Material examined: AA: 24-IV-2014 (3 exs.), KH: 14-VI-2014 (3 exs.), D1: 8-V-2013 (10 exs.), A6: 7-V-2013 (3 exs.), O1: 24-IV-2014 (4 exs.), O4: 24-IV-2014 (4 exs.), BO2: 26-VI-2014 (3 exs.), TG2: 18-V-2014 (3 exs.).

Chorotype: Endemic to Algeria.

The only previous Algerian records of this species were from Ouarsenis, the Djurdjura, and Mouzaïa massifs ( Berthélemy 1964; Lounaci 1987). The present survey expands the occurrence of the species in eight sampling sites belonging to Wadis Boubhir and Aïssi. Its altitudinal distribution ranges from 200 m to 1200 m. It inhabits springs, headwater and middle-stream reaches, with rapid and moderate, intermittent and permanent flow. The majority is impacted by domestic water pollution and sand and gravel extraction.
