|Types||Holotype: MNHN-RA 1966.1001|
|Diagnosis||Diagnosis. Lygodactylus arnoulti, a species endemic to the central massifs of Ibity and Itremo, 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. decaryi, L. heterurus, L. klemmmeri, and L. verticillatus by the characteristic dorsal pattern with grey ground colour and ocellae or short dark transversal markings (vs. absence a clear dorsal pattern, sometimes with a tendency of longitudinal striation in L. verticillatus, light dorsolateral bands in L. klemmeri, or pairs of large light markings in L. heterurus); from L. heterurus and L. klemmeri by the absence of longitudinal dark lines on the throat (vs. presence); from L. verticillatus by the absence of contact between the posterior projection of the mental scale and the first infralabials (vs. usually presence); from L. decaryi and L. verticillatus by a larger body size (mean SVL 30.2 mm vs. 25.1 and 23.1 mm); from L. decaryi by a lower number of preanal pores in males (9–11 vs. 15). Distinction is most difficult from L. blancae; however, the dorsal pattern of that species is also less distinctly ocellated or marked with transversal markings than in L. arnoulti, and L. arnoulti usually has few or no dark spots on the throat whereas L. blancae has usually many such spots, sometimes forming indistinct longitudinal lines.|
