A new species of Tropidophis is described from the province of Sancti Spiri
tus in central Cuba. This small, spotted, gracile species differs from all
others in the genus by a combination of scalation, head shape, and color pa
ttern. It is tentatively placed in the semicinctus group of gracile, boldly
spotted species, but it does not appear to be closely related to any speci
es in the genus.
