1. Stenodema longicuneata (Carvalho and Rosas, 1966) (Hemiptera, Heteroptera, Miridae) in Patagonia: redescription, new synonym and geographic distribution
Abstract: The genus Stenodema Laporte, 1832 is a group of grass-feeding plant bugs worldwide distributed, with five species recorded for the Subantarctic sub-region (sunsuMorrone 2015). Males of Stenodema longicuneata (Carvalho and Rosas, 1966) are redescribed and photographed. Stenodema laolaoensis (Carvalho, 1985) is proposed as a junior synonym of S. long

2. A new species of Oiovelia from Colombia, with notes for other three species of South American Veliinae (Heteroptera: Gerromorpha: Veliidae)
Abstract The new species Oiovelia shepardi is described based on macropterous specimens from the departments of La Guajira and Antioquia in northwestern Colombia, and is compared to its presumed closest relative. The female of Paravelia cunhai Rodrigues & Moreira, 2016 and the male of P.polhemusi Rodrigues, Moreira, Nieser, Chen & Melo, 2014 are described fo

3. First detection of the cosmopolitan invader Leptoglossus occidentalis Heidemann (Heteroptera: Coreidae) in Argentina
Abstract: Leptoglossus occidentalis Heidemann is a conifer seed bug, native to North America. This species is considered invasive and has reached several countries in the Northern Hemisphere and most recently Chile in South America. This work reports the first detection of this species in Argentina, with specimens from the Rio Negro province, in 2017. Ecolog

4. Plant Bugs Predators (Hemiptera: Heteroptera: Miridae) with References to Arthropods and Fungi in Brazil
Abstract: The present study demonstrates 30 plant bugs species associated with 50 records of prey and six records of mycophagy for Brazil. The data were compiled from Schuh’s Catalog, the literature, specimens deposited in entomology museums and exemplars from different regions of Brazil sent for identification. Some of the data from the literature used di

5. Eating with the enemy? Mimic complex between a stingless bee and assassin bugs
Abstract In this study, we record for the first time the genus Notocyrtus (Heteroptera, Reduviidae) from Argentina based on three species: Notocyrtus dorsalis (Gray), Notocyrtus dispersus Carvalho & Costa, and Notocyrtus foveatus Stål. We also describe and illustrate a mimetic complex comprising the three Notocyrtus species and Tetragona clavipes (Fabricius

6. Identificaton of the Alarm and Sex Pheromones of the Leaf-Footed Bug, Leptoglossus zonatus (Heteroptera: Coreidae)
The leaf-footed bug, Leptoglossus zonatus (Heteroptera: Coreidae), is mainly found in maize fields in Brazil. In this work, we elucidated and quantified the volatile compounds from nymphs and adults of L. zonatus. The defensive compounds produced by nymphs are aldehydes and oxo-alkenals, with some compounds showing different proportions between instars. For

7. Quantitative impacts of different planting arrangements on the populations of natural enemies in soybean
ABSTRACT. Natural biological control is an important alternative for the control of insect pests using natural enemies that occur naturally in agroecosystems. The potential of these insects can increase when they are adequately managed. Thus, the objective of this study was to quantify the populations of natural enemies in soybean cultivars with different gr

8. Belostomatidae (Heteroptera: Nepomorpha) held in the Invertebrate Collection of the Instituto Nacional de Pesquisas da Amazônia, Manaus, Brazil: inventory and new distributional records
Abstract Belostomatidae is a family of giant water bugs with 52 valid species in Brazil. Here, we list 33 valid species housed in the Invertebrates Collection of the Instituto Nacional de Pesquisas da Amazônia - INPA, Manaus, Brazil. Of the total species examined, 26 had their distributional ranges increased (new records provided in parentheses): Belostoma

9. Revision of Lineostethus (Heteroptera: Pentatomidae: Discocephalini)
ABSTRACT Lineostethus Ruckes, 1966 has four species, L. clypeatus (Stål, 1862), L. graziae Hildebrand & Becker, 1982, L. marginellus (Stål, 1872), and L. tenebricornis (Ruckes, 1957); mostly restricted to Central America, but with distribution records in the southern North America. Lineostethus is one of the discocephaline genera with discoid head. The las

11. Atividade da enzima ATPase dependente de MG 2+ em glândulas salivares de triatomíneos (Heteroptera, Triatominae)
RESUMO A atividade da enzima ATPase dependente de Mg2+ foi detectada nas três glândulas salivares de triatomíneos adultos, machos e fêmeas, de Triatoma infestans (Klug, 1834) e Panstrongylus megistus (Burmeister, 1835) (Heteroptera, Triatominae). Observou-se um predomínio de células binucleadas em D1 e D2, e mononucleadas em D3, com núcleos volumosos

12. Volatile Compounds from the Bark Bugs Phloea subquadrata and Phloeophana longirostris (Heteroptera: Phloeidae)
Phloea subquadrata and Phloeophana longirostris are subsocial species that differ from each other in their host plants and degrees of aggregation. Until recently, only ten low-molecular weight compounds, a sesquiterpene, and dimers of (E)-4-oxo-2-hexenal had been reported from the contents of P. subquadrata glands. Here, the main goal was to distinguish the
