Dorsal coloration varies extensively in this species. Individuals may be yellow, pinkish, brownish, greyish, or dark green. All individuals have distinct darker spots on the dorsal surface; in some individuals the patterning extends into dark crossbars. No barring is present on the upper surfaces of the thighs.


The ventral surface is white, but may be contain some dark pigmentation.

Pristimantis caryophyllaceus Ventral 1

Concealed surfaces

The coloration of the rear surfaces of the thigh and the groin are pale yellow and do not contrast with the coloration of the rest of the body.


Eye color varies from yellow to grey to bright red.


The heels have well-developed pointy tubercles.

Life history


Clutches of eggs are laid on leaves in the forest (Myers 1969). Eggs turn white shortly after being laid (Savage 2002).

Ecology behavior and evolution


A variety of small arthropods, including dipterans and orthopterans but not ants (Lieberman 1986).


May be found on low vegetation in the forest (Savage 2002).

Behavior and communication

Females brood their eggs, covering them with their bodies (Myers 1969).


2N = 32 (DeWeese 1976)
