Two new species of Euathlus (Verhandlungen der Kaiserlich‐Königlichen Zoologisch‐Botanischen Gesellschaft in Wien, 1875, 25, 125) from Argentina are described. Euathlus ameghinoi sp. n. and Euathlus ventus sp. n. are the first records for the Patagonian Steppe. Here we used mitochondrial DNA (cox1) to perform the first molecular phylogeny of some representatives of the genus. In addition, we present the first description of the sexual behaviour of the genus. Both molecular and cladistic morphological analysis showed the genus Euathlus as monophyletic, and new species were recovered as sister groups. New species show new morphological variations of typical characters for the genus (e.g. tibial apophyses and palpal organs). [ABSTRACT FROM AUTHOR]

En este artículo abordamos la conflictividad social en el Noreste de Chubut durante la última dictadura militar desde 1976 a 1982 para dar cuenta de cuales fueron los conflictos que se realizaron, que sujetos lo protagonizaron, quienes lo organizaron y de que forma el conflicto fue realizado, dentro de un análisis que incluye a lo que definimos como estructura socio-económica, comprendiendo a los conflictos como parte constitutivita de la sociedad. Partiendo del análisis del periódico Diario Jornada realizamos un estudio de tipo cualitativo y cuantitativo que nos permite construir ciclos y fases hacia dentro del período, permitiendo observar cómo se construyen las modificaciones dentro de la conflictividad dentro de los años signados por el devenir de la dictadura militar.

In a forest of Nothofagus pumilio (lenga) in northern Chubut, we found a stand affected by Notophorina sp. (Hemiptera, Psyllidae) with outstanding foliar symptoms. We assumed that it is about a peak of abundance, which is the first record in Argentinean Patagonia. Our aim was to characterize the stand and the health condition of affected trees related to the peak abundance of Notophorina sp. In a stand located at 42°41'36.06" S - 71°44'42.26" W, in the Parque Nacional Los Alerces (Chubut, Argentina), two samplings were carried out in an eighteen day period (T1, T2) during the summer (January and February) of 2020. A health survey was performed and Notophorina sp. abundance was evaluated. Thirty percent of the trees showed defoliation in T1 and this value increased to 50% in T2. The symptoms were chlorosis, necrosis, leaves curling and partial or total defoliation. At T2, the previously affected trees had smaller leaves (1.80±0.38 cm²) than those recently affected (3.79±0.38 cm²), while the leaves of the healthy trees were the largest (6.99±0.38 cm²). The specific leaf area was similar for trees with old and recent infestation (123.3±20.34 cm²/g vs. 159.27±20.34 cm²/g) and significantly higher in healthy trees (289.15±20.34 cm²/g). The population density decreased drastically between both samplings (87%). This study contributes to the bioecological background of Notophorina sp. in the Patagonian Andean region and assesses the effect on its hosts. [ABSTRACT FROM AUTHOR]

Over the centuries there have been a number of attempts, for economic, political and religious reasons, to create Welsh settlements overseas. The most successful of these, in terms of longevity at least, and perhaps the best known of all Welsh emigration ventures, was the establishment in 1865 of a Welsh Settlement in Patagonia, in what is now the Province of Chubut in Argentina, where perhaps as many as 5,000 of the inhabitants still speak Welsh fluently or have some ability with the language. The preservation of Welsh identity was central to the Patagonian project, which aimed to create a new Welsh-speaking, self-governing Wales overseas, founded on Christian and democratic principles. From the outset, songs played an important role in fostering the ideals that inspired the founders of the Settlement, ideals that would come progressively under threat as the Argentine government increasingly asserted its authority over the Settlement, promoting Argentinian identity and replacing Welsh with Spanish as the medium of education. This paper gives an overview of the development of the Welsh Settlement in Chubut down to the present day, focussing especially on the role of song in nurturing the dream of the Settlement’s founders.

