Distribution:
This recently described species was previously known only from
Algeria
, where it was confined to the westernmost part of the Algerian coast (
Glöer 2019
;
Glöer
et al.
2010
). We reported for the first time in
Morocco
, where it is confined to the easternmost of the country. Indeed, the species was found in the catchment area of the Nador lagoon, the massif mountain of Gourougou and the wetland of the Moulouya River mouth at Saidia (
fig. 1
).

Habitat:
The species can be found in a wide range of habitats and in different physicochemical conditions of the water. It was collected from natural and artificial watercourses of low altitudes, sometimes highly charged with organic matter as Selouan River (
fig. 10
), high altitude springs and finally from slightly brackish ponds alongside of the Mediterranean coast.
Associated species:
Physella acuta
,
Ancylus fluviatilis
,
Lymnaea truncatula
and
Planorbarius metidjensis
