%X Trichoptera is a very rich order in the Western Mediterranean, but knowledge of caddisflies in the Iberian Peninsula and northern Africa is still not complete. We present records of caddisflies collected in 114 sites of the Mediterranean climate region of the Iberian Peninsula and the western Rif. We also provide notes on ecological aspects and taxonomical remarks on some species. Atotal of 86 species were identified and 8 species extended their distribution range. Considering the four differentiated geological regions in the western Mediterranean Basin during the Tertiary, 60 species were collected in the Iberian plate region, 29 in the Transition, 30 in the Betic and 18 in the Rif. Local richness was not significantly different between the four regions but significant differences were found among several river ecotypes within regions. Temporary sites had lower local richness than other ecotypes in all regions except in the Rif, whereas headwaters had similar richness in any region regardless of their geology. The Rif region had the lowest Trichoptera richness, which is not only the result of the scarcity of faunistic studies in the area but also of the high frequency of temporary rivers and the isolation of the area. Our results suggest that conservation measures addressed to preserve the biodiversity of the Western Mediterranean should be enforced, especially in the Rif region. El orden Trichoptera es rico en especies en la zona del Mediterr¨¢neo Occidental, pero el conocimiento de este grupo en la Pen¨ªnsula Ib¨¦rica y el norte de ¨¢frica resta a¨²n de ser completo. Presentamos datos de tric¨®pteros recolectados en 114 localidades de la regi¨®n Mediterr¨¢nea de la Pen¨ªnsula Ib¨¦rica y del Rif occidental. Adem¨¢s, proporcionamos datos sobre la ecolog¨ªa de algunas especies as¨ª como notas taxon¨®micas. Se identificaron un total de 86 especies y el rango de distribuci¨®n aument¨® para 8 de ellas. Sesenta especies se recolectaron en la regi¨®n de la placa Ib¨¦rica, 29 en la de Transici¨®n, 30 en la B¨¦tica y 18 en el Rif, las cuatro regiones geol¨®gicas diferenciadas durante el Terciario en el Mediterr¨¢neo Occidental. La riqueza local no fue significativamente diferente entre regiones geol¨®gicas, pero s¨ª entre varios ecotipos fluviales. Los tramos temporales presentaron una riqueza local menor que los dem¨¢s ecotipos, excepto en el Rif, mientras que las cabeceras presentaban una riqueza similar en cada regi¨®n independientemente de su geolog¨ªa. Globalmente el Rif present¨® una menor riqueza de tric¨®pteros, lo que se explica no s¨®lo por la escasez de estudios faun¨ªsticos en l
