The merchant gecko (Hemidactylus mercatorius) is a species of gecko. There has been confusion between it and Hemidactylus mabouia, making it difficult to establish the ranges of the species. While the Reptile Database gives Hemidactylus mercatorius a wide distribution in eastern Africa, the IUCN restricts its native distribution to Madagascar and some other islands in the Indian Ocean (the Comoros, Seychelles, Mayotte).

Possible
About 30% of wildlife watchers report a Farquhar Half-toed Gecko sighting in Ranomafana National Park on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 20th most-seen of the 29 reptiles we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
October
In that month about 50% of wildlife watchers report a Farquhar Half-toed Gecko in Ranomafana National Park on a given day, against under 5% in April–July and December, the lowest months. That is one of Ranomafana National Park's driest months, with about 130 mm of rain against 450 mm in January.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most Farquhar Half-toed Gecko sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Only Ranomafana National Park, in our data
Ranomafana National Park is the only park on Wallace's Line with enough records to rate Farquhar Half-toed Gecko sightings: about 30% of wildlife watchers there report one on a given day.
Same family: Gekkonidae
The closest relatives of the Farquhar Half-toed Gecko that you can see in Ranomafana National Park (family Gekkonidae, Typical Geckos) are Satanic Leaf-tailed Gecko (about 80%), Peacock Day Gecko (about 80%) and Striped Day Gecko (about 70%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Farquhar Half-toed Gecko is recorded against all the reptiles logged in Ranomafana National Park (15 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.
