Chioninia fogoensis
Chioninia fogoensis (English: Fogo skink or Santo Antão skink) is a species of skink in the family Scincidae. It is endemic to the island of Santo Antão, Cape Verde. The species was named by Arthur William Edgar O'Shaughnessy in 1874. After revision of the species in 2010 based on molecular evidence, it no longer includes the skinks of São Nicolau (Chioninia nicolauensis), nor of the original type locality Fogo (hence the species name fogoensis).

Introduced populations
In 2020, the presence of Chioninia fogoensis was confirmed on the island of Madeira after an individual stowed away in a holidaymaker's bag and ended up in the United Kingdom before discovery.
