Two new Neotropical species of Hygronemobius Hebard were described from Brazilian Amazon: Hygronemobius duckensis sp. nov. and Hygronemobius dialeucus sp. nov. Photographs of habitus, morphological characteristics and male genitalia were provided. Calling songs and spectrograms of the new species were characterized.

A new species of the genus Oecanthus Serville, 1831 from Reserva Natural Vale, state of Espírito Santo, Brazil is described. The new species differs from other of this genus in characteristics of the pseudepiphallus main lobe, endophallic sclerites, posterior median lobe of the metanotal gland and black spots on the femora and tibiae. The chromosome number is 2n=16+XY♂=18 and 2n=16+XX♀=18, and this complement present one pair of autosomes less than the other five cytological studied species.

We characterized and compared taxonomic features of two species of tree crickets Oecanthus in tobacco plantation and adja-cent native trees and bushes at Southern Brazil. The marked differences between species included Oecanthus n. sp. with pale-green body, pale-yellow head, greenish-white eyes, file teeth number 32.8±1.2 (31–34, n = 6) and hindwings caudate. Oecan-thus lineolatus is slightly darker as pale-green, with pale-green head, yellow eyes, hind femur variegated with translucent andpale-green, file teeth number 47±2.2 (42–51, n = 18) and hindwings non caudate. Both species also differ in calling song dominant frequency and temporal parameters, as well as in the morphology of metanotal gland.

Quantificamos o intervalo de tempo das principais etapas do acasalamento e discutimos suas possíveis implicações no comportamento observado. We describe the mating behavior of Adelosgryllus rubricephalus Mesa & Zefa, 2004. In trials carried out in laboratory we verified the following mating sequence: (1) sexual recognition by antennation; (2) courtship with male turning his abdomen towards the female, performing mediolateral antennae vibration, jerking its body antero-posteriorly and stridulating intermittently, while receptive female drums on the male's abdomen tip, cerci and hind-tibia with her palpi or foretarsi; the male then stops and stays motionless for some seconds, extrudes the spermatophore and both restart the behavioral sequence described above; (3) copulation: male underneath female; with his tegmina inclined forward, and joins his genitalia to the female's to promote sperm transference ; the female steps off the male, occurring a brief end-to-end position; (4) postcopulation: without guarding behavior; male retains the spermatophore and eats it. We quantified elapsed time of each behavioral sequence and discussed its implications in the observed mating behavior.

We provide herein a description of a new species of Oecanthus collected from the tobacco plantation in southern Brazil, municipality of Sao Lourenco do Sul, State of Rio Grande do Sul. Description focused metanotal gland features, phallic sclerites, and calling song. A large sampling of individuals was distributed into four groups according to body and appendages color and dotted. We also rank all kind of marks present in the scape and pedicel. We compare linear morphometric variables of the metanotal glands and tegmina, as well as calling song parameters between groups in order do define all of them as the same species. Photographs and measurements are provided.

Although male crickets provide more informative characters for the delimitation of species and genera, many taxonomic descriptions are based only on females. This is the case for Argizala Walker, 1869 and its two valid species, A. brasiliensis Walker, 1869 and A. hebardi Rehn, 1915. We provide herein a redescription of A. brasiliensis based on a male collected in the Pampa Biome, Capao do Leao municipality, Rio Grande do Sul State, Brazil. We present photographs of epitype and male genitalia, and discuss the diagnostic features of the genus and its morphological proximity to other Pteronemobiini Nearctic genera.

The life cycle and seasonal distribution of a tropical population of Eneoptera surinamensis (De Geer, 1773) were analyzed aiming to verify whether this species life cycle is associated to the wet and dry seasons. The population studied was found at the Seasonal Alluvial Semi-deciduous Forest, Foz de Iguaçu, PR, Brazil (25º27'54.9'' S; 54º34'27.9'' W), which presents mild mesothermal and super humid climate. Field observations were made at 20- to 24-day intervals, with the first observation occurring on April 30th, 2002 and the last on April 25th, 2003. It was verified that the studied species is univoltine and cyclic with regards to the dry and wet seasons, therefore being heterodynamic and surviving the dry season as adult. O ciclo de vida e a distribuição sazonal de uma população tropical de Eneoptera surinamensis (De Geer, 1773) foram analisados com o objetivo de verificar se o ciclo dessa espécie tem associação com as estações secas e úmidas. A população analisada encontra-se na Floresta Estacional Semidecidual Aluvial, Foz do Iguaçu, PR, Brasil (25º27'54.9'' S; 54º34'27.9'' W), a qual apresenta clima mesótermico brando superúmido sem seca. As observações em campo foram realizadas em intervalos de 20 a 24 dias, sendo que a primeira observação ocorreu no dia 30/04/2002 e a última em 25/04/2003. Verificou-se que a espécie estudada é univoltina e cíclica em relação às estações secas e úmidas, sendo dessa forma heterodinâmica, sobrevivendo à estação seca como adultos.

