- Acorigone zebraneusPublication . Borges, Paulo A. V.; Cardoso, PedroJUSTIFICATION: Acorigone zebraneus is a single-island endemic money spider species restricted to São Jorge island in Azores, Portugal (Borges et al. 2010). It is a rare species, with a restricted Extent of Occurrence (EOO) (4- 20 km²) and Area of Occupancy (AOO) (4-20 km²), but these values are suspected to be at the upper end of these estimates. There is a continuing decline in the EOO, AOO, extent and quality of habitat as well as the number of mature individuals as a result of the invasions of non-native plants and trampling of soil by dairy cows. The species occurs in a single patch of native forest at Topo Nature Reserve. In the past, the species has probably strongly declined due to changes in habitat size. The only patch of native vegetation where it occurs in under severe threat due to invasive plants and dairy-cattle disturbance. Therefore, we suggest as future measures of conservation: (1) a long-term monitoring plan of the species; (2) control of invasive species, and (3) restrict the access of cattle. The species is assessed as Critically Endangered (CR).
- Aprostocetus azoricusPublication . Nunes, Rui; Borges, Paulo A. V.JUSTIFICATION: Aprostocetus azoricus is an endemic eulophid wasp species of the Azores (Portugal), having been present at least historically on Flores island. From the historical data, this species had a very small Extent of Occurrence (8 km²) and Area of Occupancy (8 km²). It is possible that this species has declined in the past as a result of human activity, but the present situation of this species needs to be further assessed and further research is needed into its population, distribution, threats, ecology, life history and indigenous host species. Conservation/restoration of native habitats, as well as invasive plant species control, could potentially aid this species' conservation. Based upon the lack of recent data regarding this species population, distribution, threats, ecology and hosts, this species is assessed as Data Deficient (DD).
- Atrometoides nigerrimusPublication . Nunes, Rui; Borges, Paulo A. V.JUSTIFICATION: Atrometoides nigerrimus is an endemic ichneumonid wasp species of the Azores (Portugal), being present historically (at least) on S. Miguel island. From the historical data, this species may have had a very small Extent of Occurrence (8 km²) and Area of Occupancy (8 km²), and it is possible that this species has declined in the past as a result of human activity. However, the present situation of this species needs to be further assessed, and further research is needed into its population, distribution, threats, ecology, life history and indigenous host species. Conservation/restoration of native habitats, as well as invasive plant species control, could potentially aid this species' conservation. Based upon the lack of recent data regarding this species population, distribution, threats, ecology and hosts, this species is assessed as Data Deficient (DD).
- Bradysia truncorumPublication . Nunes, Rui; Borges, Paulo A. V.JUSTIFICATION: Bradysia truncorum is an endemic species of the Azores (Portugal), being present, at least historically, at a site on Flores island. From the historical data, this species may have a very small Extent of Occurrence (8 km²) and Area of Occupancy (8 km²), and it is possible that this species has declined in the past as a result of human activity. However, the present situation of this species needs to be further assessed, and further research is needed into its population, distribution, threats, ecology and life history. Conservation of native wet and boggy grasslands and semi-natural pastures could potentially aid this species' conservation. Based upon the lack of data regarding this species population, distribution, threats and ecology, this species is assessed as Data Deficient (DD).
- Canariphantes junipericolaPublication . Borges, Paulo A. V.; Cardoso, PedroJUSTIFICATION: Canariphantes junipericola is a single-island endemic species restricted to Flores (Azores, Portugal) (Crespo et al. 2014). It has a very small Extent of Occurrence (EOO = 4-12 km²) and Area of Occupancy (AOO = 4-12 km²), but the value is assumed to be at the upper end of this estimate. The species is rare and only known from a single subpopulation in the Natural Forest Reserve of Caldeiras Funda e Rasa. The surrounding area is highly invaded by alien plants. In the past, the species has probably strongly declined due to changes in habitat size and quality. Currently, invasive plants are changing some of the areas and decreasing the quality of the habitat. Based on Ferreira et al. (2016) the habitat will further decline as a consequence of climate change. Therefore, we suggest as future measures of conservation: (1) regular monitoring of the species; and (2) control of invasive plant species. Based upon the small geographic range of the species and continuing decline of its habitat area and quality, it is assessed as Critically Endangered.
