DistributionSE Madagascar

Type locality: Ambatomenaloha, 1600 m elevation, Masif de l’Itremo, 75 km W Ambositra.  
Reproductionoviparous 
TypesHolotype: MNHN 1990.7 
DiagnosisDiagnosis. A poorly known species, probably endemic to the Itremo Massif. Lygodactylus pauliani differs from species in the L. madagascariensis group by the semi-divided mental and three postmentals (vs. undivided with two postmentals) and by the presence (vs. absence) of a claw on the first finger; from the species in the L. pictus group by having three postmental scales (vs. usually two); from the species in the L. mirabilis group by granular (vs. keeled or partially keeled) dorsal scales; from the species in the L. verticillatus group by a non-whorled tail (vs. whorled); from L. ornatus by the absence (vs. presence) of transversal lines on the throat; and from L. tolampyae by the rather indistinct contact between posterior part of mental and first infralabial (vs. very distinct and broad contact).
 
CommentL. pauliani differs from all other species in this supergroup by its unregenerated tail bearing ventral scales marked by subregular alternating (quincunxial) arrangement, rather than periodic scale motifs repeated with vertebrae. In Madagascar, only Lygodactylus tuberifer, from another supergroup, has also staggered undertail scales, but L. tuberifer has neither three symetrically polygonal postmentals nor long contacts between first infralabials and the rear lobe of the mental plate, two usual traits of L. pauliani's.

Habitat: under stones in sandy grassland and in rocky areas with bushes.

Abundance: only known from the type locality (Meiri et al. 2017). 
Etymologydedicated to Renaud Paulian.
