|Types||Holotype: MNHN-RA 263 (= MNHP 2818), Cape of Good Hope, South Africa (in error), collected Delalande.|
Holotype: USNM 12205 [Euprepis venustus]
|Diagnosis||Diagnosis (genus). The genus Chioninia represents the only lineage of skinks from the Cape Verde archipelago, from which it is endemic. It differs from other African, Asian and American genera formerly included in the genus Mabuya sensu lato by the following combination of characters: palatine bones in contact in the median; palatal notch separating the pterygoids, extending forwards to between the centre of the eyes; pterygoid teeth absent or present; 26–27 presacral vertebrae; reproduction either viviparous or ovoviviparous; the most posterior supraocular contacted by the frontal is always the third (Mausfeld et al. 2002); and supranasals are always in contact (Miralles et al. 2010).|
|Comment||Interparietal and parietals fused (unique in skinks).|
Distribution: The type locality was erroneously reported as “cap de Bonne-Espérance” by DUMÉRIL & BIBRON 1839.
Type species: Euprepes delalandii DUMÉRIL & BIBRON 1839: 690 is the type species of the genus Chioninia GRAY 1845. See Art. 69, ICZN 1999.
|Etymology||Named after Pierre Antoine Delalande (1787-1823) who worked for the Museum National d'Histoire Naturelle, Paris. He collected in South America and South Africa with Andrew Smith (1818) and others. Later Geoffroy Saint-Hilaire employed him as a taxidermist.|