En un bosque de lenga (Nothofagus pumilio) en el norte de Chubut, detectamos un rodal afectado por Notophorina sp. (Hemiptera, Psyllidae) con sintomatología foliar destacada. Asumimos que se trata de un pico poblacional de este succionador, por primera vez registrado en la Patagonia argentina. El objetivo de este trabajo fue caracterizar la situación sanitaria del rodal y de los árboles afectados, asociada con el pico poblacional de Notophorina sp. El estudio se llevó a cabo en un rodal situado a los 42°41’36.06’’ S - 71°44’42.26’’ O, dentro de la jurisdicción del Parque Nacional Los Alerces (Chubut, Argentina). Se efectuaron dos muestreos en el verano de 2020 (enero-febrero), en un período de dieciocho días (T1, T2); se realizó una prospección sanitaria y se cuantificó la abundancia de Notophorina sp. sobre las ramas de los árboles afectados. El 30% de los árboles presentó defoliación en T1, y este valor subió a 50% en T2. Los síntomas registrados consistieron en clorosis, necrosis, arrepollamiento de la lámina foliar y defoliación parcial o total. Al momento del segundo monitoreo, los árboles con infestación más antigua presentaron hojas de menor tamaño (1.80±0.38 cm2) que los infestados recientemente (3.79±0.38 cm2), mientras que las hojas de los árboles sanos fueron mucho más grandes (6.99±0.38 cm2). El área foliar específica fue similar entre árboles con infestación antigua y reciente (123.3±20.34 cm2/g vs. 159.27±20.34 cm2/g), pero significativamente menor que en los árboles sanos (289.15±20.34 cm2/g). La densidad poblacional del succionador descendió drásticamente entre ambos muestreos (87%). Este trabajo contribuye a generar antecedentes bioecológicos sobre Notophorina sp. en la región de los Andes patagónicos, y a dimensionar el efecto sobre sus hospederos.

A 209 m-thick sedimentary succession exposed at Estancia Redonda Chica locality (northeastern Patagonia, Argentina) includes both the Gaiman Formation (Early Miocene) and the Puerto Madryn Formation (Late Miocene). Based on the sedimentologic analysis, the Gaiman Formation is interpreted as accumulated in a marine inner shelf to shoreline environment, whereas an estuarine to terrestrial environment is interpreted for the Puerto Madryn Formation. Fifteen samples were processed and analyzed for diatoms, providing for the first time a micropaleontological record for these units, allowing us to go deeper into the paleoenvironmental interpretations. Fourteen diatom species, two diatom genera, and chrysophyte stomatocysts were identified. The dominant diatom elements among the samples are Paralia sulcata, Lemnicola hungarica, Cocconeis placentula, and Pseudopodosira sp., together with chrysophyte stomatocysts. Paleoecological information drawn from diatom assemblages is consistent with paleoenvironmental interpretations based on sedimentological analysis for both units. However, diatom analysis for the Gaiman Formation suggests a strong freshwater influence in an inner shelf environment, which went unnoticed by utilizing other proxies. We suggest a high-productivity marine zone may have developed as a consequence of nutrient supply from rivers favoring diatom growth. This could explain the unique great abundance of macroinvertebrates and marine vertebrates preserved in the sedimentary succession. [ABSTRACT FROM AUTHOR]

Clams belonging to the genus Corbicula are considered one of the most harmful freshwater invaders with strong economic and ecological impacts. In South America, they were first detected in 1979 in the Río de La Plata estuary and since then they have rapidly spread throughout the north of Argentina. To the south, the Corbicula clam began appearing in the Colorado (~ 38°S) and Negro River (~ 40°S) basins around 1997–1999, and in the Limay and Neuquén Rivers (~ 38°S) around 2005. Almost twenty years later, this invasive clam reached the Chubut River (Chubut Province, Argentina). Here, we report for the first time the presence of Corbicula in the Chubut River (43.29° S), which represents the southernmost record of this invasive bivalve in the world. The most likely introduction pathway for the Corbicula clam in the Chubut River is ballast water associated with an estuarine port. Special attention is now required to detect the range of the invasion along the Chubut River basin and adjacent river basins such as Chico River to evaluate the ecological effects and the potential economic impacts on the industry.

