Phyllodromus pulchellum Jiménez de la Espada, 1875 Colostethus pulchellum (Jiménez de la Espada, 1875) Colostethus tergogranularis Rivero, 1991 Colostethus taeniatus (Andersson, 1945) Hyloxalus pulchellus is a species of frog in the family Dendrobatidae from the Andes of northern Ecuador and southern Colombia.

[2][3][4][5] Hyloxalus pulchellus is found in the inter-Andean páramos of northern Ecuador and adjacent southern Colombia (Nariño, Cauca,[2][5][4] and Putumayo Departments[4]) and on the eastern slopes of the Andes from southern Colombia south in Ecuador to the headwaters of the Pastaza River.

[5] The frog's range includes many protected parks: Parque Nacional Sumaco Napo-Galeras, Reserva Ecológica Antisana, Parque Nacional Llanganates, Reserva Ecológica Cayambe-Coca, Bosque Protector Sierra Azul, and more in Colombia.

It has an oblique lateral stripe extending to eye, cream with iridescent golden tint in colour and sometimes edged with brown or black.

It suffers from habitat loss associated with the construction of human habitation and roads, logging, and the introduction of non-native predatory fish.
