Phylogeny, divergence times, and evolution of Oecanthidae n. status (Insecta, Orthoptera, Grylloidea

A ordem Orthoptera, conhecida principalmente pelos grilos e gafanhotos, é distribuída mundialmente com quase 30 mil espécies válidas, sendo considerada a ordem mais diversa dentre os Polyneoptera. Em Orthoptera, os grilos verdadeiros (Grylloidea) são organismos frequentemente utilizados como organismos modelo para diversos tipos de estudo como comunicação acústica, comportamento, ecologia e até neurobiologia. No entanto, poucos desses estudos são focados no contexto evolutivo, uma vez que ainda existem poucas hipóteses filogenéticas para o grupo. Além disso, a comunicação acústica desses insetos é considerada um dos elementos mais intrigantes e presentes em sua evolução. Porém, apesar de ser um tema constantemente retratado pela comunidade científica, poucos trabalhos o abordam em um contexto filogenético. No primeiro capítulo dessa tese, apresentamos uma hipótese filogenética para uma nova família de grilos, grupo-irmão de Gryllidae n. def.: Oecanthidae n. status. As análises filogenéticas possuem como fonte de caracteres dados moleculares e morfológicos, para parcimônia e máxima verossimilhança, e dados moleculares para a análise de tempos de divergência (inferência bayesiana). Foram utilizados 107 terminais de todas as regiões biogeográficas e seis fósseis para a calibração da árvore filogenética. Todas as análises resultam em Oecanthidae n. status composta por quatro subfamílias, Euscyrtinae, Oecanthinae n. def., n. status, Podoscirtinae n. def. e Tafaliscinae n. def. n. status. Baseado nos resultados obtidos, nós revisamos a definição e a classificação interna das subfamílias, supertribos (propostas neste trabalho) e tribos. Phyllogryllini n. tribo é definida. Também atualizamos as diagnoses, listamos os gêneros de cada uma das tribos e as apomorfias dos táxons supragenéricos. Também é apresentada uma chave de identificação para todos os níveis taxonômicos de Oecanthidae n. status mais todos os gêneros de Tafaliscinae n. def. n. status. No segundo capítulo, utilizamos a filogenia de Oecanthidae, baseada em dados moleculares e morfológicos, para realizar uma reconstrução de estados ancestrais relacionados a comunicação acústica. Os caracteres são estruturas das asas anteriores, as próprias asas anteriores e tímpanos. Foram analisados seis caracteres no total. Nossos resultados demostram perdas de caracteres relacionados a comunicação acústica para vários táxons independentemente ao longo do tempo. Ao final, discutimos as possíveis causas da perda da capacidade de produção do som em Oecanthidae além das suas alternativas para uma comunicação eficiente não dependente de sinais acústicos.Orthoptera, mainly known by crickets and grasshoppers, is distributed worldwide with almost 30,000 valid species. The order is considered the most diverse order within Polyneoptera. In Orthoptera, true crickets (Grylloidea) are frequently used as models for many areas of science as acoustic communication, behavior, ecology, and neurobiology. However, only a few studies are focused on a phylogenetic context since the number of phylogenetic hypotheses for this group is low. Besides, the acoustic communication of these insects is considered an essential element of their evolution. Although it is a subject constantly debated, only a few works are in a phylogenetic frame. In the first chapter of this thesis, we present a phylogenetic hypothesis for a new family of crickets, sister-group of Gryllidae n. def.: Oecanthidae n. status. The phylogenetic analyses are based on molecular and morphological data for maximum likelihood and parsimony criteria and molecular data for divergence times analysis (Bayesian inference). Were used 107 terminals from all biogeographic regions and six fossils to calibrate the phylogenetic tree. All analyses result in Oecanthidae n. status composed of four subfamilies: Euscyrtinae, Oecanthinae n. def., Podoscirtinae n. def., and Tafaliscinae n. def. n. status. We revise the definition and internal classification of subfamilies, supertribes (proposed herein), and tribes based on our results. Phyllogryllini n. tribe is defined. We also update the diagnosis of suprageneric groups, list their apomorphies, and list the genera of each tribe. An identification key is proposed for all taxonomic levels of Oecanthidae n. status plus all Tafaliscinae n. def., n. status genera. In Chapter 2, we use the phylogeny of Oecanthidae, based on molecular and morphological characters, to reconstruct the history of characters related to acoustic communication in crickets as forewings structures, the forewings itself, and tympana. In total, the history of six characters are analyzed. Our results demonstrate the loss of characters related to acoustic communication along the time independently for many taxa in this family of crickets. Several of these taxa are not able to use forewings to stridulate. We discuss the potential causes of losing the capacity of sound-producing and hearing and their alternatives for efficient communication not exclusively based on sounds

Taxonomic and phylogenetic study of Eidmanacris Chopard, 1956 (Orthoptera; Phalangopsidae; Luzarinae)

