Erlacda argentinensis, a new species of Rhyparochromidae (Heteroptera, Lygaeoidea) is described from Argentina. New locality records of E. arhaphaeoides Signoret 1863 are given.

The Big-Eyed Bugs, Chinch Bugs, and Seed Bugs (Lygaeoidea)

The Lygaeoidea, representing the second largest superfamily in the infraorder Pentatomomorpha, are one of the most diverse groups of Heteroptera with about 700 genera and more than 4,200 species in the world. In the Neotropics, about 184 genera and 836 species are included in 12 of the world’s 16 families. For each family, we provide a diagnosis; an overview of the classification; information on the general life history, ecology, and economic importance; and comprehensive keys to subfamilies, tribes, and genera for the Neotropical Region, including Mexico, Central and South America, and the West Indies.

Geographical distribution modelling of the bronze bug: a worldwide invasion.

The present study investigated the environmental variables that define a suitable climate for the bronze bug, Thaumastocoris peregrinus Carpintero & Dellapé, using presence‐only data, with the aim of identifying areas that have a suitable climate (and thus high probability) for future colonization and generating a spatially explicit predictive map of environmental suitability. An occurrence database (293 records) was compiled mainly from the literature. The environmental data were obtained from the WorldClim 1.3 dataset, and the models were performed using maxent, version 3.3.3k. Model performance was evaluated through cross‐validation. We used the null models approach to test our models. For model calibration, two datasets were defined (a non conservative dataset and a conservative one) by comparing the bioclimatic variables between native and introduced range using boxplots. According to both models, the range for T. peregrinus will continue to expand. In South America and Africa, the distribution of the bronze bug may expand mainly to the north‐east and central areas. Special attention should be given to the regions of southern U.S.A., Central America, and southern China and nearby countries, where conditions are highly suitable but the bronze bug has not yet been recorded and could only arrive by human means. Because Eucalyptus species, many of which are highly susceptible to infestation by the bronze bug, are increasingly being planted around the world, and because the bronze bug has spread so rapidly over the past 8 years, the bronze bug may be expected to appear in many areas where it has not yet been recorded.

Survey of the Heteroptera (Insecta: Hemiptera) of the Tandil hills, Buenos Aires province, Argentina. A list of Heteroptera (Hemiptera: Heteroptera) species from Tandil hills (Buenos Aires, Argentina) is presented. The list gathers bibliographical information as well as material collected by the authors. A number of 134 species are included, distributed in 31 families. Esuris terginus Stal (Rhyparochromidae) constitutes the first record of the genus and the species from Argentina.

Acrolophyses, a new seed bug genus and two new species (Hemiptera; Heteroptera: Rhyparochromidae: Myodochini) from forest-canopy fogging in Ecuador and Peru.

Th e new myodochine (Rhyparochromidae) genus Acrolophyses is described to accommodate the two new species A. arboricolous from Ecuador and Peru, designated as the type species, and A. hadros from Ecuador. Th e new species are diagnosed and described, and adult photographs, scanning electron photomicrographs of selected structures and illustrations of male genitalia are provided to aid in identifi cation. Th e relationship of Acrolophyes with the genera Distingphyses and Pephysena is discussed.

Williamsocoris, a New Genus of Schizopteridae (Heteroptera) from Argentina

Abstract A new genus and species, Williamsocoris ornatus (Schizopteridae: Hypselosomatinae), is described from Argentina. This is the first record of the subfamily in South America. The particular structures of the rostrum of this new taxon are unique in the family.

Description of Some Immature Stages of Largus rufipennis Laporte (Heteroptera: Largidae)

Instars II-V of Largus rufipennis Laporte (Heteroptera: Largidae) are described and illustrated, based on specimens from Corrientes, Argentina.

On the identity of Gargaphia subpilosa Berg, 1879, G. bergi Monte, 1940 and G. penningtoni Drake, 1928 (Insecta, Hemiptera, Heteroptera, Tingidae), with the description of immatures of G. bergi

Montemayor S. I. & Dellapé P. M. 2010. — On the identity of Gargaphia subpilosa Berg, 1879, G. bergi Monte, 1940 and G. penningtoni Drake, 1928 (Insecta, Hemiptera, Heteroptera, Tingidae), with the description of immatures of G. bergi. Zoosystema 32 (1): 155-162. ABSTRACT The correct designation of the lectotype of Gargaphia subpilosa Berg, 1879 is discussed and a paralectotype is recovered; G. penningtoni Drake, 1928 is considered a junior synonym of G. subpilosa Berg, 1879; G. bergi Monte, 1940 is raised from synonymy with G. subpilosa and instars II–IV are described. Illustrations of habitus of both species and of the immature stages II to V of G. bergi are provided together with photographs in the field of this last species.

Terrestrial Heteroptera (Hemiptera) from Moconá Provincial Park (Misiones, Argentina)

Mocona Provincial Park was created to protect the Paranaense forest including the Mocona Falls Natural National Monument. Knowledge of the insect fauna in the park is scarce and the Heteroptera have never been studied. In this work, 134 species from 17 families of Heteroptera collected in Mocona Provincial Park and surrounding areas included in the Yaboti Biosphere Reserve, are listed. The reduviids Arilus gallus (Stal, 1872), Repipta taurus (Fabricius, 1803), and Zelus nugax Stal, 1862; the tingids Leptodictya (Hanuala) paspalii Drake & Hambleton, 1934, and Leptopharsa vittipennis (Stal, 1873); the coreids Camptischium niger (Stal, 1870), Leptoglossus ingens (Mayr, 1865), Chariesterus cuspidatus Distant, 1892 and Cebrenis supina Brailovsky, 1995; the pentatomids Alveostethus pseudopolitus (Ruckes, 1957) and Dryptocephala integra Walker, 1867; and the blissid Xenoblissus lutzi Barber, 1954 are first records from Argentina.

Predicting the potential invasion suitability of regions to cassava lacebug pests (Heteroptera: Tingidae: Vatiga spp.).

Cassava (Manihot esculenta Crantz) is one of the most important staple crops for small farmers in the tropics, feeding about 800 million people worldwide. It is currently cultivated in South and Central America, Africa and Asia. The genus Vatiga is widespread throughout the Neotropical region. Its species are sympatric and feed exclusively on cassava. The main objectives of this paper are: (1) to assess the potential distribution of Vatiga, one of the most relevant pests of cassava; (2) to project the resulting models onto the world; (3) to recognize areas with suitable and optimal climates (and thus, high probability) for future colonization, and (4) to compare this model with the harvested area of cassava analyzing the climatic variables required by both the host and the pest species. Species distribution models were built using Maxent (v3.3.3k) with bioclimatic variables from the WorldClim database in 2.5 arc min resolution across the globe. Our model shows that Vatiga has the potential to expand its current distribution into other suitable areas, and could invade other regions where cassava is already cultivated, e.g., Central Africa and Asia. Considering the results and the high host specificity of Vatiga, its recent appearance in Réunion Island (Africa) poses a serious threat, as nearby areas are potentially suitable for invasion and could serve as dispersal routes enabling Vatiga to reach the continent. The present work may help prevention or early detection of Vatiga spp. in areas where cassava is grown.