This case study analyzes processes of contentious action in rejection of so-called “mega-mining” deployed on a subnational scale in Argentina from 2019-2021. These processes respond to a new stage in the cycle of social conflict over environmental issues in twenty-first century Argentina. This stage is configured through citizen resistance in different provinces with repertoires of convergent struggle, particularly against state mining policy. This renewed policy promoted by the national government in coordination with provincial governments and transnational corporations takes place in a context of socio-economic, environmental and health crises exacerbated by the outbreak of the COVID-19 pandemic. Based on a technocratic vision of society-nature articulations that clash with aspects of the current environmental legal system in Argentina, this model generates multiterritorial tensions (political, social, and cultural) in diverse subnational areas. The objective of the article is to understand the transformations of the actor dynamics around state mining policy in this context, including diverse and complex civil-social and political-institutional strategies.

The early diversification of caimanines is one of the least understood aspects of the evolutionary history of Crocodylia. The Palaeogene Argentinian caimanine record is extremely relevant because it provides key information on the early history of the clade. Most of the Palaeocene South American species are only or mainly known from partial lower jaws. Among the oldest Argentinian caimanines, Notocaiman stromeri (middle Palaeocene, Las Violetas Formation, Chubut Province) and Eocaiman palaeocenicus (lower Palaeocene, Salamanca Formation, Chubut Province) are represented by a partial left dentary and a fairly complete lower jaw, respectively. Notocaiman stromeri, has been phylogenetically interpreted from an alligatorid closely related to Eocaiman to an indeterminate eusuchian, but a modern anatomical revision of this species is lacking. Here, we redescribe in detail the only known specimen of Notocaiman stromeri (PVL 752) to revise its taxonomy and phylogenetic relationships. We concluded that Notocaiman and Notocaiman stromeri are nomina dubia and we refer PVL 752 to Eocaiman cf. E. palaeocenicus. Our phylogenetic analysis found Eocaiman palaeocenicus as the sister taxon to the Eocaiman cavernensis + Eocaiman itaboraiensis clade. Thus, here we reduce the alpha taxonomic diversity of alligatorids in the Palaeogene of South America but reinforce a geographically broad diversification of the genus Eocaiman, from the Palaeocene to the Eocene/Miocene in this continent.

En este artículo se analizan las relaciones entre los inmigrantes sirio-libaneses y los principales mediadores de sus experiencias migratorias en el sur de Río Negro y en el norte de Chubut, durante la primera mitad del siglo XX. Se argumenta que los intermediarios más importantes fueron los connacionales árabes, aunque hubo actores indígenas, criollos y de otras nacionalidades que ejercieron mediaciones claves. Se identifica a los principales intermediarios en las trayectorias de los inmigrantes árabes, al mismo tiempo que se reconstruyen parcialmente sus redes de negocios y su alta movilidad. Se combina la metodología clásica de la crítica textual de fuentes primarias con el uso de herramientas de Sistemas de Información Geográfica y Análisis de Redes Sociales. Se concluye que las redes de negocios de los inmigrantes árabes estuvieron fuertemente cohesionadas al interior del grupo de connacionales, articulando territorialidades mercantiles amplias y conectando diferentes regiones. Si bien los árabes podían aparecer como un grupo migratorio disgregado, pudieron consolidar redes sociales que se mostraron eficaces y que favorecieron su acumulación económica.

Este artículo aporta al conocimiento de algunas formas de resistencia popular, y ciertos mecanismos de represión, durante la primera etapa del golpe de estado que derrocó al gobierno de Juan Domingo Perón en la provincia de Chubut. Los registros sobre el tema en Chubut son escasos, fragmentarios y están dispersos en diversos reservorios; muchos de ellos recién comienzan a estar abiertos para la consulta de los investigadores. Sin pretensión de cubrir la totalidad de las acciones desarrolladas en un territorio tan amplio como el del Chubut, se describen una serie de sucesos que evidencian cómo se plasmó esa resistencia popular multiforme, al tiempo que se imponía un aparato represivo que pretendía controlarlo todo. El acercamiento fue realizado a partir de diversas fuentes: el relevamiento sistemático del principal medio de prensa local (el diario Jornada), fuentes bibliográficas y un prontuario policial clave, caratulado como “Infracción Decreto Ley 4161, año 1956”

