Classification
The diademed sifaka and four other sifaka species form a tight species group within the Propithecus genus. The other four species are Milne-Edwards' sifaka (Propithecus edwardsi), Perrier's sifaka (P. perrieri), the golden-crowned sifaka, (P. tattersalli), and the silky sifaka (P. candidus). All of these species have luxuriant silky coats and are powerful leapers. They share similar characteristics of gestation length (four months), age of sexual maturity, female dominance, life expectancy (18 years) and propensity for sunbathing while stretched out on a branch. They differ distinctly in colouration and markings, except for having universally totally black faces.
