Abstract

A cytogenetic study has been performed on Hapalemur griseus caught in different locations of the eastern and northern forests of Madagascar. This allowed the determination of the more precise distribution areas of the different subspecies and the isolation of a new cytogenetic polymorphic subspecies of H. griseus. The chromosomal changes distinguishing the different subspecies are Robertsonian translocations and gain of heterochromatin. The phylogeny established on chromosome comparison is compatible with the geographic distribution of the subspecies.
