adding a box (domain) on a basemap map

Hi all

sorry for posting this question that might have been answered before, but I’m in the urgent need of finding a way to overlay a rectangular box on a basemap map (cylindrical projection) given the latitudes and longitudes of the domain. This is to delineate on a map the domain over which a index has been computed …

any quick answer welcome
