Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Chordata Mammalia Rodentia Heteromyidae

Scientific Name: Heteromys adspersus (Peters, 1874)
Common Name(s):
English Panamanian Spiny Pocket Mouse
Liomys adspersus (Peters, 1874)
Taxonomic Source(s): Hafner, J.C., Light, J.E., Hafner, D.J., Hafner, M.S., Reddington, E., Rogers, D.S. and Riddle, B.R. 2007. Basal clades and molecular systematics of heteromyid rodents. Journal of Mammalogy 88: 1129-1145.
Taxonomic Notes: Synonymized under Heteromys: Hafner et al. (2007) confirmed paraphyly of Liomys relative to Heteromys, placing Liomys in synonymy with Heteromys. This species (formerly Liomys adspersus) and its sister species, H. salvini, form a clade that is basal to the other members of the genus and for which the subgeneric or generic name Schaeferia has been suggested (von Lehmann and Schaefer 1979).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-06-10
Assessor(s): Roach, N. & Naylor, L.
Reviewer(s): Amori, G.

This species is listed as Least Concern in view of its wide distribution, presumed large population, tolerance of a broad range of habitats, occurrence in a number of protected areas, and because it does not appear to be under threat and is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.

Habitat and Ecology [top]

Habitat and Ecology:This rodent occurs in dry, deciduous forest, thorn scrub, and weedy fields. Appears to tolerate a degree of habitat disturbance.

Most of its ecology is similar to L. salvini (Reid 1997). It eats palm nuts (Scheelea rostrata and Bactris balanoides), other seeds, green plant material, and insects. Breeding occurs from December to May in central Panama (Reid 1997).
Generation Length (years):2

Threats [top]

Major Threat(s): No major threats are known. However, it could be subject to agrochemicals in part of its range (Samudio pers. comm.).

Conservation Actions [top]

Conservation Actions: It occurs in several protected areas.
