Thylamys venustus is distributed at low- to mid-elevations in the Andes from Central Bolivia southward into northern Argentina.
Biogeographic Regions: neotropical (Native )
Little is known about the food habits of this species. Like other Thylamys species, Thylamys venustus likely consumes insects and perhaps occasionally eats small vertebrates, leaves, fruit, seeds, and carrion (Palma 1997).
Primary Diet: carnivore (Insectivore )
Thylamys venustus likely acts as an important predator to many arthropod species and perhaps some small vertebrates. It is likely prey to both bird and medium-sized mammals, such as owls and foxes. It is also likely host to many ecto- and endoparasites. More specific information about the ecosystem role of Thylamys venustus is not presently available.
There are no known positive effects of Thylamys venustus on humans.
There are no known negative effects of Thylamys venustus on humans.
This species is listed as "Data Deficient" by the IUCN.
IUCN Red List of Threatened Species: data deficient
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.
Communication Channels: visual ; tactile ; acoustic ; chemical
Perception Channels: visual ; tactile ; acoustic ; vibrations ; chemical
Thylamys venustus primarily inhabits mid-level montane forests and seasonally dry forests between 350 and 4000 meters above sea level in the eastern Andes. This species overlaps in distribution with Thylamys sponsorius, Thylamys pallidior, and Thylamys pusillus.
Range elevation: 350 to 4000 m.
Habitat Regions: tropical ; terrestrial
Terrestrial Biomes: forest ; mountains
Like other members of its genus, Thylamys venustus 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 grayish ventral region. This species is very similar in morphology to its sister species Thylamys sponsorius, though it tends to be slightly smaller. Like Thylamys sponsorius, this species has a relatively long tail that is considerably longer than its body. Giarla et al. (2010) report head and body lengths that range from 84 to 110 mm (average 96 mm) and tail lengths that range from 111 to 138 mm long (average 126 mm).
Range length: 195 to 248 mm.
Average length: 222 mm.
Other Physical Features: endothermic ; bilateral symmetry
Like other small mammals, Thylamys venustus is likely well adapted to avoiding predators by being nocturnal and inconspicuous. No records of known predators are available.
Anti-predator Adaptations: cryptic
Little is known about the mating system in Thylamys venustus.
Little is known about the general reproductive behavior of Thylamys venustus.
Key Reproductive Features: gonochoric/gonochoristic/dioecious (sexes separate); sexual ; fertilization ; viviparous
Little is known about parental investment in Thylamys venustus. Like all marsupials, females nurse their highly altricial young. However, because members of the genus Thylamys lack a pouch (marsupium), the young must cling to their mother's venter.
Parental Investment: altricial ; female parental care ; pre-fertilization (Provisioning, Protecting: Female); pre-hatching/birth (Provisioning: Female, Protecting: Female); pre-weaning/fledging (Provisioning: Female, Protecting: Female)

