Abstract
In this paper, we describe a new species of the Hydropsyche angustipennis species group, Hydropsyche nador sp. n., from Selouan and Bni Snassen areas in Morocco. The males of the new species are closest to those of Hydropsyche maroccana Navás, Citation1936 and H. resmineda Malicky, Citation1977 but differ from them mainly in the shape of the apical part of phallus, dorsal keel of segment IX, and the shape of harpago. We also used the size of head, eyes, and occipital setal warts and interocular distance, as well as the associated ratios for species delimitation.
In total, ten species of the genus Hydropsyche Pictet, Citation1834 are now known from Morocco.
