Hydraena (Hydraena) mouzaiensis Sainte-Claire Deville, 1909

Material examined. 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.
