DiagnosisDiagnosis. Madascincus irery sp. nov. differs from all other species in the genus Madascincus (except those of the nanus group) by a lower number of ventral scales (55, versus 56 to 88), a short and pointed snout with visibly enlarged eyes and a dark and uniform coloration (versus lighter coloration, most often with dark lateral stripes variable in contrast and length). Additionaly, it differs from the species of the nanus group by a higher number of scales around midbody (24, versus 18 to 20), and more elongated digits, with both a higher number of subdigital lamellae under the fourth finger (8, versus 3 to 5) and the fourth toe (12 to 15, versus 5 to 8). It differs from the species of the polleni group (its sister clade, formed by M. polleni, M. arenicola, M. stumpffi and M. miafina) by a distinctly lower number of ventral scales (55, versus 65 to 88) and of paravertebral scales (53 to 56, versus 65 to 88), a smaller size (33.8 to 39.9 mm, versus 54.9 to 89.6 mm), an hourglass-shaped frontal, i. e., constricted by the first pair of supraocular (versus always bell-shaped in all species except in M. stumpffi, where this state of character is variable), and a lower number of subdigital lamellae under the fourth toe (12 to 15, versus 15 to 23).

CommentDistribution: see map in Miralles et al. 2026: Fig. 12. 
EtymologyThe specific epithet irery, invariable noun in apposition, is derived from the Malagasy language, and means “ alone ” or “ solitary ”. It refers both to the assumption that this species seems to be isolated on the small island of Nosy Be and the fact that it represents a distinct long phylogenetic branch.
