Leptodactylus guianensis, the Guiana thin-toed frog, is a species of frog in the family Leptodactylidae. It is endemic to Brazil, Colombia, French Guiana, Suriname, Guyana, and Venezuela. The adult male frog measures 79.5–109.5 mm in snout-vent length and the adult female frog 66.0–109.2 mm. Most individuals have a light-colored stripe on their lips. Many have a dark line under each eye.
Scientists named this frog guianaensis for its home on the Guiana Shield. Scientists have observed the frog in primary and secondary forest, near streams, and in some disturbed areas. Scientists believe it has some tolerance to anthropogenic disturbance. Scientists have observed the frog between 0 and 200 meters above sea level.
Scientists have seen this frog inside protected places. Scientists infer that this frog has young the way other frogs in Leptodactylus do: They deposit their eggs in nests made out of bubbles and the tadpoles develop in water. The IUCN classifies this frog as least concern of extinction. Wikipedia →

Likely
About 40% of wildlife watchers report a Guiana White-lipped Frog sighting in Brownsberg Nature Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 9th most-seen of the 18 amphibians we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
December
In that month about 60% of wildlife watchers report a Guiana White-lipped Frog in Brownsberg Nature Park on a given day, against about 10% in July and October, the lowest months. June and August–September have too few records to rate.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Guiana White-lipped Frog sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Brownsberg Nature Park, in our data
Brownsberg Nature Park is the only park on Wallace's Line with enough records to rate Guiana White-lipped Frog sightings: about 40% of wildlife watchers there report one on a given day.
Same genus: Leptodactylus
The closest relatives of the Guiana White-lipped Frog that you can see in Brownsberg Nature Park (genus Leptodactylus, Neotropical Grass Frogs) are Knudsen's Thin-toed Frog (about 50%), Loreto White-lipped Frog (about 40%) and Smoky Jungle Frog (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Guiana White-lipped Frog is recorded against all the amphibians logged in Brownsberg Nature Park (11 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.
