Stygobiont and crenobiont minute gastropods representing the family Hydrobiidae (Caenogastropoda: Truncatelloidea), characterized by the valvatoid low-spired shell, were collected from one spring and four wells in Bouregreg region, NW Morocco. The shells were photographed and measured; shell biometry is illustrated with principal component analysis. Penes were illustrated and described. Mitochondrial cytochrome oxidase subunit 1 (COI) and 16S rRNA, as well as nuclear 18S rRNA sequences were used to infer the phylogeny. The snails represented two genera, both new to science. Their closest relatives were taxa from the Iberian Peninsula, the rough molecular estimate of the time of divergence between these Moroccan and Iberian genera coincided with the Pliocene Flooding, which restored the Strait of Gibraltar to connect the Mediterranean Basin with Atlantic Ocean.
从摩洛哥西北部布赖格赖格地区的一个泉和四口井中采集到了代表 Hydrobiidae 科（Caenogastropoda：Truncatelloidea）的有孔虫和淡水小型腹足动物，它们的特征是 valve 型低螺旋壳。对贝壳进行了拍照和测量；用主成分分析说明了贝壳生物测量学。描述并说明了阴茎。线粒体细胞色素氧化酶亚基 1（COI）和 16S rRNA 以及核 18S rRNA 序列用于推断系统发育。这些蜗牛代表了两个属，都是科学上新发现的。它们最亲近的亲戚是来自伊比利亚半岛的分类群，摩洛哥和伊比利亚属之间的粗略分子估计的分化时间与上新世洪水期相吻合，该洪水期恢复了直布罗陀海峡，将地中海盆地与大西洋连接起来。
