Leptomys elegans is a New Guinea forest rodent. The review describes long, narrow hind feet and a tail that can equal or exceed head-and-body length as traits of its genus.
The genus Leptomys has short, dense fur, tawny-brown upperparts, and white to grayish-white underparts. A slender muzzle, elongated hind feet, and a tail as long as or longer than the body are also described as genus traits.
The review characterizes Leptomys species as terrestrial, nocturnal, and largely carnivorous, nesting underground in the forest floor. It also says biological information for the genus remains limited.
An extinction-risk assessment has not been added yet.
