[EN] Material is being collected towards a complete mapping of the ants of Spain, Balcanes and Portugal under the organisation of Professor A. de Haro, Universidad Autónoma, Bellaterra,. Barcelona. . To encourage collectors and facilitate recording, the following list of species and keys to the worker castes have been prepared. Both lists and keys are of a provisional nature as some of the earlier records are doubtful and in many cases correct synonymy has not been established and must await extensive revisionary studies. Keys to the worker caste only are possible at this time since are still unkno.wn for many of the species groups apart from Myrmica, Lasius and Formica. Both lists and keys include species known to occur in the French Pyrenees but not yet recorded for Spain since they are likely to be present and eventually discovered in adjacent areas on the Spanish side of tue frontier. Out of a total of 200 species usted here, a few have been omitted from the keys where specimens have not been available for examination and original descriptions have been inadequate to distinguish them clearly. At the same time, some species nafnes are included even where it is suspected that further study niay show them to be synonyms or where no certain records exist. It is hoped that collectors will point out defects in the keys and provide additional records so that a fuller and more accurate text can be prepared in due course.

[ES] El Prof. Dr. A. de Haro, de la Universidad Autónoma de Barcelona —Bellaterra—, organiza campañas de recolección de formícidos en la Península Ibérica e Islas Baleares, con el propósito de hacer un mapa de distribución lo más completo posible de estos himenópteros. Con el fin de alentar a los recolectores y facilitarles las determinaciones del material, he confeccionado la lista de las 200 especies citadas hasta ahora, así como claves de determinación de las obreras, ya que los dos machos de muchas especies son desconocidos.
