“…A number of extinct platyrrhines also have been described from the geologically young (Pleistocene-Holocene) cave deposits of the Greater Antilles, including Paralouatta (Cuba), Xenothrix (Jamaica) and Antillothrix (and possibly Insulacebus) from Hispaniola. As with other Antillean mammals, some of these species may have survived until the arrival of humans at about six thousand years ago (Steadman et al, 2005;MacPhee, 2009;Kay et al, 2011). In the phylogenetic analysis (Fig.…”

a b s t r a c tMolecular data have converged on a consensus about the genus-level phylogeny of extant platyrrhine monkeys, but for most extinct taxa and certainly for those older than the Pleistocene we must rely upon morphological evidence from fossils. This raises the question as to how well anatomical data mirror molecular phylogenies and how best to deal with discrepancies between the molecular and morphological data as we seek to extend our phylogenies to the placement of fossil taxa.Here I present parsimony-based phylogenetic analyses of extant and fossil platyrrhines based on an anatomical dataset of 399 dental characters and osteological features of the cranium and postcranium.

“…The Greater Antilles once harbored an endemic radiation of platyrrhine primates, including Antillothrix bernensis from the Dominican Republic (Rímoli, 1977;MacPhee et al, 1995;Kay et al, 2011;Rosenberger et al, 2011), Paralouatta varoni and Paralouatta marianae from Cuba (Rivero and Arredondo,1991;Horovitz and MacPhee,1999;MacPhee and Meldrum, 2006), Xenothrix mcgregori from Jamaica (Williams and Koopman, 1952;Rosenberger, 1977;MacPhee and Fleagle, 1991;MacPhee and Meldrum, 2006), and the recently named Insulacebus toussaintiana from Haiti . Along with nearly 80% of the endemic mammalian fauna, these primates became extinct sometime in the last several thousand years (Morgan and Woods,1986).…”

“…Since that time, a number of additional remains have been recovered from the eastern Dominican Republic, including numerous postcranial elements and two well-preserved crania (Kay et al, 2011;Rosenberger et al, 2011). The fossil record for Haitian primates is less complete, however.…”

“…Subsequent work at the same locality in 2010 produced more of the same individual, including the first mandible and lower dentition that can be reliably assigned to A. bernensis. Since the initial discovery and publication of the cranium, a second primate cranium from a nearby site was also described [Kay et al, 2011], and a new genus and species from Haiti, Insulacebus toussaintiana, was published . These new discoveries have prompted a rethinking of our interpretation of the phylogenetic position of Antillothrix and its consequences for the origins and biogeography of the West Indian primates.…”

A mandible of the Hispaniolan primate Antillothrix bernensis, virtually complete and providing the only definitive evidence of the species' lower dentition, has been discovered in a submerged Dominican Republic cave. The new specimen enables a more certain assessment of the species' phylogenetic position than previously possible. It belongs to the same individual as the nearly complete young adult cranium and postrcranial elements found earlier at the same site. Of the extinct Caribbean platyrrhines, the jaw compares well with partial mandibles representing Xenothrix mcgregori, from Jamaica. Among living platyrrhines, it closely resembles Callicebus and Aotus, as documented in a biometric analysis employing three-dimensional geometric morphometrics of Callicebus, Aotus, Pithecia, Chiropotes, Cacajao, Cebus, and Saimiri. The jaw falls within the morphological variability of Callicebus and Aotus in this three-dimensional analysis, is otherwise most similar to Pithecia, and is distinct from cebines. Lower molars resemble the Haitian primate, Insulacebus, a genus known by a full dentition and gnathic fragments with a pattern of derived features also present in Xenothrix. Considering the available craniodental and postcranial evidence, we conclude that Antillothrix is not properly classified as cebid but rather is best grouped with Pitheciidae, an idea long central to discussions of the phylogenetic affinities of the Greater Antillean primates. Since Antillothrix and Insulacebus are more primitive anatomically than the highly modified Xenothrix, it is tempting to surmise that the origins of the latter involved a vicariance or dispersal event via Hispaniola isolating it on Jamaica.
