Scientific Name: Neomicroxus latebricola (Anthony, 1924)
Common Name(s):
English Ecuadorean Grass Mouse, Ecuadorean Akodont
Akodon latebricola (Anthony, 1924)

Taxonomic Notes: This amended version of the 2008 assessment has been created because Akodon latebricola has been transferred to the new genus Meomicroxus (Alvarado-Serrano and D'Elía 2013). The species name in the text has also been updated accordingly and various typographical errors corrected.

Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii) ver 3.1
Year Published: 2016
Date Assessed: 2008-07-01
Assessor(s): Boada, C., Gómez-Laverde, M. & Anderson, R.
Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
This species is Vulnerable because it has a small extent of occurrence (less than 20,000 km²), it is known from less than 10 locations and there is continuing decline in area and quality of habitat.

Geographic Range [top]

Range Description:This species is known from only a few localities and is suspected to occur in the Cordillera Oriental, 2,400 to 3,840 m, in north central Ecuador (Pichincha, Napo and Tungurahua Provinces) (Musser and Carleton 2005, Voss 2003). It could occur in southern Colombia, but has not been yet recorded (M. Gómez-Laverde pers. comm.).

Population [top]

Population:It is rare and poorly known (D. Tirira pers. comm.).
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:Yes

Habitat and Ecology [top]

Habitat and Ecology:This rodent is present in the shrubby paramo/forest ecotone, in subalpine Rain Forest, in grassy glades surrounded by subalpine Rain Forest, and in grassy paramo. All recorded captures were on the ground: in runways under dense bunch grass, among mixed grasses, and mossy shrubs, and under moss mats or low herbs. Several individuals of Neomicroxus latebricola were captured in broad daylight, between the time when traps were checked just after dawn and when they were rebaited in the late afternoon (Voss 2003).

Threats [top]

Major Threat(s): The major threats are habitat loss and fragmentation, due to conversion of its native high elevation grassland habitat to agriculture.

Conservation Actions [top]

Conservation Actions: This rodent occurs in several protected areas (D. Tirira pers. comm.).
