Cercosaura eigenmanni, known commonly as Eigenmann's prionodactylus, is a species of lizard in the family Gymnophthalmidae. The species is endemic to South America. C. eigenmanni was discovered in 1917 by L.E. Griffin. Adults of C. eigenmanni may attain a snout-to-vent length of about 4.5 cm (1.8 in).
The specific name, eigenmanni, is in honor of German-born American ichthyologist Carl H. Eigenmann. C. eigenmanni is found in Bolivia, Brazil (namely the states of Rondônia, Amazonas and Mato Grosso), and Peru. The preferred habitat of C. eigenmanni is forest at altitudes of 200–700 m (660–2,300 ft).
C. eigenmanni is oviparous. Doan, Tiffany M. (2003). "A new phylogenetic classification for the gymnophthalmid genera Cercosaura, Pantodactylus and Prionodactylus (Reptilia: Squamata)". Zoological Journal of the Linnean Society 137 (1): 101–115. (Cercosaura eigenmanni, new combination).

With luck
About 10% of wildlife watchers report an Eigenmann's Eyed Lizard sighting in Manu National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 49th most-seen of the 56 reptiles we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June and July
In those months about 20% of wildlife watchers report an Eigenmann's Eyed Lizard in Manu National Park on a given day, against under 5% in March–May and August–January, the lowest months. Those are among Manu National Park's driest months, with about 75 mm of rain a month against 290 mm in February.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Eigenmann's Eyed Lizard sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Manu National Park, in our data
Manu National Park is the only park on Wallace's Line with enough records to rate Eigenmann's Eyed Lizard sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Eigenmann's Eyed Lizard is recorded against all the reptiles logged in Manu National Park (6 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
