Abstract:
Orthopterans have emerged as a crucial group of invertebrates for environmental monitoring and assessment. According to available literature the study of Moroccan orthopteran species remains limited in comparison to other countries. In recent years, the field of orthopteran classification has witnessed significant progress thanks to groundbreaking research in taxonomy and phylogeny that have shed new light on relationships and evolutionary history. In Morocco, there are many types of Orthoptera, including grasshoppers, crickets, and locusts, and different regions of the country have not been equally well sampled and studied. Notably the northwestern, particularly the Sidi Kacem region, are little studied. Here we present a taxonomic update of the most abundant orthopterans in Morocco based on field visits between spring and summer 2019. Five species were identified: Dociostaurus maroccanus, Aiolopus strepens, Gryllus bimaculatus, Gryllus campestris, and Nemobius sylvestris. We aim to use this publication as a baseline for future work on Orthopterans from northwestern Morocco.

Abstract:
Orthoptera is a diverse arthropod taxon that includes locusts, grouse locusts, short-horned grasshoppers, long-horned grasshoppers, katydids, crickets and mole crickets. They play crucial roles in food chains, nutrient cycling and pollination. The diversity of orthopterans in agroecosystems and grasslands located in the highlands and lowlands of Central Kerala were studied from December 2019 toMarch 2020. The study was conducted in Avoly of Ernakulam District and Venmony of Idukki District in Kerala by employing random sampling in 10 x10 m quadrats. A total of 35 species of orthopterans, belonging to two suborders, 10 families, 20 subfamilies, and 33 genera were recorded. Family Acrididae with fourteen species was the most dominant family followed by Tettigoniidae. Two species namely, Chitaura indica and Burrinia burri are endemic to the state of Kerala. It was found that the ranges of most of the orthopteran genera reported in our study extend all over the South East Asian countries. The highest number of Orthoptera was reported in December in both locations and it decreased towards March. Simpson’s diversity index value shows that both regions harbour a highly diverse orthopteran community. The diversity index value of Venmony is comparatively higher which might be due to the proximity of the study site to the natural forest ecosystem and fewer disturbances. More studies on the orthopteran fauna of Kerala are recommended which would help control their pest status and exploit their economic potential as food in animal husbandry

Abstract:
Types represent the most important specimens in natural history museums as they define a species and should usually be studied within the framework of revisions and new taxon descriptions, hence their documentation is of high importance. Orthoptera is a medium-size order of insects, but its members are important in many food chains as herbivores and as food for other animals. While the documentation of types in Orthoptera is overall very good thanks to the Orthoptera Species File site, there are still many gaps that need to be filled. The Steinhardt Museum of Natural History in Tel Aviv University holds an interesting collection of orthopterans with a focus on local endemics, which have not or only incompletely been documented in the past. Here, we provide a complete annotated catalogue of the 136 type specimens belonging to 29 orthopteran species in the Museum (SMNHTAU, historically TAU), consisting of 21 holotypes and 115 paratypes. The types of Gryllotalpa tali and Myrmecophilus wahrmani, which should be in the collection according to their original descriptions, were not found despite thorough research, and must be considered lost. This catalogue is an important resource for studies on the local fauna as well as for Orthoptera taxonomic research in general.

Abstract:
There are few studies on the Orthoptera of the floodplains, paddy fields, and levee embankments of Japan’s riparian corridors. The research which has been undertaken indicates a relatively rich fauna (33% of Japan’s grasshopper species recorded) with endangered species (e.g. Eusphingonotusjaponicus) found on gravel floodplains, although diversity is restricted by forest cover and unfavorable land uses (e.g. agriculture). Management should focus on the alteration of levee mowing regimes to benefit orthopterans, and the control of invasive plant species and successional processes along river corridors, which appears to be important for grasshoppers of gravel substrates. Integrated Green Grey Infrastructure (IGGI) measures (levee terraces of Asteraceae plants) may enhance populations of Orthoptera and conserve declining plants such as Astertripolium in Tokyo. More research is required throughout Japan to accurately determine the orthopteran fauna and appropriate conservation measures, particularly along super levees and in paddy fields.