The genus Ctenomys includes a high number of taxa, with at least ten species from Patagonia and three recently described species for northeastern Chubut Province (Argentina). Ctenomys sociabilis is a social species of the genus Ctenomys and is currently distributed in the surrounding area of Sierra Cuyin Manzano (Neuquén Province), with a recently extinct population that occurred in Laguna Nahuelquir (Cushamen, Chubut Province). Molecular analyses have placed C. sociabilis at the base of Ctenomys clade, as the sister species to all other Ctenomys. Based on a morphological assessment (qualitative and quantitative) and DNA sequencing, we describe a new species of Ctenomys from Esquel, Chubut Province. Phylogenetic analysis shows the new species to be closely related to C. sociabilis, with evidence of solitary behavior. This new species is the first reported to be closely related phylogenetically to Ctenomys sociabilis at the base of the Ctenomys phylogeny. We provide anatomical comparisons between the new species and other species of Ctenomys from Patagonia, especially C. sociabilis. [ABSTRACT FROM AUTHOR]

Por más de tres décadas el Laboratorio de Paleontología de Vertebrados de la Universidad Nacional de la Patagonia San Juan Bosco ha trabajado de forma sistemática en afloramientos cretácicos del centro sur de Chubut y norte de Santa Cruz. Durante todo este tiempo contribuyó al conocimiento de la dinámica paleoecológica de la fauna de vertebrados, particularmente dinosaurios. El trabajo y el esfuerzo, no solo permitieron incrementar el conocimiento, sino también la interacción con colegas e instituciones nacionales y extranjeras y la formación de recursos humanos. Asimismo, el laboratorio por medio de nuevas líneas de investigación y proyectos continúa trabajando con el objetivo principal de contribuir al desarrollo de la Paleontología en general y la Paleoherpetología en particular de la Argentina.

La presente investigación propone analizar el surgimiento de controversias alrededor de la emergencia de los primeros conflictos socioambientales, que captaron la atención de la opinión pública en Argentina entre 1980 y 2003, tomando en consideración dos casos emblemáticos: Gastre y Esquel, ambos situados en la Patagonia argentina. Nos proponemos establecer un recorrido histórico-ambiental donde tenga preminencia una matriz teórico-metodológica integral constituida por: historia ambiental, estudios decoloniales y comunicación de riesgo. Como fuentes de análisis emplearemos diarios de tirada nacional como Clarín y La Nación.

Si bien Argentina cuenta con un gran potencial minero, la minería metalífera de gran escala se ha desarrollado con escaso conocimiento de su potencial económico y en paralelo a una conflictividad social. En la provincia del Chubut, el proyecto Navidad es el principal incentivo para modificar el marco legal provincial y permitir su avance. Este trabajo busca, mediante escenarios, dimensionar y contextualizar los potenciales beneficios económicos (exportaciones, ganancias, recaudación, empleo) que podría generar dicho proyecto, especialmente al Estado provincial. Los resultados en materia fiscal revelan que las contribuciones a la provincia serían limitadas, pues podrían representar el 1.9 % del presupuesto y un 7.5 % de los ingresos por regalías hidrocarburíferas. El mayor impacto local podría generarse por empleos en comunas cercanas al yacimiento, aunque es poco factible dado el perfil agropecuario de dicha población. El debate público y legislativo sobre la minería en Argentina requiere más evaluaciones de este tipo a fin de estar mejor informado.

We describe the history and characterize the unions that integrate the workers of the processing on land of the Argentine fishing industry. The Sindicato Obrero de la Industria del Pescado (SOIP) in the province of Buenos Aires, and the Sindicato de Trabajadores de la Industria de la Alimentación (STIA) in the Patagonia, represent these workers.We are interested in recognizing their specificities, their paths and the reasons that explain the regional fragmentation of the union representation of this working group. We focus the observation in the port city of Mar de Plata and in northeastern Chubut (core key fishing in Argentina). We work with interviews, bibliographic systematization and journalistic, officials, unions and business sources. It is evidenced that the territorial division creates difficulties to conquer their labor claims, at the same time that organizational transformations are highlighted in the work process (due to changes in the target species) and of the gender composition in some of the unions.

