During a period of nine years, from 2000 to 2008, two consecutive studies-one focusing on observations of adult Odonata, the other on collection of larvae-were carried out in the basin of the Guadiamar River in the southwestern Iberian Peninsula. In addition to monitoring Odonata, several environmental variables were assessed, including an index based on macroinvertebrate communities (IBMWP). In April 1998, this river system suffered from an accidental release of a large mass of toxic mining waste, which exterminated macroinvertebrates in the middle and lower parts and floodplain. Several years later, dragonfly communities in these areas were similar to those of unaffected upper reaches. Communities of sites less affected by general human impact were dominated by semivoltine anisopterans. In contrast, headwaters and river reaches where riparian forest had been destroyed many years ago and seasonality of river discharge was boosted by landscape management harboured chiefly uni-or bivoltine species, regardless whether a site had been affected by mining waste or not. Species assemblage was especially poor in lower river reaches that experienced permanent, diffuse urban and agricultural pollution. A few partivoltine species were recorded, but only in habitats with a high IBMWP index. It seems that over the long term, Odonata respond more to land use and catchment management than other groups included in the IBMWP index.

22Joint effects of climate warming and other stressors are potentially complex and difficult to 23 predict. In stream ecosystems, exotic riparian species have the potential to alter leaf-24 shredding detritivorous invertebrate assemblages and leaf litter breakdown due to 25 differences in the quality of litter inputs. This is the case for Eucalyptus plantations, which 26 are widespread, occurring along riparian corridors of streams around the world. We

A partir de una exhaustiva revisión bibliográfica y de nuevos datos aportados en este estudio se establece que el número de especies de tricópteros registradas en Andalucía asciende a 136, incluidas en 53 géneros y 17 familias. Este número equivale aproximadamente al 38% de las especies presentes en la península ibérica. Catagapetus mclachlani y Oxyethira falcata constituyen nuevas citas para Andalucía, así como el género Beraea. Se confirma asimismo la presencia de Stenophylax permistus. Además se menciona una nueva especie de Hydropsyche, otra de Helicopsyche y una probable nueva especie del género Agapetus. Las familias mejor representadas son Hydroptilidade (18%), Limnephilidae (17%), Leptoceridae (13%) e Hydropsychidae (13%). Con esta actualización se han registrado 86 nuevas citas provinciales, mejorando sensiblemente los inventarios de las provincias de Granada, Jaén, Málaga y Sevilla. Los tricópteros de las provincias de Almería y especialmente los de Huelva, permanecen sin embargo muy poco estudiados. El estudio biogeográfico llevado a cabo entre las ocho unidades geográficas propuestas muestra tres grandes dominios diferenciados: Sierra Morena, el Sistema Bético y la depresión del Guadalquivir. Contrariamente a lo que se podría pensar, la tricopterofauna de las sierras Béticas húmedas (Serranía de Ronda y Campo de Gibraltar) parece mostrar una mayor similitud con la de Sierra Morena. La fauna de tricópteros andaluza está formada mayoritariamente por componentes de origen europeo (más del 50%) y endemismos (42%), de los que un 60% son exclusivos de Andalucía. Estos datos muestran que, dentro de la península ibérica, esta región destaca como una zona importante de refugio y centro de especiación para los tricópteros.

The West Palearctic genus Schizopelex McLachlan 1876 is represented by eleven recognized species. The center of its distribution area is in Turkey, where seven species have been reported (Malicky 2004; Sipahiler 2005, 2012; Oláh 2010; Sipahiler & Pauls 2012). These 7 species are S. anatolica Schmid 1964, S. rhamnes Malicky 1976, S. sinopica Sipahiler 2012, S. yenicensis Sipahiler & Pauls 2012, S. boluensis Sipahiler 2012 (in Sipahiler & Pauls 2012), S. cachetica Martynov 1913a, S. pontica Martynov 1913b. Schizopelex cachetica and S. pontica have also been reported from the Caucasus and the Transcaucasia, respectively (Martynov 1913a, 1913b; Ivanov 2011). In addition, two species (S. huettingeri Malicky 1974 and S. persica Schmid 1964) are known from the Balkans and Iran, respectively. The two remaining species are distributed in the southwestern West Palearctic region (southwestern Europe): Schizopelex furcifera McLachlan 1880 has been reported from the northeastern Iberian Peninsula and the Pyrenees (González et al. 1992; Martínez-Menéndez & González 2010); Schizopelex festiva (Rambur 1842) is distributed throughout most of the Iberian Peninsula and the Maghreb (González et al. 1992; González & Martínez 2011). In this paper is described and illustrated for the first time a new species of Schizopelex from the southern Iberian Peninsula.
