Marmosops (Marmosops) soinii Voss et al., 2019

TYPE MATERIAL AND TYPE LOCALITY: MUSM 13284, the holotype by original designation, consists of the fluid-preserved body, extracted skull, and frozen tissues of an adult male collected at Nuevo San Juan (5.25° S, 73.17° W), a Matses Indian village on the right bank of the Río Gálvez, Loreto department, Peru.

SYNONYMS: None.

DISTRIBUTION: Marmosops soinii is currently known from only three localities in the Yavarí- Ucayali interfluve of Loreto department, Peru.

REMARKS: DNA sequences from this species were identified as Marmosops “Gálvez” in the phylogenetic analyses reported by Díaz-Nieto et al. (2016b). The closest relatives of M. soinii are M. ocellatus and a still undescribed form from eastern Peru and western Brazil (M. “Juruá” sensu Díaz et al., 2016b). A morphological description, summary statistics of external and craniodental measurements, and morphological comparisons with closely related congeners are in Voss et al. (2019).
