Our work was based on a characterization of the physicochemical, bacteriological quality of the surface water using two water quality indices (WGQI and CCME-WQI), at 20 sites during spring and summer 2017. After the detection of the most polluted zones, a second study focused on the characterization of the concentrations of twenty-one heavy metals determined from the highest polluted sites (9 stations) during autumn 2018. The results obtained reflect a deficient ecological state, especially downstream.

Son caractère méditerranéen favorise l'installation d'une faune simulidienne. Le présent travail est basé sur l'étude de 1068 spécimens de simulies récoltés dans 19 sites prospectés le long de ce bassin versant. Quatorze espèces ont été identifiées durant toutes les saisons entre 2003 et 2005. Une checklist des simuliidae identifiées est fournie et la distribution géographique à l'intérieur et à l'extérieur du bassin de l'Oued Laou est discutée pour chacune des espèces. The Simuliid fauna (Diptera: Simuliidae) of the Oued Laou catchment area (Morocco). Abstract. The Laou Basin is a main hydrographic net in northern Morocco. Its Mediterranean character favours a significant simuliid fauna. The present work is based on a study of 1068 specimens, collected from 19 positive sampling sites distributed along this catchment area. In all, 14 species are recorded from all seasons during 20...

Treize genres ont pu être identifiés, dont 11 se révèlent nouveaux pour le Rif dont 7 pour le Maroc. Le nombre de genres d'Empididae actuellement connu à l'échelle du pays s'élève à 13. Mots-clés : Diptera, Empididae, biogéographie, Rif, Maroc. Abstract. A Preliminery generic list of Empididae is given based on materiel collected in the Rif (Northern Morocco). Among the thirteen reported, 11 are new for the Rif and 7 for Morocco. This inventory increases to 13 the total number of genus found until now in Morocco.

Northwest African material previously ascribed to the subspecies Nephrotoma guestfalica surcoufi ... more Northwest African material previously ascribed to the subspecies Nephrotoma guestfalica surcoufi (Pierre, 1925) proved to belong to two distinct morphological forms, the true N. g. surcoufi from Algeria, and Tunisia, and the here newly introduced Nephrotoma guestfalica vaillanti n. subsp. from Morocco. With the distinction of the new form, four subspecies of Nephrotoma guestfalica (Westhoff, 1879) are now recognized, all occurring in the western Palaearctic. An identification key for the males of the four taxa of Nephrotoma guestfalica s.l. is provided. The male terminalia of the four taxa are illustrated. The distribution of the four subspecies is summarized, based on material examined and published data. A map showing the currently known distribution of N. guestfalica surcoufi and N. guestfalica vaillanti is presented. Nephrotoma guestfalica guestfalica is recorded here for the first time from Croatia.

The four ecological zones are: Zone 1 (Estuarine zone including pools, ponds, lagoons and wet meadows, altitude 0-10 m); Zone 2 (Potamal, alt. 10-350 m); Zone 3 (Lower basin of streams and wadis (alt. 350-1000 m); Zone 4 (Upper basin of streams, wadis, springs and peat bogs, alt. >1000 m). An updated list of 256 species/taxa belonging to Chironomidae (Diptera) has been established which complements previous data for the chironomid fauna of Morocco. The list includes 72 (28%) new records for the fauna of Morocco, 21 (8%) undescribed species and probably 2 new genera (1 Orthocladiinae and 1 Tanytarsini). Spatial distribution of species by subfamilies is highlighted in the four ecological zones where faunal comparative results are: Bucho...

The species group is differentiated from other Hercostomus by the male mid femur bearing ventral tubercle at base, one subtriangular and one semirounded projections at middle of narrow cercus directed ventrally, peculiar hitching lock between hind tibia and basitarsus. Syntypes of H. exarticulatoides Stackelberg, 1949 are studied. Lectotype is designated for the latter species. Hercostomus tanjusilus Negrobov et Tsurikov, 1988, syn. n. is proposed as a junior synonym of H. exarticulatus (Loew, 1857). Photographs of H. exarticulatoides, H. exarticulatus and H. canariensis Santos Abreu, 1929 are published for the first time. A key for the species group is provided. The known distribution of H. exarticulatus group is briefly discussed.

The chironomid community collected is diverse enough and interesting, and rare species are present. Of a total of 141 identified taxa, 46 species have proved to be new for the Rif and 31 for Morocco. The chorological tendency is mainly Palaearctic and Mediterranean. The majority of the sites investigated belong to protected areas in the north of Morocco, such as SIBE Jbel Moussa, SIBE Jbel Tidirrhine, SIBE Jbel Bouhachem and Talassemtane National Park, which belong to the Intercontinental Reserve of the Mediterranean Biosphere.
