A complete checklist with new records and geographical distribution of the rove beetles (Coleoptera, Staphylinidae) of Brazil

This paper presents the first comprehensive list of 2,688 species of Staphylinidae (Coleoptera) recorded from Brazil. The list is based on the taxonomic and ecological literature, and new records from some insect collections, and includes locality references for each species. In addition, Brazilian localities and the country-level distribution outside of Brazil are provided for each species. Brazilian localities are organized by state, and include the bibliographic reference and page number where each locality was reported. All localities are geo-referenced, organized by state, and listed in an Appendix.Este trabalho apresenta a primeira lista completa das 2.688 espécies de Staphylinidae (Coleoptera) registradas para o Brasil. A lista inclui todas as localidades citadas para cada espécie e baseia-se na literatura taxonômica e ecológica disponíveis. Cada localidade inclui a referência bibliográfica e o número da página onde foram citadas. Também são apresentados registros inéditos obtidos de algumas coleções de insetos. Além das localidades brasileiras são citados todos os países com ocorrência conhecida para cada espécie. As localidades brasileiras, listadas no Apêndice, estão organizadas por estado e georreferenciadas

Redescription of Hypoptopoma inexspectata (Holmberg, 1883), with notes on its anatomy (Siluriformes: Loricariidae).

Hypoptopoma inexspectata is diagnosed and redescribed based on the examination of additional material and comparison with its congeners. This poorly known hypoptopomine species is distributed in the Paraguay and Paraná river draínages. Hypoptopoma inexspectata is diagnosable based on the autapomorphy biserial arrangement of anterior snout rostral margin odontodes, laterally extended to limit between second and third infraorbital plates, with dorsally directed dorsad series separated from ventrally directed ventrad series by a narrow odontode-free area, which at the level of first and second infraorbital plates is reduced to a dividing line of the series. The species can be further distinguished by the combination (1) low number of canal-bearing lateral plates (20-22, typically 21), (2) presence of a shield of prepectoral dermal plates, (3) arrangement of abdominal plates in one paired series of 3-5 plates, (4) shorter least interorbital distance 4856% head lengh, (5) larger horizontal eye diameter 17-20% head lengh, and (6) least orbit-nare distance 812% head lengh. Intraspecific variation skull dermal bones, neuracranium and suspensorium bones, dermal plates, adipose fin is reported. (PDF has 20 pages.

Conspectus genericus scorpionorum 1758–2006 (Arachnida: Scorpiones)

Genus-group names introduced for all extant scorpions in 1758–2006, are listed. The treatment follows the Conspectus of Francke (1985), with considerable additional information accumulated during intensive scorpio-logical research of 1983–2006. We list, as currently valid, 191 genus-group names, which include 167 genera and 24 non-nominotypic subgenera. The list also includes all available genus-group synonyms as well as unavailable names and detected incorrect spellings

Under the Empire of Spontaneous Solidarity: State and Political Action in the Theoretical Durkheimian Project (1892-1893)

This paper aims at identifying and examining all the principles arisen from the issues of the state and politics in Durkheim’s production during the period 1892-1893, signaled by the publication of his famous thesis on the cohesive role of the division of social labor. According to the in-depth analysis carried out in this article, the most important points of Durheim’s politics are four. Firstly, the conception of the state as an organ that translates an automatic social solidarity because it is an entire entity preexisting any political relationships. Secondly, the distinction of despotism as a regime that implies the complete absorption of individuals by the political apparatus. Thirdly, the problem of the growing enlargement of the state interventions in the individuals’ private life sphere. Finally, the incapacity of any political action to transform the society’s morphology.Fil: Inda, Graciela. Consejo Nacional de Investigaciones Científicas y Técnicas.

Un listado de la familia Bembicidae (Hymenoptera: Apoidea) de Túnez

A checklist of family Bembicidae from Tunisia is compiled based on data available in the literature, new material collected from different localities in Tunisia between 2017 and 2019, and some specimens hosted in the Muséum National d’Histoire Naturelle, Paris, France. As a result, 49 species and two subspecies in 16 genera of the family Bembicidae are recorded. Two genera: Psammaecius Lepeletier de Saint Fargeau, 1832, and Brachystegus A. Costa, 1859, are reported in this study for the first time. This is in addition to nine species and subspecies: Alysson ratzeburgi Dahlbom, 1843, Psammaecius eremorum de Beaumont, 1952, Stizoides klugii (F. Smith, 1856), Stizus fuscatus Morice, 1897, Stizus niloticus saharae Roth, 1934, Stizus pubescens arenarum Handlirsch, 1892, Stizus ruficornis strigatus Mochi, 1939, Stizus vespoides (Walker, 1871) and Brachystegus braueri (Handlirsch, 1887) that are new for the Tunisian fauna. New localities are also reported for several species and subspecies that had already been reported from Tunisia. Identified taxa are illustrated by digital photographs and their global and Tunisian distribution is presented.Se recopila una lista de la familia Bembicidae en Túnez basada en los datos disponibles en la literatura, en nuevo material recolectado de diferentes localidades de Túnez entre 2017 y 2019, y algunos especímenes conservados en el Muséum National d’Histoire Naturelle, París, Francia. Como resultado, se registraron 49 especies y dos subespecies en 16 géneros de la familia Bembicidae. Dos géneros: Psammaecius Lepeletier de Saint Fargeau, 1832 y Brachystegus A. Costa, 1859 se reportan en este estudio por primera vez. Esto se suma a nueve especies y subespecies: Alysson ratzeburgi Dahlbom, 1843, Psammaecius eremorum de Beaumont, 1952, Stizoides klugii (F. Smith, 1856), Stizus fuscatus Morice, 1897, Stizus niloticus saharae Roth, 1934, Stizus pubescens arenarum Handlirsch, 1892, Stizus ruficornis strigatus Mochi, 1939, Stizus vespoides (Walker, 1871) y Brachystegus braueri (Handlirsch, 1887) que son nuevas para la fauna tunecina. También se han encontrado nuevas localidades para varis especies y subespecies, que ya habían sido reportadadas de Túnez. Los taxones identificados se ilustran mediante fotografías digitales y se presenta su distribución global y en Túnez
