(2010)redescribed this species, summarized morphometric data, and provided comparisons with congeneric taxa.  Thylamys venustusincludes three robustly supported haplogroups, but none is morphologically diagnosable from the others. Phylogenetic analyses of multilocus sequence datasets ( Giarla et al., 2010; Díaz-Nieto et al., 2016a; Amador and Giannini, 2016) consistently recover  T. venustusand  T. sponsoriusas sister species.
