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.

A method is described for measuring the gain (i.e., the change of amplitude and phase angle) for sounds that propagate to the internal surface of the tympana in ears working as pressure difference receivers. The gain of the acoustic trachea has been measured in two similarly sized and closely related species of bushcrickets, in which the acoustic spiracles and tracheae differ markedly in size. The amplitude part of the gain is much larger in the species with the larger acoustic spiracle, whereas the phase part is very similar in the two species. The method is compared with other methods, which in the past have been used for estimating the gain of sound pathways inside animal bodies.

The Ecuadorean species Dichopetala andeana Hebard, 1924, is transferred to the new genus Cohnia. Cohnia g. nov. is characterized by short pronotum, subexagonal undivided elongated female subgenital plate, regularly up-curved and coarsely serrulated ovipositor, male simple cerci and presence in male of a structure titillators-like. Cohnia andeana comb. nov. is extensively illustrated and described, its song is presented for the first time as well as some ecological data.

It is distinct with respect to male cerci, the corresponding female basal fold, body colouration, number of teeth on the stridulatory file and the num- ber of pulses in the song. Otherwise it resembles P. propinquus in body size and general song pattern.

In this paper a combination of characters by which Poecilimon species (Orthoptera: Tettigonioidea: Phaneropteridae) can be recognised as members of the P. sanctipauli group are described. Most important are the wide fastigium, short ovipositor and song characters. The morphological characters are figured and described (Table 1), and the song patterns illustrated by oscillograms. The proposed phylogenetic relationships of the members of this group are written as [P. mytilenensis (P. pulcher, P. lodosi, P. sanc- tipauli)]. All species of the group are known from southwest Turkey and some east Aegean islands. The three species P. pulcher, P. lodosi and P. sanctipauli are morphologically and bioacoustically quite similar. P. sanctipauli and P. pulcher are distinct species, P. lodosi, however, possesses a combination of the key characters of the other two species. It may be a relict species or, in our opinion more probably, a species of hybrid origin.

The species of the Poecilimon heroicus-group occur around the Caucasus (from north-eastern Turkey to south-eastern Ukraine). We describe the diagnostic morphological characters of all these species and the male calling song of three of the four spe- cies. Based on this data the following phylogenetic relationship is derived (P. tschorochensis (P. tricuspis (P. heroicus, P. bifenes- tratus))). Within the genus Poecilimon, the species can be recognised by a relatively wide pronotum and large tegmina. In one species, Poecilimon tschorochensis Adelung, 1907 (type species of the monotypic genus Artvinia Karabag, 1962, syn. n.; P. rammei Miram, 1938, syn. n.), the tegmina are very large and the song has unusually low spectral components. This species produced di- syllabic echemes at intervals of about 10 s. In two other species of the group, P. heroicus and P. bifenestratus, the calling song of males consists of an uninterrupted dense sequence of long syllables (syllable duration around 0.5 s; ca. 1 syllable/s at 20°C). In these species the auditory spiracles are reduced in size in both sexes, and the females have extremely small tegmina and are unable to respond to the male song acoustically, which would be typical for Phaneropteridae. The change in communication from acoustically responding to mute females has not been previously documented within a group of closely related species.

In this paper a combination of characters is described by which Poecilimon species (Orthoptera, Tettigonioidea, Phaneropteridae) can be recognised as members of the P. syriacus group. All species occur in or around Anatolia – from the island of Samos in the West and the provinces of Artvin and Bitlis in the East to Jerusalem in the South. The molecular data (Ullrich 2007) suggest the following not completely resolved relationship (ersisi (syriacus, (karakushi, (angulatus, obtusicercus n. sp.)), (xenocercus, karabukensis), ((izmirensis, ege) serratus))), while P. uvarovi and P. adentatus as well as P. kutahiensis (molecular data missing) are also considered to belong to the group according to song and/or morphology. The morphological data previously used to define the group are not sufficient to recognize all of its members. Some species differed distinctly in the structure of male genitalia, but the calling songs of all species studied are characterized by an unusually high syllable repetition rate and low number of impulses per syllable. Thus the evolution of genitalia seems to be faster than that of song patterns.

