Note the degree of morphological variation, which was used by Voss et al. (2019) and Voss (2022) in the delimitation of M. myosuros. Morphological variation of populations from eastern Amazonia,Tapajós basin,north of the state of Mato Grosso (region of the Teles Pires and Juruena rivers) and the Pantanal region, expand the variation presented in this table for the two subspecies.
