Adult: Species description based on Savage (2002). Small, delicate frog with large eyes and a rounded snout. Males to 29 mm, females to 32 mm. Dorsal: Dorsal surface bluish-green and granular with small white or yellowish spots. Ventral: The ventral surface is white. The heart is covered, but the digestive tract is clearly visible. Distinguishing characteristics: Sachatamia albomaculata has a white line along the upper lip and along the outer arm. Eye: Iris golden-gray with black reticulations. Pupil horizontal. Extremities: The feet are moderately webbed.
Breeding season: This species breeds throughout the rainy season (Ibanez et al 1999, Puschendorf et al 2004). In Costa Rica, males aggregate and concentrate calling activity near waterfalls (Puschendorf et al 2004). Presumably, the spray from waterfalls allows them to prolong breeding into the early part of the dry season (Puschendorf et al 2004). Egg: Newly laid eggs are black and white (Savage 2002). Tadpole: The tadpole of Sachatamia albomaculata is undescribed but Lips and Savage (1996) suggest some characteristics that it is likely to have based on the features of other Centrolenid tadpoles. In particular, they are likely to have 3 lower teethrows and 1 full and 1 partial (limited to a short segment on either side) upper toothrow (Lips and Savage 1996). Centrolenid tadpoles are fossorial, living in the low-oxygen environment under mud and leaf litter in stream bottoms (McDiarmid and Altig 1999).
Habitat: Lowland and premontane forest to 1500 m elevation. Ecology: Populations of Sachatamia albomaculata are beginning to decline east of the Panama Canal due to the invasion of chytrid fungus (Woodhams et al 2008). Call: A single dik (Savage 2002). Karyotype: 2N = 20 (Duellman 1967)
Diagnostic description: The back has many well-demarcated light spots. Usually without enlarged parotid glands, but if present. Head lacking ridges. No dorsal fold in the head. No fleshy fold on the roof of the mouth. The belly is transparent in living specimens, which will allow the internal organs. Green Bones in live specimens.
Lacking a tarsal tubercle conspicuous, and the leg lacks tarsal fold. They have legs with five toes. No two elongated inner tubers, such as shovels, with a free margin. Without a pair of fleshy protrusions on the dorsal terminal finger region. They have a small digital groove, which separates the upper surface of the finger and bearing, at least in the two outer fingers and toes of the foot. With a fleshy fold well defined in the posterior margin of the forearm. Ventral disk lacks. The fingers are usually membranes. Cartilage interlayer present between the last phalanges of the fingers. The talus and calcaneus are fused. The terminals are fastened straight or T or Y have vomerine teeth. The snout between upright and rounded profile.
Food: They feed on small insects like flies and crickets.
Distribution in Costa Rica: In the wetlands, low and medium, and the Atlantic slope of the center and south of the Pacific slope, between 20 and 1,500 m. Lift (Savage 2002).
Distribution outside Costa Rica: It is located on the Caribbean slope of Costa Rica and the Pacific slope of Costa Rica and Panama to western Colombia.
