Chorotype. Endemic Maghrebian ( Algeria and Tunisia).

H. rivularis has previously been recorded from the north of Algeria, in the massifs of Ouarsenis in the west, Mouzaïa and Djurdjura in the center, and the Aurès in the east ( Aït Mouloud 1988; Lounaci 1987, 2005; Berthélemy et al. 1991; Lounaci-Daoudi 1996).

In the present study’s area, H. rivularis was captured, with very low abundances, in 15 sampling sites at altitudes between 160 m and 1200 m. It inhabits springs, headwater streams and middle courses of rivers with rapid and moderate flow. The majority of them have intermittent flow and are impacted by domestic water pollution, sand and gravel extraction. H. rivularis proved to be quite tolerant to organic water pollution (Lounaci 2005). In Tunisia, H. rivularis is considered a rare species ( Touaylia et al. 2009; Bennas et al. 2018).
