    Omphreus (Elladomphreus) eggeri, new species from the Peloponnese with description of a new subgenus (Coleoptera: Carabidae, Omphreini)

    Full text link
    In this article the systematics of the genus Omphreus is revisited, describing a new subgenus for the Greek species previously attributed to Paromphreus. Elladomphreus n. subg. differs from Paromphreus in the lateral gutter of pronotum deep and narrow all along, with 2-6 pore punctures, the striae deep and impunctate, the elytral surface smooth and shiny, the mandibles even longer and thinner. A new species belonging to this group is also described: Omphreus (Elladomphreus) eggeri n. sp. was collected on the Oros Panachaiko near Kalanistra (northern Peloponnese) in an interstitial forest environment. O. eggeri shows an average size smaller than O. krueperi but larger than O. aetolicus, with mandibles very elongated, pronotum smooth, narrower at base than at apex, elytra narrow, subparallel, with clearly marked humeral angles and with several setigerous pore-punctures on stria 6 and interval 7

    First description of the female of Lamiogethes hastipenis Liu et al., 2020 (Coleoptera: Nitidulidae, Meligethinae)

    Full text link
    In this study, the female of Lamiogethes hastipenis Liu, Yang, Huang, Cline, Sabatelli & Audisio, 2020, is reported for the first time, based on recently collected specimens from its type locality in Shennongjia National Forest Park, Hubei Province, China. Dorsal and ventral pictures of both male and female, along with pictures of their genitalia, are provided. The larval hostplant of L. hastipenis (almost certainly in the family Lamiaceae) still results unknown

    Un “Medioevo eretico” alla periferia del Medioevo: il caso bizantino: Medieval studies, Byzantine studies, Historiography, Mediterranean Sea

    No full text
    This article aims to investigate the role attributed to the idea of Byzantium in the construction of both the idea of the Middle Ages and Medieval Studies. Despite the increasingly pressing need for historical disciplines to adopt a “Mediterranean” perspective, the Mediterranean Sea (described as “Lago di Tiberiade” by Giorgio La Pira) remains, in many respects, even beyond to the scholarly debate, a wall, rigidly configuring zones of center – that is, continental Europe – and peripheries, including the East. Also – but not only – because of this peculiar position, that of Byzantium has become, according to a definition by Silvia Ronchey, a “heretical Middle Ages”, an object that defines the Middle Ages from the outside, by contrast, though not in a logic of sharp opposition: a“periphery” that shapes the “center”. It seems nec essary, however, to supersede this approach and reflect on the multiplicity of peripheries (geographic, social, cultural, economic) that constitute the Middle Ages. Scholars are increasingly paying attention to these multiple peripheries, as they are persuaded that not in a homogeneous and linear narrative, but in small splinters juxtaposed to each other, a new contribution can be made to the concept of the Middle Ages.Using some historiographical works (15th-20th centuries) as sources, this paper will address both the contrived and anhomogeneous construction of the Middle Ages and the posthumous elaboration of the Byzantine experience, which ended in 1453. The analysis of the positions of the international scholarly community in recent years will be followed by some questions about the future status of Byzantine and Medieval Studies, in order to initiate a potential and necessary debate

    Il Centro di cultura proletaria della Magliana. Costruire appartenenze tra i giovani di un quartiere popolare romano (1971-92)

    No full text
    Between May and June 1971, the inhabitants of the Prato Rotondo slum were relocated to the newly built Magliana district. In an attempt to prevent the community from disintegrating, the new inhabitants set up the Centro di cultura proletaria: a space on the street, open to the neighborhood, which in almost twenty years of activity has involved hundreds of people. Similar to other places of aggregation, but with its own specificities, the Centro di cultura proletaria experimented with forms of contro-scuola. Through field investigations, the collection of life stories and collective writing, it provided tools for raising awareness of one’s condition and claiming rights, contributing to develop clearly defined social identities and local affiliations. Based on the analysis of various sources, this contribution delves into the practices of representation and self-representation generated in this specific context, following its transformations up to the threshold of the 1990s

    Analyzing urbanization and environmental change in Aïn Fakroun, Algeria using landsat imagery through Google Earth Engine

