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.

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.

Anurans in the Rhinella margaritifera group have a long history of taxonomic confusion, mainly by morphological similarity between species and lack of acoustic and genetic data for many of the 19 described species. Herein, we presented data for Rhinella gildae based on recently collected specimens from its type locality. We provide patterns of morphological variation, measurements, advertisement and release calls and infer the phylogenetic position of R. gildae. The species geographical distribution was updated, occurring in two Amazonian localities in Maranh\ão state, and Cerrado areas in Maranh\ão and Tocantins states and also in a rainforest enclave inside Caatinga domain in Cear\á state.

Bladder grasshoppers (Orthoptera, Pneumoridae) are a unique group of nocturnal, specialized herbivores, endemic to coastal regions of Southern Africa. Adult males are characterized by an inflated abdomen, which develops at the final molt, and a signaling system capable of producing high intensity calls detectable by conspecifics at distances of up to 2 km. Female response to male calls leads to reciprocal duetting and pair formation. We have found an alternative form to the dominant inflated male tactic in three pneumorid species. These alternate males are incapable of flight and lack the air-filled abdominal bladder used in long-range acoustic communication; but may be found in copula with mature females in the field. Here we address the issue of neoteny/paedogenesis in the alternate male by comparing the morphology of inflated and uninflated adult male Bullacris membracioides with that of ultimate and penultimate nymphal instars, to determine whether these forms follow a common developmental trajectory. We then compare the behavioral responsiveness of inflated and noninflated morphs to conspecific advertisement calls, to ascertain whether alternate males have the potential to actively exploit the mate location system of duetting pairs. Morphometric analyses indicate that alternate males are a distinctly divergent form from the primary male developmental tactic. We conclude that males following the alternate tactic eavesdrop on the duets of inflated males and females to exploit the acoustic mate location system. This satellite tactic has potential impact on several aspects of pneumorid biology contributing to biasing sexual selection, sensory drive, and ultimately speciation events.

The genus Aerotegmina Hemp is common on East African mountains. Two species are known and a third, A. taitensis n. sp., is described in this paper. A. kilimandjarica Hemp is widespread while A. shengenae Hemp is endemic to the South Pare Mountains and A. taitensis n. sp. is known only from the Taita Hills. Morphologically, and from their song, A. shengenae and A. taitensis n. sp. are closely related. In chromosome number A. kilimandjarica (2n\ =\ 33) differs clearly from A. shengenae (2n\ =\ 27). Data presented on other flightless Orthoptera suggest that the South Pare Mountains and the Taita Hills, both belonging to the geologically old mountain chain of the Eastern Arc, show a faunistic similarity not shared by any other mountain range in the area. The mechanisms that led to this phylogeographic pattern in flightless Orthoptera in the Eastern Arc Mountains of northern Tanzania and southern Kenya and the inland volcanoes are discussed. A key to the three Aerotegmina species is presented, as well as bioacoustical data of all species compared to the phaneropterine species Euryastes jagoi.

This analysis is combined with sequencing of mtDNA - COI and examination of morphological traits to perform cluster analyses. 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).

The file on the right elytron may be smaller than that on the left, or absent; on either elytron it usually comprises a series of parallel ridges. The plectrum generally consists of one or more pair of setiferous tubercles, although other structures are sometimes employed. This stridulatory system ({\textquoteleft}type 1{\textquoteright}) is found in members of 14 curculionid subfamilies and in Scolytidae. Platypodidae have a similar and probably homologous organ, although the morphology of the file differs somewhat from that found elsewhere and the plectrum is a simple flange. Within Curculionidae three other elytro-tergal stridulatory systems have been found. Firstly, in some Cossoninae and Molytinae, the file is a row of tubercles on tergite VII and the plectrum is a ridge on the elytron ({\textquoteleft}type 2{\textquoteright}); this is newly reported here. Secondly, females of Ithyporini, some Camptorhinini and some Cryptorhynchini have part of the wing binding patch on tergite VII modified to act as a file, with a plectrum on the elytra ({\textquoteleft}type 3{\textquoteright}). Thirdly, some Amycterinae have a file of ridges on tergite VII and a plectrum on the elytra ({\textquoteleft}type 4{\textquoteright}), apparently an autapomorphy of a restricted group of species. In addition, some Curculionidae have a plectrum on the hind femur and a file on the abdominal sternum (some Cryptorhynchinae) or elytron (some Otidocephalinae). Scolytidae have at least three other stridulatory organs: two on the head and one involving the elytra and sternum VIII. Some systematic conclusions are drawn: the clear homology of the type 1 structures in Scolytidae and the majority of the stridulating Curculionidae indicates that the Curculionidae is paraphyletic with respect to the Scolytidae; Scolytidae should therefore be treated as a subfamily of Curculionidae. The structure of the platypodid file and plectrum provide equivocal information and do not aid resolution of the phylogenetic placement of this family. Monophyly of some Ithyporini and Camptorhinini is suggested by the distribution of type 3, but there is insufficient evidence to demonstrate paraphyly of the Cryptorhynchini. The distribution of type 2 does not indicate monophyly of the Cossoninae and Molytinae since the structures in the two are almost certainly homoplastic.
