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.Expand
The phallus in Tettigoniidae (Insecta: Orthoptera: Ensifera): revision of morphology and terminology, and discussion on its taxonomic importance and evolution.
TLDR
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. Expand
Quality calls: phylogeny and biogeography of a new genus of neotropical katydid (Orthoptera: Tettigoniidae) with ultra pure-tone ultrasonics
TLDR
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. Expand
Wing stridulation in a Jurassic katydid (Insecta, Orthoptera) produced low-pitched musical calls to attract females
TLDR
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. Expand
Acoustic, genetic and morphological variations within the katydid Gampsocleis sedakovii (Orthoptera, Tettigonioidea)
TLDR
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. Expand
Uchuca Giglio-Tos, Dectinomima Caudell and their allies (Orthoptera: Tettigoniidae: Conocephalinae)
TLDR
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. Expand
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)
Abstract The genus Aerotegmina comprises a group of African canopy-dwelling, predatory bushcrickets (katydids) that is known for its inflated tegmina and the unusually loud and low-frequency callingExpand
Description of Acoustic Characters and Stridulatory Pars Stridens of Nicrophorus (Coleoptera: Silphidae): A Comparison of Eight North American Species
TLDR
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. Expand
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 academicExpand
Biogeography, ecology, acoustics and chromosomes of East African Eurycorypha Stål species (Orthoptera, Phaneropterinae) with the description of new species
TLDR
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. Expand
Resonant Sound Production in Copiphora gorgonensis (Tettigoniidae: Copiphorini), an Endemic Species from Parque Nacional Natural Gorgona, Colombia
TLDR
The acoustic characters of Copiphora gorgonensis, a new species endemic to Gorgona Island National Park, Colombia, is described, which is closely related to C. brevicauda, a congener distributed in the Pacific rainforest of Ecuador and Colombia. Expand

Phylogeny of the Ensifera (Orthoptera): A Hypothesis Supporting Multiple Origins of Acoustical Signalling, Complex Spermatophores and Maternal Care in Crickets, Katydids, and Weta
TLDR
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. Expand
Orthopterological notes I : On the Lesini of the Leiden Museum (Tettigoniidae, Copiphorinae)
TLDR
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. Expand
Acoustic signalling in palaeotropical bushcrickets (Orthoptera: Tettigonioidea: Pseudophyllidae): does predation pressure by eavesdropping enemies differ in the Palaeo‐ and Neotropics?
TLDR
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. Expand
A Phylogenetic Analysis of the Evolution of the Stridulatory Apparatus in True Crickets (Orthoptera, Grylloidea)
TLDR
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. Expand
CONVERGENT EVOLUTION OF COURTSHIP SONGS AMONG CRYPTIC SPECIES OF THE CARNEA GROUP OF GREEN LACEWINGS (NEUROPTERA: CHRYSOPIDAE: CHRYSOPERLA)
TLDR
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. Expand
Phonotactic preferences of female meadow katydids (Orthoptera: Tettigoniidae: Conocephalus nigropleurum)
TLDR
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. Expand
Calling display and mating behaviour of Copiphora rhinoceros Pictet (Orthoptera: Tettigoniidae)
TLDR
Males of a neotropical katydid, Copiphora rhinoceros, were found to alternate stereotyped bouts of body vibration (tremulation) with an 8.7-kHz air-borne song, which is remarkable in combining vegetation-conducted transverse waves with stridulation. Expand
High ultrasonic and tremulation signals in neotropical katydids (Orthoptera: Tettigoniidae)
TLDR
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. Expand
The Determination of Parallel or Monophyletic Relationships: The Proteid Salamanders-A Test Case
TLDR
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. Expand
Specificity in the Response of Female Tree Crickets (Orthoptera, Gryllidae, Oecanthinae) to Calling Songs of the Males
TLDR
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. Expand
