These planarian species have bilateral symmetry with a soft, leaf-shaped and ciliated body of 3 to 15 mm length and can grow up to 30 cm.

Its head is spade-shaped with two eyes which help him in running away from light and a brain made of ganglion cells. The mouth is present on the ventral (lower) side of the body towards the tail which is pointed.
