Two new genera and species of the valvatiform hydrobiid snails (Caenogastropoda: Truncatelloidea: Hydrobiidae) from Morocco.
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.
期刊介绍：
Zootaxa is a peer-reviewed international journal for rapid publication of high quality papers on any aspect of systematic zoology, with a preference for large taxonomic works such as monographs and revisions. Zootaxa considers papers on all animal taxa, both living and fossil, and especially encourages descriptions of new taxa. All types of taxonomic papers are considered, including theories and methods of systematics and phylogeny, taxonomic monographs, revisions and reviews, catalogues/checklists, biographies and bibliographies, identification guides, analysis of characters, phylogenetic relationships and zoogeographical patterns of distribution, descriptions of taxa, and nomenclature. Open access publishing option is strongly encouraged for authors with research grants and other funds. For those without grants/funds, all accepted manuscripts will be published but access is secured for subscribers only.
