Abstract
The first faunistic review of the caddisflies (Trichoptera) from the Iberian Peninsula, using as a reference the Limnofauna Europaea, was presented in 1987 and included 267 species. A comprehensive faunistic, nomenclatorial and systematically revised checklist of the Iberian caddsiflies was given in 1992 and included 294 species for the Iberian Peninsula and Balearic Islands.
Since 1992 our knowledge of the faunistic composition of some peninsular areas, especially of the meridional half and the Mediterranean region have considerably improved. It is now possible to update significantly the knowledge of caddisflies in the Iberian Peninsula and Balearic Islands. We critically reviewed the literature data and supplemented these with our recent new records. We also take into consideration some unpublished collections of the authors from different Iberian regions.
The checklist now contains 342 species (327, 185, 60 and 18 species from the Spanish mainland, the Portuguese mainland, Andorra, and the Balearic Islands, respectively), belonging to 75 genera and 22 families. Together, 4 families, i.e., Limnephilidae (23.7%), Hydroptilidae (14.9%), Leptoceridae (10.5%) and Rhyacophilidae (9.3 %), comprise 57% of the Iberian fauna.
