DistributionSeychelles (Mahé, Silhouette, Frégate, Praslin)

Type locality: “Seychellen”  
Reproductionoviparous (not imputed, fide Zimin et al. 2022) 
TypesLectotype: SMF 16030 (=6411, 1a in Mertens, 1922). Designation by Mertens (1967) 
DiagnosisDiagnosis (genus): Similar to Gongylomorphus and Pamelaescincus and differing from all other scincines in having the palatines and palatal rami of the pterygoids meeting medially to form a broad secondary palate (Fig. 7 in GREER 1970); and in possessing 11, instead of 10 or fewer, premaxillary teeth. In skull morphology Janetaescincus differs from Gongylomorphus and Pamelaescincus in having the palatal rami of the pterygoids emarginated posteriorly (Fig. 7). On the basis of external characters the new genus is easily distinguished from Gongylomorphus and Pamelaescincus by means of its lower midbody scale count (22 to 24 instead of 30 to 38), and by the possession of only 4 fingers instead of 5. Janetaescincus also lacks the frontoparietals and clear spectacle in the lower eyelid of Gongylomorphus. The circular external ear opening is relatively smaller in Janetaescincus than in Pamelaescincus and, of course, is easily distinguishable from the horizontal slit in Gonglyornorphus [from GREER 1970]. 
CommentType species: Scelotes braueri BOETTGER 1896 is the type species of the genus Janetaescincus GREER 1970. 
EtymologyNamed after the collector, August Brauer, zoologist at the University of Marburg (Germany).

The genus was named after Janet Greer, the younger of the two sisters of Alan Greer.
