| Sumario: | [EN] The knowledge about geographic distribution of species and intraspecific lineages, and the populations and metapopulations dynamic is essential to stablish conservation bases in many organisms. In recent years, the insight about anostraceans local distribution in the Iberian Peninsula has been greatly increased through taxonomic surveys in temporary natural and artificial aquatic environments. In this work, we review and update the Anostraca species distribution in centre and western areas of Iberian Peninsula, incorporating 157 new records deriving from surveys performed between 2015 and 2019. There are 5 species of anostraceans, of which the Iberian endemism Tanymastigites lusitanica is the one with less known populations, limited to a few localities in the Portuguese region of Alentejo. On the other hand, the new records provided for Branchipus schaefferi, Chirocephalus diaphanus and Tanymastix stagnalis increase their currently known occurrence area in the septentrional half of the Iberian Peninsula, especially in river Duero basin. First records of Branchipus cortesi are provided for Ciudad Real and Toledo provinces, the latter being the septentrional limit recognized for this species. Derived from the last phylogeographic studies in different species of Anostraca, which revealed the occurrence of geographically structured intraspecific lineages, it is demonstrated the need of conservation efforts focused on the identification and delimitation of evolutionary independent populations to be treated as conservation units. In the same way, we highlight the interest of the group for conservation purposes, and the pressures to which it is subjected, and suggest the necessary encourage of land traditional uses development that allow ground heterogeneity and promote the formation of ephemeral and unstable ponds |
