Description of seven new species of Edessa Fabricius, 1803 from Central America (Heteroptera, Pentatomidae, Edessinae).

Not much is known about the Central American stink bug fauna of the Edessinae subfamily. A recent survey of Costa Rican species from this subfamily listed 65 species, of which 47 were new additions. More recently, a description of a group of species of Edessa added more three species to the fauna of Costa Rica.

Diagnose of the nominal subgenus of Edessa and descriptionof the E. sexdens group (Heteroptera, Pentatomidae, Edessinae).

The subgenus Edessa, the largest and to date the most confusing taxon of Edessa is diagnosed here, comprising 79 species listed in this work. The subgenus is characterized by the humeral angles conical, somewhat developed, and projected, with apex rounded or somewhat acuminated, but never acute, shyny and impunctate or with a few punctures. The E.

Morphology of interommatidial sensilla of Discocephalini (Heteroptera: Pentatomidae: Discocephalinae).

Interommatidial sensilla have been explored for their taxonomic value and other aspects in Diptera and Lepidoptera. In Heteroptera, Eurystethus is the only genus where these structures were examined in delimiting subgenera and species. This study investigates the presence, distribution, and morphology of interommatidial sensilla in Discocephalinae species and discusses the sensilla's value for cladistic and taxonomic appraisals.

Seventeen new Species of Hypoxys Amyot amp; Serville, 1843 (Heteroptera: Pentatomidae: Edessinae).

Hypoxys was recently raised from a subgenus of Edessa to a genus. In the same work Hypoxys was divided in four groups of species: H. quadridens; H.

A new species group to emEdessa/em, the emE. ovina/em group, with description of a new species (Heteroptera: Pentatomidae: Edessinae) from Brazil.

The E. ovina group of species is proposed here to include Edessa ovina Dallas, 1851 from Trinidad and Tobago, Colombia, Paraguay, Brazil, Argentina (new records) and Guyana; E. impura Bergroth, 1891 from Brazil and Argentina (new record); E.

Three new species of emEurystethus/em from Brazil (Hemiptera: Heteroptera: Pentatomidae).

The Heteroptera (true bugs) and its fourth-largest family Pentatomidae (stink bugs) are worldwide distributed groups with higher diversity in the tropics. The pentatomid subfamily Discocephalinae is almost restricted to the Neotropical Region, and it is divided into the tribes Discocephalini and Ochlerini. Eurystethus Mayr, 1864 is placed within Discocephalini and comprises 18 species, 16 out of them classified into two subgenera.

New cytogenetic data for three species of Pentatomidae (Heteroptera): (Dallas, 1851), (Palisot de Beauvois, 1805), and (Dallas, 1851).

In this paper, we present new cytogenetic data for three species of the family Pentatomidae: (Dallas, 1851), (Palisot de Beauvois, 1805), and (Dallas, 1851). All studied species presented holocentric chromosomes and inverted meiosis for the sex chromosomes. has 2 = 12 (10A + XY); showed 2 = 14 (12A + XY); and showed 2 = 14 (12A + XY).

Termitaphididae, a family of true bugs (Heteroptera) new to Brazil, with the redescription of Termitaradus trinidadensis.

The family Termitaphididae and the species Termitaradus trinidadensis (Morrison) are recorded for the first time from Brazil. This species had been found only in Trinidad and Tobago and is redescribed based on specimens collected in Heterotermes tenuis (Hagen) termite nests from forested and open areas in the Brazilian Amazon. Scanning electron micrographs of integumental ornamentation, illustrations of male and female terminalia, and pictures of live specimens are provided for the first time.

Description of a new group of species of Edessa Fabricius, 1803 (Hemiptera: Pentatomidae: Edessinae) with translucent spot on hemelytra.

Several species of Edessinae, especially Edessa, were described from Central America in classic and recent works; but fauna from this region still has many groups of species with remarkable characteristics to be described. One of these groups is herein described to include species with part of the corium weakly pigmented and translucent. The group E.

Revision of Hypoxys Amyot amp; Serville, 1843 stat. rest. (Heteroptera Pentatomidae).

Hypoxys is one of four subgenera of Edessa (Fabricius, 1787) together with Aceratodes (De Geer, 1773), Dorypleura (Lepeletier Serville, 1825) and Edessa (Fabricius, 1787). This taxon has a very confusing taxonomy due to incorrect use of the names available, imprecise descriptions, and large number of very similar species. To illustrate the confusion, Hypoxys potentially includes a large number of species of Edessa, but actually contains only the type species, according to the most recent catalogue.

Voragocoris weirauchae sp. n. (Heteroptera: Schizopteridae: Schizopterinae), a further minute litter bug species from Brazil.

The genus Voragocoris Weirauch, 2012 is composed of Voragocoris schuhi Weirauch, 2012 and Voragocoris amrishi Makhan, 2013, previously recorded from Peru and Suriname, respectively. In this paper, a new species, Voragocoris weirauchae sp.n.

Two new species of Hoplonannus (Heteroptera: Schizopteridae: Schizopterinae) from the Brazilian Amazon.