    No full text
    This study examines the spatiotemporal dynamics of land use and land cover, as well as their relationships with surface temperature, normalized difference vegetation index, and normalized difference building index, in Aïn Fakroun, Algeria, over 30 years from January 1 to December 31 of the years 1993 and 2023. Using advanced remote sensing tools and the Google Earth Engine platform, Landsat-5 imagery for the year 1993 and Landsat-8 for the year 2023 were analyzed to examine significant environmental and urban transformations induced by climate change and rapid urbanization. The main findings reveal a marked increase in urban areas (nearly 2%) and vegetation, accompanied by a reduction in bare land, from 94% to 43%. However, this growth has exacerbated the urban heat island effect, with Land Surface Temperature values increasing across all land cover categories. For example, the maximum land surface temperature increased from 41.54°C in 1993 to 46.66°C in 2023, indicating substantial regional warming. The study found an inverse relationship between the Normalized Difference Vegetation Index and land surface temperature, with vegetated areas exhibiting lower surface temperatures. A positive correlation between the Normalized Difference Vegetation Index (NDVI) and land surface temperature highlights the thermal effects of urbanization. Urban areas have expanded significantly, particularly in the center and south of the region, while vegetation and forest cover have increased slightly in the north. These changes suggest a landscape transformation shaped by urban growth and reforestation efforts. The results provide policymakers with actionable information, advocating for sustainable practices such as integrating green infrastructure and high-albedo materials to mitigate urban heat island effects and enhance resilience to climate change. This research contributes to the understanding of the interaction between urbanization, vegetation, and surface temperature and offers recommendations for sustainable urban planning in Aïn Fakroun

    Geological model of the Stiffe-San Martino d’Ocre ridge (Central Apennines, Italy); evidence of multiple factors driving a mountain-scale deformation

    No full text
    The following paper illustrates the geological model of the Stiffe-San Martino d’Ocre ridge, which features a morpho-structural setting attributable to a Deep-Seated Gravitational Slope Deformation (DSGSD) process. The model reconstruction is based on geological and geomorphological surveys accompanied by remote sensing, geomechanical characterization, and geophysical investigations. Based on the results of the multidisciplinary analyses, it can be supposed that the Stiffe-San Martino d’Ocre ridge is affected by a DSGSD process, as diagnostic morphologies are significant at surface. The geological survey highlighted that the main morphological scarp of Fonteavignone-Terranera, does not coincide with any of the tectonic elements that influence the morphological structure of the relief. On the other way, a possible morphogenetic role for karst processes can be hypothesized, as the mountain ridge features numerous sinkholes and dolines, and the Stiffe Caves. The morpho-evolutionary setting of the ridge can be summarised in three main phases: a first phase, when gravitydriven deformations favoured by the relief energy of the incised Aterno Valley, affected the tectonic discontinuities, causing the development of minor DGPV in the marginal sectors of the ridge; a second phase, during which karst processes dominated the ridge, facilitated by discontinuities, controlling local lateral unconfinement in the middle part of the ridge thus allowing the gravitational process to extend to the Fonteavignone-Terranera scarp; a third and last phase, when the infilling of the Aterno Valley has redefined the ridge morphology, leading the deformational process to a state of apparent quiescence

    Full text link
    Anophthalmus drpensis n. sp. is described from caves of Soriška planina (north-west Slovenia). This new species differs from the related species of the “Anophthalmus schatzmayri species group” by external morphology and by shape of the copulatory lamella of endophallus

    What’s on the menu today? First report of nectarivory for Rhynocoris cuspidatus (Hemiptera: Reduviidae)

    Full text link
    This study reports the first observation of nectarivory in the predator reduviid Rhynocoris cuspidatus (Ribaut, 1921) in Spain. One individual of R. cuspidatus was observed sucking nectar from a Jacobaea vulgaris Gaertn. inflorescence in a grassland meadow in Berrecil de la Sierra (Spain). Our observation suggested that R. cuspidatus can use floral resources to obtain sugar or moisture during extreme climate conditions, such as can occur during Mediterranean summer

    Myrmecophilus baronii Baccetti, 1966: biogeography and genetics (Orthoptera: Myrmecophilidae)

    Full text link
    The presence of the ant cricket Myrmecophilus baronii Baccetti, 1966 is reconfirmed from the island of Pantelleria (Italy, Sicilian Channel), while new evidence of population clusters from northwest Malta is brought to light. The species is known from three separate geographical areas within the Mediterranean, spatially isolated from one another by the sea. Malta and Tunisia lie on opposite flanks of the Strait of Sicily, while Pantelleria, an island volcano of Quaternary age, lies on the graben that bisects the central Mediterranean area. The occurrence of the species in these three locations underscores the relevance of island biogeography in respect to taxa that lack the capacity to disperse over long  distances unaided, as is the case of myrmecophilous crickets. The study considers passive dispersal, including sweepstakes routes, as a potential means of dispersal by M. baronii. It also includes an integrative systematics approach using both morphology and barcode sequencing of the 16S ribosomal RNA region and the cytochrome c oxidase subunit 1 (COI) gene. Subsequent phylogenetic analyses reveal that Myrmecophilus baronii, M. orientalis and M. ochraceus do not cluster with other Myrmecophilus species that had been DNA barcoded thus far. Given the species’ conservation status, notably its Habitats Directive designation as a priority species within European territory, this work provides new insight into habitat preferences and thus provides an important basis for conservation of this species
