Monodelphis (Mygalodelphys) peruviana

(Osgood, 1913)

TYPE MATERIAL AND TYPE LOCALITY: FMNH 19362 , the holotype by original designation, consists of the skin and skull of an adult male collected at Moyobamba (6.05° S, 76.97° W; 860 m), San Martín department, Peru .

SYNONYMS: None.

DISTRIBUTION: Specimens currently referred to Monodelphis peruviana (e.g., those examined by Pavan et al., 2016) are from northern Bolivia (La Paz) and eastern Peru (south of the Amazon) with recorded elevations from a few hundred meters in the Amazonian lowlands to 2600 m in the Andes. Pacheco et al. (2020) discussed the Peruvian distribution of this species.

REMARKS: No emended description of this species has been published; however, measurement data were tabulated by Voss et al. (2019), and cranial illustrations are in Pavan et al. (2017). As explained by Voss et al. (2019), Monodelphis peruviana does not appear to be morphologically distinguishable from the species on the north bank of the Amazon that is currently called M. adusta , even though these are not sister taxa ( Pavan et al., 2014). Although M. peruviana has consistently been recovered as a strongly supported clade by phylogenetic analyses of mtDNA sequence data, the same analyses have shown that this species includes three highly divergent and geographically disjunct haplogroups that merit closer study ( Solari, 2007; Pavan et al., 2014; Ruelas and Pacheco, 2022).
