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Frivaldszky = I. modesta intermedia Kis syn.n. The descriptions of the taxa under consideration are supplemented with unpublished morphological and/or bioacoustic data. An updated list of the taxa occurring on the Balkans includes 24 taxa (21 species, including the doubtful data on I. camptoxypha). A dichotomic and tabulated key for recognition and maps of distribution of the established taxa are presented.

Madagascar is a well-known hotspot of biodiversity. However, many Orthoptera, and especially the Tettigonioidea, belong to little-studied groups. Here we describe a new genus and species of bush-cricket reared from field-collected eggs. Paraplangia sinespeculo gen. nov., sp. nov. belongs to Phaneropterinae and shares diagnostic characteristics with members of the tribe Amblycoryphini and its African subtribe Plangiina stat. nov. Paraplangia, which has a chromosome number of 31 X0, differs from other African members of the tribe and subtribe such as Eurycorypha and Plangia, which both have 29 X0. In addition to morphology, we describe the male calling song, female acoustic response, and mating behavior. As calling song, the male produces two series of short syllables. At the end of the second series the female responds with signals of similar duration and spectral composition as the male sounds (peak about 8-9 kHz). To make future identification easier, a key to all genera of Phaneropterinae found in Madagascar is presented.

A new genus, Altihoratosphaga, is erected for species formerly assigned to Horatosphaga Schaum, 1853, and a new species is described. Four species are included in Altihoratosphaga: Altihoratosphaga nomima (Karsch, 1896), Altihoratosphaga montivaga (Sj\östedt, 1909), Altihoratosphaga nou (Hemp, 2007) and Altihoratosphaga hanangensis sp. nov. All four species are restricted to Tanzanian localities, and, except for A. nomima, for which no ecological data are available, are confined to montane forest habitats. Data on ecology, acoustics, chromosomes, and molecular relationships are provided, as well as a key to Altihoratosphaga species. The present-day distribution of Altihoratosphaga species suggests former migration events at times when wetter and colder climatic fluctuations favoured connections between montane forest communities, which today are isolated, enabling flightless taxa such as Altihoratosphaga and Monticolaria to spread.

The genus Ectadia is an East Asian genus of the tribe Elimaeini (Phaneropterinae) and is known for the complex stridulatory files of its members. The calling song was so far known from only one species, the relatively widespread Ectadia fulva. Here a new species from Yunnan, China, is described, which is morphologically similar to E. fulva except for the stridulatory file. In this character E. fulva deviates strongly from the new species and from all other Ectadia species by its high tooth number. The long lasting song (duration 30 to 60 seconds at 25\°C) of the new species is very complex and differs widely from the much shorter song of E. fulva. Its spectral composition changes during stridulation. In the new species the females respond acoustically during gaps in the final part of the male song, whereas in E. fulva they answer typically after the male song. During mating Ectadia fulva males transfer small spermatophores without spermatophylax. All of its six nymphal stages are cryptically colored. In karyotype the new species being the first studied Ectadia species is similar to the related genera Elimaea and Ducetia (all 2n=29 chromosomes in the male).

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.

We used molecular characters to infer the phylogenetic position of the Western Mediterranean bushcricket genus Odontura and to trace its high karyotype diversity. Analysis of 1391 base pairs of two mitochondrial genes (COI and ND1) and one nuclear sequence (ITS2) was conducted. Phylogenetic topologies were estimated using maximum parsimony, maximum likelihood and likelihood-based Bayesian inference. The genus Odontura is a phylogenetic outlier in respect of all other European Phaneropterinae genera and has been proposed to have originated from a hitherto unknown ancestor. Our results support the monophyly of the genus Odontura and the recognition of two subgenera: Odontura and Odonturella. We found that both Sicilian taxa of the subgenus Odontura have a completely identical morphology and song patterns. Combining these results, we proposed that both should be treated as subspecies: O. (Odontura) stenoxypha stenoxypha and O. (O.) st. arcuata. Bioacoustic data also proved to support independent markers, with song characteristics reflecting the molecular topology. Mapping the karyotypic characters onto the phylogenetic tree allows a reconstruction of the directions and transitional stages of chromosome differentiation. The number of autosomes within the genus Odontura ranges from 26 to 30. In addition to the ancestral X0 sex determination mechanism, neo-XY and neo-X1X2Y sex chromosomes have evolved independently.

The Plangia graminea complex is partly reviewed and two new species of Plangia are described, Plangia multimaculata n. sp. from savanna habitats and Plangia satiscaerulea n. sp. from the submontane zones in northern Tanzania. Plangia compressa (Walker 1869) is synonymized with P. graminea (Serville, 1838). Data on habitat, bioacoustics, and chromosomes are provided. Both analyzed Plangia species showed the same chromosomal number. Compared to other investigated African Phaneropterinae, Plangia had a reduced chromosome number and thus shows a derived condition in its genome. The sex chromosomes differed morphologically in both investigated species of Plangia suggesting different mechanisms leading to these differences. Niche specialization and the male calling song are discussed as drivers for speciation in fully alate and thus mobile taxa.

A new genus is proposed for a new East African Phaneropterinae species, Lunidia viridis, occurring on Mt. Kilimanjaro, Tanzania. Based on 33 records, notes on distribution and habitat are given, as well as acoustical data provided. Climate and vegetation parameters obtained along several transects on Mt. Kilimanjaro were evaluated describing the ecological niche of the new species. This interdisciplinary approach allows not only a profound characterisation of the ecological demands of the new genus but also predictions of the potential distribution area, which is tested for the first time for an African bush cricket species. Lunidia viridis n. gen. n. sp. occurs within humid and perhumid forests and Chagga home gardens, avoiding subhumid conditions on the mountain. It is found from 1,330 m upwards on the southern slopes, whereas the same ecological conditions are expressed from 1,930 m upwards on the drier northern slopes. Lunidia viridis has an unusually complex and variable song, which is described from field and laboratory recordings. The FISH technique for characterizing chromosomes is applied for the first time for an African species; L. viridis exhibits a karyotype typical for most Tettigoniidae.

Although Eurycorypha is the most species-rich Phaneropterinae genus in Africa, little is known about the distribution and the ecology of the species. In this study data on distribution, ecology, song and on chromosomes of some East African species are provided. The nymphs of some species are shown, famous for their ant-like appearance and behaviour. The male of E. punctipennis Chopard and three species of Eurycorypha are newly described. These are E. resonans n. sp. and E. combretoides n. sp. occurring in different habitats on Mount Kilimanjaro, and E. conclusa n. sp from forest habitats along the Tanzanian coast. Bioacoustically, the four recorded species are unusually divers, presenting non-resonant and resonant songs. As four Eurycorypha species occur syntopically on geological young Mount Kilimanjaro, the biogeographical pattern and possible speciation mechanisms in the genus Eurycorypha are discussed in context of the climatical history of eastern Africa.
