Congolacerta


Congolacerta is a genus of equatorial African lacertids of the family Lacertidae. Species of this genus are distributed in western East Africa.

Etymology

The name Congolacerta is a combination of "Congo" and "lacerta". The common name is Congo Lizard.

Distribution

Congolacerta vauereselli occurs from the Lendu Plateau along the Albertine Rift and its foothills through southwestern Uganda, Rwanda, and northwestern Tanzania as far south as the Kabobo Plateau at the border of South Kivu and Katanga Provinces, Democratic Republic of Congo.
C. asukului is known from only four localities from a small area at the highest elevations of the Itombwe Plateau/South Kivu/Democratic Republic of Congo.

Habitat and natural history

Congolacerta are diurnal lacertid lizards which are good climbers on standing and fallen timber and rocky walls and presumably lay eggs. They emerge to bask as the morning warms up, and will then hunt for small arthropods.
Congolacerta vauereselli can be found in clearings and openings within Guineo-Congolian forests from 1000–2675 m altitude. In Parc National des Volcans/Rwanda this species lives only on the artificial volcanic rock wall intended to keep buffalo inside the park boundary. C. vauereselli is sympatric in this region with Adolfus jacksoni and were found basking within 3 m of each other on the wall. Adolfus jacksoni appeared to be more common than C. vauereselli. Spawls et al. mentions that C. vauereselli is a true forest lizard, but it was never encountered in true forest or any other closed canopy habitat.
Congolacerta asukului occurs in high-elevation grasslands often near rocky outcrops of the Itombwe Plateau in the Albertine Rift Montane Forest ecoregion. They inhabit high-elevation meadows that are common amongst rivers, swamps, and subalpine scrub forests, which are dominated by tree heathers and other Ericaceae. Individuals were observed basking on rocks, and they retreat to small burrows amongst tussocks of grass.
