Osgood’s Small-eared Shrew
French: Musaraigne d'Osgood / German: Osgood-Kleinohrspitzmaus / Spanish: Musarana de orejas pequenas de Osgood
Other common names: Osgood's Shrew
Taxonomy. Blarina osgoodi Stone, 1914 ,
“ Hacienda Garzon, Mt. Pichincha, 10,500 ft. [= 3200 m] altitude,” Pichincha , Ecuador.
Cryptotis osgoodi is currently in the C. thoma- si group based on morphology and genetic data, and it is sister to C. equatoris based on recent phylogenetic studies. C. osgoodi is usually included as a subspecies of C. equatoris , although it was recognized as a distinct species based on morphometric
studies. Monotypic.
Distribution. Andes of NC Ecuador. View Figure
Descriptive notes. Head-body 54-83 mm,tail 24-35 mm, hindfoot 12-15 mm; weight 6-13 g. Osgood’s Small-eared Shrew is small to medium-sized, with long tail but shorter than that of the Ecuadorean Small-eared Shrew ( C. equatoris ). Dorsum is dark blackish brown, and venter is somewhat paler. Forefeet are somewhat more slender than in other species of the C. thomasi group and have long pointed claws. Tail is relatively long (c.40% of head-body length), unicolored brownish, and covered with short hairs. Eyes are diminutive, and ears are small and barely visible under fur. Fourth unicuspid is relatively large and visible in lateral view of skull. Zygomatic plate is narrow, and palatal bone is also narrow compared with the Ecuadorean Small-eared Shrew. Teeth are reddish, and there are four unicuspids.
Habitat. Apparently wet montane tropical forest and paramo at elevations of 1700-3700 m.
Food and Feeding. No information.
Breeding. No information.
Activity patterns. No information.
Movements, Home range and Social organization. No information.
Status and Conservation. Not assessed on The IUCN Red List. Virtually nothing is known of the ecology and threats of Osgood’s Small-eared Shrew, but it is known from a relatively wide distribution compared with other species of Cryptotis . Osgood’s Small-eared Shrew might be threatened by habitat destruction from deforestation for agricultural expansion, but if it is similar to the Ecuadorean Small-eared Shrew, it might be resillent in degraded regions.
