- The Arthropoda fauna of Corvo island (Azores): new records and updated list of speciesPublication . Vieira, Virgílio; Borges, Paulo A. V.; Karsholt, Ole; Wunderlich, JörgSe exponen los resultados de artrópodos (phylum Arthropoda) colectados y observados en la isla de Corvo, archipiélago de las Azores, durante los días 26.VII.1999 y 11-13.IX.2002. Con la inclusión de la literatura disponible, se citan 175 especies y subespecies (11.43% son comunes a las otras islas de las Azores), repartidas per 16 órdenes y 83 familias, de las que 32 son nuevas citas para la isla de Corvo. Phaneroptera nana Fieber (Orthoptera: Tettigonidae) se cita por primera vez para las Azores.
- New records of moths (Insecta, Lepidoptera) from urban gardens on Terceira Island with new data on recently introduced species to the AzoresPublication . Pérez Santa-Rita, Jose V.; Ros-Prieto, A.; Vieira, Virgílio; Karsholt, Ole; Gabriel, Rosalina; Borges, Paulo A. V.The urban Duque da Terceira Garden, in the main town of Angra do Heroísmo (Terceira, Azores), was investigated to describe the species composition of moths (Insecta, Lepidoptera). Moths were sampled with two methods: SLAM traps (between April and September 2017) and light trapping (two sessions in the summer of 2017). A total of 42 taxa were sampled with the addition of 19 new records for Duque da Terceira Garden, five of which were also new records for Terceira Island. The five species recorded as new for Terceira were subjected to an exhaustive taxonomic analysis. In addition, we revised the colonization status of some species. Our results show that urban gardens may help the establishment of exotic species and that it is necessary to monitor and control how these species established in urban environments.
- Updated Checklist of Arthropods from Azores (Portugal)Publication . Borges, Paulo A. V.; Lamelas-López, Lucas; Andrade, Rui; Lhoumeau, Sébastien; Vieira, Virgilio; Soares, António O.; Borges, Isabel; Boieiro, Mário; Cardoso, Pedro; Crespo, Luís C.; Karsholt, Ole; Assing, Volker; Schülke, Michael; Serrano, Artur R. M.; Quartau, José A.The data we present consists in an updated checklist of the Azorean arthropods. The checklist compile known records based on published literature, unpublished data, and new records at archipelago and island levels. This publication represents the most recent information about distribution of introduced, native and endemic arthropods in the Azores archipelago. Currently the total number of terrestrial arthropod taxa (species and subspecies) in the Azores is estimated of about 2417 belonging to 14 classes, 53 orders, 438 families, 1554 genera and 2397 species and 149 individual subspecies. The most diverse orders of Azorean arthropods are: Coleoptera (585 taxa), Diptera (422 taxa), Hemiptera (338 taxa), Hymenoptera (162 taxa), Lepidoptera (159 taxa) and Araneae (132 taxa). A total of 275 endemic taxa are currently known (231 species and 44 subspecies), belonging to 8 classes and 22 orders. São Miguel, Terceira and Pico are the islands with higher number of endemic species and subspecies. Compared to the other nearest Macaronesian archipelagos (Madeira and Canaries), the Azorean arthropod fauna is characterized by a lower percentage of endemism and a high proportion of exotic introduced species.
- An updated checklist of Azorean arthropods (Arthropoda)Publication . Borges, Paulo A. V.; Lamelas-López, Lucas; Andrade, Rui; Lhoumeau, Sébastien; Vieira, Virgilio; Soares, António O.; Borges, Isabel; Boieiro, Mário; Cardoso, Pedro; Crespo, Luís C.; Karsholt, Ole; Schülke, Michael; Serrano, Artur R. M.; Quartau, José A.; Assing, VolkerBACKGROUND: The Azores is a remote oceanic archipelago of nine islands which belongs to the Macaronesia biogeographical region hosting a unique biodiversity. The present Azorean landscape is strongly modified by the presence of man and only in small areas, where the soil or climate was too rough, have primitive conditions remained unchanged. Despite the fact that most of the Azorean native habitats are now lost, a large number of endemic species are still present and need urgent conservation. The present checklist of terrestrial and freshwater arthropods of the Azores Archipelago is based on all known published literature. The main goal of this work is to list, as rigorously as possible, all the known terrestrial and freshwater arthropods of the Azores. In this way, we are contributing to solve the ‘Linnaean’ shortfall, i.e. an incomplete taxonomic description of species-level diversity and the Wallacean Biodiversity Shortfall, the incomplete species distribution knowledge. NEW INFORMATION: The checklist includes new records of arthropods at island and archipelago levels that were published in the last twelve years. Compared to the last checklist of Azorean arthropods (Borges et al. 2010b), a total of 217 taxa (species and subspecies) are added. Currently, the total number of terrestrial and freshwater arthropod species and subspecies in the Azores is estimated to be 2420 taxa belonging to 14 classes, 53 orders, 440 families, 1556 genera, 2400 species and 149 individual subspecies. The most diverse orders of Azorean arthropods are: Coleoptera (585 taxa), Diptera (423 taxa), Hemiptera (338 taxa), Hymenoptera (163 taxa), Lepidoptera (159 taxa) and Araneae (133 taxa). A total of 276 endemic taxa are currently known (232 species and 44 subspecies), belonging to eight classes and 22 orders. São Miguel, Terceira and Pico are the islands with higher number of endemic species and subspecies. In the Azores, the number of native non-endemic taxa is 793 taxa, totalling 1069 indigenous taxa. Compared to the other nearest Macaronesian archipelagos (Madeira and Canaries), the Azorean arthropod fauna is characterised by a lower percentage of endemism (endemics/indigenous: 26% in Azores, 47% in Madeira Archipelago and 42% in Canary Islands) and a high proportion of exotic introduced taxa (39% in Azores, 19% in Madeira Archipelago and 8% in Canary Islands). Based on recent IUCN Red-listing of Azorean arthropods, a large fraction of the endemic taxa is under high threat.