- Carabodes azoricusPublication . Nunes, Rui; Borges, Paulo A. V.JUSTIFICATION: Carabodes azoricus is an endemic species of the Azores (Portugal), having been described from one location in Terceira island. From the species' description, it potentially has a very small Extent of Occurrence (4 km²) and Area of Occupancy (4 km²), but these are likely underestimates, as this species probably has a wider distribution through the soil component of the island. It can be assumed that this species is affected by human activities and invasive plant species, which alter the natural structure and composition of the soil. Future climatic changes and increased risk of droughts will also affect this species. The present situation of this species needs to be further assessed and further research is needed into its population, distribution, threats, ecology and life history. Conservation of natural habitats and invasive species control could potentially aid this species conservation. Based upon the incomplete knowledge regarding this species population, distribution, threats and ecology, this species is assessed as Data Deficient (DD).
- Chirothrips azoricusPublication . Nunes, Rui; Borges, Paulo A. V.JUSTIFICATION: Chirothrips azoricus is endemic to São Miguel (Azores, Portugal). It has a very small Extent of Occurrence (EOO = 8 km²) and Area of Occupancy (AOO = 8 km²). There is a continuing decline in the EOO, AOO, extent and quality of habitat as well as the number of mature individuals as a result of the invasions of non-native plants; and, based on this threat, the species occurs only at one location. Therefore, the species is assessed as Critically Endangered (CR). We suggest as future conservation measures: (1) regular monitoring of the species; and (2) control of invasive species, namely Hedychium gardnerianum and Clethra arborea.
- Dinotrema azoricumPublication . Nunes, Rui; Borges, Paulo A. V.JUSTIFICATION: Dinotrema azoricum is an endemic species of the Azores, Portugal. It is known only from the holotype, collected on São Miguel in 1938, in a (currently) highly disturbed area. From the historical data, it potentially has a very small Extent of Occurrence (16 km²) and Area of Occupancy (16 km²). This species has possibly declined in the past as a result of human activity, but the present situation of this species needs to be further assessed and further research is needed into its population, distribution, threats, ecology and life history. Conservation of native vegetation could potentially aid this species' conservation. Based upon the unknown distribution, threats and ecology, this species is assessed as Data Deficient (DD).
- Diversity of Lepidoptera recorded in a forest nursery of Nordeste county on São Miguel Island (Azores)Publication . Vieira, Virgilio; Oliveira, Luísa; Soares, António O.; Borges, Paulo A. V.; Borges, Isabel; Tavares, JoãoThe diversity of moth species (Insecta, Lepidoptera) recorded in the forest nursery of Nordeste county on São Miguel island (Azores) is given. Adults were sampled between March and December 2019 using three methods: (i) light trap to caught Noctuidae species, (ii) open-sided delta trap baited with a synthetic female sex pheromone lure to attract Epiphyas postvittana males and (iii) entomological net to identify microlepidopteran moths. A total of 10160 adults belonging to 33 lepidopteran species were recorded and listed by families, including: Argyresthiidae 1 (3%), Crambidae 4 (12%), Erebidae 1 (3%), Geometridae 5 (15%), Noctuidae 18 (55%), Sphingidae 1 (3%), Tineidae 1 (3%), and Tortricidae 2 (6%). The families Noctuidae, Geometridae and Crambidae were the most diverse. Those with the highest abundance of adults was the Noctuidae family followed by the Crambidae, Trotricidae and Tineidae. The number of caught adults was consistently higher during spring and summer, decreasing sharply in late fall. For 14 species caught in the light trap the adult sex ratio was favorable to females, except for Xestia c-nigrum which was favorable to males. An analysis of the colonization status, feeding and primary hosts of these endemic, native or exotic moth species suggests that plants reared in forest nurseries, being attacked by such insects, facilitates our understanding of the diversity of lepidopterans that establish in Laurel Forest environments and to what extent there is a need to monitor and control them mainly with biological control agents.