Die Cinderella-Fettschwanzbeutelratte (Thylamys venustus) kommt in Bolivien in den Departamentos Cochabamba, Chuquisaca, Tarija und im Westen von Santa Cruz, sowie im nordwestlichen Argentinien in den Provinzen Jujuy und Tucumán vor.[1]
Die Tiere erreichen eine Kopfrumpflänge von 8,4 bis 11 cm, haben einen 11,1 bis 13,8 cm langen Schwanz und erreichen ein Gewicht von 12 bis 26,5 g. Der Schwanz hat in der Regel eine Länge von 130 % der Kopfrumpflänge. Er ist auf der Oberseite braun und unten grau und kann als Fettspeicher dienen. Das Rückenfell und die Kopfoberseite sind graubraun bis zimtbraun. Wie bei Fettschwanzbeutelratten üblich sind die Haare gebändert mit drei unterschiedlichen Farbzonen. Die Haare des Bauchfells sind an der Basis grau und an den Spitzen weißlich oder gelblich. Die Augen sind von schwarzen Ringen umgeben. Die Ohren sind groß und hellbraun gefärbt. Vorder- und Hinterpfoten sind weißlich. Die Weibchen haben keinen Beutel. Die Anzahl der Zitzen ist unbekannt. Der Karyotyp der Cinderella-Fettschwanzbeutelratte besteht aus einem Chromosomensatz von 2n=14 Chromosomen (FN=20).[1]
Die Cinderella-Fettschwanzbeutelratte kommt in den feuchten Wäldern der Yunga, im Chaparral, in verbuschtem Gelände und vom Menschen kultiviertem Land in Höhen von 250 bis 4000 Metern vor. Über ihre Ernährung und ihre Aktivitätsmuster liegen bisher keine Informationen vor. Weibchen mit Jungtieren an den Zitzen wurden im Februar und Oktober gefangen, selbstständige Jungtiere von Februar bis Mai.[1]
Die Cinderella-Fettschwanzbeutelratte wurde erstmals im Jahr 1902 durch den britischen Zoologen Oldfield Thomas beschrieben und der Eleganten Fettschwanzbeutelratte (damals Marmosa elegans) als Unterart zugeordnet. Heute gilt sie als eigenständige Art und wird in die Gattung der Fettschwanzbeutelratten (Thylamys) gestellt. Thylamys cinderella ist ein Synonym der Art.[1]
Die IUCN macht über eine eventuelle Gefährdung von Cinderella-Fettschwanzbeutelratte keine Angaben, da zu wenig Daten vorliegen.[2] Ihr Verbreitungsgebiet ist teilweise dicht von Menschen besiedelt und große Teile des Habitats sind zu Ackerland umgewandelt worden. Im Verbreitungsgebiet gibt es mehrere Schutzgebiete. In keinem wurde die Art bisher allerdings nachgewiesen.[1]

The buff-bellied fat-tailed mouse opossum (Thylamys venustus) is a species of opossum in the family Didelphidae.[3] It is found in the transitional and humid forests of northern Argentina and southern Bolivia.[1] Its dorsal fur is cinnamon brown. Most of its ventral fur is gray-based, but its chest, throat, and the thoracic midline (the midline of the thorax, which ranges from the throat to the top of the abdomen) are not gray-based. The postorbital ridges are absent in the young and weakly developed in adults.[4]
Initially classed as a Marmosa elegans subspecies,[5] it was subsequently raised to species status in 1933.[6] There are four synonyms: Marmosa elegans venusta (Thomas, 1902, Cochabamba), Marmosa elegans cinderella (Thomas, 1902, Tucumán Province), Marmosa elegans sponsoria (Thomas, 1921, Jujuy Province) and Marmosa janetta (Thomas, 1926, Tarija Department) with cinderella and sponsoria actually being one taxon and a subspecies of venustus; janetta is the largest of all and has cream-white ventral fur with plumbeous bases.[7]
Its conservation status is not exactly known; it occurs in an area currently being developed, and while its range overlaps several protected areas, it is uncertain if it occurs in any of them.

Thylamys venustus[2] är en pungdjursart som först beskrevs av Thomas 1902. Thylamys venustus ingår i släktet Thylamys och familjen pungråttor.[3][4] IUCN kategoriserar arten globalt som otillräckligt studerad.[1] Inga underarter finns listade.[3]
Pungdjuret förekommer i södra Bolivia och norra Argentina. Arten vistas där i låglandet och upp till 2000 meter höga bergstrakter (enligt en annan källa upp till 4000 meter[5]). Habitatet utgörs av fuktiga skogar, buskmarker och människans odlingar.[1]
Arten blir 84 till 110 mm lång (huvud och bål) och har en 111 till 138 mm lång svans. Den har mörk päls på ryggen, något ljusare päls på kroppssidorna och ännu ljusare gråaktig päls på buken. Liksom andra medlemmar av släktet Thylamys kan den lagra fett i svansen. Thylamys venustus tillhör pungsdjuren men honor saknar pung (marsupium).[5]
Antagligen lever individerna utanför parningstiden ensam. De är aktiv på natten och äter främst insekter. Allmänt antas vara levnadssättet lika som hos andra arter av släktet Thylamys.[5]
