DistributionC Madagascar

Type locality: Mont Ibity, 25 km SE Antsirabé, C Madagascar, elevation 2000-2100 m.  
TypesHolotype: MNHN-RA 1966.1003 
DiagnosisDiagnosis. A large species, endemic to high elevations on Ibity mountain. Assigned to the L. mirabilis group based on its partially keeled dorsal scales and slight ocellated/striated polymorphism of the dorsal pattern. L. blanci differs from L. mirabilis by being larger (maximum SVL 39.2 mm vs. 29.3 mm), having more preanal pores in males (10–12 vs. 7), a well developed first finger with claw (vs. first finger absent), and partially keeled dorsal scales (vs. fully keeled). It differs from L. intermedius by being larger (maximum SVL 39.2 mm vs. 30.9 mm), by having 10–12 preanal pores in males (vs. seven), a claw on the first finger (vs. claw absent), and partially keeled dorsal scales (versus fully keeled). It differs from L. montanus by presence of a claw on the first finger (vs. absence). Lygodactylus blanci occurs on Mont Ibity in sympatry with L. arnoulti which differs by a grey (vs. brown) ground colour, granular dorsal scales (vs. partially keeled), and a strongly whorled tail (vs. without whorls). (PUENTE et al. 2009) 
CommentHabitat: L. blanci was only found on the summital area itself, in an area characterized by large rocks, very little vegetation, and a quartzitic sand substrate.

Abundance: only known from the type locality (Meiri et al. 2017). 
EtymologyNamed after Charles Pierre Blanc (born 1933), French herpetologist.
