collected at Tingo María (9.30° S, 75.98° W; 600 m), Huánuco department, Peru .

SYNONYMS: buenavistae Tate, 1931 (see Remarks).

DISTRIBUTION: Gracilinanus peruanus occurs in west-central Brazil (Mato Grosso and Rondônia), eastern Bolivia (Santa Cruz), and eastern Peru ( Semedo et al., 2022: fig. 4). In addition to the type locality (in Huánuco), G. peruanus is known from the Peruvian departments of Cusco, Madre de Dios, Pasco, and Ucayali ( Voss et al., 2019).

REMARKS: Gracilinanus peruanus was considered a synyonym of G. agilis by Creighton and Gardner (2008 b), but Semedo et al. (2015) showed that these species are genetically divergent, morphologically diagnosable, occur sympatrically, and are probably not sister taxa. The relationships of this species with other congeners, however, have yet to be convincingly resolved ( Díaz-Nieto et al., 2016a; Teta and Díaz-Nieto, 2019; Semedo et al., 2022). As first revisers in the sense of the Code ( ICZN, 1999: Article 24.2), Semedo et al. (2015) determined the priority of peruana Tate, 1931, over buenavistae Tate, 1931 (both names having first appeared in the same publication).
