Étude d’un groupe d’espèces nettement sympatriques de Wormaldia McLachlan de l’ouest de la péninsule Ibérique (Trichoptera)

Considerations on a group of three related but perfectly distinct species of Wormaldia McLachlan, which have a clearly sympatrical distribution in the mountain streams of the western parts of the Iberian Peninsula (Galicia and Portugal). Two of these species, W. lusitanica and W. cantabrica, are here described as new.
