Platycleis galvagnii n. sp. from Sardinia (Italy) is described. In general habitus the new taxon is close to Platycleis sensu strictu, albeit very small in size. When looking at other characters the species does not seem to fit within one of the groups recognised within Platycleis s.l., but for the moment the species is placed in Platycleis s.s.. The species is characterised by a range of morphological and bioacoustic characters. Its real affiliations with other species within the Platycleis complex need to be established further. For the moment the species is known only from the type locality, Gennargentu mountain in the central part of Sardinia.

The new species Anterastes davrazensis sp. n. (Orthoptera, Tettigoniidae) is described from south-eastern Turkey. Description, diagnosis and relationships of the new species were studied utilizing morphology, male calling songs and 16S rDNA sequence data from all species in the genus. Morphology and song syllable structure indicate A. davrazensis sp. n. is related to A. uludaghensis. Phylogenetic analyses based on representative haplotypes of 16S rDNA, using Sureyaella bella, Parapholidoptera distincta and Bolua turkiyae as outgroups, also suggested strong support to the relationship of these two species. A. davrazensis sp. n. differs from its closest relative A. uludaghensis by the higher number of stridulatory pegs and the song, consisting of irregular syllable groups.

Mating behaviour of the katydid Metaballus sp. varies. At sites QS and DB (in 1982) females competed for access to calling males and males chose mates by mating with heavier, more fecund females. At another site (BR) there was no evidence of role-reversal in reproductive behaviour, and males were observed to compete for mates. This species has a large spermatophore, a product of male reproductive glands, that is eaten by the female after mating. Males at the DB site had small reproductive glands. This suggests that some aspect of the QS and DB environments decreases spermatophore production; spermatophores become a limiting resource for females resulting in the reversal in reproductive roles observed at these sites. A field experiment that involved moving individuals from site BR to QS in 1983 determined that mating system was influerced by site (Table 1). At BR, males produced a continuous calling song, a third of the males observed attracted mates, and called for about 30 min before the female arrived; courtship duration was short. Males that were moved from BR to QS encountered a higher density of receptive females as all males attracted females after an average of just 3 min of calling. They changed their behaviour by producing short periodic bursts of song (“zipping”), and by courting females for long periods of time. The long courtship period may function as as a mate-assessment period for males. The reproductive behaviour of BR males moved to QS differed from that of native QS males only in the length of time spent in copula.

Body color dimorphism is a common phenomenon in a wide range of insect taxa. In Gampsocleis sedakovii obscura (Walker), the two morphs are green and brown. In order to explore the variation within the same species with different body color phenotypes, morphology, genetics, and male calling songs were compared within Gampsocleis from Inner Mongolia, China. Recordings of the male calling songs were compared based on the acoustic variables including pulse duration, pulse interval, dominant frequency, highest frequency, and lowest frequency. This analysis was combined with sequencing of mitochondrial DNA cytochrome c oxidase subunit I and cytochrome c oxidase subunit II and examination of morphological traits to perform cluster analyses. The morphological and the mitochondrial genetic analyses revealed no differences between green and brown morphs, but the acoustic analysis showed completely different male calling between the morphs, thus suggesting that there is a connection between acoustic signals and body color dimorphism in G. s. obscura. These findings also revealed that the acoustic variation with body color dimorphism could provide evidence for insect acoustic signal divergence and the process of subspeciation, even speciation.

