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
[edit]Horovitz and MacPhee[1] developed the hypothesis, first proposed by MacPhee et al.,[2] 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[3] – the sister group of the tribe Callicebini with extensive anatomical comparisons and by extending their parsimony analysis using PAUP*.[4] They maintained that the monophyly of the Antillean monkeys was still supported in the most parsimonious trees, but in slightly less parsimonious trees, Aotus appeared to be linked with Xenothrix.
Skull discovery
[edit]In July 2009, Walter Pickel found a A. bernensis skull while diving in underwater caves. The skull was found in the La Jeringa Cave of Cotubanamá National Park. The skull, long bones and ribs were recovered by Walter Pickel and Curt Bowen in October 2009 under the supervision of the Dominican Republic and Alfred L. Rosenberger from Brooklyn College. The discovery supported the MacPhee et al. hypothesis of a monophyletic origin of the Antilles monkeys.[5] This 2009 discovery of the skull suggested that these primates were diurnal, due to their relatively smaller ocular orbits.[6]
New specimens published in 2024
[edit]New specimens recovered in 2018 from Cueva Macho included four crania and three mandibles. Both a cranium and mandible exhibited absent wisdom teeth, which is rare in most primates. Though previously, hypotheses regarding smaller relative brain size than normal and sexual dimorphism had been posited, these new specimens evidence neither of these claims. Instead, the authors posit that Hispaniolan monkeys were "a morphologically variable but monomorphic species."[7]
