SYNONYMS: None. REMARKS: Although the monophyly of Xerodelphys has been consistently supported by phylogenetic analyses of multilocus sequence datasets (e.g., Giarla et al., 2010 ; Díaz et al., 2016a; Amador and Giannini, 2016), nodal support for this clade is seldom strong. However, compelling evidence for subgeneric monophyly is provided by the unusual caudal and manual morphologies illustrated by Carmignotto and Monfort (2006). Two species are currently recognized as valid.
