Interspecific nucleotide sequence differences in the cytochrome B gene of indriidae (Primates, Strepsirhini).

The comparison of partial sequence of the mitochondrial cytochrome b gene nucleotides for different Indriidae allowed us to confirm the species status ofAvahi laniger, A. occidentalis, and Propithecus tattersalli. The nucleotide sequence allowed also to propose a phylogenetic tree which is discussed taking into account morphological, cytogenetic and former molecular biology data.
