Mochlus sundevallii, also known commonly as Peters' eyelid skink, Peters' writhing skink, and Sundevall's writhing skink, is a species of lizard in the family Scincidae.

The specific name, sundevallii, is in honor of Swedish zoologist Carl Jakob Sundevall.

[4] M. sundevallii is found in Angola, Botswana, Democratic Republic of Congo, Eswatini, Ethiopia, Kenya, Malawi, Mozambique, Namibia, Somalia, South Africa, Tanzania, Uganda, Zambia, and Zimbabwe.

[2] The preferred natural habitats of M. sundevallii are shrubland, savanna, and forest, at altitudes from sea level to 2,000 m (6,600 ft).

Ventrally, it is uniformly cream-colored, except for the underside of the tail, which may have speckling.
