Contribution to the knowledge of Moroccan and Maghrebin stoneflies (Plecoptera).

An overview of Moroccan stoneflies is presented as an annotated summary of published and unpublished records from 115 localities. These records have resulted in an updated species list reflecting taxonomic corrections and noteworthy range extensions for several species. A total of 28 species, belonging to 15 genera and seven families, is now known from Morocco with the greatest diversity found in the Rif Mountains (23 species) and the lowest in eastern Morocco with three species. The majority of Moroccan stoneflies are typical Mediterranean species (86%). The Moroccan endemics comprise nine species (32% of the Moroccan fauna). The Plecoptera fauna of Morocco is compared to that of Algeria and Tunisia. Thirty-eight stonefly species are reported from the entire Maghreb region. Protonemura khroumiriensis Béjaoui & Boumaïza, 2009 is considered a synonym of P. drahamensis Vinçon & Pardo, 2006.
