Diagnosis. Lygodactylus tuberosus is a relatively small species of Lygodactylus that is common in the arid South of Madagascar. It can be assigned to the L. pictus group based on the characters listed in the group definition above. It differs from L. pictus by usually having only few and indistinct dark spots on the throat (vs. usually at least some distinct spots), and by a white or only faint yellowish ventral colour in life (vs. usually distinctly yellow; but the yellow pigment quickly fades in preservative), furthermore by the presence in most specimens of a dark marking behind the eye which includes spiny scales (vs. presence of only a dark stripe). Typically, specimens of L. tuberosus are relatively small, but some can attain large sizes (up to 38 mm). Clearly, the definition of this species requires revision. Distinction of L. tuberosus from L. roavolana is easily possible by the presence of only small black markings on the neck (vs. presence of large and very distinct markings above the forelimbs), and by the presence of a claw on the first finger (vs. apparent absence).
Habitat. L. tuberosus is a species inhabiting arid zones in the South. All localities are in this area. Specimens in the MNHN collection have been found on "Kily" trunks which refers to Tamarindus indicus trees. We observed the species active during the day, in open forests, on isolated trees or fallen tree trunks, and in dry bush areas (M. Puente & M. Thomas, personal observation, February 2003) [Puente et al. 2009].