Orthoptera from Sandakan, Sabah are relatively understudied compared to some other parts of Borneo, and lack of information of species there can impede our understanding of the origins and biodiversity of orthopterans in Borneo and, in general, Southeast Asia. Based on a recent orthopteran survey in Sandakan, one new species of Lebinthus Stål is described: Lebinthus sandakan sp. nov. The male calling song of this new species is also presented. The calling song of Cardiodactylus borneoe Robillard & Gorochov, 2014 is also described for the first time.

Abstract:
Orthoptera is a good indicator taxon of macroclimate changes. In our case study, we analyzed data of orthopterans, vegetation, and macroclimate collected yearly from 2002 through 2017 in Central European humid grasslands. During the study period, the annual mean temperature increased, while the relative abundance of moderately hygrophilic orthopteran species decreased significantly. On the other hand, the species richness and diversity of the assemblages increased due, mostly, to an increase of graminicole/thermophilic species. According to our results, the conservation of the hygrophilic orthopteran assemblages of Central European humid grasslands under global warming can only be ensured by adequate land management, which can at least mitigate the effects of climate change resulting in the warming and drying of humid habitats.

Abstract:
The Orthoptera have inhabited the Earth for ca 300 million years and today include about 25,000 described species. Although orthopterans are mainly known to the general public by their most conspicuous species such as rangeland grasshoppers, locusts, katydids and crickets, they include an amazing diversity of forms and life-styles. In this review, I bring together a series of facts about orthopteran biology that demonstrate their enormous biodiversity, concentrating on ecological and evolutionary characteristics such as habitat variation, modes of feeding, defense mechanisms and phase transformation. In a second part of this review I will consider subjects of more direct human interest as their use as food, their importance in folk medicine and their role as entertainment.

Abstract:
European flood defense embankments form an excellent habitat for Orthoptera. To be effective against storms, these vegetated earth embankments have to be managed by grazing or mowing. However, grazing can impact invertebrates such as grasshoppers and crickets (Orthoptera). This management can lead to dispersal toward undisturbed grassland and reductions in the quality of habitat, food resources and oviposition sites. In most cases, orthopteran insects require heterogeneous vegetation patches with swards of varying height. The impact of grazing depends on the type of livestock; it is very important to choose appropriate animals, timing and intensity. Sheep grazing in late summer (September-October) at a moderate intensity seems to be favorable for Orthoptera. If grazing is carefully monitored, it can promote Orthoptera conservation while maintaining flood defense integrity.

Abstract:
Orthoptera comprise an order of common insects, most of which are phytophagous, but there are also predatory orthoptera. They are found all over the world and adapt to the environmental conditions in which they are found. Orthoptera insects are pests of vegetable plants, destroying large areas, so vegetable growers are familiar with them. The research was carried out in the Amărăștii de Jos stationary in 2020 in vegetable crops. The aim of the research was to identify orthoptera species in vegetable crops and two methods were used to collect them: the beer trap method and the Barber soil trap method). Orthopteran insects were identified with the help of specialized determiners, then classified by family down to species level. Orthoptera currently identified in the stationary studied included six species, namely: Gryllotalpa gryllotalpa, Gryllus campestris, Gryllus desertus, Acrida hungarica, Dociostaurus maroccanus and Calliptamus italicus. The species with the most specimens is Gryllotalpa gryllotalpa (42 specimens) and the species with the fewest specimens is Dociostaurus maroccanus (3 specimens).

