Avahi occidentalis von Lorenz-Liburnau 1898
Avahi occidentalis von Lorenz-Liburnau 1898, Abh. Senckenb. Naturf. Ges., 21: 452.
Type Locality: Madagascar, Ambondrobe, NE of Bombetoka Bay, ca. 15°38’S, 46°24’E (according to lectotype selection by Thalmann and Geissmann, 2000).
Vernacular Names: Western Woolly Lemur.
Distribution: Madagascar: Betsiboka River north as far as Mahajamba or Sofia Rivers, perhaps to Maevarano River.
Conservation: CITES – Appendix I; U.S. ESA – Endangered; IUCN – Vulnerable.
Discussion: Rumpler et al. (1990) suggested that occidentalis may be a distinct species, and they were followed by Thalmann and Geissmann (2000), who drew attention to a population in the Bemaraha district at 18°59’S, 44°45’E, which they suggested is likely to represent a further, undescribed species.
