Marmosa (Micoureus) nicaraguae Thomas, 1905

TYPE MATERIAL AND TYPE LOCALITY: BMNH 5.10 .31.5, the holotype by original designation, consists of the skin and skull of an adult male collected at Bluefields (12.00° N, 83.75° W; sea level), South Caribbean Autonomous Region, Nicaragua .

SYNONYMS: None.

DISTRIBUTION: Examined specimens of Marmosa nicaraguae are from just three localities in the Caribbean coastal lowlands of Nicaragua and Costa Rica, but a photographed individual from the Pacific foothills of the Cordillera Tilarán (in Costa Rica) suggests that the species may be more widely distributed (Voss et al., 2021: fig. 2).

REMARKS: Marmosa nicaraguae was formerly considered to be a subspecies of M. alstoni (e.g., by Tate, 1933; Hall, 1981), but evidence that these taxa are morphologically and genetically distinct was discussed by Voss et al. (2021).
