and body length is 90-135 mm and tail length is from 93-139
mm. Weights average from 25-40.8 g. for males and 16.5-25.4
for females. The pelage is made up of different textures, causing
an uneven appearance to the soft, thick fur. The coloration
tends to be darker above ranging from dark browns to nearly
black. The nonprehensile tail is nearly naked and is the same
color as the back. The small ears protrude above the fur and
the eyes are very small. The head is elongate like that of a
true rat or shrew. L. inca is the best known of all the
species. It has five digits on each foot, the forefeet having
small outer toes with blunt claws and sharply curved nails on
the remaining three. The hind feet have well developed curved
claws on all toes but the great toe, which is small with a small
L. inca is nocturnal and terrestrial, preferring cool,
wet areas with heavy vegetation. They are found in alpine forests
and meadow zones of the Andes at altitudes from 1,500-4,000
meters. To travel from one area to another, they build runways
through the surface vegetation.
The sight of L. inca is poor, but the hearing and sense
of smell are well-developed. Long thought to be largely insectivorous,
L. inca has been found to easily kill newborn rats.
Breeding season is believed to be early July, as specimens trapped
in August were suckling young.
L. inca is found in the S Andean Peru and adjacent Bolivia.
