A Taxonomic Revision of the Saki Monkeys, Pithecia Desmarest, 1804

Abstract: For more than 200 years, the taxonomy of Pithecia has been floating on the misunderstanding of a few species, in particular P. pithecia and P. monachus. In this revision, historical names and descriptions are addressed and original type material is examined. For every museum specimen, all location, collection, and museum data were recorded, and photographs and measurements of each skin, skull, mount, or fluid specimen were taken. The revision is based on work conducted in 36 museums in 28 cities from 17 countries in North America, South America, Europe, and Japan, resulting in the examination of 876 skins (including mounts and fluids), 690 skulls, and hundreds of photographs taken by the author and by colleagues in the field of living captive and wild sakis of all species, and through internet searches. Per this revision, there are 16 species of Pithecia: five currently recognized, three reinstated, three elevated from subspecies level, and five newly described.

Further Notes on the Distribution of Endemic Bolivian Titi Monkeys, Callicebus modestus and Callicebus olallae

Abstract: We present information on the distribution of the endemic Bolivian primates Callicebus olallae and C. modestus based on a series of site visits in the Beni Department. Callicebus olallae was registered at four localities and C. modestus at 11 localities, and in combination with negative data and localities for other Callicebus species in the region we defined the distributional boundaries for both endemics. Mean group size was 2.7 individuals for C. olallae and 3 individuals for C. modestus. The results highlight the restricted distribution of both species, with C. olallae having one of the highest levels of primate endemism in the world and an “occurrence area” of 400 km2, and considering forest fragmentation in the region, more realistically an “occupancy area” of 50 km2. Although C. modestus is found in slightly larger areas (1,800 km2 and 450 km2 respectively) the distribution area is still extremely restricted. The restricted distributions together with ongoing forest fragmentation due to ca...

Limites Climáticos e Vegetacionais das Distribuições de Cebus nigritus e Cebus robustus (Cebinae, Platyrrhini)

Abstract: Os primatas do gênero Cebus apresentam ampla distribuição geográfica, estendendo-se por toda a região Neotropical. Os macacos-prego (subgênero Sapajus) são exclusivos da América do Sul, enquanto que os caiararas (subgênero Cebus) ocorrem na Amazônia e América Central. Estes animais são notáveis por explorarem habitats diversos. A proposta taxonômica utilizada no presente estudo foi desenvolvida por Silva Jr. (2001), considerando Cebus nigritus e C. robustus como espécies válidas, pertencentes ao subgênero Sapajus, que compreende ainda C. apella, C. macrocephalus, C. libidinosus, C. cay e C. xanthosternos.
