Description

Sachatamia ilex is a medium-sized frog, reaching up to 37 mm in length (Guyer and Donnelly 2005). It is commonly known as either the Ghost Glass Frog or the Limon Giant Glass Frog. Centrolene ilex can be up to twice the size of related species, making it the largest species of glass frog in Central America (Leenders 2001). 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). The pupils are horizontally elliptical (Leenders 2001). This frog also has prominent, protuberant nostrils located on a slightly elevated ridge on its head (Leenders 2001). The tympanum is round and indistinct (Savage 2002). Vomerine teeth are present in transverse rows between the choanae and are medially separated (Savage 2002). The toes are extensively webbed, in contrast to the fingers, where more extensive webbing is present only between the outer fingers (III-V). (Savage 2002). Finger and toe discs are present and truncate (Savage 2002). Males have a white nuptial pad on the dorsal and outer lateral surfaces at the base of the thumb (Savage 2002), and a humeral spine embedded within the arm musculature (i.e. non-protruding) and running approximately parallel to the humerus (Cisneros-Heredia and McDiarmid 2007).

Centrolene 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 (Leenders 2001). 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).
