03AD87B2FFA4FFA3FCA5F8E9FECD2633.taxon	diagnosis	Diagnosis. The new genus can be distinguished from the other Moroccan stygobiont hydrobiids by its elon- 206 Youness Mabrouki et al. gated ovate shell with less than 5 whorls, its long penis, thickened at the basis with a bulbous part near the pointed penis tip. Heideella Backhuys & Boeters, 1974 has a slim, elongated conical shell with more than 5 flat whorls, a conical penis that is more or less elongated, wrinkled near its base, with one lobe, more or less developed and bulging. Atebbania Ghamizi, Bodon, Boulal & Giusti 1999 has an elongated conical shell with more than 5 whorls, with the penultimate whorl slightly broad- er than the body whorl, a penis with an apical stylet, one lobe bent downwards on its left side, and the penial duct running near the right side. Rifia Ghamizi, 2020 has a valvatoid shell and a bifurcated penis. The other genera are surface water molluscs and have eyespots and pigmented bodies.	en	Mabrouki, Youness, Taybi, Abdelkhaleq Fouzi, Methods, Peter Glöer Introduction Material And (2022): Mahrazia benlemlihi gen. et sp. nov., a new subterranean snail (Gastropoda: Hydrobiidae) from Morocco.

03AD87B2FFA4FFA3FCA5F8E9FECD2633.taxon	etymology	Etymology. The genus name ‘ Mahrazia ’ refers to its type locality: the Faculty of Sciences Dhar El Mahraz FSDM, located on the university campus Dhar El Mah- raz and covering an area of 6 ha. It mainly serves the region of Fez-Boulemane located in the northern center of Morocco.	en	Mabrouki, Youness, Taybi, Abdelkhaleq Fouzi, Methods, Peter Glöer Introduction Material And (2022): Mahrazia benlemlihi gen. et sp. nov., a new subterranean snail (Gastropoda: Hydrobiidae) from Morocco.

03AD87B2FFA6FFA2FF25F8D0FD7E20E0.taxon	etymology	Etymology. The species was named after Professor Mo- hammed Benlemlih (the Dean of the Faculty of Sciences, Dhar El Mahraz), in recognition of his encouragement and support for our research work and for his help in finding the new species.	en	Mabrouki, Youness, Taybi, Abdelkhaleq Fouzi, Methods, Peter Glöer Introduction Material And (2022): Mahrazia benlemlihi gen. et sp. nov., a new subterranean snail (Gastropoda: Hydrobiidae) from Morocco.

03AD87B2FFA6FFA2FF25F8D0FD7E20E0.taxon	description	Description Shell. Minute, thin-walled, elongated ovate, glossy and transparent when fresh, spire of 4.5 whorls growing regularly, and separated by a deep suture. Shell surface smooth, with growth lines that are hardly visible. Apex broad and flat. Aperture ovate with a sharp peristome. Umbilicus closed. Outer lip slightly sinuated in later- al view. The shell measurements (N = 9) are presented in Table 1. Since the number of individuals studied is quite small, these morphometric characteristics need to be completed by further catches of the new subterranean snail. Operculum. The corneous operculum is smooth and thin, and brown in colour. Soft parts morphology and anatomy. Body translucent when alive, white when preserved, pigment-less; tentacles very long and thin, without eyes. Penis long, thickened at basis with a bulbous part near pointed penis tip, four times longer than wide with folds at the basis.	en	Mabrouki, Youness, Taybi, Abdelkhaleq Fouzi, Methods, Peter Glöer Introduction Material And (2022): Mahrazia benlemlihi gen. et sp. nov., a new subterranean snail (Gastropoda: Hydrobiidae) from Morocco.

03AD87B2FFA6FFA2FF25F8D0FD7E20E0.taxon	distribution	Distribution. This new genus and species is known only from the type locality, which is a well located in the Faculty of Sciences Dhar El Mahraz (Fig. 7). It belongs to the Saiss aquifer system, one of the main aquifer sys- tems of Morocco, limited to the North by the Pre-Rif, to the East by the valley of the Oued Sebou, to the West by the tributaries of the Oued Beht and to the South by the Middle Atlas. It is formed by the deep Lias aquifer and the Quaternary groundwater. The water level is on aver- age at a depth of 50 m below the ground level.	en	Mabrouki, Youness, Taybi, Abdelkhaleq Fouzi, Methods, Peter Glöer Introduction Material And (2022): Mahrazia benlemlihi gen. et sp. nov., a new subterranean snail (Gastropoda: Hydrobiidae) from Morocco.