Poecilimon Fischer (Orthoptera, Tettigoniidae) consists of about 130 species and a functional taxonomy of the genus re- quires arranging species into phylogenetic groups. However, this is a task that requires detailed empirical testing. This paper documents data on Poecilimon species with an inflated pronotum. The Poecilimon (Poecilimon) inflatus group is a lineage ranging along a narrow zone in the south-west corner of Anatolia and in Crete plus some other Aegean islands. By producing data of morphology and calling songs of males and responding songs of females the composition and intra- group diversity of P. inflatus group are studied. Both morphology and male calling and female responding songs, exhibited a considerable intra-group diversity. In the light of data obtained the following nomenclatural changes were made. The genus Parapoecilimon Karabağ, 1975 syn. n. is synonymised with Poecilimon Fischer and Parapoecilimon antalyaensis Karabağ, 1975 is given a new combination, Poecilimon antalyaensis (Karabağ, 1975) comb. n. Four new taxa are de- scribed in the group: (i) Poecilimon isopterus sp.n.; (ii) Poecilimon inflatus lyciae subsp. n.; (iii) Poecilimon antalyaensis myrae subsp. n., and (iv) Poecilimon antalyaensis anemurium subsp. n. The Poecilimon (P.) inflatus species group con- sists of the following species: (i) Poecilimon inflatus Brunner von Wattenwyl, 1891; (ii) Poecilimon martinae Heller, 2004; (iii) Poecilimon cretensis Werner, 1903; (iv) Poecilimon antalyaensis (Karabağ, 1975) comb. n.; (v) Poecilimon bilgeri Karabağ, 1953 and (vi) Poecilimon isopterus sp.n. The species group is defined by a combination of characters including the pronotum inflated in metazona and a male cerci mostly black in their apical 1/2–1/3. The male calling song has typically two types of short syllables and the females respond acoustically with very short latency times. By using combination of morphology and song data we suggest three main lineages in the group: (i) P. bilgeri, (ii) P. antalyaensis and (iii) the other four species.

Unisexual reproduction is a widespread phenomenon in invertebrates and lower vertebrates. If a former sexual reproducing species becomes parthe- nogenetic, we expect traits that were subject to sexual selection to diminish. The bushcricket Poecilimon intermedius is one of the few insect species with obli- gate but diploid parthenogenetic reproduction. We contrasted characters that are involved in mating in a sexually sibling species with the identical structures in the parthenogenetic P. intermedius. Central for sexual communication are male songs, while receptive females approach the males phonotactically. Com- pared to its sister-species P. ampliatus, the morphology of the hearing organs (acoustic spiracle, crista acustica) and the function of hearing (acoustic threshold) are reduced in P. intermedius. Nonetheless, hearing is clearly maintained in the parthenogenetic females. Natural selection by acoustic hunting bats, pleiotropy or a developmental trap may explain the well main- tained hearing function.

In Tettigoniidae (Orthoptera: Ensifera), hearing organs are essential in mate detection. Male tettigoniids usually produce calling songs by tegminal stridu- lation, whereas females approach the males phonotactically. This unidirec- tional communication system is the most common one among tettigoniids. In several tettigoniid lineages, females have evolved acoustic replies to the male calling song which constitutes a bidirectional communication system. The genus Poecilimon (Tettigoniidae: Phaneropterinae) is of special interest because the ancestral state of bidirectional communication, with calling males and responding females, has been reversed repeatedly to unidirec- tional communication. Acoustic communication is mediated by hearing organs that are adapted to the conspecific signals. Therefore, we analyse the auditory system in the Tettigoniidae genus Poecilimon for functional adapta- tions in three characteristics: (i) dimension of sound-receiving structures (tympanum and acoustic spiracle), (ii) number of auditory sensilla and (iii) hearing sensitivity. Profound differences in the auditory system correlate with uni- or bidirectional communication. Among the sound-receiving structures, the tympana scale with body size, whereas the acoustic spiracle, the major sound input structure, was drastically reduced in unidirectional communicating species. In the unidirectional P. ampliatus group, auditory sensilla are severely reduced in numbers, but not in the unidirectional P. propinquus group. Within the P. ampliatus group, the number of auditory sensilla is further reduced in P. intermedius which lost acoustic signalling due to parthenogenesis. The auditory sensitivity correlated with the size of the acoustic spiracle, as hearing sensitivity was better with larger spiracles, espe- cially in the ultrasonic range. Our results show a significant reduction in auditory structures, shaped by the differing sex roles during mate detection.

