FIGURE 2. Map showing collection localities of the named and unamed small-bodied species of Neacomys (except N. pictus) along with salient topographic features of northern South America. Localities of N. tenuipes and Neacomys sp. nov are numbered according to Appendix I. Localities of the remaining species are detailed in Voss et al. (2001), Sánchez-Vendizú et al. (2018), and Semedo et al. (2020). Miniature in the right side of the map corresponds to the Bayesian Cytb phylogeny recovered here (FIGURE 3): species in the map and phylogeny are same colored; the numbers in some nodes correspond to the median divergence times estimated by Upham et al. (2019) within Neacomys.