Se registró por primera vez el comportamiento de homing en Chaetophractus villosus. Se capturaron 33 individuos de C. villosus y se liberaron a diferentes distancias en Península Valdés, Chubut, Argentina. Del total de individuos, el 30 % regresó al punto captura dentro de los 12 días desde la liberación. El tiempo de recaptura aumentó de manera no linear respecto a la distancia, por lo que los puntos de liberación podrían estar fuera de su área de acción. El regreso al sitio de captura posiblemente se debe a que los peludos reconozcan a este sitio como fuente de recursos alimenticios.

The present range of the southern river otter Lontra provocax in Argentinean continental Patagonia represents only c. 20 % of its original distribution, with only one known population that is found in the southwestern area of the Río Limay basin (border between Neuquén and Río Negro provinces). Based on bibliography, we reconstruct the historic distribution of the species in Chubut, we compile information on its potential and confirmed presence and report a new sighting for the province. Finally, we analyze these sightings in relation to the original situation and its relevance for the restoration of the southern river otter populations of Chubut province. [ABSTRACT FROM AUTHOR]

Nuestro trabajo se sitúa en el campo de estudios sobre el pasado reciente en nuestro país y aporta, en ese sentido, a la construcción de un estado de la cuestión acerca de algunas de las principales perspectivas analíticas y discusiones dentro del mismo. Por un lado, buscamos reconstruir las principales líneas de interpretación acerca de las características generales del período que va de 1955 a 1976. En segundo lugar, reseñamos algunos de los principales estudios que analizan el proceso de activación social y politización del período señalado, y en particular, el de la vía de radicalización peronista. Y finalmente la ponencia, nos aproxima a aquella bibliografía centrada en estudios de casos locales dentro del espectro de la izquierda peronista que contribuyen de esta manera, a visibilizar otras expresiones de la militancia de la época, más allá de lo que ocurría en los principales centros urbanos. En cuanto a la región específica de Chubut y el período que venimos señalando daremos cuenta de algunos estudios que han avanzado en el conocimiento respecto del peronismo en la Patagonia y sus distintos ámbitos de anclaje y desarrollo.

The endemic Patagonian genus Titomaya gen. nov. is erected to include the Danian Meretrix chalcedonica (Lefipan and Salamanca formations) and Titomaya longobucca sp. nov. (Salamanca Formation) from the Chubut Province (Argentina). Although Meretrix and Titomaya share the same characteristic sculpture of their nymphs, Titomaya is differentiated by having medium to small, subtriangular, higher than long shells, a narrower and shorter hinge plate, smaller cardinal and anterior teeth, and by the development of a deeper pallial sinus. This new genus rules out the presence of Meretrix in Patagonia, as was long believed, and increases the list of endemic taxa that characterize the Danian assemblages of Patagonia.

Este trabajo presenta los resultados del análisis zooarqueológico del sitio Acevedo 1, ubicado en el ecotono bosque-estepa del centro-oeste de Chubut, un área poco conocida en términos de la subsistencia humana del pasado. A este respecto, las evidencias en el sitio son escasas. En los vertebrados grandes, una huella de corte y otra de percusión en dos huesos de mamífero indeterminado. Los daños de carnívoros (mascado y corrosión digestiva) muestran que la mayor parte del conjunto faunístico es resultado de la actividad de aves rapaces y principalmente zorros que utilizaron el alero.

Este artículo describe el Fondo de Prontuarios Policiales del Chubut (FPPC), contextualizando la producción de los documentos que lo componen, y caracterizando las tecnologías de identificación que se emplearon para clasificar la población y controlarla conforme a la legislación nacional y los tratados internacionales suscritos por la Argentina. Se destaca el valor del Fondo, considerando que los prontuarios ofrecen información de síntesis sobre miles de habitantes del Chubut con fechas extremas de documentación desde fines del siglo XIX. Finalmente, se argumenta que este repositorio presenta potencialidades para diferentes líneas de investigación, considerando la diversidad tipológica y sus magnitudes.

