Resumo: O estudo de formicideos em Portugal, apesar de nao ser propriamente recente, nunca recebeu uma atencao profunda. Neste trabalho, colige-se as citacoes desta familia para Portugal Continental e Ilhas e elabora-se para cada especie uma relacao dos artigos onde e citada e dos locais para onde e citada. Ate a data, estao citados para Portugal Continental cento e seis especies, dezoito para o Arquipelago da Madeira e doze para o Arquipelago dos Acores. Palabras chave: Formicidae, Catalogo, Portugal, Madeira, Acores. Catalogue of the Formicidae of Continental Portugal and Islands

espanolEn este articulo actualizamos las citas de Formicidos que existen para Sierra Nevada, los cambios que se han producido en la taxonomia, asi como las posibilidades de errores en la identificacion de algunas de las especies citadas en la literatura clasica. Las respectivas modificaciones y las nuevas aportaciones, elevan el numero de especies de Sierra Nevada a un total de 87, de las que tres de ellas Tapinoma simrothi, Lasius emarginatus y Formica sanguinea quedan como dudosas. De todas ellas, 22 representan nuevas citas para este macizo y una de ellas es ademas nueva cita para Andalucia: Lasius meridionalis. Una comparacion con otros macizos similares y de los que existen datos publicados (Sierra de Guadarrama y Sierra de Cazorla), asi como con el nu- mero total de especies conocidas para Andalucia y Espana peninsular, situa a este macizo como uno de los mas ricos de toda Andalucia, seguido, de cerca, por la Sierra de Cazorla. Con 15 especies menos que la Sierra de Guadarrama, alberga alrededor de un tercio de las existentes en Espana peninsular. Sin embargo el numero de endemismos es muy bajo, con solo una especie, lo que probablemente se deba a que la region cacuminal (por encima de los 2800 metros) esta practicamente desprovista de hormigas y a que es esta region la que suele proporcionar las tasas mas altas de endemicidad en las montanas. EnglishIn this paper we revise the current records of Formicidae of Sierra Nevada, and include the changes carried out in the taxonomy of the family as well as indicate the possible misidentifications of species in previous records cited in the literature. With these modifications and new contributions, the number of species in Sierra Nevada is raised to 87, three of them, Tapinoma simrothi, Lasius emarginatus and Formica sanguinea remaining still as uncertain records. Out of the total number of species, 22 represent new records from this massif and one of them, Lasius emarginatus, is also a new record for Andalusia. A comparison with previous papers studying the ant fauna of similar massifs, as Sierra de Guadarrama and Sierra de Cazorla, as well as the total number of known species of Andalusia and peninsular Spain, shows that the Sierra Nevada massif is one of the richest of Andalusia. It comprise almost one third of the total number of species of peninsular Spain and 15 species less than Sierra de Guadarrama. However, the number of endemics in Sierra Nevada is very low, only one species being an endemic, probably due to the fact that the cacuminal region (over 2.800 m) in this massif is practically lacking ants, whereas this region usually shows the highest rates of endemic species in mountain regions.

Myrmica cagnianti, a new ant from North Africa (Hymenoptera, Formicidae).Myrmica cagnianti, a Moroccan ant, is proposed as a new species. It is characterized by its scape without lobulated extension, fine pilosity, absence of tibial spurs 11 and I1I and the shape of the petiole node. Differences from M. aloba Forel, M. specioides Bondroit and M. scabrinodis Nylander are described. The males of this new species are very similar to M. scabrinodis males. Cephalic indices provide a good way to discriminate between M. cagnianti and related species. The social parasite Myrmica kabylica (Cagniant) has been found in a nest of this new species, constituting the second record for this rare ant.
