In 3 days ~40% in a week ~70%
Cornufer punctatus, commonly known as the dotted wrinkled ground frog, is a species of frog in the family Ceratobatrachidae. It is endemic to Western New Guinea (Indonesia) and occurs in the Arfak and Wondiwoi Mountains on the New Guinea mainland well as on some adjacent islands (Batanta and Waigeo).
Adult males can grow to 51 mm (2.0 in) and adult females to 79 mm (3.1 in) in snout–vent length. Dorsal skin is relatively smooth, apart from the supratympanic fold. The fingers and the toes bear enlarged and grooved discs. The toes are one-third to one-half webbed. In preserved specimens, the dorsal surfaces are almost patternless dark brown. The facial area is darker brown and has broad, vertical bars on the upper lip that become less distinct on the lower lip. The sides of the body are lightly mottled and the groin is more heavily mottled. Much finer mottling is present on the posterior surfaces of the thighs, whereas the under sides of the tibias are heavily mottled. Other ventral surfaces are pale and nearly patternless, apart from the faint grayish mottling on the chin.

Possible
About 20% of wildlife watchers report a Dotted Wrinkled Ground Frog sighting in Raja Ampat on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 5th most-seen of the 5 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 50% of wildlife watchers report a Dotted Wrinkled Ground Frog in Raja Ampat on a given day, against under 5% in January–February and June–November, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Dotted Wrinkled Ground Frog sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Raja Ampat, in our data
Raja Ampat is the only park on Wallace's Line with enough records to rate Dotted Wrinkled Ground Frog sightings: about 20% of wildlife watchers there report one on a given day.
Same genus: Cornufer
The closest relatives of the Dotted Wrinkled Ground Frog that you can see in Raja Ampat (genus Cornufer) are Batanta Wrinkled Ground Frog (about 30%) and Papua Wrinkled Ground Frog (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dotted Wrinkled Ground Frog is recorded against all the amphibians logged in Raja Ampat (10 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.
