Contribución al conocimiento de los heterópteros (Insecta) de ríos de Navarra

The results of the captures of Heteroptera (Gerromorpha and Nepomorpha) in five rivers of Navarre are presented. A total of 91 Heteroptera belonging to four species (Aquarius najas, Aquarius paludum, Hydrometra stagnorum and Nepa cinerea) were identified. The capture of A. paludum is of particular interest, because it is recorded for the first time in Navarre.
