“…Interestingly, none of the long-winged genera that currently occur in the Mediterranean region seem to be closely related to the short-winged Odonturini in the Southwest or the shortwinged Barbitistini in the Southeast. As concluded by several authors (Braun 2011;Naskrecki and Bazelet 2011;Grzywacz et al 2014b;Massa 2015), wing size reduction resulting in flightlessness must have occurred multiple times in the Phaneropterinae, which is supported by the recent discovery of the short-winged East African genus Peronurella HEMP, 2017, belonging to the tribe Acrometopini (Hemp et al 2017b). The conclusions of our study are in line with such a notion and support two evolutionary events within the Western Palaearctic and a probable third in South America.…”

The possession of wings and ability to fly are a unifying character of higher insects, but secondary loss of wings is widespread. Within the bushcrickets, the subfamily Phaneropterinae (Orthoptera: Tettigonioidea) comprises more than 2000 predominantly long-winged species in the tropics. However, the roughly 300 European representatives are mainly short-winged. The systematics of these radiations have been unclear, leading to their unreliable formal treatment, which has hindered analysis of the evolutionary patterns of flight loss. A molecular phylogeny is presented for 42 short-winged species and members of all European long-winged genera based on the combined data from three nuclear gene sequences (18S, H3, ITS2). We found four phylogenetic lineages: (i) the first included the short-wing species of the genus Odontura; (ii) a further branch is represented by the South-American short-winged Cohnia andeana; (iii) an assemblage of long-wing taxa with a deep branching pattern includes the members of the tribes Acrometopini, Ducetiini, Phaneropterini, and Tylopsidini; (iv) a large group contained all short-winged taxa of the tribe Barbitistini. Phaneropterinae flightlessness originated twice in the Western Palaearctic, with a number of mainly allo-and parapatrically distributed species of the Barbistini in Southeastern Europe, and the Middle East and a limited number of Odontura species in Northern Africa and Southwestern Europe. Both short-winged lineages are well separated, which makes it necessary to restrict the tribe Odonturini to the West-Palaearctic genus Odontura. Other flightless genera previously included in the Odonturini are placed as incertae sedis until their phylogenetic position can be established.

Gonatoxia helleri Hemp, 2016 is one of the most widespread bush-crickets of the genus Gonatoxia Karsch, 1889 in East Africa. This species with seven large chromosomes (2n♂ = 7) differs from other representatives of the genus Gonatoxia drastically by its reduced chromosome number, the asymmetrical karyotype including karyomorphs rarely found in tettigoniids, as well as in irregularities in the course of meiosis. To better understand the origin of such an exceptional karyotype, chromosomes of 29 specimens from four populations/localities were studied using classical techniques, such as C-banding, silver impregnation, fluorochrome double staining and fluorescence in situ hybridization (FISH) technique with 18S rDNA and (TTAGG)n telomeric probes. FISH showed many 18S rDNA loci as well as interstitial telomeric sequences, where chromosome morphology varied in these components in terms of quantity and distribution. The 18S rDNA loci coincided with active NORs and C-banding patterns. We suggest that a combination of Robertsonian rearrangements and/or multiple common tandem fusions involving the same chromosomes contributed to the formation of this karyotype/karyomorphs. The results are the first step towards a better understanding of chromosomal reorganization and evolution within the genus Gonatoxia. Low chromosome number, together with the incidence of chromosomal polymorphism that is higher in G. helleri than previously reported in bush-crickets, implies that this species can be a valuable new model for cytogenetic and speciation studies. Our findings suggest that chromosomal translocations lead to diversification and speciation in this species and could be the driving force of adaptive radiation.

“…The other possibility is that he moves, which seems less probable, especially when compared to Horatosphaga heteromorpha (Karsch). Males of this species move, sing a few times at one place and move to the next singing post (Hemp et al, 2018). P. sparsa males sing for a long period of time from one place without moving, as can be concluded from its long songs without changes in amplitude (e.g., Fig.…”

http://www.eje.cz forming behaviour in these species have recognized two basic types, one in which calling males approach acoustically responding females and one in which the females are mute and approach calling males, and there are also species in which both sexes move towards each other (e.g., Zhantiev & Korsunovskaya, 1986). Among long-winged North American phaneropterids, however, Spooner reports more complicated types of mating behaviour (reviewed in Spooner, 1995). Here the females always produce sounds, but the males use different acoustical signals. Thus, mobile males of Phaneroptera could also use other mate fi nding strategies, possibly more similar to the ancestral situation reported in long-winged tropical phaneropterines.Phaneroptera Serville, 1831 is a widespread genus with ca. 36 species occurring nearly everywhere in the tropics of the Old World (Ragge, 1956). In Europe, four species are known. P. spinosa Bey-Bienko, 1954, which occurs only in the East of the continent (westernmost point Danube
