Museum records of this species are sparse. Presently, (Giarla, et al., 2010)appears to be restricted to the provinces of Ancash and Lima in Peru.
This species has been recorded in mountainous and desert habitats in a small part of central Peru. It has been captured from 300 to 3000 meters above sea level. (Giarla, et al., 2010)
- Range elevation
- 300 to 3000 m
- 984.25 to 9842.52 ft
Like other members of its genus, T. elegans, T. pallidior, and ) as described by Giarla et al. (2010). A single specimen of this rare species examined by Giarla et al. (2010) was recorded with a head + body lengths of 109 mm and tail length of 118 mm. (Giarla, et al., 2010)is notable for its incrassate (fattened) tail. The size of the tail varies by season in accordance with food availability. Although this species is a marsupial, females do not have a pouch. This species is tricolored, with darker dorsal fur, paler lateral fur, and a white ventral region. This species is broadly similar to other members of the Elegans Group (which includes
- Average length
- 227 mm
- 8.94 in
Little is known about the mating system in Thylamys elegans, Palma (1997) reported that two adults have never been found in the same nest, suggesting that this species does not form monogamous breeding pairs. (Palma, 1997). For the closely related species
Little is known about the reproductive behavior of this species. No records of its behavior have been published.
No record of this species' lifespan is available.
The home range of this species is not known.
Communication and Perception
Because this species is small and nocturnal, communication between individuals is likely primarily olfactory in nature. Palma (1997) reports that the olfactory and visual regions of another Thylamys species' brain are especially well developed. (Palma, 1997)
Little is known about the food habits of this species. Like other Thylamys species, likely consumes insects and perhaps occasionally eats small vertebrates, leaves, fruit, seeds, and carrion (Palma 1997). (Palma, 1997)
Like other small mammals, (Giarla, et al., 2010)is likely well adapted to avoiding predators by being nocturnal and inconspicuous. No records of known predators are available.

young are born in a relatively underdeveloped state; they are unable to feed or care for themselves or locomote independently for a period of time after birth/hatching. In birds, naked and helpless after hatching.

uses smells or other chemicals to communicate
having markings, coloration, shapes, or other features that cause an animal to be camouflaged in its natural environment; being difficult to see or otherwise detect.
- desert or dunes
in deserts low (less than 30 cm per year) and unpredictable rainfall results in landscapes dominated by plants and animals adapted to aridity. Vegetation is typically sparse, though spectacular blooms may occur following rain. Deserts can be cold or warm and daily temperates typically fluctuate. In dune areas vegetation is also sparse and conditions are dry. This is because sand does not hold water well so little is available to plants. In dunes near seas and oceans this is compounded by the influence of salt in the air and soil. Salt limits the ability of plants to take up water through their roots.
animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a (now extinct) synapsid ancestor; the fossil record does not distinguish these possibilities. Convergent in birds.