Os ortópteros neotropicais, com exceção aos de importância econômica, de maneira geral, são muito pouco conhecidos em relação aos demais ortópteros ao redor do mundo. Isso devido à carência de trabalhos científicos para esse grupo, principalmente os estudos taxonômicos; consequentemente, o número de espécies descritas atualmente é muito subestimado. Não diferente, o gênero Eidmanacris Chopard, 1956, possui atualmente 20 espécies descritas, distribuídas nos domínios de Mata Atlântica e Cerrado, que se estendem pelas regiões sul, sudeste e centro-oeste brasileiras, além de também serem encontrados na Bolívia e Paraguai. São grilos ativos no período noturno, habitantes cavidades naturais, como tocas, barrancos, troncos de árvores mortas, fendas de rochas e cavernas. Neste estudo, o gênero foi revisado, incluindo a redescrição de espécies pouco conhecidas, descrição de sete novas espécies (E. scopula Campos, sp. nov., E. gigas Campos, sp. nov., E. neomarmorata Campos, sp. nov., E. desutterae Campos, sp. nov., E. putuhra Campos, sp. nov., E. fontanettiae Nihei & de Mello, sp. nov. e E. melloi Campos, sp. nov.), três novas combinações (E. speluncae (Mello-Leitão, 1937) comb. nov., E. minuta (de Mello, 1990) comb. nov. e E. endophallica (de Mello, 1990) comb. nov.) e uma sinonímia nova (E. lencionii Bolfarini, 2016 = E. dissimilis Desutter-Grandcolas, 1995, syn. nov.), totalizando 29 espécies para o grupo. Também foram feitos uma chave de identificação para o gênero e mapas de distribuição de suas espécies. Uma análise filogenética é apresentada incluindo 38 terminais, dos quais 12 foram considerados como grupo externo, e 98 caracteres morfológicos. Essa análise suportou a monofilia do gênero, permitiu visualizar seu relacionamento com táxons próximos de Luzarinae e sustenta a proposta de sinonímia de Endophallusia de Mello, 1990 com Eidmanacris Chopard, 1956, de modo a sua taxonomia refletir a monofilia indicada na análise filogenéticaThe Neotropical Orthoptera, excluding those with economic importance, are poorly known, in comparison with the orthopterans around the world. The main reason is the lack of scientific studies on this group, mainly taxonomic studies, resulting in a underestimated number of described species. Likewise, Eidmanacris Chopard, 1956 comprises 20 described species, and is mostly distributed on Atlantic Forest and Cerrado areas, extending from south, southeast and midwest Brazilian regions, and beyond, reaching Bolivia and Paraguay. Eidmanacris species are active at night, and inhabit natural cavities as burrows, bounds, hollow trees trunks, cavities in rocks and caves. In this study, the genus was reviewed, including the redescription of seven new species (E. scopula Campos, sp. nov., E. gigas Campos, sp. nov., E. neomarmorata Campos, sp. nov., E. desutterae Campos, sp. nov., E. putuhra Campos, sp. nov., E. fontanettiae Nihei & de Mello, sp. nov. and E. melloi Campos, sp. nov.), three new combinations (E. speluncae (Mello-Leitão, 1937) comb. nov., E. minuta (de Mello, 1990) comb. nov. and E. endophallica (de Mello, 1990) comb. nov.) and one synonym (E. lencionii Bolfarini, 2016 = E. dissimilis Desutter-Grandcolas, 1995, syn. nov.), totalizing 29 species in this genus. An identification key for the genus and a distribution map of species were made. A phylogenetic analysis is presented including 38 terminals, 12 of them as outgroup and 98 morphological characters This analysis attested the monophyly of the genus, showed its relationships with another Luzarinae taxa, and supported the proposal of synonymy of Endophallusia de Mello, 1990 with Eidmanacris Chopard, 1956, so that its taxonomy reflected the monophyly indicated in the phylogenetic analysi

Taxonomic studies on the Neotropical Landrevinae with description of new taxa (Orthoptera, Grylloidea, Gryllidae)

The understanding of the subfamily Landrevinae has been modified by different authors since its creation. In the neotropics three genera are known to the present: Odontogryllus Saussure, 1877 (one from México, the others amazonian), Brasilodontus de Mello, 1992 with two species (from Brazilian Atlantic Forest), e Valchica de Mello, 1992 with one species (from Costa Rica). De Mello (1992) erroneously created the tribe Odontogryllini for this cluster of neotropical genera, here suppressed. In the present paper we revise and add new species to Brasilodontus and describe two monotypic genera, Xulavuna n. gen. and Yarrubura, n. gen. An identification key to the genera of neotropical Landrevinae is presented as well as one for the species of Brasilodontus. The male fore wings of Xulavuna adenoptera n. sp. is remarkable regarding its shape and its glandular conditionO entendimento da subfamília Landrevinae tem sido alterada por diferentes autores desde sua criação. Até o momento, três gêneros são conhecidos da Neotropica: Odontogryllus Saussure, 1877 com 11 espécies (uma das quais do México, as demais amazônicas), Brasilodontus de Mello, 1992 com duas espécies (da Floresta Atlântica brasileira), e Valchica de Mello, 1992 monotípico (da Costa Rica). De Mello (1992) erroneamente erigiu a tribo Odontogryllini para esse grupo de gêneros neotropicais, aqui suprimida. No presente trabalho revisamos e adicionamos novas espécies ao gênero Brasilodontus e descrevemos novos gêneros monotípicos, Xulavuna gen. n. e Yarrubura, gen. n. Uma chave de identificação para os gêneros de Landrevinae neotropicais é apresentada, assim como uma para as espécies de Brasilodontus. As asas mesonotais do macho de Xulavuna adenoptera sp. n. são notáveis quanto à forma e sua condição glandula

REMARKS The holotype (female) of Pseudogryllus elongatus Chopard, 1912 and specimens collected close to its type locality were analyzed (male and female). This species has all the diagnostic characters of Tafalisca, and there are no remarkable characters to support the genus Pseudogryllus Chopard, 1912. Thus, Pseudogryllus is considered a junior synonym of Tafalisca. The subspecies Tafalisca elongata gigas (Gorochov, 2011) from Colombia was also described by a single female. Because of the geographical distance and the diversity of Tafalisca genus, both subspecies probably correspond to different species. However, without at least the description of the copulatory papilla of T. elongata gigas, it is not possible to compare both taxa properly and propose taxonomic rearrangements. Holotype images and more information of Pseudogryllus elongatus Chopard, 1912 are available in MNHN collection website (http://coldb.mnhn.fr/catalognumber/mnhn/eo/ensif6594).
