tremulation is possibly related to avoidance of conspecific individual approaching and touching. The combination of the four vibration behaviors in the mole cricket may be unique among insects.

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 phylogenetic relationships of 39 species of Eneopterinae crickets are reconstructed using four molecular markers (16S rRNA, 12S rRNA, cytochrome b , 18S rRNA) and a large morphological data set. Phylogenetic analysis via direct optimisation of DNA sequence data using parsimony as optimality criterion is done for six combinations of weighting parameter sets in a sensitivity analysis . The results are discussed in a twofold purpose: W rst, in term of signi W cance of the molecular markers for phylogeny reconstruction in Ensifera, as our study represents the W rst molecular phylogeny performed for this insect suborder at this level of diversity; second, in term of corrobora- tion of a previous phylogeny of Eneopterinae, built on morphological data alone. The four molecular markers all convey phylogen etic signal, although variously distributed on the tree. The monophyly of the subfamily, that of three over W ve tribes, and of 10 over 13 genera, are recovered. Finally, previous hypotheses on the evolution of acoustic devices and signals in the Eneopterinae clade are brie X y tested, and supported, by our new data set.

A revision of Eneopterinae crickets from the Neotropical region is achieved in a cladistic perspective using for the first time characters of male and female genitalia and male forewing venation. Each genus is redefined and its monophyly assessed with reference to all known Eneopterinae genera. 6 new species are described (Eneoptera gracilis, E. nigripedis, Ligypterus belmontensis, L. linharensis, L. pernambucensis and Ponca hebardi) and an identification key is proposed for both males and females. Phylogenetic relationships are discussed and distributions characterised.

In the present study, we report the high-coverage complete mitochondrial genome (mitogenome) of the cricket Cardio- dactylus muiri Otte, 2007. The mitogenome was sequenced using a long-PCR approach on an Ion Torrent Personal Ge- nome Machine (PGM) for next generation sequencing technology. The total length of the amplified mitogenome is 16,328 bp, representing 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes and one noncoding region (D-loop region). The new sets of long-PCR primers reported here are invaluable resources for future comparative evolu- tionary genomic studies in Orthopteran insects. The new mitogenome sequence is compared with published cricket mito- genomes. In the taxonomic part, we present new records for the species and describe life-history traits, habitat and male calling song of the species; based on observation of new material, the species Cardiodactylus buru Gorochov \& Robillard, 2014 is synonymized under C. muiri.

The present study describes Gnominthus, a new genus of Eneopterinae crickets from New Guinea Island (Papua New Guinea), which belongs to the tribe Lebinthini. Descriptions focus on general morphology, male and female genitalia, and forewing venation. Bioacoustical analyses of the calling song and the description of the mating behavior are also provided. The novelties found here increase the idea hypothesized before that the Lebinthini may represent a very diverse group in terms of shapes, behaviors and acoustic signals.