The species of the Isophya major-group (Orthoptera: Tettigoniidae: Phaneropterinae), are reviewed. I. major Brunner von Wattenwyl and I. mavromoustakisi Uvarov are redescribed. Two new species are described; Isophya mersinensis Sevgili & Çiplak sp. n. and Isophya salmani Sevgili & Heller sp. n. from south Anatolia. Illustrations of morphology and male calling song are provided and a detailed comparison of the four species in the group is presented. We conclude that these four species constitute a natural group in sharing male cerci with two or more denticles not ordered in a line, a character unique to this species group within the genus. From an evaluation of their morphology and song characteristics, relationships among the species in the group are I. major + (I. mersinensis sp. n. + (I. salmani + I. mavromoustakisi). Based on the the distribution pattern and habitat preference, we concluded that the division of I. salmani and I. mavromoustakisi was a vicariant event resulting from the separation of Cyprus and Anatolia due to reflooding of the Mediterranean after the Messinian salinity crisis at the beginning of the Pliocene, around 5 My ago.

A critical review of the taxonomy and systematics of the genus Isophya from the Balkan Peninsula, together with a revision of the I. modesta group, including its representatives outside the Balkans, has been made using morphological, bioacoustic and karyological data. As a result, the following taxonomic considerations have been proposed: (1) the status of two taxa has been reconsidered: Isophya rhodopensis leonorae Kaltenbach, stat.n., I. rhodopensis petkovi Peshev, stat.n.; (2) five synonymies have been established: I. hospodar (Saussure) = I. hospodar medimontana Nedelkov, syn.n.; I. plevnensis Peshev, sensu novo = I. pravdini pravdini Peshev, syn.n.; I. rhodopensis leonorae Kaltenbach = I. kisi Peshev, syn.n.; I. obtusa = I. pravdini bazyluki Peshev, syn.n.; I. modesta Frivaldszky = I. modesta intermedia Kis syn.n. The descriptions of the taxa under consideration are supplemented with unpublished morphological and/or bioacoustic data.

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.

Males of several animals, including insects, use acoustic signals to attract a sexually receptive conspecific partner. In the orthopteran chorusing genus Poecilimon (Tettigoniidae), male signalling as well as female preference can be related to male body condition and to the social environment. Song is thought to be an honest signal of male quality, and song characteristics are therefore often important for sexual and social selection. At the same time, signal expression is plastic and this plasticity depends on the quality of the individual signaller, the acoustic components preferred by females and rivals' body condition and proximity. Using the bushcricket species Poecilimon ampliatus as a model, we investigated how both internal (body condition) and external (level of competition) factors affected the expression of temporal song characteristics. We show that both factors significantly affected acoustic signalling activity: when competing against light rivals, heavy males adjusted the characteristics of their songs to different social conditions. However, light males competing against a heavy rival showed less plasticity in their acoustic signals across social conditions. During the most escalated competition, heavier males increased their acoustic signal investment up to the maximum level, signalling with longer verses and higher duty cycles, in comparison to all other treatments. Body condition and the social environment affected male acoustic signal activity, which suggests that these factors mediate the allocation of resources for signalling and different strategies adopted in competition. The adaptive plasticity of acoustic signals in this species raises new questions about the potential role that this process could play in natural choruses, where more than two competitors are signalling simultaneously.

In bush-crickets the first stage of central auditory processing occurs in the prothoracic ganglion. About 15 to 50 different auditory dorsal unpaired median neurons (DUM neurons) exist but they have not been studied in any detail. These DUM-neurons may be classified into seven different morphological types, although, there is only limited correlation between morphology and physiological responses. 97% of the stained neurons were local, 3% were intersegmental. About 90% project nearly exclusively into the auditory neuropile, and 45% into restricted areas therein. Lateral extensions overlap with the axons of primary auditory sensory neurons close to their branching point. DUM neurons are typically tuned to frequencies covering the range between 2 and 50 kHz and thereby may establish a filter bank for carrier frequency. Less than 10% of DUM-neurons have their branches in adjacent and more posterior regions of the auditory neuropile and are mostly tuned to low frequencies, less sensitive than the other types and respond to vibration. 35% of DUM show indications of inhibition, either through reduced responses at higher intensities, or by hyperpolarizing responses to sound. Most DUM-neurons produce phasic spike responses preferably at higher intensities. Spikes may be elicited by intracellular current injection. Preliminary data suggest that auditory DUM-neurons have GABA as transmitter and therefore may inhibit other auditory interneurons. From all known local auditory neurons, only DUM neurons have frequency specific responses which appear suited for local processing relevant for acoustic communication in bush crickets.

