We describe a new species of the genus Endecous Saussure (1878), recorded at the Lapa do Cip\ó and Olhos d\’\Água caves, which are located in the Itacarambi municipality, Minas Gerais state, Eastern Brazil. Another species, E. aguassay Mews, 2008 was recordedin the surroundings of the caves. The genus Endecous corresponds to the most common cricket in Bra- zilian hypogean environments. In general, these crickets inhabit the areas around cave entrances up to the aphotic zones of caves. The genus Endecous is the only cave cricket to present troglobiomorphosis, i.e., an apterous condition. The dis- tribution of the new species is limited to these two caves, which suggests an endemism in this karst system similar to the distribution of other endemic animals, such as harvestmen and amblypygid arachnids. This species is the sixth troglobitic one described for Olhos d\’\Água cave, which sets this cave as a spot of subterranean fauna in Brazil.

When disturbed, adults of the Death\’s-head hawkmoth (Lepidoptera, Sphingidae: Acherontia atropos) produce short squeaks by drawing in and deflating air into and out of the pharynx as a defence mechanism. We took a new look at Prell\’s hypothesis of a two-phase mechanism by providing new insights into the functional morphology behind the pharyngeal sound production of this species. First, we compared the head anatomy of A. atropos with another sphingid species, Manduca sexta, by using micro-computed tomography (CT) and 3D reconstruction methods. Despite differences in feeding behaviour and capability of sound production in the two species, the musculature in the head is surprisingly similar. However, A. atropos has a much shorter proboscis and a modified epipharynx with a distinct sclerotised lobe projecting into the opening of the pharynx. Second, we observed the sound production in vivo with X-ray videography, mammography CT and high-speed videography. Third, we analysed acoustic pressure over time and spectral frequency composition of six A. atropos specimens, both intact and with a removed proboscis. Single squeaks of A. atropos last for ca. 200 ms and consist of an inflation phase, a short pause and a deflation phase. The inflation phase is characterised by a burst of ca. 50 pulses with decreasing pulse frequency and a major frequency peak at ca. 8 kHz, followed by harmonics ranging up to more than 60 kHz. The deflation phase is characterised by a less clear acoustic pattern, a lower amplitude and more pronounced peaks in the same frequency range. The removal of the proboscis resulted in a significantly shortened squeak, a lower acoustic pressure level and a slightly more limited frequency spectrum. We hypothesise that the uptake of viscous honey facilitated the evolution of an efficient valve at the opening of the pharynx (i.e. a modified epipharynx), and that sound production could relatively easily have evolved based on this morphological pre-adaptation.

Some insects produce and use sound during multiple behaviors including many aspects of reproduction. Variation in call structure depends on the evolved mor- phological structures used to produce the sound and encode function. Beetles in the genus Nicrophorus produce strid- ulation by rubbing plectra, located on the ventral side of the elytra, against a pars stridens, located on the caudal end on the fourth and fifth abdominal segment in females and males, respectively. During field surveys for the endan- gered N. americanus, survey crews have historically used a small V-shaped notch cut in the caudal end of the right elytron to serves as a permanent marking method. No study, however, has examined the effect of this marking technique on the characters of stridulation or consequences
for reproductive behavior and fitness. Here we show that one temporal and one spectral character of sound change significantly following elytron clipping, and that repro- ductive success is significantly decreased in all breedings in which a parent beetle is elytron-clipped. We recommend replacement of this marking technique with non-invasive methods to ensure conservation of this endangered species.

Loss of sexual signals should be strongly selected against when these signals are necessary for mate attraction or acquisition. Male Teleogryllus oceanicus field crickets produce a long-distance calling song to attract females. Separate genetic mutations recently evolved on the Hawaiian Islands of Kauai and Oahu, rendering approximately 90\% and 50\% of males, respectively, incapable of calling. We examined whether males from three populations, each with a distinct prevalence of this silent \‘flatwing\’ phenotype, show behavioural plasticity in response to being reared in a call-less environment. Crickets from Kauai, Oahu and Mangaia, a Cook Islands population without the flatwing phenotype, either were or were not exposed to calling song during late juvenile and early adult development. Movement assays showed that when males originating from Kauai were reared in silence, they moved sooner, moved more and spent more time walking during silent behaviour trials than did their counterparts reared with calling song. Males from Oahu and Mangaia, however, showed no such effect of acoustic rearing environment on these behaviours. This suggests that there has been directional selection on Kauai for males to respond to a silent environment by increasing their mobility, thus compensating for their lack of song and increasing their chance of encountering receptive females.

