“…We compiled mtDNA identifications of A. jamaicensis, A. planirostris, and A. schwartzi from throughout the Neotropics using the sequence data presented here and mtDNA-based identifications previously reported or summarized (20,22,26,27). A. jamaicensis haplotypes were distributed west of the Andes Mountains in South America (n = 15), throughout Central America (n = 22), and throughout the Greater and Lesser Antilles (n = 57).…”

Most diploid species arise from single-species ancestors. Hybrid origins of new species are uncommon (except among polyploids) and are documented infrequently in animals. Examples of natural hybridization leading to speciation in mammals are exceedingly rare. Here, we show a Caribbean species of bat (Artibeus schwartzi) has a nuclear genome derived from two nonsister but congeneric species (A. jamaicensis and A. planirostris) and a mitochondrial genome that is from a third extinct or uncharacterized congener. Artibeus schwartzi is self-sustaining, morphologically distinct, and exists in near geographic isolation of its known parent species. Island effects (i.e., area, reduced habitat variability, and geographic isolation) likely have restricted gene flow from parental species into the Caribbean populations of this hybrid lineage, thus contributing to local adaptation and isolation of this newly produced taxon. We hypothesize differential rates of the development of reproductive isolation within the genus and estimate that 2.5 million years was an insufficient amount of time for the development of postzygotic isolation among the three species that hybridized to produce A. schwartzi. Reticulated evolution thus has resulted in a genomic combination from three evolutionary lineages and a transgressive phenotype that is distinct from all other known species of Artibeus. The data herein further demonstrate the phenomenon of speciation by hybridization in mammals is possible in nature.Artibeus | Chiroptera | hybrid speciation | reticulate evolution | transgressive segregation D espite empirical studies documenting the establishment of animal hybrid lineages (1-8), the evolutionary importance of speciation by natural hybridization in animals is unknown and often is considered minor because the offspring of such crosses typically are less fit than either parental species (9, 10). Nearly all reported cases of homoploid speciation events (hybrid speciation without change in chromosome number) (11) in animals are among species of insects or fish (12), and there are only a handful of suspected cases in mammals (13-17). Thus hybrid speciation appears to be especially rare in mammals, a consequence of either unfavorable conditions for hybrid speciation to occur (i.e., ecological, physiological, hybrid zone structure) or a lack of empirically based research (18,19). Here, we describe a zone of admixture on a series of Caribbean islands within which three species of Neotropical bats have hybridized resulting in a novel lineage with species-level distinction. Our genetic and morphometric analyses have identified a unique hybrid zone among species of fruit-eating bats, leading us to the hypothesis that natural hybridization has generated a distinct lineage that exists in these insular populations. Our data also indicate that this phenotypic and genotypic combination is geographically isolated from extant parental species on the southern Lesser Antillean island of Saint Vincent.Two species of fruit-eating bats, Artibeus jamaicensis...

“…The bat flies were identified with the aid of a stereoscopic microscope, using dichotomous keys and descriptions (WENZEL et al, 1966;WENZEL, 1976;GUERRERO, 1994GUERRERO, , 1995GUERRERO, , 1996GUERRERO, , 1998CARVALHO, 2001;MILLER;TSCHAPKA, 2001). The nomenclature followed Dick and Graciolli (2006) for Streblidae and Gardner (2007) for bats, except for Dermanura which has been elevated to generic status (REDONDO et al, 2008;SOLARI et al, 2009). The vouchers were confirmed by Dr. Gustavo Graciolli and were deposited in the zoological reference collection of the Federal University of Mato Grosso do Sul in the city of Campo Grande, Brazil.…”

Because of the few records of Streblidae on bats, despite extensive study on these mammals in the state of Rio de Janeiro, a survey was carried out in an area of Atlantic Forest, in the municipality of Nova Iguaçu, known as the Tinguá region. Thirteen species were added to the list of Streblidae in the state of Rio de Janeiro, of which two were new records for Brazil. Thirty-one species have now been reported this state.

“…We included a thorough analysis of the Cytb in a large geographic sampling in South America, such as has been shown to be useful in recovering mammalian phylogeny and exposing cryptic species (Baker and Bradley 2006;Redondo et al 2008). Sequence alignments were performed using Clustal W 2.1 (Larkin et al 2007) and edited or concatenated, or both, when necessary with the Alignment Explorer function implemented in MEGA 5.1 (Tamura et al 2011).…”

All known species of extant tapirs are allopatric: 1 in southeastern Asia and 3 in Central and South America. The fossil record for tapirs, however, is much wider in geographical range, including Europe, Asia, and North and South America, going back to the late Oligocene, making the present distribution a relict of the original one. We here describe a new species of living Tapirus from the Amazon rain forest, the 1st since T. bairdii Gill, 1865, and the 1st new Perissodactyla in more than 100 years, from both morphological and molecular characters. It is shorter in stature than T. terrestris (Linnaeus, 1758) and has distinctive skull morphology, and it is basal to the clade formed by T. terrestris and T. pinchaque (Roulin, 1829). This highlights the unrecognized biodiversity in western Amazonia, where the biota faces increasing threats. Local peoples have long recognized our new species, suggesting a key role for traditional knowledge in understanding the biodiversity of the region.
