Ameerega hahneli is a species of frog in the family Dendrobatidae. It is found in the Amazonian lowlands of Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela, Guyana, French Guiana, and Suriname. It is named after Paul Hahnel, the collector of the type series.
Ameerega hahneli has been mixed with Ameerega picta, and also considered its synonym. It may represent several species; Ameerega altamazonica has already been split off from the former Ameerega hahneli. Males measure 17–19 mm (0.67–0.75 in) and females 19–22 mm (0.75–0.87 in) in snout–vent length. The back and limbs are finely granular and brown in colour, with or without black spots.

With luck
About 10% of wildlife watchers report a Pale-striped Poison Frog sighting in Tambopata National Reserve on a given day, based on 16 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 20th most-seen of the 44 amphibians we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
December
In that month about 30% of wildlife watchers report a Pale-striped Poison Frog in Tambopata National Reserve on a given day, against under 5% in January, April–May and October–November, the lowest months. That is one of Tambopata National Reserve's wettest months, with about 400 mm of rain against 45 mm in July.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Pale-striped Poison Frog sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
4th of 4
Of the 4 parks where we can rate Pale-striped Poison Frog sightings, Tambopata National Reserve ranks 4th at about 10%. The best odds are in Manu National Park (Peru, about 20%), Yasuní National Park (Ecuador, about 20%) and Cuyabeno Wildlife Reserve (Ecuador, about 20%).
GBIF citizen-science records
It is estimated from how often the Pale-striped Poison Frog is recorded against all the amphibians logged in Tambopata National Reserve (16 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.
