Origin of the species name:<\/h4>\n

\u00c9douard-Raoul Brygoo (later working at the Natural History Museum in Paris, France), Charles Pierre Blanc and Charles Antoine Domergue from the then Institut Pasteur in Antananarivo, Madagascar, dedicated the species to their colleague Jean-Louis Guillaumet. Among other things, the French Botanist dealt with the flora of Madagascar and wrote a number of publications about the island. He worked at the Natural History Museum in Paris.<\/p>\n

Distribution:<\/h4>\n

Calumma guillaumeti<\/em> is known from three different rainforests in the north and northeast of Madagascar. These are, on the one hand, the two national parks Marojejy and Anjanaharibe-Sud, and on the other hand, the Tsaratanana Mountains. All three places are poorly accessible and hardly visited by travelers. Calumma guillaumeti<\/em> can only be found from an average altitude of about 1300 m, in Marojejy we discovered it already a bit below that at about 1000 m above sea level between Camp Marojejya and Camp Simpona. A single juvenile we found even lower, namely in Camp Marojejya at about 775 m. But also the ascent there is incredibly strenuous, accordingly few photos of the species exist. In places, the species occurs in Marojejy sympatric with Calumma marojezense<\/em>.<\/p>\n

Venter coloration in Calumma guillaumeti<\/em><\/p><\/div>\n

Calumma guillaumeti<\/em> belongs to the small chameleon species. Both sexes reach up to 12 centimeters from nose to tail tip, most females remain slightly smaller at 10 cm. They carry neither throat nor ventral crest. Instead, a small dorsal crest is present in the anterior dorsal region, which distinguishes the species from Calumma marojezense<\/em> and Calumma vencesi.<\/em> The dorsal crest can even be used to distinguish juveniles of Calumma guillaumeti<\/em> and Calumma marojezense<\/em>. Both sexes are green colored. The males bear a yellow lateral stripe, above and below which several white dots are visible. They also have blue-rimmed eyelids and a line, also blue, extends from the tip of the nose on both sides of the head to the casque. In females, this stripe is simply dark in color. In addition, females either lack the lateral stripe altogether or it is only very delicately indicated. The number of white spots on the sides is variable. Calumma guillaumeti<\/em> bears a broad red ventral stripe flanked on both sides by a narrow white line.<\/p>\n
