Marmosops (Sciophanes) marina Ferreira et al., 2020

TYPE MATERIAL AND TYPE LOCALITY: UFMT 4078, the holotype by original designation, consists of the skin and skull of an adult male collected at Fazenda São José (9.63° S, 56.08° W)

on the right bank of the Rio Teles Pires, Mato Grosso state, Brazil.

SYNONYMS: None.

DISTRIBUTION: Marmosops marina occurs south of the Amazon between the Rio Xingu and the Rio Madeira in the Brazilian states of Pará, Mato Grosso, and Rondônia ( Ferreira et al., 2020: fig. 5).

REMARKS: Guimarães et al. (2021) applied species-delimitation algorithms to DNA sequence data from Marmosops marina collected on both banks of the Rio Tapajós and concluded that the population between the Tapajós and Madeira rivers is genetically distinct from that in the Xingu- Tapajós interfluvium (which includes the type locality); however, it is not clear that these populations are phenotypically distinguishable, and there seems to be no point in restricting the application of the name as they suggest. Morphological traits described by Ferreira et al. (2020) clearly place this species in the Parvidens Group of Díaz-Nieto and Voss (2016). Within the Parvidens Group, M. marina appears to be the sister species of a clade that includes M. pinheiroi and M. woodalli based on phylogenetic analyses of DNA sequence data reported by Guimarães et al. (2021).
