Description:
From now on, the genus Bragasellus Henry & Magniez, 1968 includes 2 oculated and 17 stygobiotic species. As a natural and monophyletic taxonomic unit, we consider it a good genus.\nIts original area corresponds to the north-west quarter of the Iberian Peninsula. Secondarily, this area has extended eastward, using mainly the alluvial channels of hydrographic systems (R\xc3\xados Douro + Ebro and tributaries), finally reaching the underground waters of several Mediterranean rivers.\nThis active expansion is exclusively due to the migration of two stygobiotic sibling species: B. lagari Henry & Magniez, 1973 towards the high basin of the R\xc3\xado Tajo, then downstream to the basins of the R\xc3\xados Jucar and Turia (Prov. Valencia); and B. lagarioides n. sp., downstream the R\xc3\xado Ebro basin, towards the R\xc3\xado Gaya basin (Prov. Tarragona).
