Minervarya keralensis (common names: verrucose frog, Kerala wart(y) frog, or Dubois' hill frog) is a species of frog from India. Originally described by Albert Günther in 1876, its present-day specific epithet, keralensis, meaning "of Kerala", was introduced as replacement name by Alain Dubois in 1981.
This species has vomerine teeth in two strong oblique series starting from the inner anterior corners of the choanae. The head is moderately sized with the snout appearing pointed. The inter-orbital space is two-thirds the width of the upper eyelid. The tympanum is distinct and is about three-quarters the diameter of the eye. Fingers are moderate, obtuse and the first extends beyond the second. Toes are moderately well developed and nearly entirely webbed. Sub-articular tubercles are prominent and the inner metatarsal tubercle is oval, compressed and less than half as long as the first toe. It also has a small rounded outer metatarsal tubercle. When the hind leg is pulled forward, the tibio-tarsal articulation reaches the tip of the snout. Upper parts have numerous very prominent warts and short glandular folds.

Likely
About 40% of wildlife watchers report a Kerala Warty Frog sighting in Periyar National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the most-seen of the 5 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.
October
In that month about 70% of wildlife watchers report a Kerala Warty Frog in Periyar National Park on a given day, against under 5% in February and December, the lowest months. That is one of Periyar National Park's wettest months, with about 330 mm of rain against 15 mm in February.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Kerala Warty Frog 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 Periyar National Park, in our data
Periyar National Park is the only park on Wallace's Line with enough records to rate Kerala Warty Frog sightings: about 40% of wildlife watchers there report one on a given day.
Same order: Anura
The closest relatives of the Kerala Warty Frog that you can see in Periyar National Park (order Anura, Frogs and Toads) are Bicolored Frog (about 40%), Ponmudi Bush Frog (about 30%) and Common Indian Toad (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Kerala Warty Frog is recorded against all the amphibians logged in Periyar National Park (12 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.
