Antillothrix
The Hispaniola monkey (''Antillothrix bernensis'') is an extinct primate that was endemic on the island of Hispaniola, in the present-day Dominican Republic. The species is thought to have gone extinct around the 16th century. The exact timing and cause of the extinction are unclear, but it is likely related to the settlement of Hispaniola by Europeans after 1492. Description Horovitz and MacPhee developed the hypothesis, first proposed by MacPhee et al., that all the Antillean monkeys (the others being the two Cuban monkey species of genus ''Paralouatta'', and the Jamaican monkey, ''Xenothrix mcgregori'') belonged to a monophyletic group linked most closely with the modern genus ''Callicebus''. They later assigned the Antillean monkeys to the tribe Xenotrichini – the sister group of the tribe Callicebini with extensive anatomical comparisons and by extending their parsimony analysis using PAUP*. They maintained that the monophyly of the Antillean monkeys was still supporte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pitheciidae The Pitheciidae () are one of the five families of New World monkeys now recognised. Formerly, they were included in the family Atelidae. The family includes the titis, saki monkeys and uakaris. Most species are native to the Amazon region of Brazil, with some being found from Colombia in the north to Bolivia in the south. Characteristics Pithecids are small to medium-sized monkeys, ranging from 23 cm in head-body length for the smaller titis, to 44–49 cm for the uakaris. They have medium to long fur, in a wide range of colors, often with contrasting patches, especially on the face. They are diurnal and arboreal animals, found in tropical forests from low-lying swamp to mountain slopes. They are predominantly herbivorous, eating mostly fruit and seeds, although some species will also eat a small number of insects. Sakis and uakaris have a diastema between the canine and premolar teeth, but the titis, which have unusually small canines for New World monkeys, do not ... [...More Info...] |
