DistributionMadagascar (Mount Mandritsara)

Type locality: Mont Mandritsara, N Madagascar  
TypesHolotype: MNHN-RA 1939.0048 
DiagnosisDiagnosis. Lygodactylus ornatus differs from all other Malagasy Lygodactylus by its transversally striped pattern on the throat (vs. no pattern, isolated or dense black spots, or longitudinal black lines in the other species). The species is further distinguished from species in the L. madagascariensis group by the semidivided 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; and from the species in the L. verticillatus group by a non-whorled tail (vs. whorled). Further differences to unclassified species are as follows: L. ornatus differs from L. tolampyae by the indistinct (vs. broad and distinct) contact of the posterior part of the mental with first supralabial. (PUENTE et al. 2009) 
CommentHas been (erroneously ?) reported from Tanzania. PASTEUR’s paper was published only in 1965 although the journal was labeled “1964”.

Abundance: only known from the type locality (Meiri et al. 2017). 
Etymologyfrom Latin ornatus (ornamented), by implication referring to the pattern, ”7 lignes noires transversales, légèrement onduleuses. Deux paires de belles taches scapulaires à partie médiane noire et parties latérales blanches (une paire en avant du bras et l’autre en arrière)“ (according to the original description).
