THE DRAGONFLIES OF SERRA DA ESTRELA NATURAL PARK, PORTUGAL (INSECTA, ODONATA) Sónia Ferreira, José Manuel Grosso-Silva & Pedro Sousa CIBIO-UP, Centro de Investigação em Biodiversidade e Recursos Genéticos, Universidade do Porto, Campus Agrário de Vair- ão, 4485-661 Vairão; PORTUGAL. – SF: [email protected]; JGS: [email protected]; PS: [email protected] Abstract: The state of knowledge of the odonatofauna of Serra da Estrela Natural Park (Portugal) is presented with comments. Eleven species are recorded for the first time from the Park, including the legally protected Coenagrion mercuriale (Charpentier, 1840) and new records of Oxygastra curtisii (Dale, 1834) are presented. Furthermore, past and present records of Aeshna juncea (Linnaeus, 1758) and Sympetrum flaveolum (Linnaeus, 1758) from Portugal are discussed, and analysed in the context of their distribution in the Iberian Peninsula. Conservation relevance of the Serra da Estrela Natural Park on Portuguese Odo- nata and its threats are discussed and the necessity of further studies pointed out. Key words: Odonata, faunistics, new records, conservation, Portugal, Serra da Estrela Natural Park. Los odonatos del Parque Natural de la Sierra de la Estrella, Portugal (Insecta, Odonata) Resumen: Se presenta con comentarios el estado del conocimiento de la fauna odonatológica del Parque Natural de la Sierra de la Estrella. Se citan por primera vez del Parque 11 especies, incluyendo la legalmente protegida Coenagrion mercuriale (Charpentier, 1840), así como nuevos registros de Oxygastra curtisii (Dale, 1834). Además, se discuten los registros pasados y actuales de Aeshna juncea (Linnaeus, 1758) y Sympetrum flaveolum (Linnaeus, 1758) de Portugal, analizándolos en el contex- to de la distribución de dichas especies en la Península Ibérica. La relevancia del Parque Natural de la Sierra de la Estrella pa- ra la conservación de los odonatos portugueses y sus amenazas son discutidas, destacando la necesidad de más estudios. Palabras clave: Odonata, faunística, nuevos registros, conservación, Portugal, Parque Natural de Sierra de la Estrella.
