Discutimos también su presencia en Argentina [en base a previos errores de identificación bajo el nombre de Alloeorhynchus moritzii (Stein 1860)] y su probable presencia en Bolivia (basada en fotos de ejemplares vivos). Como parte del proceso para entender la distribución de esta chinche, recurrimos al análisis de imágenes satelitales de la localidad de colecta, ubicada en los límites del Monumento Natural Cerro Chovoreca, a través de una plataforma de mapas online de amplio uso, lo que nos llevó a detectar diferencias temporales extremas entre el estado de conservación real del sitio (en progresiva antropización durante la última década) y cómo éste se ve reflejado en las imágenes mostradas por defecto en la plataforma (el ecosistema intocado de hace más de diez años), además de otras señales de aparente ocultación de datos. Estas discrepancias son preocupantes, pues las imágenes en dichas plataformas afectan la percepción del público y de los tomadores de decisiones respecto al estado de conservación en las áreas silvestres protegidas.

Exploratory surveys were conducted in Argentina, Brazil, and Paraguay to discover natural enemies as possible biological control agents. One of the insects collected was subsequently identified as the stem boring weevil Apocnemidophorus pipitzi (Faust). The weevil was found at several localities in Paraguay in April 2007 and transported to Florida, USA, for biological and host range studies. Laboratory no- choice, and multiple-choice tests were performed to determine if A. pipitzi was suitably host specific for release as a biological control agent of Brazilian peppertree in Florida. In total, 79 North American plant species in 40 families and 28 Orders were tested. In the no-choice tests, complete development was significantly higher on Brazilian peppertree, Hardee peppertree, Schinus polygama (Cav.) Cabrera & I.M. Johnst., the invasive ornamental Chinese pistache, Pistacia chinensis Bunge and cultivated pistachio nut, Pistacia vera L. Both Pistacia spp. are chemically related to Brazilian peppertree. However, when given a choice, the stem boring weevil A. pipitzi reproduced only on Brazilian peppertree and the invasive congeneric Hardee peppertree. Overall, results of laboratory host range testing showed the stem boring weevil A. pipitzi is a Schinus specialist. This finding is consistent with field observations, museum records, and the preference-performance hypothesis, where larval survival, growth and normal development are maximised on plants selected for oviposition by the females.

Caught in the midst of personal and political conflicts, he still amazed to propose 593 new names in Hymenoptera (from sawflies to bees), Diptera (black flies, Simuliidae) and Lepidoptera (tiger moths, Arctiidae) between 1901 and 1922. Many of his primary types (syntypes and holotypes) were originally in his private collection, which were partially destroyed, and the remaining part scattered among multiple institutions. Other type specimens were exchanged before the destruction of his main collection to institutions in South America, USA, and Europe. The present catalog provides a complete list of the taxa proposed by Schrottky, including a bibliography of his 86 entomological publications. The catalog also lists all valid names proposed by Schrottky with details on the nomenclature, sex, type locality, and type repository for 126 known surviving types, representing 23% of all species-group taxa proposed by Schrottky. The remaining types (77%) are most likely lost. A brief biography is followed by a discussion of where to locate and how to treat original types and neotypes of Schrottky.

In accordance, this paper presents an altitudinal survey of wasps (Hymenoptera, Aculeata, Vespidae) in Itatiaia National Park, Brazil, which is a protected area covered by Atlantic Forest in a mountainous landscape, with altitudes ranging between 540 and 2791 metres above sea level. Six altitudinal zones were sampled with entomological net, and the abundance and diversity of the species were indicated by zones. Field sampling took 288 h of discontinuous activity, which was randomly conducted from December 2012 to December 2013. A total of 398 individuals belonging to 29 species and two subfamilies (Eumeninae and Polistinae) were sampled. Eight species are new records for the state of Rio de Janeiro. We found a monotonic decrease in wasp diversity in relation to altitude, and the number of captured individuals differed significantly between the low and high altitudes.

Previously to this study, the fauna of soldier flies in the country comprised 18 genera and 29 species, which has been raised up to 35 genera and 63 species, of which only nine are assigned to morphospecies level. The list of species is based on the examination of the original descriptions of all nominal species, all other references known to us containing taxonomic and distributional information, and new material examined from various collections. Images of 45 species are herein provided, which include type specimen images of seven valid species, of which three are exclusively found in the country. One subfamily is newly reported from Paraguay: Chrysochlorininae. Fourteen genera are newly reported from Paraguay: Acanthinomyia Hunter, 1900; Archistratiomys Enderlein, 1913; Auloceromyia Lindner, 1969; Chrysochlorina J...

Due to a mixture of plasticity in building behavior and flexibility in substrate preferences during nest building, the group has been reported nesting in a variety of places, including decaying nests abandoned by termite species. Yet, evidence of wasps nesting inside senescent termite mounds is poorly reported, and to date, accounts confirming their presence inside active colonies of termites are absent. Here, we address a novel intriguing association between two species from the Brazilian Cerrado: a previously unknown potter wasp (nest invader) and a termite species (nest builder). Besides scientifically describing Montezumia termitophila sp. nov. (Vespidae: Eumeninae), named after its association with the termite Constrictotermes cyphergaster (Silvestri, 1901) (Termitidae: Nasutitermitinae), we provide preliminary ...

Before this finding, in the decade of the 1940's, this species of fly was wrongly recorded from Paraguay, based on material collected in Bolivia, some 300 km from the border to Paraguay.

Hay pocos antecedentes de estudios sobre la biogeografía del Paraguay, pero dos de ellos influenciaron en la identificación de áreas biogeográficas del Paraguay: Así las ecorregiones de la Región Oriental de Acevedo et al. (1990) y las regiones ornitogeográficas de Hayes (1995) muestran que estuvieron inspiradas en la definición de las regiones forestales de Tortorelli (1967). Así mismo, la propuesta de Dinerstein et al. (1995) influenció en las propuestas desarrolladas por Clay et al. (2005), Cacciali (2010) y Avila (2018).

Several reports of introduced species of this genus in the Americas have been recorded since early in the twentieth century, with a present list of six species recorded to date from the Americas and the US territory of Hawaii. In this paper we give new geographical records for the African-native species Eumerus obliquus (Fabricius, 1805), which reflect the expansion of this fly through Brazil and Paraguay along the last twenty years. At the same time, we report a second species from Paraguay, Eumerus aurifrons (Wiedemann, 1824), being this the first Western Hemisphere record for this Asian-native species. We finally provide an identification key to all of the species of Eumerus presently known from the Americas and Hawaii.

It eventually escaped cultivation and is a serious threat to the state’s biodiversity. In the 1980s, this invasive weed was targeted for classical biocontrol. Surveys for natural enemies of Brazilian peppertree conducted in the native range resulted in the discovery of several candidate biocontrol agents. A stem-boring weevil identified as Apocnemidophorus pipitzi (Faust) was collected in Paraguay and transported under permit to Florida, USA. A laboratory colony of A. pipitzi was established in April 2007 by caging adults on cut branches of Brazilian peppertree supplemented with leaf bouquets. Adults are defoliators that feed mainly on the upper surface of subterminal leaflets. Females deposit eggs singly inside the stems and larvae feed under the bark where they damage the vascular cambium. There are five instars, pupation occurs inside the stem and a new generation is produced in 3–4 months. Growth of potted plants with and without exposure to weevil herbivory was compared over an 11-month period. Feeding damage by adults and larvae significantly increased leaf abscission and reduced leaf and root biomass accumulation.
