Small, elongated fish of the family Lebiasinidae, reaching 16 cm. Its most distinctive feature is the two dark spots on its body, which give it its name. It can be confused with Lebiasina astrigata, which lives in northern Ecuador in the same region and also reaches 16 cm, but has a series of round spots on the flank instead of two.
