“…This might favour the arrival of different higher clades in South America, thus allowing the diversification of more than one lineage. A similar means of arrival in South America has often been proposed for the hystricognath rodents 24 , the dispersal of amphisbaenian and gekkotan lizards 25 , and the Opisthocomiformes, a Neotropical group of birds (hoatzins) with weak flight capabilities and alleged African origin 26 . And, with the discovery of the Santa Rosa primates, the re-established, relatively contemporaneous first appearance datum of primates and rodents in South America leads to consideration of possible similarities of intercontinental dispersal mechanisms for the two mammalian groups.…”

The platyrrhine primates, or New World monkeys, are immigrant mammals whose fossil record comes from Tertiary and Quaternary sediments of South America and the Caribbean Greater Antilles. The time and place of platyrrhine origins are some of the most controversial issues in primate palaeontology, although an African Palaeogene ancestry has been presumed by most primatologists. Until now, the oldest fossil records of New World monkeys have come from Salla, Bolivia, and date to approximately 26 million years ago, or the Late Oligocene epoch. Here we report the discovery of new primates from the ?Late Eocene epoch of Amazonian Peru, which extends the fossil record of primates in South America back approximately 10 million years. The new specimens are important for understanding the origin and early evolution of modern platyrrhine primates because they bear little resemblance to any extinct or living South American primate, but they do bear striking resemblances to Eocene African anthropoids, and our phylogenetic analysis suggests a relationship with African taxa. The discovery of these new primates brings the first appearance datum of caviomorph rodents and primates in South America back into close correspondence, but raises new questions about the timing and means of arrival of these two mammalian groups.

“…Despite that Africa and South America separated completely around 100 Ma, transatlantic migration is the most supported colonization route for many animal groups in different time periods (e.g. Mayr et al ., ; Kergoat et al ., ; Bond et al ., ). The third is the trans‐Antarctic route (TAN).…”

Aim Multiple biogeographical scenarios involving vicariance and different colonization routes can explain disjunct species distributions in the Southern Hemisphere. Here, we tested several alternative hypotheses in Eneopterinae crickets, a diverse subfamily presenting a disjunct worldwide distribution. We inferred a dated phylogeny of Eneopterinae and reconstructed their biogeographical history to unravel the origin of their present-day distribution, focusing on their multiple origins in the Neotropics.Location Worldwide.Methods We sampled 62 eneopterine species representing all extant genera. We inferred their phylogenetic relationships through Bayesian and maximum likelihood approaches based on four mitochondrial and three nuclear gene sequences. Divergence time estimates were inferred using Bayesian relaxed clock approaches and primary fossil calibrations. Biogeographical analyses were conducted with the default dispersal-extinction-cladogenesis (DEC) model and a variant model (DEC+J), which accounts for rare-jump dispersal events. ResultsOur dating analyses showed that the Eneopterinae is far older than expected and its diversification can be traced back to the Late Cretaceous (c. 76 Ma). In this context, the most supported biogeographical scenario (under DEC+J) suggests that the Neotropics were colonized twice independently: first during the break-up of Gondwana, when Antarctica, Australia and South America started separating (compatible with a vicariance event if relying on the result of the DEC model alone); later through a northern recolonization originating from Southeast Asia, likely related to a Holarctic Boreotropical distribution of an eneopterine lineage during the Eocene. Main conclusionsWe provided a dated worldwide biogeographical framework for the Eneopterinae crickets. Overall, the subfamily disjunct distribution pattern is better explained by both ancient and recent dispersal events. Whether this could reflect a widespread pattern in insect groups exhibiting a disjunct distribution remains to be investigated by studying other insect lineages. The information gathered here will also help foster new directions for future studies concerning the acoustic innovations of this clade.We used the software Muscle (Edgar, 2004) with default parameters, implemented in Mega 6.0 (Tamura et al., 2013) to align the sequences. With Mega, we also checked if the protein-coding genes were congruent with codon reading frames. We conducted preliminary maximum likelihood

“…The North Equatorial Countercurrent originating off north‐eastern South America could provide the means for such an event, with winds playing an important role, although neither the current nor winds originate directly on the coast (Grodsky et al ., ; Renner, ). Dispersing across water on floating islands – rafting on tangled plants and soil – has been postulated for transoceanic dispersal by animals (Houle, ; Poux et al ., ; Vidal et al ., ; de Oliveira et al ., ; Rowe et al ., ; Mayr et al ., ; Gillespie et al ., ; Pyron, ), and the total oceanic trip riding an equatorial current can take under 2 weeks in either direction under ideal conditions (Renner, ). Heraty () hypothesized dispersal by means of ship ballast, as part of an intercontinental trade route.…”

Aim An ant parasitoid wasp genus (Eucharitidae: Kapala) common in the New World exhibits the intriguing pattern of having one species distributed widely across tropical Africa and Madagascar. The unusual distribution prompted an investigation of the age, origins and diversification of the Afrotropical Kapala species. We evaluate a previous hypothesis that the species was anthropogenically introduced. Location Africa and Madagascar and the Neotropics. Methods Numerous forms of evidence are incorporated to explain the origin of the Afrotropical species Kapala ivorensis, including phylogenetic relationships, molecular dating estimates, inter‐ and intraspecific genetic distances, morphology and geography. A phylogenetic analysis was performed using six gene regions (18S, 28S‐D2, 28S‐D3‐D5, ITS2, COI and COII), and network and haplotype analyses were executed with subsets of the data. Two mitochondrial gene fragments were used to calculate divergence times under a strict clock model. Additionally, we tested for a correlation between genetic distance and geographical distance in K. ivorensis populations. Results Phylogenetic analysis supports one evolutionary origin of K. ivorensis from within a clade of New World relatives. Network and haplotype analyses of the species show no biogeographical structure, and additionally, there is no statistical phylogeographical signal. These results, in conjunction with the low amount of phenotypic intraspecific variation and the genetic distance to the nearest New World relative, provide sufficient evidence to maintain the Old World Kapala as one species. Estimated mitochondrial mutation rates suggest that this species is over 1 Myr old, thus predating any potential for recent human introduction. Main conclusions Multiple analytical methods indicate the Afrotropical K. ivorensis is molecularly distinct from the Neotropical sister species and originated from a single pre‐human dispersal. This is the first dated example of an insect that has colonized Africa via trans‐Atlantic dispersal from South America.
