The first step to understanding the species present in a particular area is to perform inventory and assemblage studies. To obtain a species inventory, it is important to determine parameters such as species richness and relative abundance. This information can be useful for future studies and decision-making purposes in the conservation area. Desp...

Insect studies for different regions are scarce as most of the material is collected in isolation, thus preventing extensive taxonomic listings. Conducting inventories of terrestrial biodiversity in a specific area is an arduous task, with many obstacles: mainly the lack of data on taxonomic and geographical distribution necessary to study them. Th...

The orsillid genus Nysius Dallas is a complex and large genus with more than 100 described species worldwide, and includes many species of agricultural importance, one such example is N. simulans (Stål) from Argentina. Three species of Nysius are found in this country: N. simulans (Stål), N. irroratus (Spinola) and N. puberulus Berg. The material a...

Eight genera and 21 species of the tribe Anisoscelini (Coreidae, Coreinae) are recorded in Argentina: Anisoscelis foliaceus (Fabricius); Coribergia declivicollis (Berg); Dalmatomammurius vandoesburgi (Brailovsky); Holymenia hystrio (Fabr-icius); Leptoglossus chilensis (Spinola); L. cinctus (Herrich-Schaeffer); L. concolor Walker; L. crassicornis (D...

At the global level are 18 genera that constitute Rhopalidae family in our country are only 5 genera, of which 3 are provided in this contribution to the province of La Pampa. The material comes from the entomological collection of the Museum of La Plata (Argentina) and campaigns conducted by the authors in the province of La Pampa.

In this work, the present ostracofauna in the "Laguna Don Tomás" (36 º 18 ' 18.31 " S and 64 º 18 ' 49.02” W), located in the city of Santa Rosa, La Pampa, Argentina, is studied. Seasonal studies were carried out, 1447 valves and shells were recovered. Four species were identified and specimens of Heterocypris símilis with Oichnuns simplex were fou...

We report the first record of Phitacnemia picta capture (Drury, 1770) (Heteroptera: Coreidae) for the province of La Pampa. This species has economic importance attacking ornamental and fruit crops. This record brings the number of species of Heteroptera in the province.

Eight genera and 13 species of the tribe Acanthocerini are recorded in Argentina, i.e., Athaumastus haematicus (Stål), A. macer Brailovsky, A. subcarinatus (Stål), A. subterlineatus Bergroth, Beutelspacoris sanchezi Brailovsky, B. dilatata Casini, Camptischium clavipes (Fabricius), Crinocerus sanctus (Fabricius), Dersagrena flaviventris (Berg), D....

The world change in land use and crop modification has been, at the expenses of forests, pastures and swamps. Argentina pampean plains have not been an exception because of this global tendency with an agricultural border continuous advance from the east to the semiarid west. This generates a loss of biological diversity that affects a great number...

In this study a relay of the arthropods’ families was made in adjoining zones next to the wetland area known as ―Laguna Don Tomás‖ in Santa Rosa city, La Pampa, Argentina. Diversity and abundance of Arthropod families present in the area were analyzed; also measured was the variability in community composition during the different seasons of the ye...

The cosmopolitan genus Solenopsis (Hymenoptera: Formicidae) is a large ant genus with 108 species in the New World (Bolton, 1995), of which 21 are known as fire or red ants (hormigas coloradas). They are aggressive and armed with a defensive sting. Some species are important plagues, as they have undergone steep increases in their population densit...

La descripción de Solenopsis leptanilloides Santschi es incompleta hasta el presente, por ello en esta contribución se redescribe la obrera y se cita por primera vez para la provincia de La Pampa (Argentina). El material estudiado, compuesto por obreras, fue recolectado en el interior de los nidos de Acromyrmex striatus Roger en la periferia de la...