Notoungulates were the most diverse group of South American native ungulates during the Cenozoic. They ranged from small rodent-like to heavy rhino-like forms and, despite this morphological diversity, their monophyly is widely accepted. Within Notoungulata, Typotheria and Toxodontia (the two major clades) are well supported, whereas phylogenetic relationships between early diverging lineages (formerly grouped as 'Notioprogonia') are still a matter of debate. Within Toxodontia, 'Notohippidae' sensu Simpson (1967) is a paraphyletic group lacking systematic consensus and represented by small to medium-sized taxa from the late Eocene to early/middle Miocene, but that were especially diverse during the late Oligocene. In this context, we describe a new toxodont (Teushentherium camaronensis gen. et sp. nov.), found at Barrancas Blancas, an Oligocene locality in the south-east of Chubut (Patagonia, Argentina). It is represented by the anterior portion of the skull (palate and anterior snout) and the associated horizontal rami of the mandible. A phylogenetic analysis places the new taxon as closely related to taxa traditionally regarded as 'Notohippidae'. In addition, extensive taxonomic sampling allowed us to assess phylogenetic relationships among other representatives. As expected, only Homalodotheriidae, Leontiniidae and Toxodontidae were recovered as monophyletic groups, whereas neither 'Notohippidae' nor 'Isotemnidae' were supported. We also identified a clade (sister to Homalodotheriidae) for which we propose the name Eutoxodontia. It includes 'Notohippidae' sensu Simpson, Leontiniidae and Toxodontidae, and provides a more accurate definition for middle and later diverging toxodonts, avoiding terminology such as 'advanced' or 'derived'. We hope to contribute to the stabilization of toxodontian taxonomy, to highlight the main gaps in this respect, and to promote future contributions dealing with this intricate issue.

The species Carodnia feruglioi and 'Ctalecarodnia cabrerai' (Xenungulata) were originally described on scarce fragments of teeth from the current Peñas Coloradas Formation at Bajo Palangana (Chubut Province, Argentina). Based on them, the 'Carodnia horizon' was named containing one of the oldest native ungulates from South America. However, the type material of these enigmatic xenungulates has remained unknown for more than 80 years, and no updates were performed since their original descriptions. Here, the identification and re-study of the type material, as well as other unpublished specimens from several collections, allowed us to reconstruct part of the dentition of Carodnia feruglioi, describe previously-unknown teeth (e.g., incisors, lower canine, first and second lower molars, and upper molars) and introduce new dental characters for this species. Using length and width ratios of lower dentition (fourth lower premolar, second and third lower molars) as proxies, we compared the metric disparity among the Carodnia species. Based on this study, we provide an emended diagnosis for both the genus and species Carodnia feruglioi and establish comparisons among the six xenungulate documented. [ABSTRACT FROM AUTHOR]

En este trabajo se entrega un listado de 116 especies y subespecies de aves recolectadas y observadas en la Península Valdés y litoral marítimo de Chubut a Isla Quintano. Varias citas significan una ampliación de sus rangos conocidos. También se remiten datos sobre los hábitats y las nuevas zonas de reproducción. Los sitios principales se muestran en un mapa y algunas fotografías de aves documentan material taxidérmico.

Nos proponemos mostrar las formas en que, desde la formación del estado provincial en Chubut (1957), comenzó a establecerse una narración “oficial” del pasado, constituida por el propio gobierno, y a través de una intelectualidad provincial, organizada en la Junta de Estudios Históricos. Dicha narración del pasado chubutense cumplió un rol fundamental en la institucionalización del estado provincial, en tanto se centró en la acciones de grupos interpretados como “agentes civilizatorios”: los colonos galeses, los salesianos y las ocupaciones españolas del periodo colonial, negando así la agencia o la historia de los pueblos indígenas de Chubut.

