Gonocephalus klossi, also known commonly as Kloss's forest dragon or Kloss' forest dragon, is a species of lizard in the family Agamidae. The species is endemic to Sumatra, Indonesia. The specific name, klossi, is in honor of English zoologist Cecil Boden Kloss.
G. klossi is found in western Sumatra, where it has been recorded from the provinces of Bengkulu and Jambi. The preferred natural habitat of G. klossi is forest, at altitudes of 50–1,800 m (160–5,910 ft), but it may also be found in disturbed areas.
G. klossi is arboreal and diurnal. G. klossi is oviparous. Boulenger GA (1920). "Results of an Expedition to Korinchi Peak 12,400 ft, Sumatra. III.

Likely
About 40% of wildlife watchers report a Kloss' Forest Dragon sighting in Kerinci Seblat National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
July
In that month about 60% of wildlife watchers report a Kloss' Forest Dragon in Kerinci Seblat National Park on a given day, against about 10% in February–June and October–November, the lowest months. That is one of Kerinci Seblat National Park's driest months, with about 140 mm of rain against 310 mm in March.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Kloss' Forest Dragon sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Only Kerinci Seblat National Park, in our data
Kerinci Seblat National Park is the only park on Wallace's Line with enough records to rate Kloss' Forest Dragon sightings: about 40% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Kloss' Forest Dragon is recorded against all the reptiles logged in Kerinci Seblat National Park (10 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.
