CommentDiagnosis. Lygodactylus blancae, a species apparently endemic to a small area in the central highlands, is characterized as a member of the L. verticillatus group as defined above by its clearly whorled tail. It differs from other species of the group as follows: from L. heterurus and L. klemmeri by the absence of distinct and well-defined longitudinal dark lines on the throat (although a large number of black spots can be present on the throat which sometimes form irregular longitudinal lines) and a yellow venter in life, especially in males (vs. presence of well defined throat lines and absence of yellow pigment of venter in life); from L. decaryi and L. verticillatus by a larger body size (mean SVL 30.3 mm vs. 25.1 and 23.1 mm); from L. decaryi by a lower number of preanal pores in males (9–11 vs. 15); from L. verticillatus by a pigmented throat with distinct black spots that sometimes form longitudinal lines (vs. no distinct dark spots on throat). Distinction is most difficult from L. arnoulti; however, this species has a clear dorsal colour and pattern (usually grey with a pattern of indistinct ocellae or of regularly arranged transversal dark lines or markings) whereas the pattern is more diffuse and variable in L. blancae, and L. arnoulti usually has only few or no black spots on the throat whereas in L. blancae the throat usually is densely spotted, the spots sometimes forming diffuse longitudinal lines.

Habitat. According to Pasteur (1995) this species was found living in small trees near the lake.
