Marmosa (Micoureus) alstoni (J.A. Allen, 1900)

TYPE MATERIAL AND TYPE LOCALITY: AMNH 11790 About AMNH /16210, the holotype by original designation, consists of the skin and skull of an adult male collected at Tres Ríos (9.90° N, 83.98° W; 1219 m), Cartago province, Costa Rica GoogleMaps .

SYNONYMS: None.

DISTRIBUTION: As currently understood (see Remarks, below), Marmosa alstoni is only known from a handful of localities in the central highlands of Costa Rica (Voss et al., 2021: fig. 2).

REMARKS: Marmosa alstoni was once thought to range from Belize to Colombia ( Tate, 1933; Hall, 1981; Gardner and Creighton, 2008a) and to include M. nicaraguae as a synonym, but a recent revision of the Alstoni Group of Marmosa restricted the application of this name to specimens collected in the central highlands of Costa Rica (Voss et al., 2021).