Abstract:
O pinhal constitui o tipo de floresta mais representado em Portugal, ocupando 35.5% da área florestada. Este estudo foi efectuado em pinhais e sistemas circundantes, tendo por objectivo identificar a fauna de Orthoptera, e avaliar quais os impactes ecológicos das espécies encontradas, isto é quais delas poderão constituir pragas, e quais deverão ser protegidas. Recolheram-se 60 espécies de Orthoptera, em pinhais distribuídos por seis regiões de Portugal Continental, das quais 24 pertencem à sub-ordem Ensifera e 36 à sub-ordem Caelifera, representando cerca de 50% das espécies anteriormente encontradas. Foi registado pela primeira vez em Portugal a presença de nove espécies de órtopteros, uma das quais nova para a ciência Uromenus (Steropleurus) anapaulae (G. H. Schmidt, 2002). Procedeu-se à comparação da biodiversidade de Orthoptera nos locais estudados, utilizando-se os índices de Shannon, Brillouin e Simpson. Verificou-se que os valores mais elevados, para a biodiversidade de Orthoptera, foram encontrados nos locais que apresentavam uma considerável diversidade da paisagem e diversidade de habitats, como é o caso do Parque Natural do Alvão, enquanto que os menores valores foram registados na Mata Nacional de Leiria e na Herdade da Ferraria, onde existe grande homogeneidade de habitats, constituídos quase exclusivamente por plantações de Pinus pinaster. Investigou-se qual a importância dos Orthoptera, como predadores da processionária do pinheiro Thaumetopoea pityocampa, um dos fitófagos mais importantes na região Mediterrânica, causador tanto de prejuízos económicos em pinhais como de reacções alérgicas ao Homem e outros mamíferos. Registou-se pela primeira vez, que os gafanhotos da família Tettigonidea predam sobre lagartas e imagos de T. pityocampa, além de consumirem as posturas. Em alguns pinhais verificou-se existir uma relação inversamente proporcional entre o número de tetigonídeos, e o nível de ataque do fitófago. Não se confirmou, no entanto, uma possível utilização da feromona sexual de T. pityocampa como cairomona, pelos tetigonídeos. Entre os ortópteros potencialmente causadores de pragas salienta-se a sub-espécie Locusta migratoria cinerascens, que apresenta uma distribuição circum -mediterrânica. Procedeu-se à criação laboratorial e ao estudo comparativo da bio-ecologia desta subespécie e de L. m. migratorioides, que causa prejuízos devastadores em regiões tropicais. Ambas são morfologicamente semelhantes mas ocorrem em fases diferentes, respectivamente solitária e gregária. Quantificaram-se os parâmetros reprodutivos de fêmeas virgens e copuladas das duas sub-espécies, e de fêmeas híbridas, tendo-se registado taxas de fertilidade superiores para L. m. migratorioides, denotando a sua adaptação a densidades populacionais elevadas. Obteve-se ainda, por reprodução partenogenética, 13 gerações consecutivas de fêmeas, facto que se regista pela primeira vez. Compararam-se as principais componentes das substâncias semioquímicas emitidas por fêmeas, machos e ninfas de último instar para as duas sub-espécies de L. migratoria estudadas, tendo-se verificado que existem algumas diferenças relativamente às fêmeas. Analisaram-se as respostas olfactivas a algumas das principais substâncias, nomeadamente guaiacol, veratrol, anisol, acetofenona, benzaldeído e extracto de folhas verdes, através de testes de electroantenografia, tendo-se concluído que a sub-espécie L. m. migratorioides reagiu mais intensamente às substâncias acetofenona, guaiacol e veratrol do que a sub-espécie L. m.cinerascens.

O presente trabalho teve por objetivo estudar, do ponto de vista taxonômico, as espécies de Lutosa Walker, 1869 (Orthoptera, Ensifera, Stenopelmatoidea, Anostostomatidae) que ocorrem nas florestas do leste do Estado de São Paulo, Brasil, abrangendo análises da morfologia corporal externa, do complexo fálico e espermateca. Além da re-descrição do gênero e de três espécies já conhecidas, treze novas foram descritas e uma chave dicotômica de identificação é proposta para todas as espécies examinadas. Com base na estrutura de certos elementos que compõem o complexo fálico, dois grupos de espécies foram reconhecidos e definidos. Ainda no que concerne à morfologia da genitália masculina, uma proposta de terminologia para as diferentes áreas do apódema epifálico é apresentada. Dados preliminares sobre hábitos, ecologia e comportamento de espécies de Lutosa são fornecidos.

Besides re-describing the genus and three of its valid species, thirteen new ones were described, and a dichotomic identification key for all examined species is presented. Based on the structure of certain elements that comprise the phallic complex, two species groups were recognized and defined. Still regarding male genital morphology, a terminological proposal for the different areas of the epiphallic apodeme is presented. Preliminary data on habits, ecology, and behavior of Lutosa species are given.

Le présent travail examine l'histoire évolutive d'un groupe de criquets (Insecta: Orthoptera: Caelifera), par le biais de méthodes phylogénétiques (parcimonie, maximum de vraisemblance et bayésienne) et de datation, appliquées à l'étude de séquences d'ADN nucléaire et mitochondrial combinées. Dans un premier temps, nous étudions la sous-famille Melanoplinae (Orthoptera: Acrididae) et l'une de ses tribus, Podismini, pour éclaircir leur histoire évolutive, la resituer dans un contexte paléobiogéographique, et la mettre en relation avec la taxonomie existante. Dans un deuxième temps, les méthodes de reconstruction phylogénétiques et de datation sont appliquées à l'étude de la dynamique de l'évolution concertée au sein de l'espèce Podisma pedestris, en analysant le polymorphisme intra- et interindividuels de l'ADN ribosomal, i.e. gènes et pseudogènes d'ITS1.