Conspicuous signals, such as the calling songs of tettigoniids, are intended to attract mates but may also unintentionally attract predators. Among them bats that listen to prey-generated sounds constitute a predation pressure for many acoustically communicating insects as well as frogs. As an adaptation to protect against bat predation many insect species evolved auditory sensitivity to bat-emitted echolocation signals. Recently, the European mouse-eared bat species Myotis myotis and M. blythii oxygnathus were found to eavesdrop on calling songs of the tettigoniid Tettigonia cantans. These gleaning bats emit rather faint echolocation signals when approaching prey and singing insects may have difficulty detecting acoustic predator-related signals. The aim of this study was to determine (1) if loud self-generated sound produced by European tettigoniids impairs the detection of pulsed ultrasound and (2) if wind-sensors on the cercal organ function as a sensory backup system for bat detection in tettigoniids. We addressed these questions by combining a behavioral approach to study the response of two European tettigoniid species to pulsed ultrasound, together with an electrophysiological approach to record the activity of wind-sensitive interneurons during real attacks of the European mouse-eared bat species Myotis myotis. Results showed that singing T. cantans males did not respond to sequences of ultrasound pulses, whereas singing T. viridissima did respond with predominantly brief song pauses when ultrasound pulses fell into silent intervals or were coincident with the production of soft hemi-syllables. This result, however, strongly depended on ambient temperature with a lower probability for song interruption observable at 21uC compared to 28uC. Using extracellular recordings, dorsal giant interneurons of tettigoniids were shown to fire regular bursts in response to attacking bats. Between the first response of wind-sensitive interneurons and contact, a mean time lag of 860 ms was found. This time interval corresponds to a bat-to-prey distance of ca. 72 cm. This result demonstrates the efficiency of the cercal system of tettigoniids in detecting attacking bats and suggests this sensory system to be particularly valuable for singing insects that are targeted by eavesdropping bats.

The role of the tympana0 aStimulus transmission in the auditory receptor organs of the for3 a

The auditory organs of the tettigoniid are located just below the femoral tibial joint in the forelegs. Structurally each auditory organ consists of a tonotopically organized crista acustica and intermediate organ and associated sound conducting structures; an acoustic trachea and two lateral tympanic membranes located at the level of the receptor complex. The receptor cells and associated satellite structures are located in a channel filled with hemolymph fluid. The vibratory response characteristics of the tympanic membranes generated by sound stimulation over the frequency range 2–40 kHz have been studied using laser vibrometry. The acoustic trachea was found to be the principal structure through which sound energy reached the tympana. The velocity of propagation down the trachea was observed to be independent of the frequency and appreciably lower than the velocity of sound in free space. Structurally the tympana are found to be partially in contact with the air in the trachea and with the hemolymph in the channel containing the receptor cells. The two tympana were found to oscillate in phase, with a broad band frequency response, have linear coherent response characteristics and small time constant. Higher modes of vibration were not observed. Measurements of the pattern of vibration of the tympana showed that these structures vibrate as hinged flaps rather than vibrating stretched membranes. These findings, together with the morphology of the organ and physiological data from the receptor cells, suggest the possibility of an impedance matching function for the tympana in the transmission of acoustic energy to the receptor cells in the tettigoniid ear.

In grasshoppers, the auditory and vibra- tional senses converge on the same ventral-cord neurons. All neurons in the ventral cord that discharge impulses in response to either airborne-sound or vi- bration stimuli also receive synaptic inputs from the other sensory system. The latter elicit either sub- threshold excitation or inhibition.

The coding of the conspecific song in the responses of most ventral-cord neurons of Tettigonia cantans is considerably improved when the stimulus consists not of simulated natural sounds alone, but of such
sounds together with either maintained vibration or vibration matched to the temporal structure of the song.

Stridulating tettigoniids produce both airborne and substrate-conducted sound. Thus the perception of airborne sound and vibration, and their simulta- neous processing in individual ventral-cord neurons, may be of fundamental importance - not only in localizing a nearby sound source, but also in facilitat- ing the recognition of conspecific signals.

Song of the bush cricket Tettigonia cantans were analysed, and synthetic song models constructed, to reproduce both the natural variation in the song parameters and the modified spectral balance (high-frequency attenuation) seen after songs are transmitted through the natural habitat. In the laboratory, song models were replayed to female insects in a series of two-choice trials and the phonotactic response was used as the criterion for song preference. Controlling single variables in the models showed that females orientated preferentially to lower-pitched songs, louder songs and models with a relatively louder high-frequency content. Further trials confirmed song frequency to be an important cue and demonstrated spectral balance to be a more effective stimulus than intensity per se. Song models replayed in the field to established (‘territorial’) singing males produced different behavioural responses depending on the song frequency. To low-pitched songs, males were more likely to reduce their singing activity and move away from the sound source. High-pitched song often resulted in an increase in the singing rate and an approach to the loudspeaker. A model without the high-frequency band elicited no detectable response, the subject continuing to sing normally from the same perch. These results support the hypothesis that the spectral balance of the song can be used for range determination. The poor correlation between the measured song variables and morphology suggests that song in this species advertises the status of the male rather than other single attributes such as size or weight.

