The Stoneflies (Plecoptera, Insecta) of the northwestern Iberian Peninsula

Abstract

73 species and subspecies are reported from the North West of the Iberian Peninsula, including 10 new taxa described in the last four years. 14 species are new for the Cantabrian Cordillera, 1 for Galicia, 9 for the Sierra de la Demanda and 2 for the Sierra del Moncayo. The systematic status of some species is modified: Protonemura pyrenaica pyrenaica and P. pyrenaica asturica are restored to specific level; Leuctra lusitanica is considered as a subspecies of L. lamellosa; Nemoura cinerea umbrosa is a valid subspecies of N. cinerea cinerea. The stonefly faunistic lists of the Cantabrian Cordillera, Galicia, Demanda and Moncayo are updated. Species distribution patterns and faunistic relations with the neighbouring regions are analyzed. Classification and ordination analyses based on species presence, enable identification of bioclimatic and biogeographical patterns of Plecoptera distribution in the North of the Iberian Peninsula.
