Nymphargus cristinae (Ruiz-Carranza & Lynch 1995)

A member of the ocellata group with the following combination of characters: 1) vomerine teeth present, 2) bones light green in life, 3) dorsal color in life is light green with many fine black specks, with a higher concentration on the limbs, 4) ulnar and tarsal folds absent, 5) humeral spine absent. Adults attain a medium size; females reach 29.7mm SVL and 26.0-31.1mm SVL in males. Head wider than body and wider than long (head width is 31.5-34.9% SVL); distance between nostril and anterior part of eye is 47.6-80.0% the diameter of the eye, diameter of the eye is 36.7-49.4% the length of the head. Hind limbs slim. Length of tibia is 52.9-64.4% SVL; when hind limb is adpressed anteriorly, the ankle reaches the anterior portion of the eye.

Known from the west side of the Cordillera Occidental of Colombia in the department of Antioquia at elevations between 2490m. Type locality is at the departamento of Antioquia, county of Urrao, vereda El Chuscal, quebradas Las Juntas and La Nevera, 2390-2490 m.

Adults found on vegetation approximately 1.50m in the border of breaks; eggs contain a brown embryo and yolk is cream colored.

Nymphargus cristinae is a species of frog in the family Centrolenidae, formerly placed in Cochranella. It is endemic to Colombia where it is only known near its type locality on the western slope of the Cordillera Occidental in Urrao, Antioquia. Its natural habitat is sub-Andean primary forest. It occurs on vegetation next to streams with canopy cover over the stream. Its conservation status is unclear but habitat degradation and loss caused by cattle raising, timber extraction, and cultivation of illegal crops are major threats.

Male Nymphargus cristinae grow to a snout–vent length of 26–31 mm (1.0–1.2 in). The dorsum is smooth to finally shagreen.
