Sphingonotus nodulosus is a restricted range species, known from only four localities in southern Spain and Portugal. One of these localities is severely affected by an ongoing touristic project including a new hotel and golf course. Its known area of occupancy (AOO) is 16 km² with a maximum estimate of 200 km². The population is severely fragmented and there is a continuing decline in the extent of occurrence, area of occupancy, number of subpopulations, extent and quality of habitat as well as the number of mature individuals. The species is therefore assessed as Endangered (EN).
