Leptodactylus rhodomystax (common name: Loreto white-lipped frog, rose-lipped thin-toed frog) is a species of frog in the family Leptodactylidae. It is found in the Guianas (French Guiana, Guyana, and Suriname) through northern and central Brazil to Amazonian Bolivia, Colombia, Peru, and Ecuador, and possibly in Venezuela where most if not all records represent misidentifications of Leptodactylus riveroi.
Leptodactylus rhodomystax are small frogs: the two syntypes measured 25 mm (0.98 in) in snout–vent length. Leptodactylus rhodomystax in found in leaf-litter on forest floor and in swamps in tropical rainforest as well as on the edges of clearings and in more open areas in forest. It breeds in semi-permanent waterbodies. Leptodactylus rhodomystax is not very choosy about breeding sites and uses many types of temporary and semi-permanent pools. Males call from within holes in the ground. They seem not to form choruses, and usually only one or few males can be heard calling at a particular site. Eggs are laid in foam nests. Wikipedia →

Possible
About 20% of wildlife watchers report a Loreto White-lipped Frog sighting in Manu National Park on a given day, based on 59 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 16th most-seen of the 67 amphibians we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
February
In that month about 40% of wildlife watchers report a Loreto White-lipped Frog in Manu National Park on a given day, against under 5% in April and August–September, the lowest months. That is one of Manu National Park's wettest months, with about 290 mm of rain against 60 mm in August.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Loreto 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.
2nd of 2
Of the 2 parks where we can rate Loreto White-lipped Frog sightings, Manu National Park ranks 2nd at about 20%. The best odds are in Brownsberg Nature Park (Suriname, about 40%).
Same genus: Leptodactylus
The closest relatives of the Loreto White-lipped Frog that you can see in Manu National Park (genus Leptodactylus, Neotropical Grass Frogs) are Peru white-lipped frog (about 30%), Madre de Dios Thin-toed Frog (about 30%) and Smoky Jungle Frog (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Loreto White-lipped Frog is recorded against all the amphibians logged in Manu National Park (59 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.
