Marmosa
(
Micoureus
)
perplexa
Anthony, 1922
TYPE
MATERIAL AND
TYPE
LOCALITY:
AMNH
47188, the
holotype
by original designation, consists of the skin and skull of a young adult female collected at Punta Santa Ana (
3.83° S
,
79.55° W
;
1113 m
),
Loja province
,
Ecuador
.
SYNONYMS: None.
DISTRIBUTION:
Marmosa perplexa
is known from the Pacific lowlands and western Andean foothills of southwestern
Ecuador
(
El Oro
,
Loja
) and northwestern
Peru
(
Cajamarca
,
Tumbes
) (Voss and Giarla, 2021: fig. 2).
REMARKS: This species has long been treated as a synonym of
Marmosa phaea
, which it externally resembles. However,
M. perplexa
and
M. phaea
are not sister taxa, they have highly divergent mtDNA sequences, and they differ in several details of craniodental morphology (Voss and Giarla, 2021).
