Revision of Janeirona Distant, 1911 (Hemiptera: Pentatomidae: Ochlerini) with the description of four new species from Brazil.

Janeirona Distant, 1911 is a Neotropical pentatomid genus restricted to South America that was recently transferred from Pentatominae to Ochlerini (Discocephalinae). Janeirona was described for one species, and during the 20th century other five species were allocated in the genus. In this study we redescribe Janeirona and its known species, and propose two new synonyms: Serdia stali Kormilev, 1956 as junior synonym of Janeirona insignis Distant, 1911, and Janeirona asaroana Brailovsky, 1988 as junior synonym of Janeirona costalimai (Pirán, 1962).

Heteroptera research in Latin America and the Caribbean (Insecta, Hemiptera): status and perspectives in the 21st century.

Latin American and the Caribbean regions (LAC) harbor one of the most biodiverse areas of the world, the Neotropics. True bugs (Hemiptera: Heteroptera) are a diverse lineage of insects, with more than 45,000 species, particularly speciose in the Neotropical region. True bugs are fundamental in the dynamics of natural and modified ecosystems, with several species critical to agriculture and public health.

[United in difference: on the vocation of Brazilian sociology at the Instituto Universitário de Pesquisas do Rio de Janeiro, 1973-1977].

This article investigates the first generation (1973-1977) of researchers trained in the Graduate Program in Sociology at the Instituto Universitário de Pesquisas do Rio de Janeiro (IUPERJ). While IUPERJ is known as the birthplace of modern Brazilian political science, sociology there is less well known. Using documentary resources, interviews, and the secondary literature, we take a nuanced look at this generation, which has been described as both excessively heterogeneous and less original in comparison to political science at IUPERJ.

Paropsocolis, a new pentatomid genus with two new species from Brazil (Heteroptera, Pentatomidae, Ochlerini).

When examining specimens of the Janeirona Distant, 1911 clade of Ochlerini (Discocephalinae) we found males and females of two undescribed species. Though clearly similar to the genera in the Janeirona clade, these two species lack the diagnostic characteristics of any of them. We made a cladistic analysis to verify the placement of the two new species in Discocephalinae.

Revision of Heteroscelis Latreille, 1829 (Heteroptera: Pentatomidae: Asopinae) with the description of a new species from Colombia.

The Asopinae comprises about 300 species and 63 genera of predatory stinkbugs, of which around 100 species and 23 genera occur in the Neotropical region. The species of the Neotropical genus Heteroscelis Latreille, 1829 are easily recognized by the small size, vivid and often iridescent colors, the elongated head, and the foretibial foliaceous expansions. In this work we provide a taxonomic revision of Heteroscelis.

An annotated and illustrated Type Catalogue of the predacious Shieldbugs (Hemiptera: Heteroptera: Pentatomidae: Asopinae) in the Collection of the Natural History Museum, London.

We present an annotated and illustrated type catalogue of the predacious shieldbugs (Hemiptera: Heteroptera: Pentatomidae: Asopinae), housed in the collection of the Natural History Museum, London. This work involves recognising types and their status, recording their label data and providing images of both the types and their labels. Although we personally refrain from designating lectotypes as the International Code of Zoological Nomenclature recommends that it should be done "as part of a revisionary or other taxonomic work" (ICZN 1999: Recommendation 74G), we have nevertheless accepted that lectotypes were designated before 2000 (see ICZN 1999: Art.

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.

The eggs and nymphs of predatory stink bugs (Hemiptera: Pentatomidae: Asopinae): what do we know?

The Asopinae are known for their predatory behavior, differing from the phytophagous habits of most pentatomoids, feeding mostly on soft body insects such as larvae of Lepidoptera and Coleoptera. For this reason, asopines have been studied as biological controllers in integrated pest management programs. Notwithstanding their clear relevance, the general knowledge about Asopinae has important gaps, especially regarding immature.

Bizarre morphology in extinct Eocene bugs (Heteroptera: Pentatomidae).

Newly discovered fossil bugs (Insecta: Hemiptera: Heteroptera: Pentatomidae) from the Eocene of Messel (Germany) and Green River (North America) exhibit an exaggerated morphology including prominent spiny humeral and anterolateral angles of the pronotum and a spiny lateral abdominal margin. Especially the humeral angles are unique; they consist of expansive, rounded projections with strong spines, which is a rare trait among pentatomids. A hypothesis for the function of this extreme morphology is defence against small vertebrate predators, such as birds or reptiles.

Revision of emMacropygium/em Spinola, 1837 (Hemiptera: Pentatomidae: Ochlerini) with the revalidation of three species and the description of one new species.

The Ochlerini (Discocephalinae) are endemic in the Neotropical region, and the tribe currently contains 38 genera and 149 species. The monotypic Macropygium Spinola, 1837 is the most widespread ochlerine genus in the Americas, ranging from Mexico to Argentina. Macropygium reticulare (Fabricius, 1803) is one of the few Ochlerini of phytosanitary importance, transmitting Phytomonas spp.

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.

The scent of life: Foreword from the Editors.

This special issue of Zootaxa is published in honor of Dr. Jocélia Grazia (Fig. 1) from the Universidade Federal do Rio Grande do Sul, Brazil, one of the world's most respected and influential active taxonomists in Heteroptera.

