In this study, characters distributions of genera species are discussed based on morphological analysis key to American also provided. New synonymies established: Tettigidea Scudder, 1862 = Eotetrix Gorochov, 2012 syn. nov.; Batrachidea mucronata (Saint-Fargeau & Serville, 1825) granulosa Bruner, 1913 planus (Hancock, 1907)...

Phalangopsids are a diverse group of crickets found in all tropical and subtropical regions, includes 1044 valid species. Up to now, only 22 species were studied cytologically, with the chromosome number ranging from 2n = 11 21. In this paper we chromosomes 12 phalangopsid different Brazilian biomes (eight them reported for first time), traced some trends on chromosomal derivation group, based morphology fundamental number. We that karyotype concentrates large amount metacentric chromosomes,...

There are several factors that may affect sampling with pitfall traps. Here we test the hypothesis mere walking of researcher proximate to traps could cause an increment in capture crickets. This would occur if provoked vibration litter, which crickets showed a jumping response, thus falling into We mounted 126 14 groups nine. The within group were positioned three parallel rows each, one meter apart from each other. Each nine was separated other by at least 5 m. submitted seven levels...

Stable isotope analysis (SIA) is an important tool for investigation of animal dietary habits determination feeding niche. Ideally, fresh samples should be used isotopic analysis, but logistics frequently demands preservation organisms at a later time. The goal this study was to establish the best methodology preserving forest litter-dwelling crickets SIA without altering results. We collected two cricket species, Phoremia sp. and Mellopsis doucasae, from which we prepared 70 per divided...

The morphology of the proventriculus may supply useful taxonomic characters for some species crickets. This study evaluated if can be used to distinguish three Nemobiinae crickets: Phoremia sp. n., Zucchiella and Amanayara sp n. In crickets presents six lobes, each one bearing eight appendices along its longitudinal axis. central portion first appendix has a tooth like spear, with two denticles; second plate formed by five denticles, whereas in apex is U-shaped denticles absent, differ from...

Here we describe a new genus and two species of Luzarinae crickets (Grylloidea, Phalangopsidae) from the Brazilian Atlantic Forest Espírito Santo, Minas Gerais Rio de Janeiro States (Brazil). We Pizacris Souza-Dias & Desutter-Grandcolas, n. gen., transfer Mellopsis zefai Mews Sperber, 2010 to P. (Mews 2010) comb., redescribe this based in topotypes and, since type series is lost, designate neotype. also second genus, carioca Desutter-Grandcolas sp. The characterized by dark brown uniform...

Amanayara de Mello & Jacomini, 1994 was described with two species, both from Atlantic Forest remnants, in São Paulo State, Brazil. Here we describe three new species (Amanayara ribasi sp. nov., bernardesi helenae nov.) forest remnants Minas Gerais This is the first record of this genus for Gerais. We present a key genus, thorough illustration genitalia morphological characters used key. Together descriptions also distribution map, photograph types, female terminalia and comparative male...

Lophotettiginae is a small, peculiar taxon of the Neotropical region, characterized mainly by median carina compresso-cristated or leaf-like crest, antennae flattened laterally and expanding from base to apex (incrassate shape). This subfamily has only one genus known as Lophotettix Hancock, 1909 that comprises five species. Here, we reviewed types species, highlighting morphological aspects distinguish species each other tetrigids. Additionally, also provide pictorial identification key Our...

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

The tribe Cleostratini Bolívar, 1887 sensu Storozhenko, 2016 does not represent a monophyletic taxon because it gathers various Tetrigidae genera with types of horn and prolongation frons or vertex. Prolongation these structures is present in morphologically biogeographically distant groups. We do regard Miriatrini Cadena-Castañeda & Cardona, 2015 synonymous the genus Miriatra 1906 belongs to group from Cleostratus Stål, 1877. There no adequate diagnosis for proposed groups forming tribes...

Identification Orphulellini grasshoppers (Acrididae: Gomphocerinae) species has been difficult due to high polymorphism rate. Orphulella Giglio-Tos, 1894 is a genus with widespread geographical distribution and poor descriptions. punctata (De Geer, 1773) an extensive record of occurrence available information about the phallic complex, however, there data describing other parts male reproductive tract. The objective this study was characterizes internal organs system spermatozoa O. punctata....

It consists of two genera: Amorphopus Seville, 1838 and Eomorphopus Hankock, 1907 with three Neotropical species: notabilis Serville, 1838, antennatus (Bolívar, 1887), granulatus Hancock, 1907. Two species are transferred from to the genera Metrodora Bolívar, 1887 Crimisus 1887, new combinations proposed: gibbosula (Walker, 1871), comb. nov. humeralis New synonyms = griseus syn. ; 1871) Platytettix reticulatus 1906, Allotettix bolivianus...

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

In work we describe two new Phoremia (Phoremia zefai sp. nov. and rolfsi nov.) one Zucchiella (Zucchiella matiottiae nov.), found Atlantic Forest remnants We present key Brazilian species, complete illustrations genitalic morphological characters used key. Together descriptions three also...

The mole crickets Neoscapteriscus borellii (Giglio-Tos) and tenuis (Scudder) (Orthoptera: Gryllotalpidae) are recorded for the first time in Bahia State, Brazil tobacco (Nicotiana tabacum L. [Solanaceae]) plantations. Insects were collected using pitfall traps plantations municipalities of Cruz das Almas, Governador Mangabeira, Muritiba, Bahia, Brazil. presence nymphs adults these species suggests that may threaten productivity due to root damage caused by excavation and/or feeding...

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

Herein we describe a new species of Copiocerinae, Zygoclistron ruschii Silva n. sp., from Atlantic Forest remnants in southeastern Brazil, collected the Reserva Biológica Augusto Ruschi Santa Teresa municipality, Espírito Santo state, Brazil. The diagnosis this is based on phallic complex and terminalia characters.
