Abstract: Morphological variation was investigated in 56 live adult specimens (3 1 male, 25 female) and ten dead near-hatching embryos of G. simonyi machadoi from the "Centro de Reproducción e Investigación del lagarto gigante del Hierro" (Frontera, El Hierro). Dimensions, scalation and teeth traits were measured and quantified. Males and females differed significantly (multivariate analysis of variance) in most of these traits, with values for males being greater than those for females. All traits significantly increased with SVL at a greater rate in males than in females, except for body weight, where no significant difference was found. A qualitative comparison between data from G. s. machadoi and those for ten G. s. simonyi showed that for most biometric traits, ranges overlapped for the two subspecies, but mean and maximum values were higher in G. s. simonyi. Hind limb length increased at a greater rate relative to SVL in G. s. simonyi than in G. s. machadoi.
