Pseudophilautus stictomerus (common name: orange-canthal shrub frog) is a species of frog in the family Rhacophoridae. It is endemic to Sri Lanka. It was first described by Albert Günther (as Ixalus stictomerus) based on a single individual collected by Colonel Richard Henry Beddome from 'Ceylon'.
Male Pseudophilautus stictomerus measure about 23 mm (0.91 in) in snout-vent length of and females 25–36 mm (0.98–1.42 in). They have an elongated body with an obtusely pointed snout. The dorsum is dark brown. There is a narrow yellow stripe on mid-dorsum from tip of snout to vent. There are also bright orange stripes running along the canthal edges, edges of upper eyelids, and supratympanic folds.
Pseudophilautus stictomerus is a low-country wetzone species from south-western Sri Lanka. It is a habitat generalist found in both open (anthropogenic) and closed canopy habitats at elevations of 60–515 m (197–1,690 ft) above sea level. They are commonly found on shrubs some 1 metre above ground. The species is potentially threatened by agro-chemical pollution and habitat loss and alteration. Wikipedia →

Possible
About 20% of wildlife watchers report an Orange-canthal Shrub Frog sighting in Sinharaja Forest Reserve on a given day, based on 23 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 16th most-seen of the 25 amphibians we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
August
In that month about 40% of wildlife watchers report an Orange-canthal Shrub Frog in Sinharaja Forest Reserve on a given day, against under 5% in September to November, the lowest months.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Orange-canthal Shrub Frog sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Sinharaja Forest Reserve, in our data
Sinharaja Forest Reserve is the only park on Wallace's Line with enough records to rate Orange-canthal Shrub Frog sightings: about 20% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Orange-canthal Shrub Frog is recorded against all the amphibians logged in Sinharaja Forest Reserve (23 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.
