DistributionEquatorial Guinea (Annobon Island)

Type locality: Annobon Island  
Reproductionoviparous (phylogenetic imputation, fide Zimin et al. 2022) 
TypesHolotype: lost, was MB (loss of collection by fire in 1978), from Annobom, collected by F. Newton. It is unclear how many specimens were seen by Bocage. Only a single set of measurements was provided, but the description states that the species was common at the type locality. 
DiagnosisDiagnosis: Trachylepis ozorii is a medium-sized skink (SVL 63.9–85.9 mm) with a tail approximately 1.8 times SVL. Large and acuminate head (HW/HL 60,7%), 21.2 % as long as SVL. Supraciliaries usually 7, sometimes 6; five labials anterior to subocular; rectangular and enlarged subocular, in direct contact with the lip and not reduced basally by the intrusion of adjacent supralabials. Prefrontals always in contact. Supranasals always separated. Midbody scales rows 34–36, paravertebral scales 58–61, with three keels on vertebral and dorsal scales. Lamellae beneath the fourth finger 15–17, beneath the fourth toe 20–23. Digital lamellae keeled and spinose.
Back uniformly olive-green with many dark speckles and irregular dots and belly light green in alcohol- preserved specimens; infralabials and supralabials greenish, mental yellowish; absence of distinct longitudinal stripes or transverse dorsal bands. Colour in life olive-green on dorsum, with many dark speckles and irregular dots. Venter uniform yellowish-green [from CERIACO et al. 2016].
