Genus Cryptonanus Voss et al., 2005

TYPE SPECIES: Marmosa agilis chacoensis Tate, 1931 , by original designation.

SYNONYMS: None.

REMARKS: See Voss and Jansa (2009) for an emended generic description. Phylogenetic analyses of multilocus sequence datasets strongly support generic monophyly and convincingly recover Cryptonanus and Chacodelphys as sister taxa in a larger clade that includes Gracilinanus , Lestodelphys , and Thylamys , but not Marmosops ( Díaz-Nieto et al., 2016a; Fegies et al., 2021). Of the five species originally referred to Cryptonanus by Voss et al. (2005), only four are now recognized as valid. Currently recognized species of Cryptonanus are all from south of the Amazon (in Brazil, Paraguay, Bolivia, Uruguay, and Argentina), but specimens of a possibly undescribed species have been reported from Amapá ( Silva et al., 2013) and French Guiana (Baglan and Catzeflis, 2016).