Three isolated populations of the cricket Endecous itatibensis Rehn, 1918 had been analyzed to test the hypothesis of divergence in the calling song estridulation and to discuss its implications in the speciation process. The song registers were obtained from specimens in Corumbataí, Piraciacaba and Itatiba cities, state of São Paulo, Brazil. In the three analyzed populations, calling songs are composed by pairs of notes. Specimens from Corumbataí emit composed phrases with 3 to 18 pairs of notes, while those of Piracicaba and Itatiba have 1 to 3 pairs of notes. Inter- and intrapopulational variability in the frequencies of acoustic signals were detected. While recording the calling songs, other stridulations were registered, possibly from species of Orthoptera or Hemiptera. When the tapes were analyzed in the laboratory, it was verified that there was no overlap among the species' calling songs, in such a way that each species had their particular band of frequencies, avoiding interespecific acoustic competition. Foram analisadas três populações alopátricas do grilo Endecous itatibensis Rehn, 1918 com o objetivo de testar a hipótese de que houve divergência na estridulação de chamado e discutir as implicações no processo de especiação. Os registros sonoros foram obtidos de espécimes observados nos municípios de Corumbataí, Piracicaba e Itatiba, São Paulo, Brasil. Nas três populações analisadas, os sons de chamado são compostos por pares de notas. Foram observadas variações no ritmo de emissão dos pares de notas: E. itatibensis de Corumbataí emitem frases com 3 a 18 pares de notas e E. itatibensis de Piracicaba e Itatiba, frases com 1 a 3 pares de notas. Verificaram-se variação inter- e intra-populacional na freqüência dos sinais acústicos. Durante as gravações dos sons produzidos no processo de estridulação de chamado, foram registrados simultaneamente os sinais acústicos de outros insetos, possivelmente Orthoptera e Hemiptera. Ao analisar as freqüências destes sons em laboratório, constatou-se que estas nunca se sobrepõem, estabelecendo uma faixa particular de freqüência para cada espécie, evitando uma possível competição acústica interespecífica.

Este trabalho compara os sons emitidos por espécimens de Gryllus coletados no campus da UNESP em Rio Claro (SP), bem como a morfologia e morfometria das pars stridens, com o objetivo de aplicar os resultados no reconhecimento de possíveis espécies crípticas e contribuir na discussão de processos de especiação. Três grupos de grilos foram discriminados por diferenças nas pars stridens e sons de chamado, caracterizados por diferentes ritmos, freqüências e composição das notas, indicando assim, a presença de três espécies no local analisado, morfologicamente pouco distintas. Diante dos resultados, sugere-se a utilização das características da pars stridens e do som de chamado como caracteres diagnósticos imprescindíveis na taxonomia dos Gryllus. The Gryllus genus represents one the most complex in the Orthoptera systematic, characterized by a set of cosmopolite and cryptic species, many of them already described. This study compared the songs emitted by Gryllus specimens collected on the UNESP campus in Rio Claro (SP) and the pars stridens morphology and morphometry, to use the results to recognize possible cryptic species and contribute to the discussion of speciation processes. Three groups of crickets were discriminated by differences in the pars stridens and calling songs, characterized by different rhythms, frequencies and note composition, that indicated the presence of three species in the location analyzed, that presented few morphological differences. It is suggested from the results that the use of the pars stridens characteristics and the calling song as diagnostic traits is essential in the Gryllus taxonomy. UNESP Depto.

A new Neotropical genus of Ommatolampidinae belonging to the genus group Ommatolampae Brunner von Wattenwyl, 1893 from Brazilian Atlantic Forest was described, diagnosed, and illustrated. The description was based on the external morphology, as well as genitalia and chromosomal characterization. Muriciacris n. gen. was proposed to include Muriciacris triflavovittata n. sp. (type species) described from northeastern of Brazil, state of Alagoas.

The tropical bush cricket Eneoptera surinamensis (De Geer, 1773) shows a peculiar karyotype with 2n = 9 for males, and 2n = 10 for females, with X 1 X 2 Y♂ sex mechanism systems whose origin remains unclear, probably arisen by a two-step chromosome rearrangements, including an X acrocentric and two pair of autosomal acrocentric chromosomes (Mesa & Bran 1964; Ferreira & Cella 2006). This sex system contrasts with the less derived X0♂ found in the majority of the Orthoptera species (White 1973; Hewitt 1979).

In this paper we describe a new species of Luzarinae cricket collected from the cave “Gruta de Ubajara, municipality of Ubajara, State of Ceara, Brazil, highlighting phallic sclerites morphology and chromosome complement as diagnostic characters. We presented meiotic and mitotic characterization in order to define the karyotype with 2n = 12 + X1X2♂/12 + X1X1X2X2♀. This represents the first record of X1X20 chromosomal sex system in Gryllidae.

Two new Neotropical species of Hygronemobius Hebard were described from Brazilian Amazon: Hygronemobius duckensis sp. nov. and Hygronemobius dialeucus sp. nov. Photographs of habitus, morphological characteristics and male genitalia were provided. Calling songs and spectrograms of the new species were characterized.

