Distribution. Palearctic species, widely distributed in the northern part of Morocco (L’Mohdi 2016). This element was recorded in the Moulouya River basin at the Mohamed V Dam and Taourirt’ vicinity (Chavanon et al. 2004). Our work considerably increased the records of its distribution in the study area (Fig. 10).