Investigated the dispersion patterns of singing male bush crickets (Tettigonia cantans) and analyzed the behavioral patterns of established males elicited by the song of a conspecific. Results show that, apart from sites with sparse vegetation, stridulating males tend to show clumped distribution in areas with dense plant populations and that, within clumps, individuals are regularly spaced. Males seem to space themselves according to the song intensities they receive from each other. Between-close-neighbors rivalry behavior is expressed by males producing alternating songs, in an approach toward a constantly singing insect, or in an aggressive encounter. Of these 3 behavior patterns, aggressive encounters are most common in high-density populations. Rivalry does not influence the dispersion pattern of the males. A hypothesis is inferred from observations on female behavior: Rivalry itself constitutes an attractive stimulus for females. The problem still left for further research is if, and how, female bush crickets discriminate and choose their mate from a population of singing males.

The calling songs of decticines remain largely undescribed. Songs of Neduba macneilli and N. sierranus were recorded and analysed. These species have mirror-image tegmina and individual specimens exhibit reversed wing overlap. Wing symmetry and the elaborate pronotum characteristic of this genus are discussed as adaptations which increase the efficiency of sound radiation.

Male katydids produce mating calls by stridulation using specialized structures on the forewings. The right wing (RW) bears a scraper connected to a drum-like cell known as the mirror and a left wing (LW) that overlaps the RW and bears a serrated vein on the ventral side, the stridulatory file. Sound is generated with the scraper sweeping across the file, producing vibrations that are amplified by the mirror. Using this sound generator, katydids exploit a range of song carrier frequencies (CF) unsurpassed by any other insect group, with species singing as low as 600 Hz and others as high as 150 kHz. Sound generator size has been shown to scale negatively with CF, but such observations derive from studies based on few species, without phylogenetic control, and/or using only the RW mirror length. We carried out a phylogenetic comparative analysis involving 94 species of katydids to study the relationship between LW and RW components of the sound generator and the CF of the male's mating call, while taking into account body size and phylogenetic relationships. The results showed that CF negatively scaled with all morphological measures, but was most strongly related to components of the sound generation system (file, LW and RW mirrors). Interestingly, the LW mirror (reduced and non-functional) predicted CF more accurately than the RW mirror, and body size is not a reliable CF predictor. Mathematical models were verified on known species for predicting CF in species for which sound is unknown (e.g. fossils or museum specimens).

To examine acoustic differences between macropters and brachypters, we recorded and analyzed the calling songs of the 2 forms. Moreover, the vocal organs of E. e. engelhardti were also observed under optical and scanning electric microscopy. As a result, there were 3 “dynamic” song traits which had signi cant differences between the 2 forms, but no obvious differences were observed in vocal organs. For macropters, we assumed that differentiation of these calling songs showed compensation for a reproductive disadvantage. Finally, some molecular biology experiments were conducted to examine differences between the 2 forms at the molecular biology level; as a result, brachypterous insects were grouped in a clade, while macropterous insects were grouped into another, which indicates that these molecular differences had already occurred before these macropters migrated.10ainsect songs10akatydid10atoothed files10awing dimorphism1 aWang, Yinliang1 aZhang, Jian1 aLi, Xiao-Qiang1 aRen, Bing-Zhong uhttps://bio.acousti.ca/ja/node/4779001316nas a2200229 4500008004100000245019600041210006900237300001200306490000900318520050400327653001700831653001700848653001800865653001100883100002300894700002700917700001800944700002900962700002800991700002601019856004101045 2017 eng d00aNew data on the bush-cricket Montana medvedevi (Orthoptera: Tettigoniidae), critically endangered in Europe (EU 28), and a comparison of its song with all known song patterns within the genus0 aNew data on the bushcricket Montana medvedevi Orthoptera Tettigo a527-5420 v42633 a

