Abstract
A new species, Cuscuta cotijana, is described and illustrated from the Trans-Mexican Volcanic Belt in northwestern Michoacán, Mexico. The species is most closely related to Cuscuta jalapensis, C. mitriformis, C. rugosiceps and C. lindsayi, from which it differs by the large spur-like projections on the outer calyx lobes and the ovoid to conical capsule with a small intrastylar aperture.
