DistributionN Madagascar (Ankarana Massif, Mangindrano [Tsaratanana])

Type locality: Karst of Ambilobe, Massif de l’Ankarana, Eastern slope.  
TypesHolotype: MNHN-RA 1990.0006 (given as “collection des auteurs”) 
DiagnosisDiagnosis. A rather large-sized endemic of limestone karst areas of northern Madagascar, characterized by a long-legged, long-tailed and slender appearance. It can clearly be assigned to the L. madagascariensis group by sharing the characters listed in the group definition above. It differs from all species in the L. madagascariensis group by the presence (vs. absence) of broad crossbands in the tail, of alternate light grey/ dark grey colour. Furthermore distinguished from L. miops and especially L. guibei by the absence (vs. presence) of dorsolateral tubercles and spiny tubercles at the tail base. Further distinguished from the sympatric L. expectatus by its non-enlarged dorsolateral scales (vs. enlarged), absence of dark spots on the neck (vs. presence), and larger size (adult SVL 31.6–36.5 mm vs. 27.0–29.7 mm).
CommentHabitat: karstic limestone massif of Ankarana. Specimens were active during the day, on big karstic rocks in an area with reduced vegetation (Puente et al. 2009). 
Etymologyderived from Latin rarus (rare, unusual).
