Lemuridae

Hapalemur griseus ranomafanensis Rabarivola, Prosper, Zaramody, Andriaholinirina & Hauwy, 2007: 48. “Reserve of Ranomafana (approx. 21°20’– 21°21’ S, 47°47’E)” [ Madagascar].

Remarks: Although colour details were mentioned in the type description of H. g. ranomafanensis, the status of this form is impossible to determine because at the same time no such details were given for H. g. griseus ; the essence of the new subspecies was, in effect, that it is chromosomally polymorphic at Ranomafana and Ambongo (2n = 54, 55 or 56, whereas in H. g. griseus 2n = always 54), while at Ambolomavo, Bemaraha and Vatoalatsaka, also ascribed to this new subspecies, only 2n=56 occurs.

Hapalemur griseus gilberti Rabarivola, Prosper, Zaramody, Andriaholinirina & Hauwy, 2007: 48. “Beanamalao (approx. 47°48’S, 19°50’E), Province Fianarantsoa, Madagascar ”.

Remarks: Elevated to species level by Mittermeier et al. (2008) under the Phylogenetic Species Concept.