Abstract:
Os gafanhotos da família Ommexechidae são insetos exclusivamente neotropicais, de tamanho moderado, tipicamente achatados dorsoventralmente, com olhos protuberantes e tegumento rugoso. A família era composta, até o início deste trabalho (Ommexechidae sensu lato), por três subfamílias: Aucacridinae, com nove espécies agrupadas em quatro gêneros; Illapeliinae, com uma única espécie; e Ommexechinae, a mais diversa, com 23 espécies distribuídas em oito gêneros. O grupo foi revisado ao longo da década de 70 por Ricardo A. Ronderos, porém nunca foi estudado sob o enfoque filogenético. Este estudo teve como objetivo realizar a primeira análise cladística do grupo, utilizando caracteres exclusivamente morfológicos, de modo a testar a monofilia de todos os gêneros, das subfamílias e da própria família, e propor uma classificação supraespecífica para o grupo com base nos resultados obtidos. Como grupo-externo, foram incluídas quatro espécies de Tristiridae, uma espécie de Proscopiidae, uma de Eumastacidae, duas de Romaleidae e uma de Acrididae, e o enraizamento foi feito no nó que se ligava ao ramo terminal do proscopídeo. Dada a grande disparidade morfológica dos grupos incluídos, principalmente com relação à genitália masculina, diversas novas hipóteses de homologias precisaram ser formuladas para que a análise comparativa pudesse ser realizada. Foram examinados 681 exemplares ao total e propostas sinonímias entre algumas espécies (Ommexecha gracilis = O. brunneri e Clarazella signatifemora; Spathalium audouini = S. liebermanni; Calcitrena maculosa = Tetrixocephalus bilineatus), de modo que restaram 29 espécies como terminais para análise. Foram levantados 139 caracteres, sendo mais da metade destes referentes às genitálias masculina e feminina. Como resultado, foram obtidas duas árvores igualmente parcimoniosas, cujo consenso estrito resultou em uma única árvore com 405 passos. A árvore de consenso apresenta, de modo resumido, a seguinte hipótese de relacionamento: (Proscopiidae (Eumastacidae (Ommexechinae (Aucacridinae (Tristiridae+Illapeliinae (Romaleidae Acrididae)))))). Todos os gêneros de Ommexechidae sensu lato comportam-se como grupos monofiléticos no cladograma de consenso obtido. Contudo, é sugerida a sinonímia entre os gêneros Calcitrena (monotípico) e Tetrixocephalus, que se agrupam em um mesmo clado. As subfamílias de Ommexechidae sensu lato também formam grupos naturais, mas a família como um todo representa um agrupamento polifilético. Desse modo, são propostas algumas mudanças taxonômicas para adequar a definição dos grupos a uma classificação cladística: a única espécie de Illapeliinae é transferida para a família Tristiridae, e as subfamílias Atacamacridinae e Illapeliinae são sinonimizadas com Tristirinae; é definida uma nova família, Aucacrididae, para acomodar as espécies pertencentes até então à subfamília Aucacridinae; e a família Ommexechidae sensu Nov. passa a incluir apenas as espécies que pertenciam à subfamília Ommexechinae
Grasshoppers of the family Ommexechidae are exclusively Neotropical insects, of moderate size, typically dorsoventrally flattened, with protuberant eyes and rough integument. The family consisted, until the beginning of this study (Ommexechidae sensu lato), of three subfamilies: Aucacridinae, with nine species grouped into four genera; Illapeliinae, with a single species; and Ommexechinae, the most diverse one, with 23 species distributed in eight genera. The group was revised in the 70s by Ricardo A. Ronderos, but it had never been studied under a phylogenetic approach. This study aimed to perform the first cladistic analysis of the group, using morphological characters only, in order to test the monophyly of all genera, subfamilies, and the family itself, and propose a supraspecific classification for the group based on the results obtained. As external group, four species of Tristiridae, one of Proscopiidae, one of Eumastacidae, two of Romaleidae and one of Acrididae were included, and the rooting was done on the node that was connected to the terminal branch of the proscopid. Given the wide morphological disparity of the groups included, particularly with respect to male genitalia, several new hypotheses of homologies needed to be formulated so that comparative analysis could be performed. A total of 681 specimens was examined and synonymies were proposed between certain species (Ommexecha gracilis = O. brunneri and Clarazella signatifemora; Spathalium audouini = S. liebermanni; Calcitrena maculosa = Tetrixocephalus bilineatus), so that 29 species remained for analysis. 139 characters were coded, more than half of these related to male and female genitalia. As a result, it was obtained two equally parsimonious trees, whose strict consensus resulted in a single tree with 405 steps. The consensus tree presents, in brief, the following hypothesis of relationship: (Proscopiidae (Eumastacidae (Ommexechinae (Aucacridinae (Tristiridae + Illapeliinae (Romaleidae Acrididae)))))). All genera of Ommexechidae sensu lato behave as monophyletic groups in the consensus cladogram. However, it is suggested a synonymy between the genera Calcitrena (monotypic) and Tetrixocephalus, which are grouped in the same clade. The subfamilies of Ommexechidae sensu lato also form natural groups, but the family as a whole represents a polyphyletic grouping. Thus, some taxonomic changes are proposed to fit the definition of the groups to a cladistic classification: the single species of Illapeliinae is transferred to the family Tristiridae, and the subfamilies Atacamacridinae and Illapeliinae are synonymized under Tristirinae; a new family, Aucacrididae, is defined to accommodate the species which belonged to the subfamily Aucacridinae until then; and the family Ommexechidae is redefined as to include only those species grouped so far in the subfamily Ommexechinae

