The specific name, beccarii, is in honor of Italian botanist Odoardo Beccari. On the island of Borneo, T. beccarii is found in Brunei, northern Kalimantan (Indonesia), Sabah, and Sarawak (Malaysia). The preferred natural habitats of T. beccarii are forest and freshwater wetlands, at altitudes from sea level to 1,000 m (3,300 ft).
Dorsally, T. beccarii is reddish brown, with dark brown crossbands. The flanks have whitish spots. Ventrally, it is yellowish. T. beccarii may attain a snout to vent length (SVL) of 9.8 cm (3.9 in). The largest specimen measured by Boulenger had an SVL of 8 cm (3.1 in), and a tail length of 10.6 cm (4.2 in).
T. beccarii preys upon water insects. T. beccarii is viviparous. Average litter size is four. Goldberg SR (2017). "Reproduction in Beccari's Keeled Skinks, Tropidophorus beccarii (Squamata: Scincidae... Wikipedia →

With luck
About 10% of wildlife watchers report a Beccari's Keeled Skink sighting in Kinabalu Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 56th most-seen of the 69 reptiles we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
September
In that month about 30% of wildlife watchers report a Beccari's Keeled Skink in Kinabalu Park on a given day, against under 5% in February–March, May–June and October–December, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Beccari's Keeled Skink sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Kinabalu Park, in our data
Kinabalu Park is the only park on Wallace's Line with enough records to rate Beccari's Keeled Skink sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Scincidae
The closest relatives of the Beccari's Keeled Skink that you can see in Kinabalu Park (family Scincidae, Skinks) are Borneo Skink (about 30%), Rough Mabuya (about 30%) and Sabah Slender Skink (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Beccari's Keeled Skink is recorded against all the reptiles logged in Kinabalu Park (6 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.
