Namaqua chameleons discovered in Namibe (Angola)

Namaqua chameleons discovered in Namibe (Angola)

by Alex Negro Verbreitung Science

Western Angola has increasingly become the focus of herpetologists in recent years. However, the reptile population of the Iona National Park on the border with Namibia still raises some questions. Whilst searching for the dwarf puff adder Bitis peringueyi, an international research team also found Chamaeleo namaquensis. The survey of reptile populations was carried out in the coastal area, in the sand sea and in the shifting sand dunes of the gravel plains.

A total of 27 reptile species were discovered – although the dwarf puff adder was not among them. Chamaeleo namaquensis was found along the EN100 road about 50 kilometres south of Moçamedes. A second site was found around 10 km north of Salondjmba, the entrance to the Iona National Park in Ponta Albina.

The flap-necked chameleon on Serra da Neve (Angola)

The Serra da Neve inselberg is located in the province of Namibe in south-west Angola on the south-western edge of Africa. At 2489 metres above sea level, it is the second highest mountain in the country. The isolated location in the middle of savannahs makes the inselberg a refuge for biodiversity, but this has so far been poorly researched concerning herps. Scientists from the USA, Portugal and Germany have recently carried out a first survey study to inventory the amphibians and reptiles of the Serra da Neve.

Three expeditions have been carried out since 2016, each lasting a few days. Eight areas were selected to search for animals, including rocky areas as well as forest, open grassland and various altitudes. Pitfall traps, snares, rubber bands and manual searches by day and night were used to find the animals. The individuals found were all killed and prepared for storage and further examination in the museum.

A total of 59 species of reptiles and amphibians were found on the inselberg. Chamaeleo dilepis was found exclusively around the village of Catchi, located at 1590 metres. The village is surrounded by granite rocks and the Miombo forest area, which is dominated by Brachystegia and Julbernardia trees. The flat parts of the plateau surrounding the village are largely deforested. The land is used for grazing cattle or for growing cereals and maize. However, the steep slopes around the village are still forested. A small river also runs through the plateau.
