<i>Hydropsyche nador</i> sp. n. (Trichoptera: Hydropsychidae), a new species of the <i>Hydropsyche guttata</i> species cluster from Morocco

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, 1936 Navás, L. (1936), ‘Insectos de Berbéria. Ser. 12’, Boletín de la Sociedad Entomológica de España (Madrid), 18, 77–100. [Google Scholar] and H. resmineda Malicky, 1977 Malicky, H.

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, 1834 Pictet, F.J.
