In North Africa, the nominotypical subspecies is known from Morocco , Algeria and Tunisia (Jäch & Kodada 2016, Jäch et al . 2016). In Algeria , the species was recorded by Gauthier (1928) and recently by Arab (2004) in the west in Chélif wadi and in the center in the Mouzaïa massif. In Kabylia, it was found at the Djurdjura massif (Lounaci 2005). Its occurrence in the study area is limited to four sampling sites corresponding to three different habitat types : headwaters, middle-reach streams and springs, where it was captured with low abundance. Furthermore, their habitat is threatened by domestic water pollution and sand and gravel extraction. In Morocco , S. consobrina is reported from the Rif, the Middle Atlas, and oriental and central plateaus ( Chavanon et al. 2004 ; Bennas & Sáinz-Cantero 2007 ; Benamar 2015 ). In Tunisia , S. consobrina was reported from the north ( Boumaiza 1994 ), but not recaptured during the study of Touaylia et al. (2010) . Rare throughout most of its entire distribution range ( Przewoźny et al . 2011 ), it is an endangered species, extinct or critically endangered in Czechia ( Boukal et al . 2007 ), and vulnerable in the Iberian Peninsula ( Ribera, 2000 ).
