Cryptotis endersi

French: Musaraigne d'Enders / German: Enders-Kleinohrspitzmaus / Spanish: Musarana de orejas pequenas de Enders

Other common names: Enders’s Shrew

Taxonomy. Cryptotis endersi Setzer, 1950,

“ Cylindro, Province of Chiriqui, Panama.”

Cryptotis endersi is in the C. thomas: group based on morphology, although no specimens have been included in a phylogenetic study. Monotypic.

Distribution. Highlands of W Panama.

Descriptive notes. Head—body 81 mm, tail 49 mm, hindfoot 15 mm. No specific data are available for body weight. Enders’s Small-eared Shrew is large, with relatively

long tail. Pelage is long; dorsum is dark blackish brown; and venter is somewhat lighter charcoal gray. Forefeet are somewhat slender than in other species of the C. thomasi group and have long pointed claws. Tail is very long for the genus (49-60% of headbody length), unicolored brownish, and covered with short hairs. Eyes are diminutive, and ears are small and barely visible under fur. Fourth unicuspid is in line with unicuspid tooth row and is clearly visible in lateral view of skull. Braincase is larger than in the sympatric Talamancan Broad-clawed Shrew ( C. gracilis). Teeth are reddish, and there are four unicuspids.

Habitat. Probably wet montane evergreen forests, recorded at elevations of 1200-1850 m.

Food and Feeding. No information.

Breeding. No information.

Movements, Home range and Social organization. No information.

Status and Conservation. Classified as Endangered on The IUCN Red List. Enders’s Small-eared Shrew is apparently rare (only known from subadult type specimen and single adult specimen collected in 1980) and has a restricted distribution that is threatened by deforestation and urban/agricultural development. Virtually nothing is known of its ecology, and additional research is needed.
