In his highly influential book Primate Taxonomy, Colin Groves discusses the importance of having an accurate account of primate taxa in order to understand evolutionary relationships that exist between species. This includes understanding genetic and morphological similarities between species as well as the processes of speciation. As the most widely ranging Neotropical monkey, the evolutionary relationships of the genus Alouatta have been examined from behavioural, morphological and most recently genetic data. According to Groves (2001) there are nine or 10 species of Alouatta and up to 19 subspecies (Table 4.1). Of these species, three are found in Mesoamerica: A. palliata, A. pigra and A. coibensis, with the rest located in South America. However, a more recent study of the molecular genetics of these species revealed A. coibensis to be indistinct from A. palliata, leaving A. pigra and A. palliata as the two remaining species in the Mesoamerican clade of howlers (Cortes-Ortiz et al., 2003). In 2012, while at a conference in Mexico, the lead author asked Colin what his thoughts were on the potential role of severe weather in speciation events, and more specifically on the biogeographical distribution on these two closely related species. He admitted he had never given it much thought, but was intrigued by the idea. This chapter further investigates this idea, by pulling together an array of evidence for both A. pigra and A. palliata in an attempt to add another piece to the puzzle of what factors are important in defining species.