The past decade has produced an increased ecological interest in sonic environments, or soundscapes. However, despite this rise in interest and technological improvements that allow for long-term acoustic surveys in various environments, some habitats\&$\#$39; soundscapes remain to be explored. Ponds, and more generally freshwater habitats, are one of these acoustically unexplored environments. Here we undertook the first long term acoustic monitoring of three temperate ponds in France. By aural and visual inspection of a selection of recordings, we identified 48 different sound types, and according to the rarefaction curves we calculated, more sound types are likely present in one of the three ponds. The richness of sound types varied significantly across ponds. Surprisingly, there was no pond-to-pond daily consistency of sound type richness variation; each pond had its own daily patterns of activity. We also explored the possibility of using six acoustic diversity indices to conduct rapid biodiversity assessments in temperate ponds. We found that all indices were sensitive to the background noise as estimated through correlations with the signal-to-noise ratio (SNR). However, we determined that the AR index could be a good candidate to measure acoustic diversities using partial correlations with the SNR as a control variable. Yet, research is still required to automatically compute the SNR in order to apply this index on a large data set of recordings. The results showed that these three temperate ponds host a high level of acoustic diversity in which the soundscapes were variable not only between but also within the ponds. The sources producing this diversity of sounds and the drivers of difference in daily song type richness variation both require further investigation. Such research would yield insights into the biodiversity and ecology of temperate ponds.

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.

Here we aimed to assess the vocal repertoire of the solitary Sahamalaza sportive lemur, Lepilemur sahamalazensis, and to investigate potential communication functions. We recorded every sportive lemur vocalization we heard during 1000 h of nocturnal observations of eight collared individuals, as well as opportunistic searches in the Ankarafa Forest, Sahamalaza Peninsula in northwest Madagascar. In addition, we used playback experiments with four call types to clarify call function. We measured both temporal and spectral properties to describe calls quantitatively and used cross-validated discriminant function analysis to validate call types that we identified from a preliminary qualitative inspection of the spectrograms of 107 calls. We identified six distinct loud call types with the possibility of a seventh call type, with six loud call types similar to those of Lepilemur edwardsi and two loud call types similar to those of four other sportive lemur species. The described call types most likely function in mate advertisement, offspring care, and territorial defense.

Background
Sound collections for singing insects provide important repositories that underpin existing research (e.g. Price et al. 2007 at http://bio.acousti.ca/node/11801; Price et al. 2010) and make bioacoustic collections available for future work, including insect communication (Ordish 1992), systematics (e.g. David et al. 2003), and automated identification (Bennett et al. 2015). The BioAcoustica platform (Baker et al. 2015) is both a repository and analysis platform for bioacoustic collections: allowing collections to be available in perpetuity, and also facilitating complex analyses using the BioVeL cloud infrastructure (Vicario et al. 2011). The Global Cicada Sound Collection is a project to make recordings of the world\&$\#$39;s cicadas (Hemiptera: Cicadidae) available using open licences to maximise their potential for study and reuse. This first component of the Global Cicada Sound Collection comprises recordings made between 2006 and 2008 of Cicadidae in South Africa and Malawi.

New Information
This collection of sounds includes 219 recordings of 133 voucher specimens, comprising 42 taxa (25 identified to species, all identified to genus) from South Africa and Malawi. The recordings have been used to underpin work on the species limits of cicadas in southern Africa, including Price et al. 2007 and Price et al. 2010. The specimens are deposited in the Albany Museum, Grahamstown, South Africa (AMGS).

The harvesting of acoustic data as occurrence records by GBIF has been implemented by the Scratchpads Team at the Natural History Museum, London. This link increases the value of individual recordings and the BioAcoustica platform within the global infrastructure of biodiversity informatics by making specimen/occurence records from BioAcoustica available to a wider audience, and allowing their integration with other occurence datasets that also contribute to GBIF.

"Yelping" is also associated with contacts between males.
