First description:

Brygoo & Domergue, 1969

Origin of the species’ name:

Édouard-Raoul Brygoo (later working at the Natural History Museum in Paris, France) and Charles Antoine Domergue of the then Institut Pasteur in Antananarivo, Madagascar, named the species after the botanist Jean Thiel. Thiel had found most of the animals of the species in 1968 and brought them to Antananarivo.

Distribution:

Brookesia thieli is found in central-eastern Madagascar in the areas of Moramanga, Andasibe, Vohimana, and Anjozorobe. There is also a further population higher up in the north near Masoala. So far we have been able to find the animals in the rainforest of Andasibe-Mantadia National Park, Ranomafa National Park, and Anjozorobe.

Appearance & size:

These leaf chameleons reach a maximum size of 73 mm. At the back, a row of eleven spinous processes runs on both sides, which continues over the tail. Both sexes have tubercles at the chin. The basic color of these animals are different shades of brown, most individuals have a light-colored back and darker sides and belly. The projection above the nose is well developed.

We have collected the data given above over several years with thermometers and hygrometers at the finding places of the chameleons. "Average temperature" means that values of a whole month have been calculated to one average value per month. For example all measured minimum temperature values of February have been calculated to one average minimum temperature for February. In plain language, this means single peak values of a day may be a little higher or lower than the average minimum and maximum temperatures. It is possible that a location has an average maximum temperature of 29°C, but one day during that month it had 33°C or even 35°C there.

The region around Andasibe with the belonging forests Mantadia and Analamazaotra is located in Madagascar's eastern highlands at elevations between 900 and 1250 m above sea level. Thus temperatures sometimes reach temperatures above 25°C, but thermometers rarely climbs above 30°C or only in sunny places. At night, temperatures always drop to 10° to 15°C.

Humidity in Andasibe's rainforest is high all year long. During rainy season, it rains intensively every day, sometimes rain even lasts for days. But also dry season does not differ much besides the fact of cooler temperatures. It still rains at least every other day, in most years more often. Rain, humidity and temperature drop at night are the key features of the region around Andasibe.

We have measured UVB data with a Solarmeter 6.5 in spring (March, April) at the peak of activity of chameleons in Madagascar. We always measured the values that a chameleon could maximally reach in its habitat.

Unfortunately, we have no ground temperatures for the region of Andasibe available yet.

Habitat:

The following photos show extracts from the habitat of Brookesia thieli in Andasibe and finding sites in Anjozorobe. The species hides well in the undergrowth, which consists of many small plants, loose branches, and few fallen tree trunks. The animals live on the thick layer of leaves and on very low branches and branches of bushes. In Anjozorobe, Brookesia thieli lives mainly in microhabitats heavily overgrown with ferns.