In Brazil, the order Orthoptera is poorly studied. Joint efforts among Brazilian experts achieved the approval of the project entitled Biota de Orthoptera do Brasil, to list the species present and make studies of biodiversity in different biomes in the country. The Laboratório de Bioinformática e Evolução/UFV was asked to survey the diversity, systematics and evolution of the group from molecular data. The first step was to standardize procedures to obtaining nucleotide sequences of different species of Orthoptera, from collection, through storage of material (in field and laboratory) to the standardize protocols of extraction and attainment of the amplified fragments (Appendix A). We standardized collection methodology for the preservation of DNA, and published an article with members of the Laboratório de Ortopterologia/UFV about the advantage of using fuel alcohol as a killer and preservative solution, emphasizing the reduction of costs and logistical impediments to transporting flammable substances. This article corresponds to Appendix B of this dissertation. Chapter 1, written with members of the Laborat´orio de Sistemática e Biologia de Coleoptera/UFV (LabCol), contains descriptions of eight species and one new genus from the Central Corridor of the Atlantic Forest and a complete taxonomic revision of the group, with redescriptions, including new distribution records and detailed photographs of the specimens and their structures. Still in together with LabCol, in Chapter 2 we used a molecular approach based on COI and 18S genes to establish phylogenetic relationships among species and genera collected along the Central Corridor of the Atlantic Forest, present in Chapter 1. Our results allow us to suggest the molecular description of two species and one genus, to be added to those already proposed in Chapter 1. In addition, we proposed a region of the COI gene as a DNA barcode, to assist in the diagnosis of specimens. As future prospects, we note (i) the need for new collections aimed at capturing adult males to check the propositions of new taxa, made in Chapter 2 and (ii) the need to further investigate the possibility of numts (mitochondrial sequences that migrated to the nucleus) in several species Listroscelidinae.
A ordem Orthoptera é pouco estudada no Brasil. Esforços conjuntos entre especialistas do grupo no país alcançaram a aprovação do projeto intitulado Biota de Orthoptera do Brasil, para levantamentos e estudos da diversidade em cada bioma. Ao Laboratório de Bioinformàtica e Evolução da Universidade Federal de Viçosa, coube toda a parte de levantamento da diversidade, sistemática e evolução a partir de dados moleculares. O primeiro passo consistiu em padronizar os procedimentos para obtenção de sequências nucleotídicas de diferentes espécies de Orthoptera, desde as coletas, passando pelo armazenamento do material, no campo e no laboratório, até a padronização dos protocolos de extração e obtenção dos fragmentos amplificados (Apêndice A). Da padronização da metodologia de coleta para preservação do DNA, publicamos um artigo sobre a vantagem da utilização do álcool combustível como solução matadora e preservadora, ressaltando a diminuição dos custos e impedimentos logísticos com o transporte de substâncias inflamáveis. Estes resultados foram publicados na revista Zookeys, cujo artigo, publicado em conjunto com membros do Laboratório de Ortopterologia da UFV, consta no Apêndice B. O Capítulo 1, feito em conjunto com membros do Laboratório de Sistemática e Biologia de Coleoptera (LabCol), contém descrições de oito espécies e um novo gênero provenientes do bioma Mata Atântica e uma completa revisão taxonômica do grupo, com redescrições inclusão de novos registros de distribuição e fotografias detalhadas dos espécimes e suas estruturas. Ainda em conjunto com o LabCol, no Capítulo 2 utilizamos uma abordagem molecular baseada nos genes COI e 18S para estabelecer as relações filogenéticas entre as espécies e gêneros coletados ao longo da Mata Atlântica, presentes no Capítulo 1. Nossos resultados moleculares nos permitem sugerir a descrição de duas espécies e um gênero, a serem adicionados aos já propostos no Capítulo 1. Além disso, propusemos uma região do COI como DNA Barcode, para auxiliar no diagn´ostico de espécimes. Como perspectivas futuras, ressaltamos (i) a necessidade de novas coletas visando capturar machos adultos para verificar as proposições de novos t´axons, feitas no Capítulo 2 e (ii) a necessidade investigar mais profundamente a possibilidade de existência de numts (sequências mitocondriais que migraram para o núcleo) em várias das espécies de Listroscelidinae.

