Sorex cristobalensis Jackson, 1925 

Cristobal Shrew

Sorex saussurei cristobalensis Jackson, 1925: 129  . Type locality: “San Cristobal, altitude 8,400 feet, State of Chiapas, Mexico.” Sorex veraecrucis cristobalensis: Carraway, 2007: 62  . 

Sorex salvini cristobalensis: Ramírez-Pulido et al. 2014: 48 

Holotype. Number 75883, U. S. National Museum, Biological Survey Collection; adult female, skin and skull; taken September 19, 1895, by E. W. Nelson and E. A. Goldman, original number 8429. Measurements for the holotype are: Tot, 116; Tail, 46.5; HF, 13.5; CBL17.8; GLS, 18.4; LR, 7.43; PL, 7.88; LUT, 2.63; LMT, 4.73; CB, 8.43; widWM2, 4.93; LIB, 3.79; CD, 5.33; LM, 7.32; HC, 3.55. 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.
