There is insufficient information on the feeding habits of Bibimys chacoensis. However, stomach content analysis of both Akodon cursor and Akodon boliviensis, close relatives of Bibimys chacoensis, show that typical Akodon diet consists of plant material, seeds, and insects. The stomach contents of A. azarae is 25% plant matter and 75% invertebrates.
Although little information is available on the diet of Bibimys chacoensis, this species likely consumes insects and may help control insect pest species. As a small rodent, this species likely consumes various types of seeds and may be an important seed disperser for various plants throughout its native range. Due to its fossorial lifestyle, B. chacoensis helps aerate soil and increases water penetration into the soil. Although little information is available on potential endo- and ectoparasites specific to this species, Bibimys chacoensis is known to host a recently discovered species of sucking lice, Hoplopleura aitkeni.
Ecosystem Impact: soil aeration

There is no information on the potential positive effects of Bibimys chacoensis on humans.
There is no information on the potential negative impacts of Bibimys chacoensis on humans.
Although Bibimys chacoensis lives in a confined region of Argentina and Paraguay, this species is listed as "least concern" by the IUCN Red List of Threatened Species and is not protected under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
US Federal List: no special status
CITES: no special status
State of Michigan List: no special status
IUCN Red List of Threatened Species: least concern
Communication in Bibimys chacoensis is not well understood. Other sigmodontine rodents perceive their environment using vision, hearing, touch, smell, and taste. Sigmodontines primarily use auditory or chemical cues for communication with conspecifics.
Communication Channels: chemical
Other Communication Modes: pheromones ; scent marks
Perception Channels: visual ; tactile ; acoustic ; chemical
The genus Bibimys is very diverse and poorly understood. Trapping members of this genus is difficult and for that reason, many specimens are very old and badly preserved. Currently, there are only three species of Bibimys, however, the validity of the three species, Bibimys chacoensis, Bibimys labiosus, and Bibimys torresi, has not been researched extensively.
Chaco crimson-nosed rats are native to the Neotropical region and can be found in the province of Misiones in northeastern Argentina and in southeastern Paraguay.
Biogeographic Regions: neotropical (Native )
Bibimys chacoensis lives in wet regions of the Chaco grasslands in northeastern Argentina and in southeastern Paraguay. They generally live around 125 m of elevation but are not found above 300 m.
Range elevation: 300 (high) m.
Average elevation: 125 m.
Habitat Regions: temperate ; tropical ; terrestrial
Terrestrial Biomes: savanna or grassland
The chaco crimson-nosed rat's lifespan has not been documented.
Chaco crimson-nosed rats are members of the subfamily Sigmodontinae, which have a dental formula of 1/1, 0/0, 0/0, 3/3, for a total of 16 teeth. This species has short ears, a short tail, and enlarged claws. Like other members of Bibimys, B. chacoensis can has a crimson nose. Lateral pelage of the torso tends to have a buffy appearance and is dark along the dorsal surface of the body. Ventral pelage is whitish and slight buffy in appearance. On average, chaco crimson-nosed rats weigh 28.6 g and have a total body length of 162.9 mm. Tail length ranges from 35 mm to 81 mm, with an average of 66.14 mm. Hind foot length (including the claw) averages 21.9 mm and ranges from 20 to 25 mm. Ear length averages 16.3 mm and ranges from 16 mm to 18 mm. The number of roots of the third molar can be used to distinguish Chaco crimson-nosed rats from other members of the genus Bibimys. Chaco crimson-nosed rats have 3 roots, while most other members of Bibimys have only 2.
Range mass: 19.2 to 40.5 g.
Average mass: 28.6 g.
Range length: 132 to 185 mm.
Average length: 162.9 mm.
Other Physical Features: endothermic ; homoiothermic; bilateral symmetry
The only documented predator of this species is the white-tailed hawk (Buteo albicaudatus), however other raptors and carnivores likely prey on this species as well. The small size of Bibimys chacoensis and its fossorial behavior help protect it from predators. Its brown pelage likely helps camouflage it from potential predators.
Known Predators:
Anti-predator Adaptations: cryptic
Currently, there is no information available on the mating system of Bibimys chacoensis.
Little information is available on the reproductive behavior of Bibimys chacoensis. Members of the genus Akodon, close relatives to Bibimys, typically have breeding seasons extending from August to May but may vary according to climate and resource availability. Litters consist of 3 to 4 young and there are usually 2 litters per year. In one species of Akodon, Akodon azarae, implantation may be delayed and gestation last 22.7 days on average.
Key Reproductive Features: iteroparous ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; viviparous
Little is know of parental care in Bibimys chacoensis. As mammals, females nurse and care for their young until weaning is complete. Akodon azarae, a member of the closely related genus Akodon, weans its young by 14 to 15 days old.
Parental Investment: altricial ; pre-fertilization (Provisioning, Protecting: Female); pre-hatching/birth (Provisioning: Female, Protecting: Female); pre-weaning/fledging (Provisioning: Female)

Bibimys chacoensis is a species of small rodent of the family Cricetidae living in the north-central part of Southern Cone of South America. The common name of this species is Chaco crimson-nosed rat (in Spanish: ratón de hocico rosado norteño [Northern pink-nosed mouse]). It is one of the three species currently recognized under the genus Bibimys.
The species was described in 1931 by zoologist Harold H. Shamel, under the denomination of Akodon chacoensis. The etymology of this species is a toponym for the locality where the type material was collected, Chaco Province in Argentina. The exact locality in the label is: “Las Palmas, provincia del Chaco, Argentina”. In 1980, Argentinian mammalogist, Elio Massoia, transferred it to genus Bibimys.
Bibimys chacoensis is considered to be an endemic species of the gallery forests and open spaces of the Humid Chaco region between the provinces of Formosa Province, Chaco, and Misiones Province. It has been also reported from Paraguay.
According to the IUCN Red List of Threatened Species, Bibimys chacoensis is listed as a species of least concern. However, Argentinian conservationist Juan Carlos Chebez (1962 - 2011) placed this species under threat in a paper published in 2009. Very little is known about the reproduction, maternal care, lifespan, longevity, behaviour, and economic impact of this species.

Bibimys chacoensis[2][3][4] är en däggdjursart som först beskrevs av Henry Harold Shamel 1931. Bibimys chacoensis ingår i släktet rödnosade råttor, och familjen råttdjur.[5][6] IUCN kategoriserar arten globalt som livskraftig.[1] Inga underarter finns listade i Catalogue of Life.[5]
Denna gnagare förekommer i nordöstra Argentina och angränsande delar av Paraguay. Arten vistas i gräsmarker, ofta nära regnskogar.[1]
Arten når en absolut längd av 13 till 18,5 cm, inklusive en 3,5 till 8 cm lång svans. Den genomsnittliga vikten är 28,5 g. Pälsen har på ovansidan en brunaktig färg och undersidan är ljusare brun till vit. Klorna vid bakfötterna är kraftiga och hela foten är med klorna 2,0 till 2,5 cm lång. Den tredje molara tanden har tre rötter, motsvarigheten hos andra arter av släktet har bara två rötter. Tandformeln är I 1/1 C 0/0 P 0/0 M 3/3, alltså 16 tänder.[7]
Levnadssättet antas vara lika som hos andra rödnosade råttor.[7]
