Meristogenys jerboa is a species of frog in the family Ranidae. It is endemic to western Sarawak in Borneo (East Malaysia). Common names western torrent frog, Matang torrent frog, and Gunther's Borneo frog have been coined for it. Many cryptic species have been separated from this species. Based on mitochondrial DNA, current "true" Meristogenys jerboa still includes two major lineages. However, because the lineages occur in sympatry and do not differ in morphology, Shimada and colleagues elected to treat them as intraspecific variants.
Females can grow to 82 mm (3.2 in) in snout–vent length, males are considerable smaller. In a sample of 32 males and 6 females representing several populations, adult males measured 34–41 mm (1.3–1.6 in) and adult females 61–65 mm (2.4–2.6 in) in snout–vent length. The snout is protruding in vertical view. Males have larger tympanum compared to females. Males have a slender body, whereas females are slightly more stocky. The toes are webbed. A black marking surrounds the eye and the tympanum and extends to the flank. The iris is bronze in the upper third and coppery in the lower parts.
The tadpoles have a large suctorial disk. They are...

Likely
About 40% of wildlife watchers report a Western Torrent Frog sighting in Kubah National Park on a given day, based on 105 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 22nd most-seen of the 41 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.
June and September–November
In those months about 50% of wildlife watchers report a Western Torrent Frog in Kubah National Park on a given day, against under 5% in December and January, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Western Torrent Frog sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Kubah National Park, in our data
Kubah National Park is the only park on Wallace's Line with enough records to rate Western Torrent Frog sightings: about 40% of wildlife watchers there report one on a given day.
Same family: Ranidae
The closest relatives of the Western Torrent Frog that you can see in Kubah National Park (family Ranidae, Typical Frogs) are Copper-cheeked Frog (about 80%), Black-spotted Rock Skipper (about 70%) and Brown Marsh Frog (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Western Torrent Frog is recorded against all the amphibians logged in Kubah National Park (105 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.
