A cladistic analysis and systematic revision of the genus Panacanthus accompanies the description of three new species, with calling songs reported for four species. [] Key Result Phylogenetic analysis produced one most parsimonious cladogram eighty-two steps long, with the ensemble consist- ency index ¼ 0.84. Panacanthus cuspidatus and P. pallicornis (formerly Storniza Walker 1869, Martinezia Bolivar 1881) are properly incorporated in Panacanthus.

The phallus in Tettigoniidae (Insecta: Orthoptera: Ensifera): revision of morphology and terminology, and discussion on its taxonomic importance and evolution.

The exoskeletal morphology of the phallus in katydids, its components, and revised the terminology for them are studied, and potential functional relationships based on hypothetical morphological correlations between the shape of titillator and cerci are proposed.

Quality calls: phylogeny and biogeography of a new genus of neotropical katydid (Orthoptera: Tettigoniidae) with ultra pure-tone ultrasonics

Biogeographic analysis indicates that such genetic divergence began with geographic isolation produced before the Holocene transgression, suggesting a recent genetic divergence in this new genus of tropical katydid.

Bizarre morphology in extinct Eocene bugs (Heteroptera: Pentatomidae)

Phylogenetic analyses using parsimony as well as Bayesian algorithms confirmed that the new genus from the Eocene of Messel and Green River is a member of Pentatomidae, but could not solve its phylogenetic relationships within Pentatomids.

Wing stridulation in a Jurassic katydid (Insecta, Orthoptera) produced low-pitched musical calls to attract females

Providing an accurate insight into paleoacoustic ecology, the low-frequency musical song of A. musicus was well-adapted to communication in the lightly cluttered environment of the mid-Jurassic forest produced by coniferous trees and giant ferns, suggesting that reptilian, amphibian, and mammalian insectivores could have also heard A.Musicus' song.

Acoustic, genetic and morphological variations within the katydid Gampsocleis sedakovii (Orthoptera, Tettigonioidea)

An analysis of the genetic, calling songs, and morphological variations within the species Gampsocleis sedakovii from Inner Mongolia, China provides evidence for insect acoustic signal divergence and the process of subspeciation.

Uchuca Giglio-Tos, Dectinomima Caudell and their allies (Orthoptera: Tettigoniidae: Conocephalinae)

Both genera appear to be closely related monophyletic groups, as previously thought, but they are mem bers of a larger generic complex, incorporating the genus Paranelytra and sev eral undescribed genera from the New World.

Extremely divergent song types in the genus Aerotegmina Hemp (Orthoptera: Tettigoniidae: Hexacentrinae) and the description of a new species from the Eastern Arc Mountains of Tanzania (East Africa)

The songs of another two species of the genus Aerotegmina are described which are much larger than the type species and have an even lower peak frequency.

Description of Acoustic Characters and Stridulatory Pars Stridens of Nicrophorus (Coleoptera: Silphidae): A Comparison of Eight North American Species

A phylogeny is constructed for the Nicrophorine burying beetles based on the morphology of the stridulatory structures and the acoustic characters, and found weak support for an intraspecific signal divergence model.

Singers in the grass: call description of conehead katydids (family: Tettigoniidae) and observations on avoidance of acoustic overlap

ABSTRACT The sub-family Conocephalinae constitutes one of the richest groups of katydids in terms of diversity and distribution. Tropical katydids especially in India have largely escaped academic

Biogeography, ecology, acoustics and chromosomes of East African Eurycorypha Stål species (Orthoptera, Phaneropterinae) with the description of new species

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.

Phylogeny of the Ensifera (Orthoptera): A Hypothesis Supporting Multiple Origins of Acoustical Signalling, Complex Spermatophores and Maternal Care in Crickets, Katydids, and Weta

Numerical analyses of orthopteroid insects indicate that the Ensifera is a natural group as taxa in this suborder appear to form a separate clade (monophyletic group) in both cladistic and phe- netic analyses.

Orthopterological notes I : On the Lesini of the Leiden Museum (Tettigoniidae, Copiphorinae)

When rearranging a part of the collections of Orthoptera in the Rijksmuseum van Natuurlijke Historie at Leiden I found a number of specimens belonging to this tribus, which by former authors is considered as a separate subfamily with the name Eumegalodontinae, it is justified to let it retain its place as a tribe of the Copiphorinae.

Acoustic signalling in palaeotropical bushcrickets (Orthoptera: Tettigonioidea: Pseudophyllidae): does predation pressure by eavesdropping enemies differ in the Palaeo‐ and Neotropics?

None of the various types of bat avoidance behaviour observed in the neotropical Pseudophyllidae was found in the Malaysian species, and the possibility of different predation pressures in the Palaeo- and Neotropics is discussed.

A Phylogenetic Analysis of the Evolution of the Stridulatory Apparatus in True Crickets (Orthoptera, Grylloidea)

Phylogenetic analysis reveals an unsuspected complexity in the evolution of acoustic communication in crickets, and indicates that the loss of the stridulum could be reversible, and that several modalities of evolutionary change exist for thestridulum.

CONVERGENT EVOLUTION OF COURTSHIP SONGS AMONG CRYPTIC SPECIES OF THE CARNEA GROUP OF GREEN LACEWINGS (NEUROPTERA: CHRYSOPIDAE: CHRYSOPERLA)

The first well‐documented case of convergence in songs among related species living on different continents is presented, in a group of sibling, cryptic species characterized by substrate‐borne vibrational mating songs.

Phonotactic preferences of female meadow katydids (Orthoptera: Tettigoniidae: Conocephalus nigropleurum)

Sexually receptive females of Conocephalus nigropleurum were tested in an arena at 30 °C for responsiveness to tape-recorded models of male calling song, indicating that discriminatory criteria change with particular combinations.

High ultrasonic and tremulation signals in neotropical katydids (Orthoptera: Tettigoniidae)

Eavesdropping by predatory bats offers the most plausible selective explanation for the features of M. speciosum's signal system, supported by the species' sexually dimorphic defensive spination: males, the sound-signalling sex, have metafemoral spines of greater size and distinctive orientation.

The Determination of Parallel or Monophyletic Relationships: The Proteid Salamanders-A Test Case

It is concluded that Proteus and Necturus are probably not derived from a common ancestor which was a perennibranchiate salamander and there is no morphological, paleontological, or biogeographical evidence to favor either of these hypotheses over the other.

Specificity in the Response of Female Tree Crickets (Orthoptera, Gryllidae, Oecanthinae) to Calling Songs of the Males

On late summer evenings in many habitats in the eastern United States, there are twenty or more species stridulating at the same time, and the resulting din is astonishing to those unaccustomed to it.