El objetivo del presente trabajo es dar a conocer la Colección Bioantropológica Frengüelli-Brunet, constituida por Rodolfo F. J. Brunet (1926-1996), naturalista y aficionado a la arqueología de la ciudad de Puerto Madryn, que se integra por restos humanos procedentes principalmente de la provincia del Chubut. En la actualidad esta colección se encuentra bajo el amparo de la Ley Provincial XI Nº 11 sobre “Régimen de las Ruinas y Yacimientos Arqueológicos, Antropológicos y Paleontológicos”. La colección ingresó al repositorio Bioantropológico del IDEAUS–CONICET a solicitud de la Secretaría de Cultura del Chubut. Se realizó el proceso de curaduría y protección basado en las normas éticas vigentes. Se determinó información bioantropológica básica: cantidad de individuos, determinación del sexo y estimación de la edad. Se efectuó la revisión de documentación asociada a la colección, a partir de la cual se obtuvo información sobre los sitios de hallazgo Si bien esta colección se conforma a partir de la recuperación asistemática de los esqueletos, sin datos cronológicos y de contexto, la mayoría provienen de la costa central y la región centro oeste de Chubut, cuya información previa es escasa. En este sentido su puesta en valor permitirá sumar aportes sobre las poblaciones originarias de la región.

Although Argentina has great mining potential, large-scale metal mining has developed with little knowledge of its economic potential and parallel to social conflict. In the province of Chubut, the project known as Navidad acts as the main incentive to modify the provincial legal framework and allow its progress. Through different scenarios, the purpose of this work is to measure and contextualize the potential economic benefits (exports, profits, tax collection, employment) that this project could generate, especially for the provincial State. Taxation results reveal that contributions to the province would be limited, representing 1.9 % of the provincial budget and 7.5 % of revenues from hydrocarbon royalties. The greatest local impact could be generated by jobs in the communes near the site, something rather unlikely given the agricultural profile of the population there. The public and legislative debate on mining in Argentina requires more evaluations of this type in order to be better informed. [ABSTRACT FROM AUTHOR]

Aldea Beleiro is one of the three focus localities of research between 2018-2019, with the PICT "Strategies and community and state devices in territorial development processes of small towns and dispersed rural areas in the southwest of the province of Chubut." The objective is to analyze strategies and devices, both state and community, which, depending on the isolation and integration scenarios, contribute to processes of territorial development in small towns and dispersed rural spaces in the southwest of the province of Chubut. The methodology is approached from the research cartographic and articulates a series of developing and experimental tools. The research process puts in permanent dialogue the texts produced, the partial conclusions and the ideas produced with the local population to think about the different strategies and devices implemented from the community, thus activating micro-processes of territorial development.

En el presente artículo argumentamos que la promesa de plenitud que sostiene la reproducción de la vida comunitaria chubutense, pasa también por la pretensión utópica de administrar el tiempo y el espacio de forma tal que cada sujeto (o territorio) ocupe el lugar que le corresponde según su capacidad. Esto hace a una distribución de lugares sociales marcada por el tiempo del trabajo monoproductivo del petróleo y la necesidad de tiempo “libre” para dedicar a la política, y por la distinción entre el sur de la provincia (la cuenca del Golfo San Jorge) y el norte (el Valle del río Chubut). En nuestro trabajo rastrearemos estos procesos en momentos del nacimiento del sistema político chubutense, luego de la provincialización en 1957. Específicamente, prestaremos atención a la instancia de debate y redacción de la Constitución Provincial como un momento re-fundacional donde la asignación de esos espacios diferenciales se pone en juego. La discusión en torno al destino de la capital de la provincia resultará clave para el análisis de los elementos que sobredeterminan los argumentos técnicos del armado institucional. ABSTRACT In this article we argue that a utopian promise of fullness holds the communitarian life of the Chubut Province. It does so managing time and space, distributing social places, and giving the subjects a place in the community according to their capacities. This adds to a particularity in Chubut, since community life in the south of the province is strongly influenced by the tempo of the oil industry work and the difficulties for having time for politics outside the working place. This means that there is a considerable difference between the south (San Jorge Gulf Basin) and the north (Chubut River Valley), being the later the space of politics and the former the place for work. We will focus on the discussion of the provincial constitutional assembly as the moment that captures the regional differences as political identities. In particular, we will draw attention to the dispute over the place where the provincial capital would be located.

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. longicuneata. New geographic records are provided and distributional and biogeographic issues are discussed.
