Islamia coronadoi is endemic to Spain, where it was found "in the outskirts of Madrid, or at least some of the springs or streams in the province of Castilla la Nueva " (Bourguignat 1870). During the successive sampling of recent years it has not been rediscovered in Madrid, so presumably has been extinguished at these sites.
This species may well be extinct, as recent surveys have failed to find it and it was only known from the type locality. However the type locality was not well defined, and so may not have been relocated. The species may well qualify as Critically Endangered, Possibly Extinct (CR A2c, PE), but as the species was not treated in the Spanish Red List, it is maintained as Data Deficient (DD), pending clarification of the survey information.
