Treatment

Ifrania zerroukansis View in CoL n. sp. (fig. 2)

Material studied: Holotype: 1.1 mm high, 1.5 mm broad, ZMH 140694 View Materials ; paratypes: 3 ZMH 140695 View Materials , 3 in coll. Mabrouki, 3 in coll. Glöer.

Type locality: Morocco, Zerrouka , Ifran province, 33°32'35.7"N 5°05'42.7"W, 14.02.2020 leg GoogleMaps .

Etymology: Named after the type locality.

Habitat: Zerrouka is a rheocenous natural spring, partially modified, located at Ifran province at an altitude of 1613 m above sea level. The grain size of the bottom consists of stones, pebbles sand and sometimes silt and plant debris. The spring water feeds the Zerrouka lake, a small artificial fish pond classified as a site of biological and ecological interest (SIBE). It is located on the Zerrouka River, the main tributary of the Tizguite wadi. The dam is located about 300m from the source, so that the water from the spring flows directly in it. The reservoir is limited by a concrete wall, at least on the west bank. The aquatic and riparian vegetation at lake level is quite varied. The spring waters are used to supply the town of Ifrane with drinking water. The banks are subjected to a strong anthropic pressure, mainly by trampling cattle.

Description

Shell: The valavatoid shell has a very small spire. The body whorls is very prominent and the last whorl is descended. The first whorls are slightly convex with a clear suture. The aperture is nearly circular and the umbilicus is wide not covered by the last whorl. The outer line of the aperture is straight from lateral view. The peristome is sharp. The shell is 1.1 mm high and 1.5 mm in diameter.

Penis: The cylindric penis is long and slender, widened at the basis and tapered at the distal end with a pointed penis tip.

Operculum: The circular to ovate operculum is slightly concave, yellowish with an orange nucleus, and flat at the nucleus.

Distribution: Morocco, only known from the type locality.

Associated species: Physa acuta , Gyraulus sp.
