Taxonomy notes

Bublitz (1987) treated Lestoros as a synonym of Caenolestes, however, mitochondrial (cytochrome b; Ojala-Barbour et al. 2013) and skull and dental morphometric data (Martin 2013) support the recognition of Lestoros as a distinct genus from both Caenolestes and Rhyncholestes, and suggests a sister relationship with Rhyncholestes. Bublitz (1987) also described the name _C. gracilis_, which has been treated as a synonym of _L. inca_ by most authorities following its description (e.g., Myers and Patton 2008); this was morphologically validated by Martin (2013), who found little skull and dental morphological variation across the species distribution, suggesting there are no recognizable subspecies either. Monotypic.