Abstract:
Grasshoppers, like most other organisms, require sterols for the production of cellular membranes and, like other animals, as precursors to steroid hormones. However, grasshoppers, like other insects, cannot synthesize sterols de novo and must acquire these essential nutrients from their diets. Survival and performance of five grasshopper species, representing three phylogenetic lineages and with different host preferences, were compared on artificial diets that varied in sterol type. Sterols used were: cholesterol (Δ⁵) sitosterol (Δ⁵) stigmasterol (Δ⁵ʼ²²) spinasterol (Δ⁷ʼ²²) and lathosterol (Δ⁷); these are the most common plant sterols. For all species studied, none survived to the adult stage on stigmasterol, spinasterol or lathosterol. Performance on the cholesterol and sitosterol diets were similar for most species. This study suggests that grasshoppers, as a group, are extremely limited with respect to the sterols they can use. Grasshoppers, however, are highly polyphagous insects, often feeding on many different host-plants. Some of these host-plants contain unsuitable sterols. The effect of sterol mixtures on survival and performance was examined by rearing the grasshopper, Schistocerca americana, on artificial diets containing sitosterol (suitable) and spinasterol (unsuitable) presented either alone or in combination. Results indicated that spinasterol, even in the presence of high levels of a sitosterol, could prevent development to the adult stage. Biochemical analysis of grasshopper tissues revealed that dietary sterols with Δ⁷ and/or Δ²²-configurations could not be metabolized to cholesterol. Unmetabolized dietary sterols tended to accumulate in the midgut tissues. Grasshoppers are known to regulate feeding in response to some nutrients in relation to need. To determine if grasshoppers could regulate intake with respect to different sterols, a series of behavioral assays was performed. The grasshopper S. americana was observed feeding on artificial diets with different sterols, in some cases up to seven hours. Results suggest that S. americana developed aversion responses to diets that contained unsuitable dietary sterols (Δ⁷ and/or Δ²²) Additional experiments suggested that the aversion response developed through a combination of post-ingestive feedbacks and associative learning. Taken together, these results suggest that sterol metabolic limitations may partially determine host-plant affiliations in grasshoppers.

In this article Swedish entomologist Kjell Ander describes a novel (at the time) stridulatory apparatus in the great grig, Cyphoderris monstrosa (Prophalangopsidae), a relict ensiferan found in the mountainous regions of western North America. Ander used preserved specimens to predict the sound-producing function of a pair of abdominal file-scraper apparatuses, although he was never able to directly test his proposed mechanism nor did he speculate as to the adaptive significance of the structures. The article concludes with a review of the systematic placement of various higher level taxa within the order Orthoptera, of which Ensifera is one suborder.
