Two new species of valvatoid hydrobiids are reported from southern and eastern Spain that showed notable similarities with Horatia Bourguignat, 1887 Bourguignat, J. R. 1887. Étude sur les noms génériques des petites paludinidées a opercule spirescent suivie de la description du nouveau genre Horatia., 56Paris: Tremblay V. Société Malacologique de France. 1 plate EX[Crossref] , [Google Scholar] species. However, a conchological redescription of Horatia klecakiana Bourguignat, 1887 Bourguignat, J. R. 1887. Étude sur les noms génériques des petites paludinidées a opercule spirescent suivie de la description du nouveau genre Horatia., 56Paris: Tremblay V. Société Malacologique de France. 1 plate EX[Crossref] , [Google Scholar], the type species of this Balkan genus, and the study of new characters for the Iberian species suggest differences between the Balkan and the Iberian groups of species. These differences and the large geographical separation between the Balkan and the Iberian populations for species with poor dispersal capacity lead us to introduce a new generic taxon, Iberhoratia Arconada and Ramos (this paper), to include the two new species. In the Iberian Peninsula, another two species have been described in Horatia, H. (?) sturmi (Rosenhauer, 1856) and H. gatoa Boeters, 1980 Boeters, H. D. 1980. Unbekannte westeuropäische Prosobranchia, 3.. Basteria, 44: 61–64. [Google Scholar]. The first was recently moved to a new genus, Boetersiella Arconada and Ramos, 2001 Arconada, B. and Ramos, M. A. 2001. New data on Hydrobiidae systematics: two new genera from the Iberian Peninsula.. Journal of Natural History, 35: 949–984. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar], while the second is here assigned to Iberhoratia. The introduction of a new genus for the Iberian Peninsula is another indication of the richness and endemic diversity of the Hydrobiidae in this region.
