“ Miraflores , San Ignacio, Cajamarca, Peru (5° 12’ S and 79° 12° W) at 2,800 m above sea level.” GoogleMaps
Cryptotis evaristoi is in the C. thomas: group based primarily on its morphology and distribution. Molecular data places it close to C. montivagus and C. niausa in the C. thomasi
group and also close to the C. mexicanus group. Monotypic.
Distribution. Tabaconas Namballe National Sanctuary in NW Peru. View Figure
Descriptive notes. Head-body 70-96 mm, tail 29-37 mm, hindfoot 14-17 mm; weight 11-16 g. Evaristo’s Small-eared Shrew is very large. Dorsum is dark grayish brown, venter is paler brown, and individual hairs are silvery gray with lighter tips. Forefeet are somewhat enlarged and robust, with long pointed claws. Tail is short (40% of head-body length), unicolored brownish, and covered with short hairs. Eyes are diminutive, and ears are small and barely visible under fur. Evaristo’s Small-eared Shrew is distinguished from other species of Cryptotis byits inflated cranium in dorsal view being more rounded to hexagonal, fronto-occipital suture being rounded to triangular in shape, narrow nasal with wide opening, anterior border of nasal not having spine-shaped process, and pterygoid fossa being wider and shorter. Secondary cusp of upper incisors is very reduced and about one-third the size of anterior cusp; interorbital parallel in dorsal view and not convergent; fourth unicuspid is not in line with other unicuspids; posterior border of lower incisor reaches anterior border of P*; optic foramen partially visible in lateral view of skull; and fourth unicuspid is small and usually visible in labial view. Teeth are reddish and there are four unicuspids.
Habitat. Piramo and montane wet forest at elevations of 2700-3280 m.
