Description
Eleutherodactylus ronaldi is a member of the Eleutherodactylus auriculatus group (subgenus Eleutherodactylus). The digital discs are large. There is no webbing between the toes. The vomerine teeth, behind the choanae, are in a short and straight series (Schwartz 1960; Schwartz and Henderson 1985; Schwartz and Henderson 1991).

It is tan with a pale mid-dorsal hairline or a series of seven transverse bars. There is a faint interocular bar or triangle, and a dark brown face mask. The concealed surfaces of the hind limbs are dark brown. The venter is heavily stippled with brown, profusely spotted with white dots. The vocal sac and throat are pale yellow, stippled with brown. (Schwartz 1960; Schwartz and Henderson 1985; Schwartz and Henderson 1991).

Distribution and Habitat

Country distribution from AmphibiaWeb's database: Cuba

 

View distribution map using BerkeleyMapper.
This species is endemic to Cuba and it is found only in the Sierra Maestra and Sagua-Baracoa mountains, in eastern Cuba. It occurs in lowland and upland mesic broadleaf forests, and occasionally in pinewoods (Schwartz and Henderson 1991).

Life History, Abundance, Activity, and Special Behaviors
This frog is active at night. Males vocalize from shrubs and trees with dense foliage, up to 3 meters above the ground. Vocalization is a slow nonmetallic rapping composed of short “ticks” repeated many times in close, regular intervals (343-405 calls/minute). The dominant frequency is about 3.7-3.8 kHz (Schwartz 1960; Schwartz and Henderson 1991; Hedges et al. 1992).

Trends and Threats
This species is threatened by habitat destruction as a result of deforestation due to agriculture, woodcutting, disturbance from tourists, and infrastructure development for human settlement (Hedges and Diaz 2004).

Possible reasons for amphibian decline

General habitat alteration and loss
Habitat modification from deforestation, or logging related activities
Intensified agriculture or grazing
Urbanization
