The type specimen has the U3 is subequal in size to the 4th. Distribution. Known from three localities in Chiapas , México , ( Carraway 2007 ; Hall 1981 ). Diagnosis. Sorex cristobalensis is a member of the Sorex salvini species group. It is the largest of the species group south of the Isthmus of Tehuantepec ( Table 1 ). The color of the pelage is a dull Clove Brown above, slightly paler ventrally, tail slightly bicolor. Specimens from near El Triunfo, Chiapas , have a more reddish brown dorsum. Usually, U3 is taller than U4. Description. Sorex cristobalensis averages larger in most skull measurements compared to S. salvini ( Table 1 ). The S. cristobalensis has a relatively wider and longer rostrum than S. salvini . Compared to the new species from Honduras , S. cristobalensis has a greater maxillary toothrow length. Sorex cristobalensis has a much longer rostrum than S. stizodon . It is smaller in all measurements than S. sclateri . Ecology. Sorex cristobalensis is high elevation species. Carraway (2007) reviewed the ecology. Reproductive information is lacking. Specimens examined (5).
