Mabuya dumasidiffers from M. elegans, M. gravenhorsti,and M. madagascariensis by having a rectangular subocular (trapezoidal in the latter three species); from M. aureopunctata and M. vato in lacking white spots on the dorsum of the head, neck, and anterior half of the body; further from M. aureopunctata in size, the maximum SVL of the latter is 82 mm, whereas the largest known M. dumasiis 55 mm SVL; and further from M. vato in having a brown rather than a black head and in having a brown body and tail rather than a reddish bronze posterior body and tail; from M. betsileana and M. boettgeriin having the distinctive pattern of white spots on the sides of the head and neck, which are lacking in these two species; and further from M. boettgeriin lacking the longitudinal light and dark stripes on the neck and body of that species. |
