San Cristobal Shrew
French: Musaraigne de San Cristobal / German: San-Cristobal-Spitzmaus / Spanish: Musarana de San Cristobal
Taxonomy. Sorex saussurei cristobalensis H. H. T. Jackson, 1925 ,
“San Cristobal , altitude 8,400 feet [= 2560 m |, State of Chiapas, Mexico.” Restricted by L.. N. Carraway in 2007 to “latitude 16-75°N, longitude 92.63°W.”
Sorex cristobalensis was described as a subspecies of S. saussurei and then was recognized as a subspecies of S. veraecrucis . Recently, S. cristobalensis was recognized as a separate species following morphometric studies that aligned populations attributed to it with other members of the salvini group. Genetic studies by N. Esteva and colleagues in 2010 also support this because specimens now attributed to S. cristobalensis (then considered S. veraecrucis ) clustered with some specimens of S. salvini (then considered S. saussurer). Monotypic.
Distribution. Known only from three localities in Chiapas, SE Mexico. View Figure
Descriptive notes. Head-body 60-69-5 mm, tail 46-5-49 mm, hindfoot 13-14 mm; weight 6 g. The San Cristobal Shrew is relatively small. Dorsum is medium brown, hips and rump are light brown, and venteris light red brownish gray. Tail is ¢.80% of head-body length and slightly bicolored, medium brown above and slightly paler below. It has deep interdenticular space on lower first incisors that are pigmented in two sections. There are five unicuspids,first and second are large, third is barely taller than fourth, and fifth is minute. Teeth are pigmented dark red.
Habitat. Upper highland moist forests at elevations of ¢.1900-2500 m.
Food and Feeding. No information.
Breeding. No information.

Movements, Home range and Social organization. No information.
Status and Conservation. Not assessed on The IUCN Red List. The San Cristobal Shrew is known from few specimens in three localities, although its distribution might be wider. Nothing is known aboutits threats, and additional research is needed.
