Chorotype . Endemic Maghrebian ( Algeria and Tunisia ). From Algeria , the species was recorded from the Edough massif and in Souk Ahras located in the country’s northeast ( Kaddouri 1986 ; Berthélemy et al . 1991 ). The captures in thirteen sampling sites in the Djurdjura massif, at altitudes between 370 m and 1450 m , include new sites in northern Algeria . It is the first record for Kabylia. In Tunisia , these species was collected at elevations from 7 m to 588 m ( Touaylia et al . 2009 ). The rheophilic species has been collected in the following habitat types : springs, headwater streams and middle courses of rivers, under stony substrates with rocks and gravel. This microhabitat provides a homochromy for avoiding predators ( Touaylia et al . 2009 ). Among 12 sampling sites where H. leprieuri occured, 11 were exposed to domestic water pollution, grazing and water extraction.
