Abstract

As a result of studies of material of Ecdyonurus from Spain, nymphs and adults of two new species, E. baeticus sp. n. and E. olgae sp. n., are described. Three species described by Navás must be considered as nomina dubia ( E. diversus Navás, 1923, E. excelsus Navás, 1927 and E. fluminum var. speciosus Navás, 1915). Variability in adults of E. venosus is figured and discussed.