Divergence of the acoustic signals used in mate calling may be an important driver of speciation. Male song may vary accordingly to, in mismatch with or independently of female preferences. Therefore, to estimate the importance of male signal variation between subspecies, female preferences against subspecies-specific signal variants must be tested. We examined the female response probability in the two subspecies of the bush-cricket Isophya kraussii for consubspecific and heterosubspecific male signals, and also for the song of a closely related species (I. camptoxypha), which is sympatric with one, but allopatric to the other subspecies. Performing no-choice playback experiments, we found that females of both subspecies responded to the male song of their own subspecies with significantly higher probability than to heterosubspecific and heterospecific songs. Response specificity for consubspecific vs. heterosubspecific signals was not significantly asymmetric comparing the two subspecies. A significant difference was found, however, in the discrimination of heterospecific calls: females showed stronger discrimination against the song of I. camptoxypha in the subspecies sympatric with that species. Our results are best explained by a tightly covarying, stepwise coevolution of male signals and female preferences.

A new, morphologically cryptic species of phaneropterine bush-crickets is described from the grasslands of the Romanian Eastern Carpathians. Despite the morphological and acoustic similarities with the recently described Isophya nagyi Szövényi, Puskás & Orci, I. bucovinensis sp. n. is characterized by a peculiar male calling song, with faster syllable repetition rate (160–220 syllables per minute, at 22–27°C) and less complex syllable structure (composed of only two elements instead of three observable in I. nagyi). The morphological description of the new species is supplemented with an oscillographic and spectrographic analysis of the male calling song and male–female pair-forming acoustic duet. An acoustic signal-based identification key is provided for all the presently known species of the Isophya camptoxypha species group, including the new species.

The Poecilimon luschani species group (Orthoptera, Tettigonioidea, Phaneropterinae), ranging along a narrow line in West Anatolia and the Balkan mountains, has been revised using integrated data from morphology, bioacoustics, and DNA sequences of two matrilineal markers. A taxonomic approach neutral with respect to existing species/subspecies was applied to the sampled populations. The male calling song showed poor variation amongst the populations. Of the morphological structures, only the male cerci and male subgenital plate offer diagnostic characters but they are secondary gains or losses in most cases. Phylogenetic analyses applied to a data matrix consisting of concatenated 1401 bp long sequences of 16S rDNA and cytochrome oxidase subunit I produced from specimens of the group resulted in trees with similar topologies. Both genetic and phenotypic data confirmed the species status of the geographically discrete Izmir, Balkan, Aydın, Kütahya, and Balıkesir populations. However, 13 populations located in the southern part of the group's range in Antalya and Muğla Provinces of Turkey present a complex phylogenetic and morphological pattern of three morphological units, but two phylogroups. By integrating song, morphology, and phylogenetic data the following conclusions were made. The species status of Poecilimon ledereri and Poecilimon orbelicus was confirmed. The Aydın population was re-established as a valid species, P. tuncayi stat. rev. The Kütahya population was elevated to species level as Poecilimon egrigozi Ünal, 2005, stat. nov. The Balıkesir population is here described as a new species Poecilimon helleri sp. nov. The southern lineage of the species group exhibits characteristics of a chain species with three subspecies. Poecilimon luschani is retained as the species name by priority and the Poecilimon birandi is considered its subspecies as Poecilimon luschani birandistat. nov. A new subspecies Poecilimon luschani chobanovi ssp. nov. is described. The phylogenetic relationships amongst the proposed taxa are as follows: P. ledereri + (P. orbelicus + (P. tuncayi + (P. egrigozi + P. helleri) + (P. luschani luschani + P. luschani birandi + P. luschani chobanovi))).

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.

As in other phaneropterine bush-crickets, both male and female Leptophyes punctatissima can stridulate. Stridulation in the female, which had previously been overlooked, occurs in response to the male call. The main frequency of the very brief chirps is around 40 kHz. The male is stimulated to chirp more frequently by receiving response chirps from the female. Unlike most Tettigoniidae the male moves toward the female and is thus dependant on her response signal. Communication can occur over distances of at least 5 m. Some structures involved in stridulation in the female differ from that described in other phaneropterines. The insects used in these experiments were all reared in the laboratory from wild-caught parents. Between forty and fifty different insects were used at various times for laboratory studies on the song, and four different males and three females were used on the field communication experiments. The sexes were kept separate from the moult to adult or for at least 10 days before experiments.