Materials and Methods A new species of the genus Strinatia Chopard is described. The new species differs from S. brevipennis Chopard, the only other known species of the genus, in body color pattern, chromosome number and the structure of the male and female genitalia sclerites. Strinatia shows affinities with Eidmanacris-they both have low chromosome numbers, a reduction of the tegmina to small pads, and the absence of tibial tympanum. However, they differ in the size of the stylet, which is very short in Strinatia and elongated in Eidmanacris species, and in the shape of the distal ectophallic sclerites. [

A família Phalangopsidae, de distribuição tropical, constitui um dos maiores grupos de grilos, sendo a maior linhagem na região Neotropical. Nesta região, a subfamília Luzarinae apresenta a maior diversidade em número de espécies e adaptações ecológicas. Suas relações evolutivas, entretanto, em virtude da falta de hipóteses filogenéticas propostas para o grupo, são desconhecidas. Além disso, a terminologia empregada para a caracterização do complexo fálico é amplamente debatida. Baseando-se nesses problemas, o presente estudo teve como objetivo realizar a primeira análise cladística de Phalangopsidae utilizando caracteres morfológicos e genitais, com o objetivo de propor uma classificação supragenérica para este grupo. Uma vez que a terminologia para o complexo fálico dos grilos é debatida, foi necessário um estudo morfológico do complexo fálico com o objetivo de adequar a terminologia e propor algumas correções. Este estudo analisou o complexo fálico de grilos falangopsídeos e propôs as seguintes adequações para a terminologia genital: a presença de projeções ectofálicas ventrais em alguns táxons de Luzarinae, além da presença de uma projeção adicional em alguns grupos, como em Lerneca e gêneros próximos; a divisão da invaginação ectofálica em cinco partes: apódemas ectofálicos ventrais, arco ectofálico, projeções ectofálicas dorsais, projeções ectofálicas ventrais e dobra ectofálica; a descrição do esclerito endofálico deve considerar as projeções endofálicas medial e laterais. O estudo do complexo fálico permitiu levantar 83 caracteres genitais, os quais somados aos 59 caracteres de morfologia totalizaram 142 caracteres. A análise foi realizada com 60 espécies, sendo 5 no grupo externo e foram conduzidas buscas com pesagem igual e pesagem implicada, dos caracteres morfológicos e genitais e apenas dos caracteres genitais. As análises revelaram que Phalangopsidae e Luzarinae são monofiléticas. Além disso, baseado nos resultados de uma das análises conduzidas neste estudo, as seguintes alterações taxonômicas foram propostas para Luzarinae: o gênero Endophallusia de Mello, 1990 é considerado sinônimo júnior de Eidmanacris Chopard, 1956; a espécie Strinatia Teresópolis não foi agrupada junto às demais espécies de Strinatia e recomenda-se sua transferência para um novo gênero, a ser descrito; o gênero Endecous passa a agrupar apenas dois subgêneros, Endecous e Notendecous; propõe-se a criação de uma nova tribo, Aracambini trib. nov.; propõe-se a elevação do status de subtribo Lernecina para tribo Lernecini status nov.; e propõe-se o resgate da tribo Luzarini status nov. The Family Phalangopsidae occurs in tropical areas of the world and stands as one of the major lineages of crickets. It is considered the largest taxon of crickets in the Neotropical Region. In the Neotropics, Luzarinae comprises the most diverse taxon in number of species and ecological adaptations. However, the evolutionary relationships between its clades, due to the lack of phylogenetic hypothesis proposed, are unknown. Furthermore, the terminology employed for characterization of male phallic complex is still debated and a revision of its terms is needed. Based in these issues, this study aims to perform the first cladistic analysis of Phalangopsidae using morphological and genital characters, in order to propose a suprageneric classification for this group. Since the terminology for phallic complex is still debated, it was necessary a morphological study of the male phallic complex, improving the terminology and proposing some corrections. Thus, the following corrections are proposed: the presence of ventral pseudepiphallic projections in some Luzarinae taxa, and the presence of an additional projection in some genera, as Lerneca and its related genera; the description of the ectophallic invagination must consider its five parts: ventral ectophallic apodemes, ectophallic arc, dorsal ectophallic projections, ventral ectophallic projections and the ectophallic fold; the description of the endophallic sclerite must consider its median and lateral projections. The study of the male phallic complex allowed the proposition of 83 genital characters. The cladistic analysis was performed using 142 characters (83 genital + 59 morphology) and 60 species, five species were used as outgroups. The analysis were performed using both equal weights and implied weights for the morphological + genital characters and only genital characters. The following taxonomic alterations were made based in one of the analysis: the genus Endophallusia de Mello, 1990 is considered a junior synonym of Eidmanacris Chopard, 1956; the species Strinatia teresopolis Mesa, 1999 was not grouped with the other species of Strinatia and it is transferred to a new genus, to be defined; the genus Endecous now comprises two subgenera, Endecous and Notendecous; a new tribe Aracambini trib. nov. is proposed; the elevation of status of subtribe Lernecina to tribe Lernecini status nov. is proposed; and the tribe Luzarini is erected, Luzarini status nov.