The genus Hoplonannus McAtee Malloch, 1925 is composed of H. brunneus, H. paenebrunneus, H.

A new species of Hypsohapsis (Heteroptera: Schizopteridae: Hypselosomatinae) from the Brazilian Amazon.

The genus Hypsohapsis Hoey-Chamberlain Weirauch was erected based on only one male specimen from southern Brazil (São Paulo). Hypsohapsis amazonica sp.n.

Revision of Pygoda Amyot Serville, 1843 stat. rest. (Heteroptera: Pentatomidae: Edessinae) with description of four new species.

Edessa is the largest genus of Edessinae and comprises five subgenera: Edessa, Aceratodes, Dorypleura, Hypoxys and Pygoda. Systematics of Edessa is very confusing due to several factors, among them, large number of species and vague diagnosis to the subgenera. In this work we continue revising Edessa elevating Pygoda to genus level based in morphological characters: pronotal angles short and acute.

Stink bugs (Hemiptera: Pentatomidae) from Brazilian Amazon: checklist and new records.

A list of the stink bugs (Pentatomidae) species of the Brazilian Amazon is provided for the first time, based on literature review and identification of the specimens of Pentatomidae deposited in the entomological collection of the Museu Paraense Emílio Goeldi (MPEG). Amazonian data base presented here has 324 species of Pentatomidae belonging to 102 genera, ten tribes and five subfamilies: Asopinae, Cyrtocorinae, Discocephalinae, Edessinae and Pentatominae. The Pentatominae has the largest number of species registered to Brazilian Amazon (144 species).

A new genus and new species of Edessinae (Hemiptera: Heteroptera: Pentatomidae).

The genus Plagaedessa gen. n. is proposed to accommodate four species: Edessa celsa Distant and three new species: P.

Reevaluation of the type species and redescription of five species of (Heteroptera: Pentatomidae: Edessinae).

In accordance with the rules in the International Code of Zoological Nomenclature, the type species for the genus Edessa Fabricius, 1803 is now recognized to be Cimex antilope Fabricius, 1798 rather than the previously recognized Cimex cervus Fabricius, 1787. Edessa antilope is redescribed, as well as the following four species that have in the past been related or compared to E. antilope: E.

Description of a new group of species of (Hemiptera: Pentatomidae: Edessinae).

The new group of species viridula is proposed to five new species: Edessa viridula sp. n., Edessa exigusternata sp.

Analysis of the karyotype structure in (Linneus, 1767): inferences about the chromosomal evolution of the tribes of Harpactorinae (Heteroptera, Reduviidae).

The subfamily Harpactorinae is composed of six tribes. Phylogenetic studies bring together some of Harpactorinae tribes, but by and large the data on evolutionary relationships of the subfamily are scarce. Chromosome studies are of great importance for understanding the systematics of different groups of insects.

Grammedessa, a new genus of Edessinae (Hemiptera: Heteroptera: Pentatomidae).

The new genus Grammedessa is here proposed for 12 species: Edessa pallicornis, E. bugabensis, E. rorativentris and E.

Chromosomal evolutionary dynamics of four multigene families in Coreidae and Pentatomidae (Heteroptera) true bugs.

Previous chromosome mapping of multigene families in Pentatomomorpha (Heteroptera) insects, which was restricted to the major rDNA, revealed remarkable conservation of number of clusters and chromosomal positions. Aiming to understand the chromosomal organization and evolutionary patterns of multigene families in karyotypes of Heteroptera, we performed a chromosomal mapping using four distinct multigene families in representatives of Coreidae (ten species) and Pentatomidae (five species). A single pair of the major rDNA cluster (18S rDNA probe) and a single pair of the minor rDNA cluster (5S rDNA probe), both terminally located were primarily observed, being, in most species, located in distinct chromosomes.

Revision of Ascra with proposition of the bifida species group and description of two new species (Hemiptera: Pentatomidae: Edessinae).

Edessa is comprised of six subgenera, Aceratodes, Ascra, Dorypleura, Edessa, Hypoxys and Pygoda. Ascra is here elevated to genus status based on characteristics of the male and female genitalia and the gibbous pronotum. This genus is comprised of eight species previously placed in Edessa-E.

New species of Edessa Fabricius, 1803 (Hemiptera: Pentatomidae) from Costa Rica.

The edessines from Costa Rica are little known; only 18 species have been registered or described from this country so far. Mainly based in a large sample from Instituto Nacional de Biodiverdidad (INBio), Costa Rica, we decided to update the information concerning Edessinae from Costa Rica. We present a list of species from Costa Rica raising the number of known species from Costa Rica to 65.

Paraedessa, a new genus of Edessinae (Hemiptera: Heteroptera: Pentatomidae).

The new genus Paraedessa is proposed, to include four species previously placed in Edessa. The new genus is characterized by males with the pygophore showing a lateral expansion of proctiger, and females with gonocoxites 8 reduced; gonapophyses 8 exposed and sclerotized. The species are very similar and their identification is possible only by comparing genitalia.
