Mont. SPECIMEN EXAMINED . — France . Haute-Corse, Barcaggio, temporary ponds d’A Cala, 30.IV.2017 , 5 m a.s.l., V. Hugonnot s.n. Remarks It was found in great abundance in the Corsican locality in a brackish Mediterranean pond with mix water supply (sea water and meteoric water). Riella notarisi , as most of species of the genus, is a typical species of clean, shallow temporary ponds ( Segarra-Moragues et al. 2014 ). It is a halotolerant subneutrophilous-basiphilous species (Dierβen 2001). The determination of the sexual condition may offer special difficulties since antheridia are difficult to locate; they are hidden in a profusion of vegetative appendages very close to the growing point at the margin of the developing wing. The accurate determination of Riella notarisi relies heavily on its monoecy ( Casas et al. 2009 ). Riella notarisi is an European-Mediterranean species, which distribution includes Central Europe ( Bischler 2004 ). In the Mediterranean Region it is recorded from the Canary Islands in Macaronesia; the Balearic Islands, Crete, Croatia , France , Greece , Portugal , Sardinia, Sicily and Spain in southern Europe; Algeria , Morocco and Tunisia in northern Africa ( Bischler 2004 ; Ros et al. 2007 ). In Southern France , it is recorded patchily in Hérault, Bouche-du-Rhône, and Var Departments ( Crozals 1903 ; Skrzypczak 2001 , erroneously sub Riella parisii Gottsche (specimen N° 1048 from French Groupe d’Échange des bryophytes, leg.
