FIGURE 11. Selected qualitative morphological traits differentiating Trans-Andean species of Neacomys present in Colombia: A), C), E) Neacomys sp. nov. B), D), F) N. tenuipes. Note the tegmen tympani exposed above the dorsal surface of the ectotympanic, the opened ectotympanic ring, the larger orbicular apophysis of the malleus, the bifurcated paraoccipital process, the deeper folds of the upper molars, and the divided mesoflexus of M1 in the new species. ab: auditory bullae; adeect: anterodorsal edge of the ectotympanic; hyp: hypoflexus; hp: hamular process of the squamosal; M1 prc: procingulum of first upper molar; mes: mesoflexus; met: metaflexus; mt: mastoid tubercle; oa: orbicular apophysis; par: paraflexus; pgf: postglenoid foramen; pp: paraoccipital process; pro: protoflexus; ssf: subsquamosal fenestra; tt: tegmen tympani.Published as part of Colmenares-Pinzón, Javier E., 2021, Calling for a reassessment of rodent diversity in Colombia: description of a new species of Neacomys (Cricetidae: Oryzomyini) from the Magdalena Valley, with a new phylogenetic hypothesis for the genus and comments on its diversification, pp. 451-494 in Zootaxa 4920 (4) on page 471, DOI: 10.11646/zootaxa.4920.4.1, http://zenodo.org/record/449111
