GEOGRAPHICAL DISTRIBUTION AND ECOLOGY. — Protonemura talboti is a North African endemic species restricted to the Western part of Maghreb from the Moroccan Rif, Middle and High Atlas, up to the Algerian Blidean Atlas (Fig. 11). It occurs in various mountain brooks and springs of the Middle and High-Atlas from 85 m to 2900 m ( Vinçon & Muranyi 2009). We collected it for the first time in the central part of Algeria (Blidean Atlas), between 140 m and 1250 m (Fig. 12). The emergence period is very extended ( XI-VIII).

DIAGNOSIS. — In the male, the outer lobe of the paraprocts has a characteristic ventral finger-shaped expansion with a strong spine at the tip ( Fig. 6 B-D). The epiproct is slender at the tip ( Figs. 6A , 9A, B ), while in P. algirica algirica and P. algirica bejaiana , it is much stronger at the tip, with wide apex ( Fig. 7D, F ).

GEOGRAPHICAL DISTRIBUTION AND ECOLOGY. — Protonemura algirica algirica is an endemic subspecies occurring in Central Algeria (Blidean Atlas and Kabylian Djurdjura) ( Lounaci & Vinçon 2005) (Fig. 11). We collected it in Small Kabylia (Béjaia) and in the Aures region (Batna) (Fig. 12), that confirms the reports of Aubert (1956) in the same region. It seems to be absent from the Blidean Atlas where it could be replaced by P. talboti . In the El Kala region and in Tunisia, it is replaced by P. algirica bejaiana .

The Moroccan specimens previously assigned to P. algirica from the Rif belong to P. berberica or P. talboti (in Aubert, Sánchez- Ortega and Berthélemy collections); those from the Middle Atlas belong to P. dakkii Vinçon & Muranyi, 2009 or P. talboti (in Aubert, Berthélemy and Dakki collections), and those from the High Atlas remain problematic since the Moroccan paralectotypes (ZML) are actually lost and since all studied specimens from the High Atlas belong to P. talboti ( Vinçon & Muranyi 2009) .

In the Djurdjura Massif (Kabylia), Protonemura algirica algirica occurs in mountain watercourses (480-1300 m) ( Lounaci & Vinçon 2005), and according to our own collecting, it occurs in brooks and rivers above 1000 m and appears to be rheophilic and crenophilic. The adults emerge in spring (III-IV).

DIAGNOSIS. — In the male, the outer lobe of the paraprocts has a wide rounded ventral expansion with a strong spine at the tip and a dorsal rounded expansion carrying two or more spines ( Fig. 9 B-D). The epiproct is nearly rectangular at the tip ( Figs 7C, D ; 9A ), while in Protonemura talboti , it is much slender at the tip ( Fig. 7A, B ).

GEOGRAPHICAL DISTRIBUTION AND ECOLOGY. — Protonemura algirica bejaiana is an endemic subspecies from the Central Maghreb (W Tunisia and E Algeria) (Fig. 11). In Algeria, it is restricted to the El Kala region (Fig. 12) and it is replaced by P. algirica algirica in the Kabylian Djurdjura. In Tunisia, it occurs in brooks and brooklets at moderate altitudes (350-600 m) in the Khroumirian mountains ( Vinçon & Muranyi 2009). We collected it in lowland watercourses (below 200 m), but having the same characteristics as mountain brooks (slope, speed, rough substratum and dense riparian vegetation). The adults emerge in winter and spring ( XI-V).

DIAGNOSIS. — The male of P. algirica bejaiana differs from that of P. algirica algirica in the shape of the outer lobe of the paraprocts, having no spines on the dorsal expansion ( Fig. 10 B-D), while in P. algirica algirica it carries two or more spines ( Fig. 9 B-D). The epiproct tip is slightly more enlarged in P. algirica bejaiana ( Fig. 7F ) than in P. algirica algirica ( Fig. 7D ), but this character is rather variable. The females of both subspecies are similar.
