Sachatamia ilex has a deep leaf green body, with a light green or white throat and belly, and a distinct white lip stripe (Leenders 2001; Savage 2002). Occasionally, scattered white dots are present on the dorsum. This frog also has yellowish hands and feet (Leenders 2001). The bones are dark green, a characteristic shared with other centrolenid frogs and one genus of hylid frogs, Trachycephalus (treated under the name Phrynohyas in Savage 2002). Sachatamia ilex has a white, parietal peritoneal sheath covering its internal organs (Leenders 2001). The digestive tract itself is unpigmented (Savage 2002). The eyes are silver with black reticulations, and are positioned on top of the large semicircular head so that the eyes point directly forward (Leenders 2001). Nuptial pads are white (Savage 2002).
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Colombia, Costa Rica, Ecuador, Nicaragua, Panama
Life History, Abundance, Activity, and Special Behaviors
It is able to vary the intensity of its green coloration to match the substrate on which it is resting (Leenders 2001).
Males call from the upper side of leaves, usually with the head facing the tip of the leaf (Cisneros-Heredia and McDiarmid 2007). The call consists of a single high-pitched "click", repeated after intervals of several minutes (Savage 2002).
Females deposit black eggs on upper leaf surfaces overhanging a stream (Savage 2002).
