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.	en	Lamine, Smail, Lounaci, Abdelkader, Bennas, Nard (2019): Biodiversity and chorology of aquatic beetles (Coleoptera: Elmidae and Hydraenidae) in Kabylia (central-north Algeria).

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.	en	Lamine, Smail, Lounaci, Abdelkader, Bennas, Nard (2019): Biodiversity and chorology of aquatic beetles (Coleoptera: Elmidae and Hydraenidae) in Kabylia (central-north Algeria).

The species was recorded in Kabylia (the Djurdjura massif), the Atlas of the Blida (the Mouzaïa massif) and in Annaba (the eastern part of the country) (Ferro 1985; Kaddouri 1986; Aït Mouloud 1988; Lounaci 1987, 2005; Berthélemy et al. 1991; Lounaci-Daoudi 1996). In the study area, H. numidica inhabits springs, headwater streams and middle courses of rivers with rapid and moderate flow at altitudes ranging between 160 - 1200 m. It is an abundant species throughout the investigated area, collected in 92 % of the sampling sites. Despite its abundance, H. numidica is a threatened species in Algeria because of the habitat loss due to strong human pressure. Among 23 sampling sites in which the species occurred, 16 were subject to different types of adverse impact such as domestic water pollution, grazing, and extraction of water, sand and gravel. However, in Tunisia H. numidica is considered as a species under threat because of its very restricted distribution (Touaylia et al. 2009; Bennas et al. 2018), in only a few localities in the north-west of the country, as well as because of its low abundance (Touaylia et al. 2009).	en	Lamine, Smail, Lounaci, Abdelkader, Bennas, Nard (2019): Biodiversity and chorology of aquatic beetles (Coleoptera: Elmidae and Hydraenidae) in Kabylia (central-north Algeria).

H. pici is a fairly well-known species in the north of Algeria. It is reported in the massifs of Ouarsenis (west of the country), Mouzaïa and the Djurdjura (center of the country), and Edough massif (east of the country) (Aït Mouloud 1988; Lounaci 1987, 2005; Berthélemy et al. 1991). In this study, H. pici was captured in only three springs, under stones, gravel and pebbles with semi-submerged mosses. The altitudinal distribution of H. pici is restricted and ranges from 810 m to 920 m in the area under study. However, in Tunisia, the distribution area of H. pici is restricted to lowland streams (Touaylia et al. 2011). Like H. numidica, H. pici is considered as a threatened species in Tunisia, because of its very restricted distribution (in only a few localities in the north-west of the country) and its low abundance (Touaylia et al. 2009). One of the three springs, where it occurs, H. pici in Kabylia is impacted by grazing.	en	Lamine, Smail, Lounaci, Abdelkader, Bennas, Nard (2019): Biodiversity and chorology of aquatic beetles (Coleoptera: Elmidae and Hydraenidae) in Kabylia (central-north Algeria).

Chorotype. Endemic Maghrebian (Algeria and Tunisia). H. rivularis has previously been recorded from the north of Algeria, in the massifs of Ouarsenis in the west, Mouzaïa and Djurdjura in the center, and the Aurès in the east (Aït Mouloud 1988; Lounaci 1987, 2005; Berthélemy et al. 1991; Lounaci-Daoudi 1996). In the present study’s area, H. rivularis was captured, with very low abundances, in 15 sampling sites at altitudes between 160 m and 1200 m. It inhabits springs, headwater streams and middle courses of rivers with rapid and moderate flow. The majority of them have intermittent flow and are impacted by domestic water pollution, sand and gravel extraction. H. rivularis proved to be quite tolerant to organic water pollution (Lounaci 2005). In Tunisia, H. rivularis is considered a rare species (Touaylia et al. 2009; Bennas et al. 2018).	en	Lamine, Smail, Lounaci, Abdelkader, Bennas, Nard (2019): Biodiversity and chorology of aquatic beetles (Coleoptera: Elmidae and Hydraenidae) in Kabylia (central-north Algeria).

Chorotype. Endemic Maghrebian. This species is found in Algeria, Tunisia, Morocco and Sicily. From Algeria, L. pilicauda is recorded from the mountain massifs of Mouzaïa and Edough (Jäch 1993). Our collection in the Djurdjura massif constitutes the first record of the species for Kabylia. In the studied rivers, L. pilicauda was captured among semi-submerged mosses, with low abundance under gravel and pebbles, in springs, headwater streams and middle courses of rivers, at altitudes between 500 m and 1200 m. For seven sites where it occurs, L. pilicauda in Kabylia is impacted by grazing, domestic water pollution and water extraction. In Morocco, it is found in large mountain massifs such as oriental region and the Atlas Mountains, at altitudes between 244 m and 2000 m (Benamar 2015; Mabrouki et al. 2018). In Tunisia, it is located in several localities in the north of the country (Touaylia et al. 2009; Bennas et al. 2018) located at low altitudes between 2 m and 588 m.	en	Lamine, Smail, Lounaci, Abdelkader, Bennas, Nard (2019): Biodiversity and chorology of aquatic beetles (Coleoptera: Elmidae and Hydraenidae) in Kabylia (central-north Algeria).

