Abstract

The broad-clawed shrew Cryptotis griseoventris Jackson, 1933, is poorly known ecologically and behaviorally because distributional records are relatively scarce. Here, we provide new records based on 11 specimens deposited in mammal collections, more than 50 years since the last confirmed record. Historical records and specimens are reexamined and discussed. We suggest that C. griseoventris occurs in a small area (<5000 km2) above 2100 m dominated by pine oak and cloud forests in Los Altos de Chiapas, Mexico, and is likely endangered due to habitat deforestation. We also describe the humerus, a useful structure to delimit species and reconstruct phylogenetic relationships within the genus Cryptotis. The morphology of their humerus corroborates its taxonomic relatedness with the Cryptotis goldmani species group and yields a more comprehensive knowledge of the ecology and evolution within this group.
