Members of this genus are widespread from Ryukyu Is. in Japan, and throughout South-east Asia, (China, Sumatra, Java, Bali, Borneo, India and Sri Lanka).
In 2021, nine species of Microhyla were moved to Nanohyla on the basis of morphological and phylogenetic differences. Microhyla pulverata was found to be a junior synonym of Nanohyla marmorata based on phylogenetic evidence.
According to Seshadri et al. (2016), this genus can be diagnosed using the following set of criteria: Adult frogs are of small size; pupil circular; skin on dorsum smooth; lateral side of body with markings from back of eye to vent; supratympanic fold present in adults; paratoid glands are absent, fingers without webbing, finger tips may or may not be dilated; oval tongue, its margin is entire and free at the base; the diameter of eye is smaller than snout; a thin layer of skin hides the tympanum; tubercles on hand distinct; distinct oval shaped inner metatarsal tubercle and rounded outer metatarsal tubercle; webbing in...

Likely
About 40% of wildlife watchers report a Bornean Narrow-mouthed Frog sighting in Kubah National Park on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 26th most-seen of the 41 amphibians we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
January and November
In those months about 50% of wildlife watchers report a Bornean Narrow-mouthed Frog in Kubah National Park on a given day, against under 5% in July, the lowest month.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Bornean Narrow-mouthed 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.
Yes
Of the 2 parks where we can rate Bornean Narrow-mouthed Frog sightings, Kubah National Park has the highest daily chance: about 40%. Next come Kinabatangan Wildlife Sanctuary (Malaysia, about 10%).
GBIF citizen-science records
It is estimated from how often the Bornean Narrow-mouthed Frog is recorded against all the amphibians logged in Kubah National Park (17 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.
