The lesser Wilfred's mouse (Juliomys pictipes) is a species of South American rodents of the family Cricetidae.^[2] It was first described by Wilfred H. Osgood under the name Thomasomys pictipes, then into the genus Wilfredomys, and now known as Juliomys pictipes.^[3] The lesser Wilfred's mouse is endemic to northeastern Argentina and southeastern Brazil.^[4] Its physical appearance ranges from dark brown to light orange coloration and the typical size is small to medium.^[3] This species is arboreal, spending most of its time trees and living in the local forests at altitudes from sea level to 2000 m.^[1] Currently, this species is listed as Least Concern by the IUCN, but, threats include livestock farming, ranching, and wood harvesting.^[4]

Taxonomy

Juliomys pictipes was first discovered by Osgood in 1933.^[5] It was originally named Thomasomys pictipes.^[6]^[3] For several decades, the placement of this species was uncertain and fairly recently changed to Juliomys pictipes to fit under the subfamily of Sigmodontinae rodents.^[2] Currently, there are three species under the genus of Juliomys. The taxon identifier is 89132.^[7]

Description

This animal is considered to be small to medium sized Sigmodontinae rodents.^[2] They are dark-brown to light-orange brown.^[7] Other characteristics include having long soft fur with a brownish ochraceous dorsum.^[8] This small-bodied animal is a pentalophodont with a tail longer than its head and body.^[9] Juliomys pictipes have short, broad feet with 6 plantar pads.^[3] In addition, the skull has identifying features including having a short rostrum and rounded braincase.^[2] Another diagnostic characteristic is the presence of an open slit in the suture between the frontal bones. Lastly, its karyotype has 2n = 36, FN = 34.^[8]

Distribution and habitat

It is found in northeastern Argentina and southeastern Brazil and limited to the tropical and subtropical moist forests of those countries.^[9] The type locality was first discovered in Misiones, Argentina and occurs in the Atlantic forest.^[10]

Ecology

The species is arboreal.^[7] A baby of this species is often called a pinkie, kitten or pup.^[7] The females are called doe and males are called buck.^[7] Groups of this species are called a nest, colony, harvest, horde or mischief.^[11]

Status

The Lesser wilfred's mouse is listed as Least Concern.^[11] But, threats that increase mortality or decrease quality of life include livestock farming, ranching, and wood harvesting.^[4]
