In this article is described, for the first time, the odonatological fauna form the natural parks of Monfrague and Cor- nalvo (Extremadura, Spain) with regard to samplings carried out during spring an summer 2004. A whole of 32 species have been captured (28 in Monfrague and 22 in Cornalvo). The high number of species found supports the importance of these ar- eas for the conservation of odonates in Extremadura.
The genus Cerambyx Linnaeus, 1758 in Extremadura (SW Iberian Peninsula) (Coleoptera, Cerambycidae) In Extremadura (SW Iberian Peninsula) the plagues attributed to Cerambyx species are serious and frequent. One of these species (C. cerdo) is protected to international level. The purpose of this study was to determine the distributions of the Cerambyx species in Extremadura. Cerambyx spp. were sampled during late spring and summer 2005 in 65 sampling sites in Extremadura (SW Iberian Peninsula). Cerambyx cerdo was found in three localities in the north-east part of Extremadura. C. welensii is the one that presents greater distribution with 21 known localities. Finally, C. scopolii only appears in two localities.
Desde finales de primavera hasta finales de verano de 2005 se ha muestreado 52 localidades en Extremadura (suroeste de la Penindula Iberica) con objeto de localizar poblaciones de Lucanus . Se encontro en nueve de ellas, en las que el sustrato arboreo estaba dominado por robles. Estas localidades, junto con las citas previas, elevan a 16 el numero de cuadriculas de 10x10 km2 en klas que L. cervus esta presente en Extremadura. La fragmentacion del habitat y la expansion de nuevos cultivos (cerezo) son los prinicpales factores de amenaza para esta especie en la comunidad autonoma.
Resumen: Se ha estudiado la distribucion de tres especies de escarabeidos: Copris hispanus (Linnaeus, 1764), Scarabaeus sacer Linnaeus, 1758 y Oryctes nasicornis (Linnaeus, 1758), localizadas en la provincia de Badajoz (Extremadura, Espana). Se obtienen nuevos registros para las tres especies y se presentan los mapas de distribucion en cuadriculas UTM de 10x10 Km. La especie con mayor numero de citas es Copris hispanus, mientras que Scarabaeus sacer es la que ocupa un menor numero de localidades. Palabras clave: Distribucion, Scarabaeidae, Badajoz, Espana. Abstract: The distribution of three species of dung beetles: Copris hispanus (Linnaeus, 1764), Scarabaeus sacer Linnaeus, 1758 and Oryctes nasicornis (Linnaeus, 1758) from Badajoz province (Extremadura, Spain) has been studied. New registries for the three species are obtained and their corresponding distribution maps in UTM 10x10 km squares are showed. Copris hispanus is the species with the highest number of citations, whereas Scarabaeus sacer is the one that occupies a smaller number of localities.
