This species is is known only from the northern Cordillera Central of the Colombian Andes at 1800-2000 masl, in the department of Caldas, Municipality of Samaná. It can be found within the Parque Nacional Natural Selva de Florencia, on the eastern flank of the cordillera Central, ca 5 30' N, 75 5' W (Rueda-Almonacid et al., 2006).
Habitat and Ecology
Ranitomeya daleswansoni lives in the wettest areas of the understory of both primary and secondary montane forests. Animals are concentrated in areas with moderate leaf litter, high humidity and abundant refuges or holes in the ground. It is sympatric with Ranitomeya opisthomelas at around 1800m, but replaces it above this elevation. The larvae have been found in bromeliads (Rueda-Almonacid et al., 2006), while eggs are laid in the leaf litter. Reproduction is possibly continuous throughout the year, based on the examination of gonads in preserved specimens and on the presence of tadpoles at any time of the year. Clutch size is unknown. Ranitomeya daleswansoni can inhabit secondary or selectively logged forests insofar as it is adjacent or in the vicinity of primary forests (J.V. Rueda-Almonacid, pers. comm.).
It is a relatively common species in forested habitats within its distribution range (Rueda-Almonacid et al., 2006).
Deforestation for the purposes of wood collection is present in this species' geographic area. In addition, there appear to be bromeliad collection and illegal trade activities (J.V. Rueda-Almonacid, pers. comm.).
It occurs within the Parque Nacional Natural Selva de Florencia.
Ranitomeya daleswansoni can be recognised by a combination of morphological features and colour patterns (Rueda-Almonacid et al., 2006).
