Pseudophilautus schneideri (Schneider's shrub frog) is a species of frogs in the family Rhacophoridae, endemic to Sri Lanka. People have seen it in only a few places: Kudawa, Pituwela, and Kanneliya. People have seen it between 1100 and 1400 meters above sea level.
The adult male frog measures 19.9 – 22.8 mm in snout-vent length and the adult female frog about 20.7 mm. The skin on the top of the frog's head is light brown and the skin on the sides of the frog's head is darker brown. The skin near the tympanum and intraorbital area is black in color. The skin of dorsum is dark brown in color with black spots and dark brown spots. The flanks are light brown with dark brown spots. The inguinal area is yellow-brown with dark brown spots. The sides of the legs are light brown with dark brown spots. All toes are light yellow-brown with some dark brown. The belly, chest, and throat are pale brown in color.
Scientists named this frog after herpetologist Professor Christopher J. Schneider of Boston University. Scientists attribute the decline in this frog's population to habitat loss associated with agriculture, grazing, and logging.

Possible
About 30% of wildlife watchers report a Schneider's shrub frog sighting in Sinharaja Forest Reserve on a given day, based on 40 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 7th most-seen of the 25 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.
March and August
In those months about 40% of wildlife watchers report a Schneider's shrub frog in Sinharaja Forest Reserve on a given day, against under 5% in October and November, the lowest months.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most Schneider's shrub frog sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only Sinharaja Forest Reserve, in our data
Sinharaja Forest Reserve is the only park on Wallace's Line with enough records to rate Schneider's shrub frog sightings: about 30% of wildlife watchers there report one on a given day.
Same genus: Pseudophilautus
The closest relatives of the Schneider's shrub frog that you can see in Sinharaja Forest Reserve (genus Pseudophilautus, Shrub Frogs) are Common Shrub Frog (about 30%), Sharp-snouted Shrub Frog (about 30%) and Hollow-snouted Shrub Frog (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Schneider's shrub frog is recorded against all the amphibians logged in Sinharaja Forest Reserve (40 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.
