Cryptonanus unduaviensis ( Tate, 1931)

TYPE MATERIAL AND TYPE LOCALITY: AMNH

72563, the holotype by original designation, consists of the skin and skull of an adult male collected at Pitiguaya (ca. 16.35° S, 67.78° W; 1740 m), La Paz department, Bolivia .

SYNONYMS: None.

DISTRIBUTION: Cryptonanus unduaviensis is known from savannas and other open habitats in southeastern Peru (Madre de Dios), eastern Bolivia, southwestern Brazil (Mato Grosso), and western Paraguay ( Medina et al., 2016; Fegies et al., 2021: fig. 1).

REMARKS: For an emended description see Voss et al. (2005), who also tabulated measurement data from eight referred specimens. Phylogenetic analyses of DNA sequence datasets (e.g., Dias et al., 2016; Teta and Díaz-Nieto, 2019; Fegies et al., 2021) have consistently recovered Cryptonanus unduaviensis as the sister species to a clade that contains all the other species in this genus.
