Fessia aouintii View in CoL n. sp. (fig. 3)
Material studied: Holotype: H = 0.7 mm, D = 1.2 mm, ZMH 140696 View Materials ; 5 paratypes ( ZMH 140697 View Materials ), 6 in coll. Mebrouki, 3 in coll. Glöer.
Type locality: Morocco, Aouinat El Hajjaj, Fez prefecture, 34°01'39.1"N 4°58'24.1"W, 16.02.2020 leg GoogleMaps .
Etymology: Named after the type locality.
Habitat: Aouinat El Hajjaj is a rheocenous natural spring, located at Fez prefectur at an altitude of 409 m above sea level. The grain size of the bottom consists of stones, pebbles and sand, the vegetation of the banks is very heterogeneous and highly disturbed. Located in the Oued Wisslane watershed near a weekly market ‘souk’, which has subjected it to very strong anthropogenic action, through solid and liquid waste, habitat loss and water abstraction. In addition, the entire area could be suffering from agricultural runoff and drainage of water. Consequently, the population of Fessia aouintii n. gen. n. sp. would be highly vulnerable, and it is arguably the most threatened hydrobid of Morocco. Major efforts are needed for its conservation, including studies on its biological and ecological knowledge.
Description
