Hydropsyche resmineda Malicky 1977

( Fig. 13 )

Material examined: Khemis Wadi (KH1): 1 fifth instar larva (UTA), 08.iii.2018 .

Description: Larva with body length 13 mm; yellowish to light brown body; reddish-brown transverse band located along anterior part of pronotum ( Fig.13A ); frontoclypeal apotome also bordered by reddish-brown stripe ( Fig. 13A ); head sub-rectangular; frontoclypeal apotome narrow with highly convex anterior edge ( Fig. 13B ; Dakki & Tachet 1987). Apotome with light continuous patch narrowed by dark transversal protrusions at insertion of cibarian muscles ( Fig. 13B ), posterior prosternites translucent ( Fig. 13D ), and lateral parts of submentum long and narrow ( Fig. 13C ).

Similarities also have been observed between the Algerian larva of H. resmineda and that of Morocco described by Dakki & Tachet (1987). However, important differences were noted in H. resmineda from a Tunisian larva described by Allaya (2003) ( Table 3). More individuals, especially adults, need to be collected to clarify the situation.

Distribution and ecology: Its distribution area is limited to the Maghreb ( Tobias & Tobias, 2008). It was listed from Algeria by Malicky (1983) and Malicky & Lounaci (1987). Boumaiza (1994) and Allaya (2003) recorded it in Tunisia, and Dakki & Tachet (1987) in Morocco. This species is known in Morocco between the Rif and the Atlas, where it lives between 200 and 1450 m a.s.l ( Dakki 1978) and in the Rif between 190 and 580 m a.s.l ( Hajji et al. 2013). In our study, the larva was collected at 854 m a.s.l. in a shaded microhabitat characterized by a slow current and heterogeneous substrate composed of mud and pebbles.
