A1 : 7-V-2013 ( 15 exs. ), A2 : 7-V-2013 ( 35 exs. ), O1 : 16-VI-2014 ( 34 exs. ), O2 : 16-VI-2014 ( 3 exs. ), O4 : 16-VI-2014 ( 5 exs. ), BO1 : 26-VI-2014 ( 3 exs. ), BO2 : 26-VI-2014 ( 3 exs. ). Chorotype . Endemic of Algeria . The previous Algerian record of H . mouzaiensis was based on a number of adult specimens from the north of the country in Mouzaïa (Atlas Blidéen), Ourasensis and the Djurdjura massifs (Kabylia of the Djurdjura), and in Souk Ahras ( Lounaci 1987 , 2005; Berthélemy et al . 1991 ). Published data (Lounaci 2005) and the current captures from the Bougdoura and Aissi under-basins show that H. mouzaiensis inhabits springs, headwater streams and middle courses of rivers with rapid and moderate flow at altitudes ranging between 500 m and 920 m . Five out of seven sampling sites were impacted by domestic water pollution.
