Comparison between the intra- and interspecific effect (Dataset 3) of the allometry and cranial shape in Lygodactylus dwarf geckos. A – Multivariate regression between size (Log centroid size) and cranial shape (Regression score). Note that cranial representations are an interpolated form based on the TPS technique to extrapolate visual difference of the cranium shape variations. Geometric symbols depict the Malagasy (stars), African (circles) and American species (squares). Triangles depict intraspecific variation. See inset for explanatory of the symbols. B – Interspecific variation of skull shape. Above, the largest skull (Lygodactylus rex, PEM R16300, skull length (SL) = 12.8 mm), and below the smallest (L. somalicus somalicus, MCZ R35558 (holotype), SL = 6.62 mm) included in the analysis in dorsal, lateral, ventral view of the cranium and lateral left jaw. C – Intraspecific variation of skull shape in Lygodactylus kibera. Above, the largest skull (UTEP 22571, SL = 10.54 mm), and below the smallest (UTEP 22576, SL = 7.98 mm), included in the analysis in dorsal, lateral, ventral view of the cranium and lateral left jaw