Evolutionary mechanisms for camouflage in Cladomorphus phyllinus (Phasmatodea): A reflection on the role of evidence for hypotheses proposition.

We address and discuss some of the many flaws exhibited by Costa et al. (2019) which tried to explain the twig-like camouflage of Cladomorphus phyllinus. Given the lack of both empirical and theoretical underpinnings in Costa et al.

Comparative morphology of clasping structures in predator stink bugs (Hemiptera: Pentatomidae: Asopinae): Insights into their function and evolution.

Parameres are male genital structures found in many insects which are often used as clasping devices to exert dominance in copula. The asopines have evolved a remarkable additional pair of similar structures, often denominated processes, which combines with the parameres in a tweezers-like system. Processes in similar positions have also been found in other subfamilies of Pentatomidae, but smaller and less developed.

External morphology of the abdominal glands in Asopinae (Hemiptera: Heteroptera: Pentatomidae).

Heteropterans communicate chemically through thoracic or abdominal glandular complexes. The dorso-abdominal scent glands (DAGs) are externalized by cuticular specialized structures forming the external scent efferent system (SES). Different groups in Heteroptera present other glands, such as the Asopinae (Pentatomidae), whose males can have ventral abdominal pheromonal glands externalized by cuticular modifications, called glandular patches (GPs).

Taxonomy of widespread Neotropical species of Podisus Herrich-Schäffer (Hemiptera: Pentatomidae: Asopinae): redescription of P. distinctus (Stål, 1860) and revalidation of P. fuscescens (Dallas, 1851).

Some species of Podisus Herrich-Schäffer have a confuse taxonomic history with several modifications and loss of information over time. The genus has been considered a taxonomic dumping ground in Asopinae, and its current species composition is doubtful. After examining the type specimens of Telepta distincta Stål, Arma submarginata Walker, Arma monospila Walker, Arma fuscescens Dallas, Arma caliginosa Walker, Arma turbida Walker and Podisus mellipes Bergroth, we redescribe and revalidate A.

Description of two new genera of Ochlerini (Hemiptera: Pentatomidae: Discocephalinae).

Since the phylogenetic analysis of the Herrichella clade (Ochlerini) new genera were described to fit monophyletic groups inferred and considered to be new taxa. The clade I supported by two synapomorphies of the female genitalia, grouped Alitocoris brunneus Sailer together to two new species. Alloeogyna gen.

Revision of Tynacantha Dallas with description of two new species (Hemiptera: Heteroptera: Pentatomidae: Asopinae).

Here, Tynacantha Dallas is revised and two new species are described from Brazil: T. cuprea Brugnera Grazia sp. nov.

Phylogeny and revision of Schraderiellus Rider, 1998 with the description of five new species (Hemiptera, Pentatomidae, Discocephalinae, Ochlerini).

A cladistic analysis of Schraderiellus Rider, 1998 is provided in this study. Were used 60 morphological characters for 34 taxa, including the two known species of Schraderiellus and five new species in the ingroup, two species of Discocephalini and 24 species of Ochlerini in the outgroup, and Euschistus hansi Grazia, 1987 as root. The analysis was made using TNT through heuristic searches under implied weighting of characters.

Nomenclatural changes in Ochlerini (Hemiptera: Heteroptera: Pentatomidae: Discocephalinae).

Several nomenclatural problems were found while studying the types of Ochlerini in the Natural History Museum, London. These problems are addressed and corrected: Hemingius Distant, 1899 syn. nov.

Description of four new species of Ochlerini from South America (Hemiptera: Pentatomidae: Discocephalinae).

The tribe Ochlerini Rolston was proposed in 1981 to house 23 genera of Neotropical pentatomids, most of them containing few species and poorly represented in entomological collections. After a quarter century of accumulated taxonomic knowledge the tribe totals 36 genera and 133 species, but a number of taxa still require revision or remain undescribed. Here we describe and illustrate four new species from South America, Cromata flavida sp.

Stapecolis, new genus of Ochlerini (Hemiptera: Pentatomidae: Discocephalinae).

A cladistic analysis of the Herrichela clade (Ochlerini) was conducted to solve problems concerning the systematics of the genus Alitocoris Sailer; this recovered monophyletic groups which are considered to be new genera. Stapecolis gen. nov.

Unusual looking pentatomids: reassessing the taxonomy of Braunus Distant and Lojus McDonald (Hemiptera: Heteroptera: Pentatomidae).

The Neotropical genus Braunus Distant is revised. Based on general morphology, Braunus is transferred to the Pentatominae and Lojus is proposed as a junior synonym of Braunus. The male and female genitalia of Braunus sciocorinus (Walker) are described for the first time.

Description of three new species of Glyphepomis Berg (Heteroptera: Pentatomidae: Pentatominae).

Three new species of the Glyphepomis are described: Glyphepomis dubia Campos & Souza, sp. nov., Glyphepomis amazonica Gonçalves & Campos, sp.

Candeocoris bistillatus, new genus and new species of Ochlerini from Ecuador (Hemiptera: Heteroptera: Pentatomidae).

Recent examination of specimens from Ecuador revealed a series of males and females of an undescribed species clearly belonging to the Discocephalinae. The new species presents characteristics similar to genera of both Discocephalini and Ochlerini, preventing an undoubtful placement of the new species within any genus and tribe. We conducted a cladistic analysis to investigate the possible relationships of the new species within Discocephalinae.
