(see description below).	en	Mabrouki, Youness, Glöer, Peter, Taybi, Abdelkhaleq Fouzi (2022): Idrisiella bourkaizensis gen. et sp. n., a new valvatoid snail (Gastropoda: Hydrobiidae) from Morocco.

03C687F766525B573957FB50D4CDFAD0.taxon	description	DESCRIPTION: The new taxa is clearly distinguished by the following combination of characters: the translucent shell is valvatoid with a wide-open umbilicus. The triangular penis has a bulbous basis, with a small outgrowth on the left side (Fig. 4). Shell shape and penis morphology define the new genus.	en	Mabrouki, Youness, Glöer, Peter, Taybi, Abdelkhaleq Fouzi (2022): Idrisiella bourkaizensis gen. et sp. n., a new valvatoid snail (Gastropoda: Hydrobiidae) from Morocco.

03C687F766525B573957FB50D4CDFAD0.taxon	diagnosis	DIFFERENTIAL DIAGNOSIS: The new genus can be distinguished from its Moroccan congeners by its triangular penis. Pikasia smenensis Taybi, Glöer et Mabrouki, 2021 (endemic to Ain Chqef and Smen springs) is with a simple penis, broad and elongate flat with an acute penis tip, the distal part of the penis with an elongated triangular blackish spot. Ifrania zerroukansis Glöer, Mabrouki et Taybi, 2020 (endemic to Lake Zerrouka) has long and slender cylindric penis, widened at the basis and tapered at the distal end with a pointed penis tip. Fessia aouintii Glöer, Mabrouki et Taybi, 2020 (endemic to Aouinat El Hajjaj spring) has small and flat penis with a broad basis and tapered at the distal end. Rifia yacoubii Ghamizi, 2020 (subterranean) has a penis with two small non-glandular lobes and without stylet. From the other Islamia species, the new genus can be distinguished by the penis which is bilobed in Islamia.	en	Mabrouki, Youness, Glöer, Peter, Taybi, Abdelkhaleq Fouzi (2022): Idrisiella bourkaizensis gen. et sp. n., a new valvatoid snail (Gastropoda: Hydrobiidae) from Morocco.

03C687F766525B573957FB50D4CDFAD0.taxon	etymology	ETYMOLOGY: The new genus Idrisiella is named after the medina of Fez which was the capital founded by the Idrisid dynasty between 789 and 808 of our era. Listed since 1981 as a UNESCO World Heritage Site, Fez was indeed, until 1912, the capital of the Kingdom of Morocco.	en	Mabrouki, Youness, Glöer, Peter, Taybi, Abdelkhaleq Fouzi (2022): Idrisiella bourkaizensis gen. et sp. n., a new valvatoid snail (Gastropoda: Hydrobiidae) from Morocco.

03C687F766515B563919FA14D4DAFAF2.taxon	biology_ecology	Habitat: Ain Bourkaiz is a large spring located at Moulay Yacoub province, about 14 km west of the city of Fez at an altitude of 540 m. A big part of the spring is arranged to supply drinking water. However, other small sources not reached by the arrangement still flowing naturally and feed the Bourkaiz River, where the new taxa can be found (Fig. 6). The water flows through a stony bottom before entering a large swamp.	en	Mabrouki, Youness, Glöer, Peter, Taybi, Abdelkhaleq Fouzi (2022): Idrisiella bourkaizensis gen. et sp. n., a new valvatoid snail (Gastropoda: Hydrobiidae) from Morocco.
