The genus Poecilimon has been object of several studies dealing with its systematics, sound communication and evolution. Yet, published data contradict in the classification, while many taxa are still insufficiently known. In the present study we supplement the knowledge of 13 poorly known species and one additional subspecies with data on their sound communication and/or morphology. Most species concerned here are classified within two acoustic groups. First group includes P. celebi, P. obtusicercus and P. toros, showing typical characteristics of the P. syriacus group. Second group is more heterogeneous. Among that, P. pechevi, P. armeniacus, P. harveyi, P. guichardi, P. haydari, P. doga, P. davisi and P. excisus present a song pattern similar to that of P. ampliatus. In addition, P. ataturki is also quite similar in basic song structure to the latter but differs in its fine song structure. Poecilimon stschelkanovzevi, with unclear relationships, is described morphologically in detail. The present study provides hints for solving some disagreement between recent revisions, proposing unification of the Poecilimon celebi with P. syriacus group and opening discussion based on close relationships of the groups ampliatus, armeniacus, davisi, luschani and the species P. guichardi on one hand, while the complex P. ataturki/glandifer shows significant differences on the other. The acoustic peculiarities of the ampliatus group allies are discussed in an evolutionary light.

During pair formation, cicadas produce acoustic signals that allow sexual partners to meet. The male is generally the emitter, producing calling songs at long range and courtship songs at short range, and the female generally the receiver. The male\–female courtship behaviour of seven taxa belonging to the Palaearctic genus Tibicina is described here for the first time. Male courtship songs consisted of a succession of groups of pulses arranged in two sub-groups. They were short in duration with strong amplitude variations. In all taxa, courtship songs were preceded by a series of 1\–5 audible wing-flicks. Differences in courtship song structure between two pairs of sympatric species, respectively T. corsica corsica/T. nigronervosa and T. corsica fairmairei/T. tomentosa, suggest that courtship signals could act as distinctive species mating recognition systems. In response to male acoustic signalling, females of T. c. corsica, T. c. fairmairei and T. nigronervosa produced audible wing-flicks such that both sexes established an acoustic duet ending in physical contact. In addition, males and females of T. tomentosa produced silent wing-flicks, a previously unknown behaviour, which could facilitate pheromone diffusion. Females did not exhibit a species-specific temporal pattern in acoustic reply to male courtship song and female wing-flick behaviour does not seem necessary for pair formation. Nevertheless, this strategy through male and female signalling ensured a reciprocal phonotactic approach that probably enhanced the likelihood for the two sexes to meet in complex habitats.

Animals adopt different strategies to communicate by means of sound in noisy envi - ronments such that some species increase, while others decrease their vocal activity in the presence of interference. Anuran amphibians from diverse latitudes exhibit both kinds of responses. Recent studies have shown that males of Batrachyla taeniata and Batrachyla antartandica from the temperate austral forest do not call in response to the presentation of advertisement calls of sympatric congeneric species. In contrast, Batrachyla leptopus responds to these signals in a similar way as to conspecific calls. The responsiveness of B. taeniata to natural abiotic interference has also been tested and found that noises of such sources produce strong increases in vocal activity. To assess the diversity in responsiveness to acoustic intrusion in this group, we exposed males of B. leptopus and B. antartandica to prolonged pre- recorded natural abiotic noises of wind, creek, rain, and to a band- pass noise centered at 2,000 Hz, at 67 dB Sound Pressure Level (SPL). The subjects did not increase their vocal activity signifi - cantly when exposed to these sounds and to band- pass noise at increasing intensities (55\–79 dB SPL). These results contrast with the increase in vocal activity observed previously in B. taeniata to continuous abiotic noise and point to the existence of di - verse strategies to confront acoustic intrusion among related species. The lack of vocal activation observed also contrasts with the responsiveness of B. leptopus to het- erospecific signals, but parallels the lack of response to such sounds in B. antartandica . Furthermore, the results obtained contrast with the responsiveness of these species to synthetic prolonged sounds observed in previous studies, suggesting that the modes of responses to acoustic intrusion may depend on previous experience, rather than having a species- specific nature.
