Barnard's Namib day gecko (Rhoptropus barnardi), also known commonly as Barnard's slender gecko, is a species of lizard in the family Gekkonidae. The species is native to southern Africa.

The preferred natural habitats of R. barnardi are savanna and rocky areas, at altitudes of 200–1,900 m (660–6,230 ft).[1]

Description

R. barnardi is the smallest species in its genus. Adults usually have a snout-to-vent length (SVL) of 3.0–4.5 cm (1.2–1.8 in). The maximum recorded SVL is 4.9 cm (1.9 in).[4]
