Exploring Phylogenetic Relationships of the Mecocephala Group (Hemiptera: Pentatomidae) Using Continuous and Discrete Characters, with Notes on Taxonomy.

The Mecocephala group comprises about 50 species, restricted to the Neotropics and with the highest species richness in Neotropical South America. Several species use rice as host plants and their identification is facilitated by the presence of exaggerated head proportions and a unique male genitalic morphology. The taxonomy of the group has been extensively explored, but inferring its monophyly and especially its internal phylogenetic relationships has been challenging.

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.

The Impact of Life Philosophy and Major Field of Study on Brazilian Students' Knowledge of Biological Evolution.

Unlabelled: Evolutionary theory (ET) is the unifying theory of Life Sciences, but it is largely misunderstood and the target of dispute in many countries, mainly because of conflicts with religious beliefs. Brazil is a country with a culture that is deeply rooted belief in God. In this paper, we report a study in Brazil where we applied a 12-question questionnaire to understand the relationship among the major field of study and the self-declared religious and philosophical context on the knowledge of evolutionary theory by Brazilian freshmen.

Taxonomic updates on the Mecocephala group (Hemiptera: Pentatomidae): Redescription of 'Hypatropis complex', with a review of genitalic terminology and new records.

The taxonomic revision of 'Hypatropis complex', composed by Amauromelpia Fernandes Grazia, Hypatropis Bergroth, Luridocimex Grazia, Fernandes Schwertner, Stysiana Grazia, Fernandes Schwertner, and Pedinonotus Fernandes Grazia, updating the genitalic terminology, are presented here. The differential diagnosis of 'Hypatropis complex' and all of its members are provided. Photographs of the type-specimens and genitalia, species distributional map with new records, and a key to genera and species are also provided.

A milestone for Pentatomoidea: Grazia emet al./em 2008-What do we know and where can we go?

Pentatomoidea is the third largest superfamily in Heteroptera. The internal systematics and classification of this superfamily have an intricate history. The paper by Grazia et al.

Redescription of Steleocoris Mayr, 1864 and Theloris Thunberg, 1783 (Hemiptera: Pentatomidae), two poorly known African stink bugs.

The knowledge about the monotypic genera Steleocoris Mayr and Theloris Thunberg is restricted to their original descriptions and subsequent nomenclatural acts. These genera are primarily distributed in South Africa and are two of the few genera of Carpocorini (Pentatomidae: Pentatominae) occurring in Africa. Here, we redescribe Steleocoris comma (Thunberg) and Theloris costata (Thunberg) and illustrate the genitalia of both sexes for the first time.

New species and new distributional records of Elanela Rolston, 1980 (Heteroptera: Pentatomidae).

Two new species are described, Elanela colombiana sp. nov. from Colombia, with disk of scutellum callused, ivory and abdominal sternite VIII immaculate medially, and Elanela ecuatoriana sp.

Stink bugs (Hemiptera, Heteroptera, Pentatomidae) of the Catimbau National Park, a protected area in Brazil's largest dry forest.

The knowledge about insects of the Caatinga, the largest seasonally dry tropical forest of South America, is largely incomplete. Aiming at reducing this knowledge gap, we conducted the first inventory of Pentatomidae (Hemiptera: Heteroptera) for the Catimbau National Park and Pernambuco State. After 48h of sampling, during dry and rainy seasons, we collected 168 specimens, comprising 12 species and 10 genera of Pentatomidae.

Synonymy of two important crop pests of burrower bugs, Cyrtomenus mirabilis and C. bergi (Hemiptera: Cydnidae), based in a multi-source approach.

Burrower bugs are unique among true bugs, recognized by the morphological adaptations for digging, and include several species of economic importance for causing damages in roots and ground pods. Damage records has been growing in the last two decades in the Neotropics, but taxonomic problems still hampers studies in these group of insects. Cyrtomenus bergi Froeschner and C.

Immature stages of Murgantia histrionica (Hemiptera: Pentatomidae).

Immature stages of Murgantia histrionica (Hemiptera: Pentatomidae) are described using light and scanning electron microscopy. Specimens of all life stages of M. histrionica were collected on Peritoma arborea (Cleomaceae) in Palm Springs, California.

Review of the group of (Pentatomidae: Pentatominae: Carpocorini) with description of the internal female genitalia and a new species.

Euschistus Dallas is comprised of 66 species in three subgenera. Species of the nominate subgenus occur mainly in Central and North America. Some groups of species have been proposed to Euschistus (Euschistus) based on general external and male genitalic morphologies.

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.

There and back again: contributions on Pseudevoplitus Ruckes (Heteroptera: Pentatomidae).

Pseudevoplitus Ruckes was recently revised and new species were described. The genus has a Neotropical distribution, with species mainly found in the Amazon. Here, we describe the previously unknown female of P.

Revision of Urubaxia Fennah (Hemiptera: Cercopidae: Ischnorhininae) with description of two new species.

We reviewed Urubaxia Fennah, 1968 and described two new species, Urubaxia solo n.sp. and Urubaxia chewie n.

Elanela Rolston revisited (Heteroptera: Pentatomidae): new distributional records and description of new species.

Menidini is highly diverse in the Paleartic and Afrotropical regions. Only two genera, Rio Kirkaldy and Elanela Rolston, are currently known from the Neotropical region. Here we describe five new species of Elanela: E.

Comparative morphology of selected characters of the Pentatomidae foreleg (Hemiptera, Heteroptera).

Heteropteran legs are very diverse within and among taxa, and such variation is frequently correlated with life habits. Structural modifications are commonly present in the legs of the Pentatomoidea but are poorly studied. Using scanning electron microscopy, the tibia and pretarsal microstructure of 82 species of Pentatomidae (Heteroptera), three species of Scutelleridae, and ten species of Thyreocoridae were described, focusing on the pretarsal structure, the foretibial apparatus, and the foretibial comb.
