“…With the inclusion of the Seybouse River taxon (Samraoui et al, 2021), three new North African endemic Habrophlebia species await description. This new taxonomic development challenges the records of Habrophlebia consiglioi in Tunisia (Zrelli et al, 2011a) and probably those of Habrophlebia fusca in the Maghreb (Thomas, 1998).…”

“…alpinus and R. sartorii in the relict streams of Mount Ghora, part of the Algerian Kroumiria, contrasts with their rarity (B. gr. alpinus) or absence (R. sartorii) in the Tafna (Benhadji et al, 2019) and the Seybouse catchments (Samraoui et al, 2021). The Oued El Eurg river basin also hosts species such as Habrophlebia spH and N. rhithralis, both absent from the Algerian Kroumiria, the Seybouse River, and the Tafna River basin.…”

“…Knowledge of the ecology of Algerian mayflies has lagged far behind taxonomic progress, and ecological investigations have only recently been attempted (Gagneur & Thomas, 1988;Mebarki, Taleb & Arab, 2017;Bouhala et al, 2020;Bouhala et al, 2021;Samraoui et al, 2021). In contrast, the distribution of Moroccan and Tunisian mayflies along various environmental gradients has been under intensive investigation (Boumaïza & Thomas, 1986;Dakki, 1987;El Agbani, Dakki & Bournaud, 1992;El Alami & Dakki, 1998;Mabrouki et al, 2017).…”

1. Data on Maghrebian mayfly communities are scarce and fragmentary, but evidence of alterations of the North African riverine landscape depleting the freshwater biota is rapidly mounting.2. In contrast to the overexploited lowlands, the highlands of north-eastern Algeria are hotspots of freshwater biodiversity and the last refugia to micro-endemics, North African endemics, and Eurosiberian relicts. 3. The mayflies of relict mountain streams of north-eastern Algeria were investigated and 20 species or taxa in five families were recorded. Two species of the genus Habrophlebia and one species of Centroptilum are new to science, whereas two Rhithrogena species are new to Algeria, including the Numidian endemic Rhithrogena sartorii. 4. Co-inertia analysis suggested a highly significant co-structure between mayfly assemblages and habitats defined by altitude, flow velocity, bed width, water depth, and water conductivity. In addition, a Poisson generalized linear model indicated a strong positive relationship between species richness and water depth and a weaker negative one with bed width (stream size). The results are congruent with the hypothesis that habitat provides the templet that drives mayfly communities, and they support the use of mayflies as bioindicators in the implementation of monitoring schemes to assess the ecological integrity of Maghrebian freshwater biodiversity hotspots. 5. The upstream part of the Kebir-East river basin is subjected to forest fires, pollution, and flow alteration, whereas the downstream part, which includes the vast Mekhada marsh, is increasingly fragmented and invaded by alien fish species. Conservation efforts focusing on the management of Oued Kebir-East, a transboundary Maghrebian river, and the restoration of the Mekhada marsh, a Ramsar site, need to be launched during the United Nations Decade on Ecosystem Restoration (2021-2030).

“…In the Moroccan hydrographic networks, C. luctuosa prefers the lower and middle courses with substrate dominated by a fine grain size; it is only absent in the streams with strong currents and low temperatures. This species can colonize waters with high conductivity (1600 µS/cm) [24] and asserts itself as the most polluo-resistant species [71,72].…”

Recent research in various Moroccan areas allowed an update and a revision of the Moroccan Ephemeroptera checklist. In this case, 54 species are now listed, belonging to 10 families and 26 genera. The distribution of all studied species is discussed, as well as their biogeographical affinities. Moroccan Mayflies are characterized by a clear dominance of Mediterranean elements with a strong rate of endemism (33.4%).

“…Mayfly nymphs were collected using a dipnet (500 µm mesh size, 35 cm diameter) and by walking slowly and repeatedly across all micro-habitats (aquatic vegetation, rocks, leaf litters, riffles, runs, pools, flats, etc.) for ten minutes at each locality, as described in [18][19][20].…”

Taxonomy, Distribution and Life Cycle of the Maghrebian Endemic Rhithrogena sartorii (Ephemeroptera: Heptageniidae) in Algeria

Despite being recorded in Algeria since the nineteenth century, the genus Rhithrogena has never been the object of a taxonomical study and no identified species is known from this country. Investigations of the relict mountain streams of El Kala, north-eastern Algeria, have led to the discovery of a Rhithrogena population. Morphological and molecular analyses identified the species as the Maghrebian endemic Rhithrogena sartorii, so far known only from neighboring Tunisia. We report on the species’ distribution, status, and life cycle and discuss its potential role as a bioindicator in environmental monitoring.
