Phylogenetic supports for the nesting of Archaeolemur (and Hadropithecus) within different taxa (Indriidae, Lemuridae, Cheirogaleidae, Lepilemuridae, Lorisiformes or the Aye-aye, respectively) are given in the 6 last columns. Bootstrap percentages or Posterior probabilities are given for Likelihood and Bayesian analyses, respectively. * In this topology, Archaeolemur actually appears as the sister taxon of the aye-aye but both are nested within paraphyletic indriids. This finding most likely results from a Long Branch Attraction artifact.