The genus Tettigonia includes 26 species distributed in the Palaearctic region. Though the Green Bush-crickets are widespread in Europe and common in a variety of habitats throughout the Palaearctic ecozone, the genus is still in need of scientific attention due to the presence of a multitude of poorly explored taxa. In the present study, we sought to clarify the evolutionary relationships of Green Bush-crickets and the composition of taxa occurring in the Western Palaearctic. Based on populations from 24 disjunct localities, the phylogeny of the group was estimated using sequences of the cytochrome oxidase subunit I (COI) and the internal transcribed spacers 1 and 2 (ITS1 and ITS2). Morphological and acoustic variation documented for the examined populations and taxa was interpreted in the context of phylogenetic relationships inferred from our genetic analyses. The trees generated in the present study supported the existence of three main lineages: “A”—composed of all sampled populations of Tettigonia viridissima and the Tettigonia vaucheriana complex, “B”—comprising Tettigonia caudata, Tettigonia uvarovi, and the Tettigonia armeniaca complex, and “C”—consisting of Tettigonia cantans. The present study provides the first phylogenetic foundation for reviewing the systematics of Tettigonia (currently classified mostly according to morphological characteristics), proposing seven new synonymies.

Monitoring biodiversity over large spatial and temporal scales is crucial to assess the impact of global changes and environmental mitigation measures. However, large-scale monitoring of invertebrates remains poorly developed despite the importance of these organisms in ecosystem functioning. The development of new recording techniques and new methods of automatic species recognition based on sound detection and easily applicable within a citizen-science framework, offers interesting possibilities. However, the value of such protocols has not been tested for the study of temporal trends on a large spatial scale.

We used an acoustic region-wide citizen-monitoring program of Orthoptera, conducted along roads, to assess the relevance of automatic species recognition methods to detect temporal trends while taking into account spatial and seasonal patterns of two Orthoptera species activity (Tettigonia viridissima Linnaeus, 1758, and Ruspolia nitidula Scopoli, 1786) at a large scale. Additionally, we tested the effect of climate and land-use variables on spatio-temporal abundance patterns using generalized linear mixed models. We found negative temporal trends for the two species across the survey period (2006–2012). The spatial variations were largely explained by the geoclimatic conditions and, to a lesser extent, by land use (negative effects of urbanization). The temporal variations were highly correlated to the climatic conditions of the year, and of the previous year (nonlinear effect of temperature, precipitation).

To our knowledge, this paper describes the first successful attempt to calculate large-scale temporal trends of insect populations on the basis of an automatic identification process of acoustic data. We argue that acoustic monitoring along roads, coupled with the automatic recognition of species sounds, offers several advantages for assessing Orthoptera biodiversity response to global changes and environmental measures.

Understanding the relationship between mating trait evolution and speciation requires data from a variety of taxa. I analysed the calling songs of the shield-back katydid genus Aglaothorax, which represents a little-known lineage of acoustic insects. Field-collected males of all described species and most subspecies were recorded under controlled laboratory conditions. Discriminant analysis was 90.5% successful in separating song types, but the song types thus delineated did not correspond to currently recognized taxa as defined by morphology. The discrepancy is caused by two species, Aglaothorax morsei and Aglaothorax longipennis, the songs of which vary in a cline across the Transverse Ranges and the Los Angeles Basin of southern California. From west to east, pulse rate and duty cycle decrease and interpulse interval increases. Selection for species recognition at a contact zone, sexual selection and interactions between signals and the environment are considered as causes of the cline.

Flash photography of the wings of a decticine katydid, Metrioptera sphagnorum (F. Walker), during stridulation, indicates that major trains of sound pulses of both song modes coincide with wing closures. The song mode characterized by intense ultrasonics is generated by tooth–scraper interactions over an interval of approximately 60 teeth at the lateral end of the file. A more medial file region is employed for the audio-dominated mode. Tooth removal confirms the role of different file regions in mode generation. Each pulse of the ultrasonic mode closure is a wave train of 10–15 waves of uniform amplitude, approximating a pure tone frequency of 33 kHz.

