Hydropsyche incognita Pitsch 1993

<i>Hydropsyche incognita</i> Pitsch 1993a <p> <i>Hydropsyche incognita</i> was first described from Germany (Pitsch 1993a). It is a known species with a large distribution in many European countries (Serafin & Cios 2005) but a new species for Algeria and for the Maghreb. It was recorded at two sites of the El Harrach Wadi. The larva of this species has been described and diagnosed by Fischer & Neu (2002), Múrria <i>et al</i>. (2010), Neu & Tobias (2004), Statzner & Mondy (2009), Vieira-Lanero (2000), Waringer & Graf (2011), and Zamora <i>et al</i>. (2017).</p> <p> Characteristic features of the larva of <i>H. incognita</i> are dark brown body color, a straight anterior edge of the frontoclypeal apotome, and a light oral spot and a clear dark Y-shaped patch in the central area of the frontcypeus. <i>Hydropsyche incognita</i> also has a submentum with its lateral lobes elongate and its anterior margin with a small protuberance. Posteroprosternites are darkly pigmented. Abdominal segment VII has gills.</p> <p> Although it is likely our larvae belong to <i>H. incognita</i>, we would like to see the identification confirmed by catching adults as well.</p> <p> <b>International literature records.</b> AUSTRIA (Waringer & Graf 1997).

Distribution. Cheumatopsyche atlantis has been reported in Algeria and Morocco (♂); C. lepida in Algeria (♂), Italy (♂), Morocco (♂), Portugal (♂), Spain (♂) and Tunisia (♂). Comment. The genus Cheumatopsyche was described for the first time in North Africa by Lestage (1925). He identified larvae collected at Kerma Wadi near Algiers as “ Hydropsyche lepida.” Gauthier (1928) gave the same name to larvae from different Algerian wadis. Navás (1930) described a female of “ Hydropsychodes lepida ” found at Tinmel (western High Atlas, Morroco). Dakki (1982) reported only C. atlantis and signaled that C. lepida is much closer to the southern African species C. afra (Mosely 1935) than to the European species C. lepida. Lounaci et al. (2000) and Malicky & Lounaci (1987) sampled C. atlantis in the Great Kabylia (Aissi Wadi) and Arab et al. (2004) collected C. lepida in northwestern Algeria (Chelif Basin). Malicky (2005) has considered C. atlantis to be a synonym of C. lepida. Bonada et al. (2008) showed some differences: The hairy areas of C. atlantis are less conspicuous than in C. lepida and mostly limited to the anterior margin of the pronotum. Thus, they considered that C. atlantis is different from C. lepida, but more individuals need to be collected to ensure that C. atlantis is a valid species. During our survey, we were not able to identify the larvae to species. Catching mature pupae or matching identifiable imagoes with larvae using genetic methods will be necessary to identify them.Published as part of Khettar, Sihem, Haouchine-Bouzidi, Nawel, Kherbouche-Abrous, Ourida, Radi, Nora, Elalami, Majida & Beladjal, Lynda, 2022, Taxonomy and Distribution of Trichoptera in El Harrach Wadi (Northcentral Algeria) with the First Record of Hydropsyche incognita in North Africa, pp. 482-500 in Zootaxa 5120 (4) on pages 486-488, DOI: 10.11646/zootaxa.5120.4.2, http://zenodo.org/record/639289

Hydropsyche fezana Navas 1932

Hydropsyche fezana Navás 1932 Hydropsyche ouederoum Botosaneanu 1975 was synonymized with this species by Dakki (1978), but the synonymy was questioned by Botosaneanu (1999). Although Arab (2004), Bemmousset et al. (2021), and Sekhi et al. (2016) reported this species from Algeria, no taxonomical study was done. More study is needed to resolve this synonymy question.

Hydropsychidae Curtis 1835

Family HYDROPSYCHIDAE Curtis 1835 Hydropsychidae appears to be a relatively well-diversified group in Algeria. Genera and species occupy a wide range of habitats from brooks to large rivers (Illies 1953). Three genera of this family are present in El Harrach Wadi: Cheumatopsyche Wallengren 1891, Diplectrona Westwood 1839, and Hydropsyche F.J.

Taxonomy and distribution of Trichoptera in El Harrach Wadi (Northcentral Algeria) with the first record of Hydropsyche incognita in North Africa

Data on the caddisfly fauna of Algeria are incomplete and the available information concerns only some regions. In the present contribution, new distribution data on Trichoptera in El Harrach Wadi are given.
