|Diagnosis||Diagnosis. A Leiolopisma intermediate in adult size and robustness between the two Mauritian species of the genus, L. telfairii and the giant L. mauritiana. Most similar to L. telfairii but differs in larger maximum size, coarser dentition, frontal bone narrower anteriorly at least in young animals, the fused postorbital and postfrontal bones with shorter posterior section and less prominent lateral spur, and quadrate more expanded lateromedially. L. mauritiana grows much larger than L. ceciliae and has coarser dentition. L. ceciliae is also separated from L. telfairii and L. mauritiana by distinctive mitochondrial DNA sequence (12S rRNA and cytochrome b gene fragments).|
Fossil remains distinguished from those of the sympatric skink Gongylomorphus bojerii borbonicus by larger size, fused frontal bones and absence of a Meckel’s groove in the dentary.
|Comment||Conservation: Probably extinct; this species has been described based on subfossil remains and DNA data.|
|Etymology||Named after Cécile Mourer-Chauviré, celebrated specialist on fossil birds, who took part in excavations for subfossil remains on La Réunion between 1987 to 2001, identifying half a dozen of new species of birds. She also proposed the hypothesis of a ‘great extinction’ on the island, associated with cataclysmic volcanic eruptions, 180,000–230,000 years ago (Mourer-Chauviré et al., 1999).|