In Atlanticus gibbosus Scudder the wing-cycle rate during stridulation is a linear function of temperature: ŷ = 1.35 T — 9.56 (T = °C; r2 = .99). In A. dorsalis (Burmeister) the tooth-strike rate during stridulation can be described approximately as either a linear or an exponential function of temperature: ŷ = 33.55 T — 268.32 (r2 = .96) or Ln ŷ = .065 T + 4.523 (r2 = .96). Humidity and aging had statistically significant but ecologically unimportant effects on stridulatory rates. In A. gibbosus the wing-cycle rate at low humidities (25±5% RH) was reduced to the extent expected from 0.7°C evaporative cooling. In A. dorsalis aging beyond ecological life expectancy caused an increase in tooth-strike rate and the occurrence of gaps in the tooth-strike sequence.

The reactions of the tympanal organs of the grasshopper, Tettigonia viridissima, have been investigated by recordinga ction potentials from the tympanic nerves.

The reactions are independant of the frequency of sound in the range from 1 to 100 kc/s. The organs are not capable of analysing frequencies.

The tympanal organs give phasic responses to transient components of sound of sufficient steepness (the upper and lower limits of steepness depending on incompletely understood circumstances, it could be transitory or modulations). They respond tonically to constant tones. Phasic and tonic responses are distinguised by their latencies and their activation times.

Latency of the phasic response is circa 1 ms; latency of the tonic response ca. 3.5 to 4 ms. The phasic response already appears after a single cycle of tone of 20 to 40 kc/s; the activation time of the tonic response is at least 1.25 ms (hence, at 20 kc/s, at least 25-30 cycles).

The absolute refractory period of the phasic response is 2 ms; the relative, about 12 ms. The tonic response appears in the refractory period of the two responses.

There are interactions between the two responses.

A constant tone reduces the phasic response (masking effect), but does not cause it to dissappear entirely.

The maximal modulation frequency of a tone is ca. 250 to 400 c/s. Clicks also arouse single response up to a frequency of about 400 per second.

Of the 10 Swedish species of bush crickets 9 stridulate with their elytra. The author recorded the songs of these species in their natural habitats, using instrumentation tape recorder and ultrasonic detectors. Song rhythm patterms and frequencies are presented for each species with comments on the ultrasonic components, audibility as a distance in the field with and without detectors etc. For 8 of the 9 stridulating species detectors seem to be necessary for efficient survey work and population studies in the field.

In 5 species differences found between the songs used in daytime and at night were analysed and discussed. The most important differences were found in species singing close to the ground (Platycleis denticulata, Metrioptera brachyptera, M. bicolor), whereas no corresponding difference was found in species singing from trees or high busghes (Tettigonia viridissima, Leptophyes punctatissima). The very intense songs heard at night have distinct and discrete tooth-pulses, while corresponding songs in daytime contain continuous sound waves and less conspicuous tooth-pulses in the file pulse-train. It is suggested taht this phenomenon could be something more than a mere influence of temperature on song rhythym. They could be adaptations to more efficient spread of sound waves under the acoustical conditions taht prevail above ground at night.

A perturbation experiment was carried out in which the spacing between singing male bushcrickets, Tettigonia viridissima, was artificially manipulated. The experiment entailed releasing virgin females into an area in which caged males were either spaced evenly or in which a proportion of the males were clumped. There was large variation among males in the proportion of time spent singing (range 39–91% of total singing time). Singing activity was correlated with male body weight, but was not influenced by male spacing. Out of a total of 108 females released during the experiment, the majority (N=90) moved from their release points onto the cage of one of the closest singing males. More distant signalers sometimes attracted females when one of the closest males did not sing, or sang very little, during the period in which females were moving. When clumped, males were less successful in attracting females than when regularly spaced within the experimental area. Therefore, within a homogeneous habitat in which females are randomly distributed, male mating success will be maximized when males space out as far as possible from their competitors. As predicted, a regular dispersion of signaling males is the pattern observed in the preferred microhabitats of this species in nature.

The trees constructed from different datasets were structurally similar, bisecting the six geographical populations studied. Based on two large branches in the analysis, the species Gampsocleis sedakovii was partitioned into two subspecies, Gampsocleis sedakovii sedakovii (Fischer von Waldheim, 1846) and Gampsocleis sedakovii obscura (Walker, 1869).
