Catharanthus scitulus is a species of flowering plant in the family Apocynaceae. It is endemic to Madagascar, where it is found in the sub-arid south in low-lying, sandy soil. Similar to C. lanceus, the plant branches out more than the other species. Its stems spread, with pseudo-dichotomous branching, coming together to form a rosette at each node. The corolla is pink or violet at the lobes.