In Algeria, it was recorded only from Mouzaïa, Atlas de Blida and the Djurdjura (Jäch 1990). In Kabylia, O. bonnairei is one of the most common Hydraenidae found in 64 % of sampling sites at altitudes between 370 m and 1450 m. The species inhabits three habitat types sampled in the study area. 12 out of 16 sampling sites where O. bonnairei occurs in Kabylia are impacted by grazing, domestic water pollution and water extraction. In Morocco the species was recorded from a few localities in the Rif, the Middle and High Atlas mountains (Bennas et al. 2001; Benamar 2015).	en	Lamine, Smail, Lounaci, Abdelkader, Bennas, Nard (2019): Biodiversity and chorology of aquatic beetles (Coleoptera: Elmidae and Hydraenidae) in Kabylia (central-north Algeria).

E. filum has been recorded in Algeria from a female specimen labeled on Alger Bonnair (Berthélemy 1979). Later Algerian records for this species come from the north of the country in Mouzaïa and the Djurdjura massifs, and from Chelia (Aurès) (Berthélemy 1964; Olmi 1976; Lounaci-Daoudi 1996; Lounaci 2005; Arab 2004). In this study, E. filum was captured in only three stations close to each other at middle-reach streams, with intermittent flow, located at altitudes between 200 m and 380 m. Two of them are impacted by domestic water pollution and sand and gravel extraction. In Morocco, its distribution is restricted to the Rif Mountains at altitudes between 590 m and 1450 m (Bennas & Sáinz-Cantero 2007; Benamar 2015) and in Tunisia it is confined to highland areas of the northern part of the country (Touaylia et al. 2010, 2011).	en	Lamine, Smail, Lounaci, Abdelkader, Bennas, Nard (2019): Biodiversity and chorology of aquatic beetles (Coleoptera: Elmidae and Hydraenidae) in Kabylia (central-north Algeria).

In North Africa, E. pygmaeus is recorded from Morocco, Algeria, and Tunisia. In Algeria, the species is reported from the northern part of the country in Mazafran, and Chéllif (Blida) (Arab 2004), and in the north-east from Ghar Rouban (Oran) (Berthélemy 1964). In Kabylia, the species is recorded from the Djurdjura massif (Aït Mouloud 1988; Lounaci-Daoudi 1996; Lounaci 2005). In this study, it was found extremely rarely in only middle-reach streams, with intermittent flow, located at altitudes between 160 m and 200 m. The two sites are impacted by domestic water pollution and sand and gravel extraction. In Spain, this taxon is considered relatively tolerant of organic pollution (Garcia-Críado & Fernández- Aláez 1995). In Slovakia E. pygmaeus prefers hyporhithral to epipotamal reaches of streams and smaller rivers in lowlands and hills around 300 m a. s. l. (Čiampor & Zaťovičová 2004). In Czechia, the species is considered very rare and endangered (Boukal et al., 2007). However, in Morocco, the species is widely distributed in the main areas of the country, where it inhabits headwaters, middle-reach streams, and is rarely found in lowlands, at altitudes between 10 m and 1820 m (Bennas & Sáinz-Cantero 2007; Benamar 2015).	en	Lamine, Smail, Lounaci, Abdelkader, Bennas, Nard (2019): Biodiversity and chorology of aquatic beetles (Coleoptera: Elmidae and Hydraenidae) in Kabylia (central-north Algeria).

Chorotype. Europeo-Mediterranean. The only previous Algerian records of this species were from Aurés in Chélia Forest, in Tiaret and in the Ouarsenis massif in Oran (Berthélemy 1964). In the Djurdjura massif, the species was captured in 12 sampling sites at altitudes between 290 m and 1200 m. The present study’s collection constitutes the first record of this species in Kabylia. The species is common in Morocco. It is found in the main areas of the country at altitudes between 20 m and 3300 m in the High Atlas (Bennas & Sáinz-Cantero 2007; Benamar 2015). However, in Tunisia, L. intermedius is present in lowland streams (Touaylia et al. 2010, 2011). In Austria, the species is usually found in the hyporhithral and epipotamal zone (Jäch et al. 2005).	en	Lamine, Smail, Lounaci, Abdelkader, Bennas, Nard (2019): Biodiversity and chorology of aquatic beetles (Coleoptera: Elmidae and Hydraenidae) in Kabylia (central-north Algeria).

In North Africa, L. opacus is known only in Morocco and Algeria. The previous Algerian records of this species are from Mouzaïa and the Djurdjura massifs (Berthélemy 1964; Lounaci 1987, 2005; Aït Mouloud 1988; Lounaci- Daoudi 1996). During the present study, it was captured in five additional locations at altitudes between 160 m and 380 m in habitats of middle-reach streams, with intermittent flow. Four out of the five sites are impacted by domestic water pollution and sand and gravel extraction. In Morocco, although the species is recorded at altitudes between 60 m and 2500 m, it is more abundant at high altitudes (Bennas & Sáinz-Cantero 2007; Benamar 2015). In Austria, the species prefers warmer streams, approximately from the metarhithral to epipotamal zone (Jäch et al. 2005). In Czechia, the species was listed as critically endangered by Boukal (2005), and later as regionally extinct (Boukal et al. 2007).	en	Lamine, Smail, Lounaci, Abdelkader, Bennas, Nard (2019): Biodiversity and chorology of aquatic beetles (Coleoptera: Elmidae and Hydraenidae) in Kabylia (central-north Algeria).

A22987E7FFEDFF93FF0C6650FF570264.taxon	distribution	Distribution. 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).	en	Lamine, Smail, Lounaci, Abdelkader, Bennas, Nard (2019): Biodiversity and chorology of aquatic beetles (Coleoptera: Elmidae and Hydraenidae) in Kabylia (central-north Algeria).
