Abstract:
A review of the phylogenetic relationships of the subfamilies of Simaroubaceae is presented and the distribution patterns of the American genera are discussed. Engler's six subfamilies are evaluated and the three subfamilies represented in the Americas and their included genera are discussed in detail. The eight American genera fall into three broad distributional categories: widely distributed throughout the neotropics, limited to northern South America, and disjunct between the West Indies, Central America and Mexico and southern South America. These distributions are discussed and interpret

Abstract:
In the course of a detailed molecular study of the tribe Gochnatieae (Compositae: Gochnatioideae) it became apparent that the genus Gochnatia (sensu Cabrera) was not monophyletic but composed of a number of morphologically, geographically, and molecularly distinct clades. All but one of these clades had previously been recognized at the generic or sectional level and therefore had a name that could be applied. However, one clade, whose members are from Mexico and adjacent parts of the United States, had never been recognized as a distinct taxon. The Mexican clade is the sister group of the Car

Abstract:
Abstract The intraspecific evolutionary history of South American xerophytic plant species has been poorly explored. The tree species Prosopis chilensis has a disjunct distribution in four South American regions: southern Peru, southern Bolivia, central–western Argentina and central Chile. Here, we combined phylogeographical (based on chloroplast and nuclear markers), morphological and climatic data to evaluate the relative contribution of historical demo-stochastic and adaptive processes in differentiating the disjunct areas of distribution. The results obtained with the two molecular markers

Abstract:
The historical biogeography of the major South American forested biomes has long intrigued scientists. Paleoclimatic events during the last 130 thousand years promoted connections between forested biomes in the Neotropical region, leading to disjunct distributions of some of the biota. In this context, MacConnell’s Bat, Mesophylla macconnelli, appears to represent a forest-restricted species with its current distribution bisected by dry areas. In this study, we infer past connections between the Amazonia and Atlantic Forest using MacConnell’s Bat and ecological niche models. We obtained 681 re

Abstract:
Mythicomyia Coquillett (1893) has a disjunct distribution (presence in every biogeographical region with the exception of the Palearctic) and is a poorly studied group in the Neotropical Region, and completely unknown in Colombia. Its subgenus Heterhybos Brèthes has a Nearctic and Neotropical distribution. Of the nine species in the Neotropical Region (in Argentina, Chile, and Uruguay), all occur in Chile and only one in Argentina and Uruguay. A new species of Mythicomyia (Heterhybos) is here described from Colombia: Mythicomyia (Heterhybos) bilobata sp. nov. (type-locality: Liborina, La Sucia

Abstract:
Plagiodontes dentatus (Wood, 1828) is the type species of a South American genus including eight named species that show a high degree of local endemism. Due to some misidentifications with P. multiplicatus (Doering, 1874) and P. daedaleus (Deshayes, 1851), P. dentatus has been cited as inhabiting two disjunct areas with quite different ecological conditions. In this paper the identity of this morphospecies is clarified through a study of shell sculpture and apertural teeth data, and a comparison with the smaller adult specimens (<25 mm long) of its closest species, P. patagonicus (d’Orbign
