Sepsina bayonii, also known commonly as Bayon's skink, is a species of lizard in the family Scincidae. The species is native to Central Africa and Southern Africa.
The specific name, bayonii, is in honor of Francisco Antonio Pinheiro Bayão, a Portuguese planter in Angola, who collected the holotype.[1]
S. bayonii is found in Angola and in the Democratic Republic of the Congo.
The preferred natural habitat of S. bayonii is savanna, at altitudes from sea level to 500m (1,600feet).
S. bayonii has no front legs. Each back leg is very small, tapering, and ends in a claw. The largest specimen measured by Boulenger had a snout-to-vent length (SVL) of 7.1cm (02.8inches), a tail length of 4.4cm (01.7inches), and a hind leg length of 0.4cm (00.2inches).
S. bayonii burrows in leaf litter and loose sandy soil.
S. bayonii is viviparous.
